fix: code compliance audit and fix across all services
NestJS (6 services): implement @RequirePermission decorator with SetMetadata+Reflector, register APP_GUARD globally, fix as assertions to type guards, add explicit return types, fix import type for express, fix /metrics implicit any, replace native Error with ApplicationError, remove typeorm remnants, register LifecycleService. teacher-bff: add logger, ApplicationError, GlobalErrorFilter, forward real userId to downstream, log downstream failures, migrate health controller to shared/health. Go (2 services): interface to any, doc comments, CORS dev whitelist, JWT secret fail-fast, push-gateway internal API auth, metrics and readyz endpoints, remove dead code. Python (2 services): lifespan return type, dev_mode to bool, data-ana APIRouter, ai POST body model, ClickHouse async wrapping.

## 3. AI 分配方案（7 AI + 1 coord）
|
||||||
|
|
||||||
|
### 3.1 分配原则
|
||||||
|
|
||||||
|
- **同语言内聚**：一个 AI 负责多个同语言服务，学习成本只付一次
|
||||||
|
- **领域亲缘性**：同类业务放一起（BFF 归 BFF、Python 归 Python）
|
||||||
|
- **工作负载均衡**：Neo4j+ES 的内容服务、ClickHouse 的分析服务复杂度高，不绑太多其他服务
|
||||||
|
- **前端统一**：Module Federation 微前端由一人设计，保证 shell + remote 架构一致
|
||||||
|
- **黄金模板对齐**：已实现的 services 负责 AI 需审计并对齐 classes 标准
|
||||||
|
|
||||||
|
### 3.2 分配矩阵
|
||||||
|
|
||||||
|
| AI 标识 | 语言 | 服务 | 数量 | 阶段归属 |
|
||||||
|
| --------- | ------ | ----------------------------------------------------------- | ---- | -------- |
|
||||||
|
| **ai01** | Go | api-gateway、push-gateway | 2 | P1 + P5 |
|
||||||
|
| **ai02** | TS | iam | 1 | P2 |
|
||||||
|
| **ai03** | TS | teacher-bff、core-edu | 2 | P2 + P3 |
|
||||||
|
| **ai04** | TS | student-bff、parent-bff | 2 | P3 + P4 |
|
||||||
|
| **ai05** | TS | content、msg | 2 | P4 + P5 |
|
||||||
|
| **ai06** | Python | data-ana、ai | 2 | P4 + P5 |
|
||||||
|
| **ai07** | TS | teacher-portal、student-portal、parent-portal、admin-portal | 4 | P2-P6 |
|
||||||
|
| **coord** | — | shared-proto、shared-*、infra/、docs/、CI/CD | — | 跨阶段 |
|
||||||
|
|
||||||
|
### 3.3 为什么这样拆
|
||||||
|
|
||||||
|
| 决策 | 理由 |
|
||||||
|
| ----------------------------- | ------------------------------------------------------------------------------- |
|
||||||
|
| ai02 独立负责 iam | RBAC 三层角色 + DataScope 6 级 + 视口 4 层是整个系统的权限中枢，复杂度最高 |
|
||||||
|
| ai03 teacher-bff + core-edu | 教学域全栈：BFF 聚合 + 核心业务。考试/作业/成绩状态机在一个人手里，不跨 AI 协调 |
|
||||||
|
| ai04 student-bff + parent-bff | 两个 BFF 都是纯聚合层，技术同质（GraphQL + DataLoader），设计模式完全复用 |
|
||||||
|
| ai05 content + msg | 都依赖 ES，content 建索引、msg 查索引，一人设计避免 ES 索引冲突 |
|
||||||
|
| ai07 前端 4 端 | Module Federation shell + remote 架构需一人统一设计，4 端共享组件库和权限体系 |
|
||||||
|
| coord 不写业务代码 | 专注契约管理 + 交叉审查，保证 7 份设计文档的接口一致性 |

## 6. 阶段 1 交付物模板
|
||||||
|
|
||||||
|
每个 AI 阅读完 §4 的文档清单后，必须产出以下确认书：
|
||||||
|
|
||||||
|
```markdown
|
||||||
|
## 模块理解确认书 — [模块名]
|
||||||
|
|
||||||
|
### 1. 我在架构中的位置
|
||||||
|
|
||||||
|
- 层级：Gateway / BFF / Service / Data / Frontend
|
||||||
|
- 上游：谁调用我？
|
||||||
|
- 下游：我调用谁？
|
||||||
|
- 通信方式：HTTP / gRPC / Kafka / WebSocket / 直接 DB？
|
||||||
|
|
||||||
|
### 2. 我的限界上下文
|
||||||
|
|
||||||
|
- 我负责哪些聚合/实体？
|
||||||
|

||||||
|
|
||||||
|
### 3. 我与外部的契约
|
||||||
|
|
||||||
|
- 我消费哪些 proto message（从 shared-proto）？
|
||||||
|
- 我暴露哪些 API 端点或 gRPC 方法或 Kafka 事件？
|
||||||
|
- 错误码前缀是什么？
|
||||||
|
|
||||||
|
### 4. 我的技术栈
|
||||||
|
|
||||||
|
- 语言 / 框架 / ORM / 存储
|
||||||
|
|
||||||
|
### 5. 我的阶段归属
|
||||||
|
|
||||||
|
- 属于 P1-P6 哪个阶段？
|
||||||
|
- 当前阶段目标是什么？
|
||||||
|
- 依赖哪些上游阶段的产出？
|
||||||
|
|
||||||
|
### 6. 我需要对齐的黄金模板项（对照 classes 服务）

## 7. 阶段 2 交付物模板
|
||||||
|
|
||||||
|
每个 AI 在阶段 1 确认书通过 coord 审核后，产出以下架构设计文档：
|
||||||
|
|
||||||
|
```markdown
|
||||||
|
## 模块架构设计文档 — [模块名]
|
||||||
|
|
||||||
|
### 1. 模块内部分层图
|
||||||
|
|
||||||
|
[画图：Controller → Guard → Service → Repository → DB 调用链]
|
||||||
|
[标注中间件、Guard、Filter 的拦截点]
|
||||||
|
|
||||||
|
### 2. 领域模型
|
||||||
|
|
||||||
|
- 聚合根：有哪些？
|
||||||
|
- 实体/值对象：有哪些？
|
||||||
|
- 聚合间如何通信？（同服务内直接调用 / 跨服务走事件）
|
||||||
|
|
||||||
|
### 3. 数据模型
|
||||||
|
|
||||||
|
- 有哪些表？（列出 schema，标注字段类型、约束）
|
||||||
|
- 每张表的索引策略（主键、唯一索引、查询索引）
|
||||||
|
- 读写分离策略（哪些走主库、哪些走读模型）
|
||||||
|
|
||||||
|
### 4. API 设计
|
||||||
|
|
||||||
|
| method | path | 权限 | 请求/响应结构 | 说明 |
|
||||||
|
| ------ | ---- | ---------- | ------------- | ---- |
|
||||||
|
| POST | /xxx | XXX_CREATE | { ... } | ... |
|
||||||
|
|
||||||
|
### 5. 事件设计（如适用）
|
||||||
|
|
||||||
|
- 我发布哪些领域事件？触发时机是什么？
|
||||||
|
- 我消费哪些外部事件？消费后做什么？
|
||||||
|
- 事件 Topic 名称（遵循 `edu.<domain>.<aggregate>.<action>` 格式）
|
||||||
|
|
||||||
|
### 6. 横切关注点对齐清单
|
||||||
|
|
||||||
|
- [ ] 权限装饰器（列出所有端点及对应权限常量）
|
||||||
|
- [ ] 错误码清单（带前缀，每个错误码 → 触发条件 → HTTP 状态码）
|
||||||
|
- [ ] Logger 初始化位置与配置（pino/zap/structlog）
|
||||||
|
- [ ] Metrics 指标清单（指标名 / 类型 / 标签 / 描述）
|
||||||
|
- [ ] Tracer 初始化位置（OTLP endpoint）
|
||||||
|
- [ ] /healthz 检查逻辑
|
||||||
|
- [ ] /readyz 检查逻辑（DB SELECT 1 / Redis PING / Kafka 连接）
|
||||||
|
- [ ] 优雅关闭顺序（HTTP server → DB → Redis → Kafka）
|
||||||
|
|
||||||
|
### 7. 与其他模块的交互点（契约清单）
|
||||||
|
|
||||||
|
| 方向 | 对方服务 | 协议 | 接口/事件 | 用途 |
|
||||||
|
| ------ | -------- | ----- | --------- | ---- |
|
||||||
|
| 调用 | xxx | gRPC | XxxMethod | ... |
|
||||||
|
| 被调用 | xxx | gRPC | YyyMethod | ... |
|
||||||
|
| 发布 | — | Kafka | topic 名 | ... |
|
||||||
|
| 消费 | — | Kafka | topic 名 | ... |
|
||||||
|
|
||||||
|
### 8. 风险与假设
|
||||||
|
|
||||||
|
- 我假设 [某服务] 提供了 [某接口]，如果没提供我的 fallback 是什么？
|
||||||
|
- 我的模块有哪些技术风险？（性能瓶颈、数据一致性、外部依赖）
|
||||||
|
- 有哪些未决的设计决策需要协调 AI 仲裁？
|
||||||
|
```
|
||||||
|
|
||||||

|
||||||
|
|
||||||
|
## 8. 交叉审查规则
|
||||||
|
|
||||||
|
coord 收到全部 7 份设计文档后，执行以下审查：
|
||||||
|
|
||||||
|
### 8.1 接口一致性检查
|
||||||
|
|
||||||
|
```markdown
|
||||||
|
| 服务 A 说 | 服务 B 说 | 是否匹配 |
|
||||||
|
| --------------------------------------------------------- | ---------------------------------------------- | --------- |
|
||||||
|
| ai02 iam: 暴露 getUserInfo(userId) | ai03 teacher-bff: 调用 iam.getUserInfo(userId) | ✅ |
|
||||||
|
| ai03 core-edu: 调用 content.getKnowledgePoints(subjectId) | ai05 content: ??? | ⚠️ 待确认 |
|
||||||
|
```
|
||||||
|
|
||||||
|
### 8.2 全局冲突检查
|
||||||
|
|
||||||
|
| 检查项 | 检查方式 |
|
||||||
|
| -------------------- | ---------------------------------------------------------------------- |
|
||||||
|
| 端口不冲突 | 对照 [full-stack-runbook](../standards/full-stack-runbook.md) 端口矩阵 |
|
||||||
|
| Topic 不重复 | 汇总全部 AI 的 §5 事件设计，去重检查 |
|
||||||
|
| 错误码前缀不重叠 | 汇总全部 AI 的 §6 错误码清单，前缀唯一性检查 |
|
||||||
|
| Proto message 不遗漏 | 检查全部"跨模块交互点"是否在 proto 中有对应定义 |
|
||||||
|
|
||||||
|
### 8.3 黄金模板对齐检查
|
||||||
|
|
||||||
|
| 检查项 | 全部 TS NestJS 服务 |
|
||||||
|
| ----------------------- | ---------------------- |
|
||||||
|
| @RequirePermission 覆盖 | 每个 Controller 方法 |
|
||||||
|
| 错误码前缀 | 用服务名大写前缀 |
|
||||||
|
| /healthz + /readyz | 存在且逻辑正确 |
|
||||||
|
| Zod 输入验证 | Controller 层解析 body |
|
||||||
|
| GlobalErrorFilter | 注册到 AppModule |
|
||||||
|
| Dockerfile 多阶段 | builder + runtime |
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 9. 协作规则
|
||||||
|
|
||||||
|
### 9.1 单仓库并行开发
|
||||||
|
|
||||||
|
当前阶段采用**单仓库直接 push main**模式，不经过 PR：
|
||||||
|
|
||||||
|
- 每个 AI 只能修改自己负责的目录（见 §3.2）
|
||||||
|
- `packages/shared-proto/` 仅 coord 修改，其他 AI 只读
|
||||||
|
- `docs/`、`.trae/`、`infra/`、`.github/` 仅 coord 修改
|
||||||
|
|
||||||
|
### 9.2 唯一冲突文件处理
|
||||||
|
|
||||||
|
`pnpm-lock.yaml` 是唯一可能多 AI 同时修改的文件，冲突时：
|
||||||
|
|
||||||
|
```bash
|
||||||
|
git pull origin main --rebase
|
||||||
|
# 冲突时：
|
||||||
|
git checkout --theirs pnpm-lock.yaml # 取远程版本
|
||||||
|
pnpm install # 重新生成
|
||||||
|
git add pnpm-lock.yaml
|
||||||
|
git rebase --continue
|
||||||
|
```
|
||||||
|
|
||||||
|
### 9.3 提交规范
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# 每个 AI 在自己的服务目录内工作
|
||||||
|
git add services/<service>/...
|
||||||
|
git commit -m "docs(<service>): 模块架构设计文档"
|
||||||
|
|
||||||
|
# 或
|
||||||
|
git commit -m "docs(<service>): 阶段1理解确认书"
|
||||||
|
```
|
||||||
|
|
||||||
|
### 9.4 proto 变更流程
|
||||||
|
|
||||||
|
任何 AI 需要新增/修改 proto：
|
||||||
|
|
||||||
|
1. 在共享协调渠道声明需求（格式：`# proto-change: <描述>`）
|
||||||
|
2. coord 统一修改 `packages/shared-proto/`
|
||||||
|
3. coord 通知受影响 AI 更新设计文档
|
||||||
|

## 10. 审计模板（阶段 1 自检用）
|
||||||
|
|
||||||
|
每个 AI 审计自己负责的已实现服务时，填写下表：
|
||||||
|
|
||||||
|
```markdown
|
||||||
|
## 服务审计表 — [AI标识]
|
||||||
|
|
||||||
|
| 服务 | 权限装饰器 | 错误码前缀 | logger | metrics | tracer | /healthz | /readyz | 优雅关闭 | 测试覆盖率 | Dockerfile |
|
||||||
|
| ---- | ---------- | ---------- | -------- | -------- | -------- | -------- | -------- | -------- | ---------- | ---------- |

## 模块理解确认书 — teacher-bff
|
||||||
|
|
||||||
|
### 1. 我在架构中的位置
|
||||||
|
|
||||||
|
- **层级**：BFF 聚合层（L4）
|
||||||
|
- **上游**：api-gateway（Go/Gin）通过 HTTP 转发请求，注入 `x-user-id` / `x-user-roles` 头
|
||||||
|
- **下游**：iam（3002）、classes（3001）、core-edu（3004）；P3 后扩展 content、data-ana、ai
|
||||||
|
- **通信方式**：
|
||||||
|
- 当前：REST `fetch`（同步）
|
||||||
|
- 目标态（004 §4.1 / pending-features P2）：**gRPC** 调下游业务服务 + **GraphQL Yoga** 对前端暴露 + DataLoader 防 N+1
|
||||||
|
- **端口**：3003（见 [teacher-bff env.ts](../../services/teacher-bff/src/config/env.ts)）
|
||||||
|
|
||||||
|
### 2. 我的限界上下文
|
||||||
|
|
||||||
|
- **聚合职责**：教学场景域（教师 / 教导主任 / 教研组长 共用）的数据聚合、裁剪、协议转换
|
||||||
|
- **业务领域**：跨 D2 教学组织 + D3 教学核心 + D1 身份认证（只读拉取视口/权限）
|
||||||
|
- **我不负责**：
|
||||||
|
- 不持有业务状态（无 DB 写入，无 Outbox）
|
||||||
|
- 不做权限决策（依赖 Gateway JWT 校验 + 下游服务 `@RequirePermission`）
|
||||||
|
- 不直接访问任何业务服务数据库
|
||||||
|
- **复用策略**（004 §5.4）：教导主任 / 教研组长复用 Teacher BFF，通过视口差异化（L1 导航扩展管理菜单，L4 DataScope 扩大到年级）
|
||||||
|
|
||||||
|
### 3. 我与外部的契约
|
||||||
|
|
||||||
|
- **消费的 proto message**：
|
||||||
|
- `iam.v1.IamService`：GetUserInfo / getEffectivePermissions（视口 + DataScope）
|
||||||
|
- `classes.v1.ClassService`：ListClasses / GetClass
|
||||||
|
- `core_edu.v1.ExamService / HomeworkService / GradeService`：全部 RPC
|
||||||
|
- **暴露的 API**（当前 REST，目标 GraphQL）：
|
||||||
|
- `GET /teacher/dashboard` — 聚合 IAM 用户信息 + classes 列表
|
||||||
|
- `GET /teacher/viewports` — 拉取 IAM 视口配置（L1 导航）
|
||||||
|
- `GET /teacher/classes/:classId/exams` — 聚合 core-edu 考试列表
|
||||||
|
- `GET /teacher/classes/:classId/homework` — 聚合 core-edu 作业列表
|
||||||
|
- `GET /teacher/exams/:examId/grades` — 聚合 core-edu 成绩列表
|
||||||
|
- **错误码前缀**：BFF 自身错误用 `BAD_GATEWAY`（下游不可达）；业务错误透传下游 `CORE_EDU_*` / `IAM_*` / `CLASSES_*`
|
||||||
|
- **缓存**：聚合结果 Redis 短缓存 5-30s（004 §6.3，当前未实现）
|
||||||
|
|
||||||
|
### 4. 我的技术栈
|
||||||
|
|
||||||
|
- 语言：TypeScript 5.5+（ESM 模式，相对 import 带 `.js` 后缀）
|
||||||
|
- 框架：NestJS 10
|
||||||
|
- 下游通信：当前 `fetch`（REST）→ 目标 `@grpc/grpc-js` + `@bufbuild/protobuf`
|
||||||
|
- 对前端：目标 GraphQL Yoga + DataLoader
|
||||||
|
- 缓存：Redis（待引入）
|
||||||
|
- 可观测：pino logger + prom-client metrics + OpenTelemetry tracer（已具备 [tracer.ts](../../services/teacher-bff/src/shared/observability/tracer.ts)）
|
||||||
|
|
||||||
|
### 5. 我的阶段归属
|
||||||
|
|
||||||
|
- **P2 身份**：教师登录 → 获取 JWT → 访问 teacher-portal → 侧边栏按 viewports.L1 渲染 → 空白 Dashboard
|
||||||
|
- **P3 扩展**：考试/作业/成绩的 GraphQL 查询与 mutation
|
||||||
|
- **依赖上游**：P1 黄金模板 classes、P2 iam（getEffectivePermissions + 视口）
|
||||||
|
|
||||||
|
### 6. 我需要对齐的黄金模板项（对照 classes 服务）
|
||||||
|
|
||||||
|
- [ ] 权限装饰器 `@RequirePermission`（**BFF 不做权限决策**，当前无；目标态：BFF 不加 Guard，仅校验 `x-user-id` 存在）
|
||||||
|
- [x] 错误处理：[GlobalErrorFilter](../../services/teacher-bff/src/shared/errors/global-error.filter.ts) + ApplicationError 层次
|
||||||
|
- [x] logger / metrics / tracer 三支柱（已具备）
|
||||||
|
- [x] `/healthz` 健康检查（HealthModule 已注册）
|
||||||
|
- [ ] `/readyz`（当前 HealthController 仅 liveness，无下游就绪探针）
|
||||||
|
- [x] 优雅关闭 SIGTERM（main.ts 已处理）
|
||||||
|
- [ ] 测试覆盖率 ≥ 80%（**当前 0%**，无测试文件）
|
||||||
|
- [ ] Dockerfile 多阶段构建（需核对）
|
||||||
|
- [ ] Zod 输入验证（当前 Controller 直接透传 unknown，**未做 Zod 校验**）
|
||||||
|
- [x] GlobalErrorFilter 统一兜底
|
||||||

## §10 服务审计表 — ai03
|
||||||
|
|

|
||||||
|
| core-edu | ✅ `@RequirePermission(EXAM_*)` 全覆盖 | ✅ `CORE_EDU_*` | ✅ pino | ✅ prom-client | ✅ OTel | ✅ | ❌ | ✅ | 0% ❌ | 待核对 |
|
||||||
|
|
||||||
|
### 审计发现的关键差距（P3 阶段 2 设计需解决）
|
||||||
|
|
||||||
|
**teacher-bff**：
|
||||||
|
|
||||||
|
1. ❌ 通信方式：当前 REST `fetch`，目标 gRPC + GraphQL（P2 退出标准要求 GraphQL Yoga + DataLoader）
|
||||||
|
2. ❌ 无 Redis 聚合缓存（004 §6.3 要求 5-30s 短缓存）
|
||||||
|
3. ❌ 无 DataLoader（防 N+1，pending-features P2 明确要求）
|
||||||
|
4. ❌ 无 `/readyz` 下游就绪探针
|
||||||
|
5. ⚠️ env 配置用 `IamServiceUrl`/`ClassesServiceUrl`（REST URL），转 gRPC 后需改为 gRPC target
|
||||||
|
6. ⚠️ 无 Zod 输入验证
|
||||||
|
7. ⚠️ 无测试
|
||||||
|
|
||||||
|
**core-edu**：
|
||||||
|
|
||||||
|
1. ❌ 考试生命周期状态机缺失（当前仅 `draft` 初值，无 `published → in_progress → grading → graded → archived` 转换与校验）
|
||||||
|
2. ❌ 作业状态机不完整（仅 `assigned → submitted`，缺 `graded`；pending-features 要求 `HomeworkGraded` 事件）
|
||||||
|
3. ❌ 成绩录入无业务校验（不校验 exam/homework 是否存在、score 是否在 totalScore 范围内、是否重复录入）
|
||||||
|
4. ❌ 作业提交高并发优化缺失（004 §9.2 要求 Redis 分布式锁 + 排队）
|
||||||
|
5. ❌ 无 `grade.updated` / `homework.graded` 事件触发点（proto 已定义，service 未实现）
|
||||||
|
6. ❌ 未消费 IAM `user.created` 事件（初始化教师默认关联）
|
||||||
|
7. ⚠️ Drizzle `db` 直接导出 vs classes 的 `getDb()` 函数式 — **不一致**，建议统一为 `getDb()`
|
||||||
|
8. ⚠️ [kafka.ts](../../services/core-edu/src/config/kafka.ts) 用 `console.log`/`console.warn`，应改用结构化 logger
|
||||||
|
9. ⚠️ classes 模块在 core-edu 仅有 `classes.module.ts` 占位，**P3 待合并**（classes 服务代码迁入 + 删除独立 services/classes）
|
||||||
|
10. ⚠️ 入口仍为 REST，proto gRPC 契约已定义但未接入 `@grpc/grpc-js` + buf generate 代码
|
||||||
|
11. ❌ 无 Zod 输入验证（Controller 直接接收 `body: CreateExamInput`，未走 zod schema）
|
||||||
|
12. ❌ 无测试
|
||||||
|
|
||||||
|
### 跨模块契约对齐待确认项（提请 coord 交叉审查）
|
||||||
|
|
||||||
|
| 待确认项 | 我方期望 | 对方模块 | 状态 |
|
||||||
|
| ---------------------------------------------- | ----------------------------------------------------------------------------------- | --------------------------------- | ---------------------------------------------------------------------------------------------------- |
|
||||||
|
| iam `getEffectivePermissions(userId)` 返回结构 | `{permissions, viewports, dataScope}` | iam（ai02） | ⚠️ 当前 teacher-bff 调 `/iam/viewports` 与 `/iam/me`，未定义此聚合 API 的 proto |
|
||||||
|
| iam `user.created` 事件 topic | `edu.identity.user.created` | iam（ai02） | ⚠️ 004 §7.2 定义，但 core-edu 未消费，需确认 iam 是否发布 |
|
||||||
|
| core-edu 端口 3004 | 不冲突 | 全局端口矩阵 | 待 coord 核对 |
|
||||||
|
| Kafka topic 命名 | `edu.exam.events` / `edu.homework.events` / `edu.grade.events` / `edu.class.events` | 004 §7.2 用 `edu.teaching.*` 前缀 | ⚠️ **不一致**：004 文档用 `edu.teaching.exam.published`，代码用 `edu.exam.events`，需 coord 仲裁统一 |
|
||||||
|
| data-ana 消费 core-edu 事件 | 消费 `exam.created` / `homework.submitted` / `grade.recorded` | data-ana（ai06） | 待 ai06 确认消费契约 |
|
||||||
|
| msg 消费 core-edu 事件 | 消费 `exam.created` / `homework.assigned` / `grade.recorded` 触发通知 | msg（ai05） | 待 ai05 确认消费契约 |
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 下一步（阶段 2 入口）
|
||||||
|
|
||||||
|
待 coord 审核本确认书通过后，ai03 进入阶段 2，按 [ai-allocation.md §5 ai03 设计重点](./ai-allocation.md#ai03--教学场景域) 产出两份模块架构设计文档：
|
||||||
|
|
||||||
|
1. **teacher-bff 模块架构设计**：GraphQL schema（Query/Mutation 按场景域组织）、DataLoader 批量去重、并行 gRPC 编排、聚合缓存 TTL、教师角色差异化视口推导
|
||||||
|
2. **core-edu 模块架构设计**：classes 黄金模板对齐、考试生命周期状态机、Outbox 事件定义、成绩计算配置化、作业提交高并发（Redis 锁 + 排队）、排课/考勤数据模型
|
||||||
|
|
||||||
|
阶段 2 设计需先解决上述 12 项差距与 6 项跨模块契约对齐。

## 模块理解确认书 — content
|
||||||
|
|
||||||
|
### 1. 我在架构中的位置
|
||||||
|
|
||||||
|
- **层级**：业务微服务层（L5），DDD 限界上下文
|
||||||
|
- **业务领域**：D4 内容资源领域（004 §1.1b）
|
||||||
|
- **上游**（谁调用我）：
|
||||||
|
- teacher-bff（3003）：教学场景聚合，教师查教材/知识点/题库
|
||||||
|
- student-bff（学习场景，P3 起）：学生查学习路径、知识点前置
|
||||||
|
- ai（Python，P5）：gRPC 查询知识点/题库用于 AI 出题（004 §4.1 `AI -.gRPC.-> Content`，§9.3 AI 辅助出题流程）
|
||||||
|
- **下游**（我调用谁）：
|
||||||
|
- MySQL（写模型主库，独占）
|
||||||
|
- Neo4j（知识图谱，前置依赖图）
|
||||||
|
- Elasticsearch（题库全文检索，P4 后续补充，当前未实现）
|
||||||
|
- **通信方式**：
|
||||||
|
- 当前：HTTP REST（Controller，无 gRPC controller）
|
||||||
|
- 目标态（004 §4.1 / pending-features P4）：gRPC 暴露 `TextbookService` + `KnowledgeGraphService`
|
||||||
|
- Kafka：消费 core-edu 教学内容变更通知（004 §4.1 `CoreEdu -.事件.-> Content`）；发布 `edu.content.question.published`（004 §7.2）
|
||||||
|
- **端口**：3005（见 [content env.ts](../../services/content/src/config/env.ts)）
|
||||||
|
|
||||||
|
### 2. 我的限界上下文
|
||||||
|
|
||||||
|
- **聚合职责**：管理 Textbook（教材）、Chapter（章节）、KnowledgePoint（知识点）、Question（题库）四个聚合
|
||||||
|
- **我的数据属于**：D4 内容资源领域
|
||||||
|
- **我不负责**：
|
||||||
|
- 不负责学情分析（D6，由 data-ana 承载）
|
||||||
|
- 不负责考试/作业/成绩（D3，由 core-edu 承载）
|
||||||
|
- 不负责通知分发（D5，由 msg 承载）
|
||||||
|
- 不直接访问 core-edu / iam / msg 的数据库
|
||||||
|
- **现有骨架领域模块**（4 个，见 [content/src](../../services/content/src)）：
|
||||||
|
- `textbooks/`：教材 CRUD（5 端点）
|
||||||
|
- `chapters/`：章节 CRUD（5 端点，按 textbook 查询）
|
||||||
|
- `knowledge-points/`：知识点 CRUD + Neo4j 知识图谱（7 端点，含前置链路查询/添加）
|
||||||
|
- `questions/`：题库 CRUD（5 端点，4 种题型校验）
|
||||||
|
|
||||||
|
### 3. 我与外部的契约
|
||||||
|
|
||||||
|
- **消费的 proto message**（从 shared-proto）：
|
||||||
|
- 无直接消费其他服务 proto；通过 Kafka 事件接收 core-edu 教学内容变更（事件契约见 `events.proto`）
|
||||||
|
- **暴露的契约**（见 [content.proto](../../packages/shared-proto/proto/content.proto)，包名 `next_edu_cloud.content.v1`）：
|
||||||
|
- `TextbookService`：CreateTextbook / GetTextbook / ListTextbooks
|
||||||
|
- `KnowledgeGraphService`：GetPrerequisites / GetLearningPath
|
||||||
|
- **当前实现均为 REST，gRPC controller 未实现**（proto 已定义待迁移）
|
||||||
|
- **事件契约**：
|
||||||
|
- 发布：`edu.content.question.published`（题库新增/发布，消费者 AI、ES，见 004 §7.2）
|
||||||
|
- 消费：core-edu 教学内容变更事件（004 §4.1，具体 topic 待 core-edu ai03 设计确认）
|
||||||
|
- **错误码前缀**：`CONTENT_*`（CONTENT_VALIDATION_ERROR / NOT_FOUND / PERMISSION_DENIED / CONFLICT / BUSINESS_ERROR / DATABASE_ERROR / INTERNAL_ERROR，见 [application-error.ts](../../services/content/src/shared/errors/application-error.ts)）
|
||||||
|
- **权限点**（16 个，见 [permission.guard.ts](../../services/content/src/middleware/permission.guard.ts)）：
|
||||||
|
- `CONTENT_TEXTBOOK_{CREATE,READ,UPDATE,DELETE}`
|
||||||
|
- `CONTENT_CHAPTER_{CREATE,READ,UPDATE,DELETE}`
|
||||||
|
- `CONTENT_QUESTION_{CREATE,READ,UPDATE,DELETE}`
|
||||||
|
- `CONTENT_KNOWLEDGE_POINT_{CREATE,READ,UPDATE,DELETE}`
|
||||||
|
|
||||||
|
### 4. 我的技术栈
|
||||||
|
|
||||||
|
- 语言：TypeScript 5.6（ESM 模式，相对 import 带 `.js` 后缀）
|
||||||
|
- 框架：NestJS 10
|
||||||
|
- ORM：Drizzle ORM 0.31 + mysql2 3.11
|
||||||
|
- 知识图谱：neo4j-driver 5.23（PREREQUISITE_OF 关系，Cypher 查询深度 1..5）
|
||||||
|
- 全文检索：Elasticsearch（**待引入**，env.ts 预留 ES_URL 但 package.json 未装 @elastic/elasticsearch）
|
||||||
|
- 可观测：pino logger + prom-client metrics + OpenTelemetry tracer（三支柱已具备）
|
||||||
|
- 消息总线：Kafka（**待引入**，pending-features P4 未明确要求 content 发事件，但 004 §7.2 列了 `edu.content.question.published`）
|
||||||
|
|
||||||
|
### 5. 我的阶段归属
|
||||||
|
|
||||||
|
- **P4 内容分析阶段**（pending-features §P4）：
|
||||||
|
- 教材/章节/知识点 CRUD（仅 CRUD，不实现检索）+ 知识图谱查询（Neo4j）+ 题库 CRUD（不实现检索）
|
||||||
|
- MySQL schema：textbooks / chapters / knowledge_points / questions
|
||||||
|
- Neo4j 数据：知识点前置依赖图（从 MySQL 同步）
|
||||||
|
- CDC 链路：Debezium 监听 MySQL binlog → Kafka → data-ana 消费写 ClickHouse
|
||||||
|
- **退出标准**：教师查看知识图谱前置依赖（Neo4j 秒级返回）→ 学生查看学情诊断（ClickHouse 宽表 5s 内返回）→ CDC 链路延迟 < 5s
|
||||||
|
- **依赖上游**：P1 黄金模板 classes（横切关注点对齐）、P3 core-edu（教学内容变更事件，待 ai03 设计确认 topic）
|
||||||
|
|
||||||
|
### 6. 我需要对齐的黄金模板项（对照 classes 服务）
|
||||||
|
|
||||||
|
- [x] 权限装饰器 `@RequirePermission`（16 个 CONTENT_* 权限点，全部 Controller 方法已覆盖）
|
||||||
|
- [x] 错误码前缀统一（`CONTENT_*`）
|
||||||
|
- [x] logger / metrics / tracer 三支柱（已具备）
|
||||||
|
- [x] `/healthz` 健康检查（HealthModule 已注册）
|
||||||
|
- [⚠️] `/readyz`（**仅检查 DB `SELECT 1`，未检查 Neo4j 连通性**，Neo4j 故障时仍返回 ok）
|
||||||
|
- [x] 优雅关闭 SIGTERM（main.ts 已处理：closeNeo4j → closeDb → shutdownTracer）
|
||||||
|
- [ ] 测试覆盖率 ≥ 80%（**当前 0%**，无测试文件）
|
||||||
|
- [x] Dockerfile 多阶段构建（已具备）
|
||||||
|
- [⚠️] Zod 输入验证（questions 用 service 层手动 if 校验抛 ValidationError，**非 Controller 层 schema.parse**）
|
||||||
|
- [x] GlobalErrorFilter 统一兜底
|
||||||
|
|
||||||
|
### 7. 现有骨架差距与待决策（提请 coord 仲裁）
|
||||||
|
|
||||||
|
| # | 差距 | 影响 | 提请决策 |
|
||||||
|
| --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------- | ----------------------------------------------------------------------------- |
|
||||||
|
| C1 | **ES 完全未实现**：env.ts 预留 ES_URL 但无 @elastic/elasticsearch 依赖、无 config/elasticsearch.ts、无 service 调用 | P4 退出标准要求题库检索，pending-features 注明"P4 仅 CRUD，P5 引入 ES" | 确认 content 的 ES 检索归属 P4 还是 P5（004 §2.2 列 ES 使用者为 Content、AI） |
|
||||||
|
| C2 | **无 Outbox / Kafka**：骨架无 shared/outbox/，无 Kafka producer/consumer | 004 §7.2 列 `edu.content.question.published` 事件需发布 | 确认 content 是否需 Outbox（iam 无 Outbox，core-edu 有） |
|
||||||
|
| C3 | **README 与实现脱节**：README 声称 `TextbooksService.createKnowledgeGraph` 和 `getPrerequisites`，源码中 createKnowledgeGraph 不存在，getPrerequisites 在 KnowledgePointsService | 文档误导 | 阶段 2 设计需同步修正 README |
|
||||||
|
| C4 | **gRPC 未实现**：proto 定义了 TextbookService/KnowledgeGraphService，但无 gRPC controller | pending-features P4 未强制 gRPC，004 §4.1 目标态 gRPC | 确认 P4 是否启用 gRPC（ai03 提请统一决策） |
|
||||||
|
| C5 | **schema 定义分散**：textbooks.schema.ts 定义 3 张表（textbooks/chapters/knowledgePoints），chapters/knowledge-points schema 仅 re-export；questions.schema.ts 独立 | 维护成本 | 阶段 2 设计统一 schema 归属 |
|
||||||
|
| C6 | **DB 连接模式与 iam 不一致**：content 用模块级 `const db`，iam 用 `getDb()` 函数式懒加载 | 测试 mock 困难 | coord 已在 known-issues 记录"db 常量导出对齐黄金模板"，需确认统一方向 |
|
||||||
|
| C7 | **表时间戳不统一**：textbooks/questions 有 created_at+updated_at，chapters/knowledge_points 无时间戳 | 审计追踪缺失 | 阶段 2 设计补齐 |
|
||||||
|
| C8 | **无外键约束**：questions.knowledge_point_id → knowledge_points.id 等无 Drizzle 外键 | 引用完整性靠应用层 | 阶段 2 设计评估是否加外键 |
|
||||||
|
| C9 | **addPrerequisite 降级策略不一致**：safeCreateNode 非阻塞（Neo4j 失败仅 warn），addPrerequisite 在 Neo4j 不可用时抛 InternalError | 行为不一致 | 阶段 2 设计统一降级策略 |
|
||||||
|
| C10 | **proto 包名**：实际 `next_edu_cloud.content.v1`，project_rules §5 规定 `edu.content.v1` | 命名规范不一致 | **coord 仲裁**（ai03 已提请） |

|
||||||
|
- **我不负责**：
|
||||||
|
- 不负责 WebSocket 长连接管理（由 push-gateway 承载）

||||||
|
|
||||||

|
|
||||||
|
- **消费的 proto message**（从 shared-proto）：
|
||||||
|
- 消费 `events.proto` 的事件 message（ClassEvent/ExamEvent/HomeworkEvent/GradeEvent）
|
||||||
|

|
||||||
|
- `edu.teaching.exam.published`（core-edu 发，msg 推送考试通知给学生）
|
||||||
|
- `edu.teaching.assignment.submitted`（core-edu 发，msg 通知教师）
|
||||||
|
- `edu.teaching.grade.recorded`（core-edu 发，msg 通知学生）
|
||||||
|
- `edu.insight.mastery.updated`（data-ana 发，msg 触发预警）
|
||||||
|
- 发布：无明确（pending-features 未要求 msg 发事件）
|
||||||
|
- **错误码前缀**：`MSG_*`（MSG_VALIDATION_ERROR / NOT_FOUND / PERMISSION_DENIED / CONFLICT / BUSINESS_ERROR / DATABASE_ERROR / INTERNAL_ERROR，见 [application-error.ts](../../services/msg/src/shared/errors/application-error.ts)）
|
||||||
|
- **权限点**（3 个，见 [permission.guard.ts](../../services/msg/src/middleware/permission.guard.ts)）：
|
||||||
|
- `MSG_NOTIFICATION_SEND`、`MSG_NOTIFICATION_READ`、`MSG_NOTIFICATION_MANAGE`
|
||||||
|
|
||||||
|
### 4. 我的技术栈
|
||||||
|
|
||||||
|
- 语言：TypeScript 5.6（ESM 模式）
|
||||||
|
- 框架：NestJS 10
|
||||||
|
- ORM：Drizzle ORM 0.31 + mysql2 3.11
|
||||||
|
- 全文检索：@elastic/elasticsearch 8.15（已实现 safeIndex/safeSearch，**无 mapping 定义**，依赖动态 mapping）
|
||||||
|
- 消息总线：kafkajs 2.2（**已装依赖但无 consumer/producer 代码**，env.ts 有 KAFKA_BROKERS 默认值）
|
||||||
|
- 推送：fetch POST 到 push-gateway `/internal/push`（降级模式，PUSH_GATEWAY_URL 未配置或失败时跳过）
|
||||||
|
- 幂等去重：Redis（**env.ts 预留 REDIS_URL 但无 redis 客户端依赖**，pending-features P5 要求 event_id 去重）
|
||||||
|
- 可观测：pino + prom-client + OpenTelemetry（三支柱已具备）
|
||||||
|
|
||||||
|
### 5. 我的阶段归属
|
||||||
|
|
||||||
|
- **P5 沟通与 AI 阶段**（pending-features §P5）：
|
||||||
|
- 会话/消息 CRUD + 调 Push Gateway 推送 + 通知偏好
|
||||||
|
- 多渠道（站内/SMS/邮件/微信），沿用旧项目 dispatcher 模式
|
||||||
|
- Elasticsearch 题库全文检索（从 MySQL 同步）
|
||||||
|
- **退出标准**：教师发广播通知 → 全在线学生实时收到（Push Gateway）→ AI 辅助出题流式返回 → 题库全文检索 < 200ms
|
||||||
|
- **依赖上游**：P1 黄金模板 classes、P3 core-edu（事件来源）、P5 push-gateway（推送通道，ai01 设计）、P5 ai（无直接依赖）
|
||||||
|
|
||||||
|
### 6. 我需要对齐的黄金模板项（对照 classes 服务）
|
||||||
|
|
||||||
|
- [x] 权限装饰器 `@RequirePermission`（3 个 MSG_* 权限点，全部 Controller 方法已覆盖）
|
||||||
|
- [x] 错误码前缀统一（`MSG_*`）
|
||||||
|
- [x] logger / metrics / tracer 三支柱（已具备）
|
||||||
|
- [x] `/healthz` 健康检查（HealthModule 已注册）
|
||||||
|
- [⚠️] `/readyz`（**仅检查 DB `SELECT 1`，未检查 ES 连通性**，ES 故障时仍返回 ok）
|
||||||
|
- [x] 优雅关闭 SIGTERM（main.ts 已处理：app.close → closeEs → closeDb → shutdownTracer）
|
||||||
|
- [ ] 测试覆盖率 ≥ 80%（**当前 0%**，无测试文件）
|
||||||
|
- [x] Dockerfile 多阶段构建（已具备）
|
||||||
|
- [⚠️] Zod 输入验证（Controller 用 `schema.parse(body)`，**但 ZodError 未在 GlobalErrorFilter 特殊处理，走默认 500 而非 400**）
|
||||||
|
- [x] GlobalErrorFilter 统一兜底
|
||||||
|
|
||||||
|
### 7. 现有骨架差距与待决策（提请 coord 仲裁）
|
||||||
|
|
||||||
|
| # | 差距 | 影响 | 提请决策 |
|
||||||
|
| --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------- |
|
||||||
|
| M1 | **Kafka 消费未实现**：装了 kafkajs 但无 consumer 代码，无 shared/kafka/ 目录 | 004 §7.3 列 msg 消费 5 类事件（ExamPublished/HomeworkGraded/GradeRecorded/UserRegistered/MasteryUpdated） | 阶段 2 设计需补 Kafka consumer + 幂等去重 |
|
||||||
|
| M2 | **无 Outbox**：骨架无 shared/outbox/ | msg 作为通知中心，发送通知后可能需发事件（如 NotificationSent） | 确认 msg 是否需 Outbox（iam 无，core-edu 有） |
|
||||||
|
| M3 | **ES 无 mapping 定义**：依赖动态 mapping，索引名 "notifications" 硬编码在 service | 检索质量不稳定，索引管理缺失 | 阶段 2 设计补 mapping + ensureIndex |
|
||||||
|
| M4 | **无独立 repository**：notifications.service.ts 直接用 db，无 repository 抽象 | 与黄金模板分层不一致（iam 有 repository） | 阶段 2 设计补 repository 层 |
|
||||||
|
| M5 | **Redis 未引入**：env.ts 预留 REDIS_URL 但无 redis 客户端依赖 | pending-features P5 要求 event_id 去重（Redis SETNX 或 DB 唯一索引） | 阶段 2 设计决策：Redis SETNX vs DB 唯一索引 |
|
||||||
|
| M6 | **createBatch 无事务/无批量优化**：for 循环串行调 send，无批量 INSERT | 性能瓶颈（广播场景） | 阶段 2 设计改为批量 INSERT |
|
||||||
|
| M7 | **NotificationsModule 缺 exports**：notifications.module.ts 无 `exports: [NotificationsService]` | 未来 BFF 注入受阻 | 阶段 2 设计补 exports |
|
||||||
|
| M8 | **ZodError 未特殊处理**：GlobalErrorFilter 未识别 ZodError，走默认 500 | 输入校验错误返回码错误（500 而非 400） | 阶段 2 设计 GlobalErrorFilter 补 ZodError 分支（iam 已有可参考） |
|
||||||
|
| M9 | **gRPC 未实现**：proto 定义了 NotificationService，但无 gRPC controller | pending-features P5 未强制 gRPC | 确认 P5 是否启用 gRPC（ai03 提请统一决策） |
|
||||||
|
| M10 | **README 与实现脱节**：README API 表标 `POST /notifications/:id/read`，实际是 PUT；漏 batch/user/:userId/user/:userId/page 端点；声称"消费 Kafka 事件"但无代码 | 文档误导 | 阶段 2 设计同步修正 README |
|
||||||
|
| M11 | **main.ts 与 LifecycleService 重复关闭资源**：两者都调 closeDb/closeEs | 重复关闭可能报错（虽有 try-catch） | 阶段 2 设计统一关闭逻辑到 LifecycleService |
|
||||||
|
| M12 | **proto 包名**：实际 `next_edu_cloud.msg.v1`，project_rules §5 规定 `edu.msg.v1` | 命名规范不一致 | **coord 仲裁**（ai03 已提请） |
|
||||||

## 四、跨模块契约对齐提请（coord 交叉审查）
|
||||||
|
|
||||||
|
### 4.1 接口一致性检查
|
||||||
|
|
||||||
|
| 本服务声明 | 对方服务声明 | 是否匹配 | 备注 |
|
||||||
|
| --------------------------------------------------------- | ------------------------------------------------- | --------- | ------------------------------------------------------------------------------------------------ |
|

|
||||||
|
| ai05 content: 发布 `edu.content.question.published` | ai06 ai: 消费题库事件（004 §7.2 消费者 AI） | ⚠️ 待确认 | ai06 设计需确认是否消费 |
|
||||||
|
| ai05 msg: 消费 `edu.teaching.exam.published` | ai03 core-edu: 发布考试事件 | ⚠️ 待确认 | ai03 提请 topic 命名统一（004 `edu.teaching.exam.published` vs core-edu 代码 `edu.exam.events`） |
|
||||||
|
| ai05 msg: 消费 `edu.identity.user.created` | ai02 iam: 发布用户创建事件 | ⚠️ 待确认 | ai02 设计需确认 topic |
|
||||||
|
| ai05 msg: 调 push-gateway `/internal/push` | ai01 push-gateway: 暴露推送端点 | ✅ 已实现 | msg 当前用 fetch POST，push-gateway 已有 /internal/push 端点 |
|
||||||
|
|
||||||
|
### 4.2 全局冲突检查
|
||||||
|
|
||||||
|
| 检查项 | 检查结果 | 备注 |
|
||||||
|
| -------------------- | ----------------------------- | ------------------------------------------------------------------------------------------------------------------------------- |
|
||||||
|
| 端口不冲突 | ✅ content 3005、msg 3007 | 与 iam(3002)/classes(3001)/teacher-bff(3003)/core-edu(3004)/data-ana(3006)/ai(3008) 不冲突 |
|
||||||
|
| Topic 不重复 | ⚠️ 待汇总 | content 发布 `edu.content.question.published`；msg 仅消费不发布 |
|
||||||
|
| 错误码前缀不重叠 | ✅ `CONTENT_*` / `MSG_*` 唯一 | 与 iam `IAM_*` / core-edu `CORE_EDU_*` 不重叠 |
|
||||||
|
| Proto message 不遗漏 | ⚠️ 待确认 | events.proto 无 NotificationEvent，若 msg 发事件需补充；content.proto 缺 Update/Delete/分页（对比 classes.proto 有 page_token） |
|
||||||
|
| proto 包名规范 | ⚠️ 不一致 | 实际 `next_edu_cloud.<domain>.v1`，规则要求 `edu.<domain>.v1`，**提请 coord 仲裁**（ai03 已提请） |
|
||||||
|
|
||||||
|
### 4.3 待 coord 仲裁的决策项
|
||||||
|
|
||||||
|
1. **proto 包名统一**：`next_edu_cloud.*` vs `edu.*`（影响全部 proto，需 coord 决策）
|
||||||
|
2. **gRPC 启用时机**：P4/P5 是否启用 gRPC controller，还是继续 REST（影响 content/msg/iam/core-edu 全部服务）
|
||||||
|
3. **content ES 检索归属**：P4（pending-features 注明"P4 仅 CRUD，P5 引入 ES"）vs 004 §2.2（列 ES 使用者 Content、AI）—— 需明确 content 何时引入 ES
|
||||||
|
4. **content Outbox**：是否需要（004 §7.2 列 content 发事件，但 pending-features P4 未要求）
|
||||||
|
5. **msg Outbox**：是否需要（msg 仅消费事件触发通知，是否需发 NotificationSent 事件）
|
||||||
|
6. **msg Redis 引入**：env.ts 预留 REDIS_URL 但无依赖，幂等去重用 Redis SETNX 还是 DB 唯一索引
|
||||||
|
7. **events.proto 补充**：若 msg 发事件需追加 NotificationEvent message
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 五、下一步
|
||||||
|
|
||||||
|
1. **等待 coord 审核本确认书**（§4 跨模块契约对齐 + §4.3 仲裁项）
|
||||||
|
2. coord 放行后进入**阶段 2：模块架构设计文档**，按 ai-allocation.md §7 模板产出：
|
||||||
|
- content 模块架构设计文档（含 Neo4j 图模型、ES 索引 mapping、题库 CRUD API、与 ai 的 gRPC 接口、教材/章节结构树）
|
||||||
|
- msg 模块架构设计文档（含通知渠道抽象策略模式、ES 降级查询、Kafka 消费幂等、push-gateway 推送协议、通知模板、已读/未读状态管理）
|
||||||
|
3. 阶段 2 设计完成后同步更新 README（修正 §C3/M10 文档脱节问题）

## 模块理解确认书 — data-ana
|
||||||
|
|
||||||
|
### 1. 我在架构中的位置
|
||||||
|
|
||||||
|
- **层级**：业务微服务层（L5），属 **D6 智能洞察领域**（004 §1.1b）
|
||||||
|
- **上游**：
|
||||||
|
- api-gateway 直接 HTTP 代理 `/api/v1/analytics/*` → data-ana:3006（见 [api-gateway main.go:142-148](../../services/api-gateway/main.go)）
|
||||||
|
- teacher-bff / student-bff 聚合查询（004 §4.1：BFF → 业务服务 gRPC；当前为 REST）
|
||||||
|
- **下游**：
|
||||||
|
- ClickHouse（独占读模型，宽表 `student_dashboard_view` / `student_errors`）
|
||||||
|
- Kafka（消费 Debezium CDC 事件 + 待发布 `edu.insight.mastery.updated` 领域事件）
|
||||||
|
- **通信方式**：
|
||||||
|
- 入口：当前 REST（`/analytics/class/{id}/performance`、`/analytics/student/{id}/weakness`、`/analytics/student/{id}/errorbook`）；目标态（004 §4.1 + analytics.proto）转 **gRPC** 暴露 `AnalyticsService`
|
||||||
|
- 出口：Kafka 消费（CDC + 领域事件订阅）；Kafka 发布（`edu.insight.mastery.updated`，**未实现**）
|
||||||
|
- **端口**：3006（见 [data-ana config.py:7](../../services/data-ana/src/data_ana/config.py) + [api-gateway config.go:55](../../services/api-gateway/internal/config/config.go)）
|
||||||
|
|
||||||
|
### 2. 我的限界上下文
|
||||||
|
|
||||||
|
- **聚合职责**：学情分析读模型构建 + 查询服务，承载 **D6 智能洞察领域**的"分析/诊断"子域
|
||||||
|
- **聚合根 / 实体**：
|
||||||
|
- `StudentDashboard`（学生学情宽表视图，ClickHouse 物化）
|
||||||
|
- `StudentErrorBook`（学生错题本，ClickHouse 物化）
|
||||||
|
- `ClassPerformance`（班级成绩聚合，ClickHouse 即时聚合）
|
||||||
|
- `MasterySnapshot`（知识点掌握度快照，**待实现**）
|
||||||
|
- **业务领域**：D6 智能洞察（与 ai 服务共享领域，ai 偏"生成"，data-ana 偏"分析"）
|
||||||
|
- **我不负责**：
|
||||||
|
- 不负责写模型（成绩由 core-edu 写 MySQL，data-ana 只消费 CDC）
|
||||||
|
- 不负责题库内容（→ content 服务）
|
||||||
|
- 不负责通知投递（→ msg 服务消费 data-ana 发布的 `mastery.updated` 事件触发预警）
|
||||||
|
- 不负责 AI 推理（→ ai 服务，ai 通过 gRPC 反向查询 data-ana 学情数据）
|
||||||
|
- **数据自治**：独占 `edu_analytics` ClickHouse 数据库（不与 MySQL 写模型混用）
|
||||||
|
|
||||||
|
### 3. 我与外部的契约
|
||||||
|
|
||||||
|
#### 消费的 proto message
|
||||||
|
|
||||||
|
| 来源 | message | 用途 |
|
||||||
|
| --------------- | ------------------------------- | ---------------------------------------------- |
|
||||||
|
| events.proto | `GradeEvent` | 消费 core-edu 成绩写入事件 → 更新学情宽表 |
|
||||||
|
| events.proto | `ExamEvent` | 消费考试事件 → 缓存 exam_id→class_id 映射 |
|
||||||
|
| events.proto | `HomeworkEvent` | 消费作业提交/批改事件 → 更新学情（**待实现**） |
|
||||||
|
| events.proto | `ClassEvent` | 消费班级变更事件 → 同步班级维度（**待实现**） |
|
||||||
|
| analytics.proto | `GetClassPerformanceRequest` 等 | gRPC 暴露契约（**待实现 gRPC server**） |
|
||||||
|
|
||||||
|
> **CDC 直连 vs 领域事件双通道**：当前实现走 Debezium CDC（直接监听 MySQL binlog），不依赖 core-edu 的 Outbox。这是 ADR-008 的设计决策（CDC 解耦 Outbox Relay，减少业务侵入）。Outbox 领域事件（events.proto）作为业务语义更清晰的补充通道，待 P4 后期评估是否双消费。
|
||||||
|
|
||||||
|
#### 暴露的 API / 事件
|
||||||
|
|
||||||
|
**HTTP 端点**（当前实现，见 [main.py](../../services/data-ana/src/data_ana/main.py)）：
|
||||||
|
|
||||||
|
| method | path | 说明 |
|
||||||
|
| ------ | ------------------------------------------- | -------------------------------------- |
|
||||||
|
| GET | `/healthz` | liveness |
|
||||||
|
| GET | `/readyz` | readiness（含 ClickHouse + CDC 状态） |
|
||||||
|
| GET | `/metrics` | Prometheus 指标 |
|
||||||
|
| GET | `/analytics/class/{class_id}/performance` | 班级成绩分析（平均分/及格率/参考人数） |
|
||||||
|
| GET | `/analytics/student/{student_id}/weakness` | 学生薄弱知识点（mastery < 0.6） |
|
||||||
|
| GET | `/analytics/student/{student_id}/errorbook` | 学生错题本 |
|
||||||
|
|
||||||
|
**gRPC 契约**（analytics.proto，**待实现**）：
|
||||||
|
|
||||||
|
- `GetClassPerformance(GetClassPerformanceRequest) → ClassPerformance`
|
||||||
|
- `GetStudentWeakness(GetStudentWeaknessRequest) → StudentWeakness`
|
||||||
|
- `GetLearningTrend(GetLearningTrendRequest) → LearningTrend`（**当前 HTTP 未暴露**）
|
||||||
|
|
||||||
|
**发布的领域事件**：
|
||||||
|
|
||||||
|
| 事件 | Topic（004 §7.2） | 触发时机 | 消费者（004 §7.3） |
|
||||||
|
| ---------------- | ----------------------------- | -------------- | --------------------------------------- |
|
||||||
|
| `MasteryUpdated` | `edu.insight.mastery.updated` | 掌握度计算完成 | core-edu（推荐个性化练习）、msg（预警） |
|
||||||
|
|
||||||
|
> **当前未实现发布**：data-ana 当前只消费不发布。掌握度计算完成后应通过 Kafka 发布 `MasteryUpdated`，下游 core-edu / msg 消费。阶段 2 设计需补全此发布链路（Python 无 Outbox 模式，需评估直接 producer 还是引入 Outbox 表）。
|
||||||
|
|
||||||
|
- **错误码前缀**：`DATA_ANA_*`（待定义清单，见阶段 2 §6）
|
||||||
|
- **缓存**：当前无 Redis 缓存；004 §6.3 学情宽表走 ClickHouse 实时，CDC 同步延迟 < 5s
|
||||||
|
|
||||||
|
### 4. 我的技术栈
|
||||||
|
|
||||||
|
- 语言：Python 3.12+
|
||||||
|
- 框架：FastAPI 0.115+ / uvicorn
|
||||||
|
- ORM / 客户端：`clickhouse-connect`（HTTP 协议，非原生协议）
|
||||||
|
- 消息：`aiokafka`（CDC 消费者，AIOKafkaConsumer）
|
||||||
|
- 配置：`pydantic-settings` BaseSettings（env_prefix=""，全大写环境变量）
|
||||||
|
- 可观测：
|
||||||
|
- 日志：`structlog` 24.x（`make_filtering_bound_logger`，**注意**：旧版 `make_filtering_logger` 已废弃）
|
||||||
|
- 指标：`prometheus-client` + `make_asgi_app()` 挂载 `/metrics`
|
||||||
|
- 链路：`opentelemetry-sdk` + `OTLPSpanExporter` + `FastAPIInstrumentor.instrument_app(app)`
|
||||||
|
- 序列化：JSON（Debezium 事件 `schemas.enable=false`，直接 `json.loads`）
|
||||||
|
- 测试：pytest + pytest-asyncio（**当前 0% 覆盖率**）
|
||||||
|
|
||||||
|
### 5. 我的阶段归属
|
||||||
|
|
||||||
|
- **P4 内容分析阶段（M11-M13）**：建 DataAna 服务 + CDC 链路落地
|
||||||
|
- **退出标准**（pending-features P4）：学生查看学情诊断 ClickHouse 宽表 5s 内返回 + CDC 链路延迟 < 5s
|
||||||
|
- **依赖上游**：
|
||||||
|
- P1 地基：api-gateway 路由 + arch.db 扫描器 Python 支持
|
||||||
|
- P3 核心教学：core-edu 写成绩到 MySQL（Debezium 监听 binlog）
|
||||||
|
- P4 同期：content 服务（提供知识点 ID 供掌握度计算）
|
||||||
|
- **下游依赖我**：
|
||||||
|
- P5 ai 服务通过 gRPC 查询学情数据（004 §4.1：AI → DataAna gRPC）
|
||||||
|
- P5 msg 服务消费 `mastery.updated` 触发预警
|
||||||
|
|
||||||
|
### 6. 我需要对齐的黄金模板项（对照 classes 服务 + Python 规范）
|
||||||
|
|
||||||
|
> Python 服务无 NestJS 装饰器体系，权限校验等通过等价方式实现。
|
||||||
|
|
||||||
|
- [ ] 权限装饰器等价物：**当前 HTTP 端点全部裸露，无权限校验**。Gateway 层做 JWT 校验，但 data-ana 本身未校验 `x-user-id` / DataScope。**阶段 2 需设计 FastAPI Depends 权限依赖 + DataScope 过滤注入**
|
||||||
|
- [ ] 错误码前缀统一：**当前无错误码体系**，降级时返回 `degraded: true` 标记但无业务错误码。**阶段 2 需定义 `DATA_ANA_*` 错误码清单**
|
||||||
|
- [x] logger / metrics / tracer 三支柱（已具备，见 main.py + clickhouse_client.py）
|
||||||
|
- [x] `/healthz` + `/readyz` 健康检查（已具备，readyz 含 ClickHouse ping + CDC 状态）
|
||||||
|
- [ ] 优雅关闭 SIGTERM：当前 lifespan 仅关闭 CDC task + ClickHouse client，**未注册 SIGTERM 信号处理器**显式 drain
|
||||||
|
- [ ] 测试覆盖率 ≥ 80%：**当前 0%**，无 tests/ 目录
|
||||||
|
- [ ] Dockerfile 多阶段构建：**当前单阶段**（`FROM python:3.12-slim` → `uv sync` → `COPY src`），非多阶段
|
||||||
|
- [ ] Pydantic 输入验证：**当前端点直接接收 path param，无 Pydantic 请求模型校验**（应补 `ClassPerformanceResponse` 等 response_model）
|
||||||
|
- [x] 配置通过 pydantic-settings 管理（已具备）
|
||||||
|
- [x] 异步优先（async def，aiokafka async consumer）
|
||||||
|
- [ ] 类型注解强制：**部分函数缺返回值标注**（如 `init_logger` 返回 `BoundLogger` 但 `_logger` 全局变量标注 `None`，需统一）
|
||||||
|
- [ ] ruff check 零错误：需阶段 2 验证
|
||||||

- api-gateway 直接 HTTP 代理 `/api/v1/ai/*` → ai:3008（见 [api-gateway main.go:138-139](../../services/api-gateway/main.go)）
|
||||||
|
- teacher-bff 聚合 AI 出题/优化能力（004 §4.1：BFF → ai，当前 REST）
|
||||||
|
- **下游**：
|
||||||
|
- content 服务（gRPC 查询知识点 / 题库，004 §4.1：AI → Content gRPC）
|
||||||
|
- data-ana 服务（gRPC 查询学情数据，004 §4.1：AI → DataAna gRPC）
|
||||||
|
- LLM Provider（外部 HTTP，OpenAI 兼容 REST API）
|
||||||
|
- **通信方式**：
|
||||||
|
- 入口：当前 REST（`/ai/chat`、`/ai/chat/stream`、`/ai/generate/question`、`/ai/optimize/expression`）；目标态（ai.proto）转 **gRPC** 暴露 `AiService`（含 `StreamChat` 流式 RPC）
|
||||||
|
- 出口：gRPC 调 content / data-ana（**当前未实现，仅 LLM HTTP 调用**）；SSE 流式对前端
|
||||||
|
- **端口**：3008（见 [ai config.py:8](../../services/ai/src/ai/config.py) + [api-gateway config.go:57](../../services/api-gateway/internal/config/config.go)）
|
||||||
|
|
||||||
|
### 2. 我的限界上下文
|
||||||
|
|
||||||
|
- **聚合职责**：LLM 调用网关 + 教学场景 AI 编排（备课 / 出题 / 表达优化），承载 **D6 智能洞察领域**的"生成"子域
|
||||||
|
- **聚合根 / 实体**：
|
||||||
|
- `ChatConversation`（聊天会话，**待实现**，当前无状态）
|
||||||
|
- `GeneratedQuestion`（生成的题目，待审核入库）
|
||||||
|
- `PromptTemplate`（Prompt 模板，**待实现**）
|
||||||
|
- `UsageRecord`（用量计费记录，**待实现**）
|
||||||
|
- **业务领域**：D6 智能洞察（与 data-ana 共享，data-ana 偏"分析"，ai 偏"生成"）
|
||||||
|
- **我不负责**：
|
||||||
|
- 不负责题库存储（→ content 服务，ai 生成后调 content.CreateQuestions 入库）
|
||||||
|
- 不负责学情计算（→ data-ana 服务，ai 查询学情用于个性化出题）
|
||||||
|
- 不负责通知投递（→ msg 服务）
|
||||||
|
- 不持有业务状态（无 DB 写入，无 Outbox；用量计费记录可走 Kafka 事件给 data-ana 落 ClickHouse）
|
||||||
|
- **数据自治**：**无独占数据库**（设计上无状态；用量计费通过 Kafka 事件外发）
|
||||||
|
|
||||||
|
### 3. 我与外部的契约
|
||||||
|
|
||||||
|
#### 消费的 proto message
|
||||||
|
|
||||||
|
| 来源 | message / service | 用途 |
|
||||||
|
| --------------- | ---------------------------------------- | --------------------------------------- |
|
||||||
|
| content.proto | `KnowledgeGraphService.GetPrerequisites` | 查询知识点前置依赖用于出题上下文 |
|
||||||
|
| content.proto | `KnowledgeGraphService.GetLearningPath` | 查询学生学习路径用于个性化出题 |
|
||||||
|
| analytics.proto | `AnalyticsService.GetStudentWeakness` | 查询学生薄弱知识点用于靶向出题 |
|
||||||
|
| analytics.proto | `AnalyticsService.GetLearningTrend` | 查询学习趋势用于难度调节 |
|
||||||
|
| ai.proto | `ChatRequest` 等 | gRPC 暴露契约（**待实现 gRPC server**） |
|
||||||
|
|
||||||
|
#### 暴露的 API / 事件
|
||||||
|
|
||||||
|
**HTTP 端点**（当前实现，见 [main.py](../../services/ai/src/ai/main.py)）：
|
||||||
|
|
||||||
|
| method | path | 说明 |
|
||||||
|
| ------ | ------------------------- | ---------------------------- |
|
||||||
|
| GET | `/healthz` | liveness |
|
||||||
|
| GET | `/readyz` | readiness（含 LLM 是否配置） |
|
||||||
|
| GET | `/metrics` | Prometheus 指标 |
|
||||||
|
| POST | `/ai/chat` | LLM 聊天（非流式） |
|
||||||
|
| POST | `/ai/chat/stream` | LLM 流式聊天（SSE） |
|
||||||
|
| POST | `/ai/generate/question` | 生成题目 |
|
||||||
|
| POST | `/ai/optimize/expression` | 优化表达 |
|
||||||
|
|
||||||
|
**gRPC 契约**（ai.proto，**待实现**）：
|
||||||
|
|
||||||
|
- `Chat(ChatRequest) → ChatResponse`
|
||||||
|
- `StreamChat(ChatRequest) → stream ChatChunk`（流式 RPC）
|
||||||
|
- `GenerateQuestion(GenerateQuestionRequest) → GeneratedQuestion`
|
||||||
|
- `OptimizeExpression(OptimizeExpressionRequest) → OptimizedExpression`
|
||||||
|
|
||||||
|
**发布的领域事件**：**当前无发布**。设计上可发布 `AIUsageRecorded` 事件（用量计费），由 data-ana 消费落 ClickHouse。004 §7.2 未列出此 topic，**阶段 2 需与 coord 确认是否新增 `edu.insight.ai.usage` topic**。
|
||||||
|
|
||||||
|
- **错误码前缀**：`AI_*`（待定义清单，见阶段 2 §6）
|
||||||
|
- **降级策略**：LLM API key 为空或调用失败时返回 `degraded: true` 骨架响应（见 [llm_client.py](../../services/ai/src/ai/llm_client.py)）
|
||||||
|
|
||||||
|
### 4. 我的技术栈
|
||||||
|
|
||||||
|
- 语言：Python 3.12+
|
||||||
|
- 框架：FastAPI 0.115+ / uvicorn
|
||||||
|
- LLM 客户端：`httpx` 异步直接调 OpenAI 兼容 REST API（**不依赖 openai SDK**，见 [llm_client.py:1-7](../../services/ai/src/ai/llm_client.py)）
|
||||||
|
- 配置：`pydantic-settings` BaseSettings（env_prefix=""）
|
||||||
|
- 可观测：
|
||||||
|
- 日志：`structlog`
|
||||||
|
- 指标：`prometheus-client` + `make_asgi_app()`
|
||||||
|
- 链路：`opentelemetry-sdk` + `OTLPSpanExporter` + `FastAPIInstrumentor`（dev_mode=true 时跳过 exporter 初始化避免本地无 collector 报错）
|
||||||
|
- 流式响应：FastAPI `StreamingResponse` + `AsyncGenerator`，SSE 格式 `data: <chunk>\n\n`
|
||||||
|
- 测试：pytest（**当前 0% 覆盖率**）
|
||||||
|
|
||||||
|
### 5. 我的阶段归属
|
||||||
|
|
||||||
|
- **P5 沟通与 AI 阶段（M14-M16）**：建 AI 网关 + LLM Provider 适配 + 流式 SSE
|
||||||
|
- **退出标准**（pending-features P5）：AI 辅助出题流式返回 + 题库全文检索 < 200ms（ES 部分由 ai05 负责）
|
||||||
|
- **依赖上游**：
|
||||||
|
- P1 地基：api-gateway 路由
|
||||||
|
- P4 内容分析：content 服务（gRPC 查询知识点 / 题库）+ data-ana 服务（gRPC 查询学情）
|
||||||
|
- 外部：LLM Provider API key（OpenAI / Anthropic / 百川 / 本地模型）
|
||||||
|
- **下游依赖我**：
|
||||||
|
- P5 teacher-bff 聚合 AI 出题 mutation（004 §9.3：教师用 AI 出题并发布到班级）
|
||||||
|
- P5 teacher-portal SSE 流式 AI 对话（前端）
|
||||||
|
|
||||||
|
### 6. 我需要对齐的黄金模板项（对照 classes 服务 + Python 规范）
|
||||||
|
|
||||||
|
- [ ] 权限装饰器等价物：**当前 HTTP 端点全部裸露，无权限校验**。阶段 2 需设计 FastAPI Depends 权限依赖（AI 出题需 `AI_QUESTION_GENERATE` 权限，表达优化需 `AI_EXPRESSION_OPTIMIZE`）
|
||||||
|
- [ ] 错误码前缀统一：**当前无错误码体系**，降级时返回 `degraded: true` 但无业务错误码。**阶段 2 需定义 `AI_*` 错误码清单**
|
||||||
|
- [x] logger / metrics / tracer 三支柱（已具备）
|
||||||
|
- [x] `/healthz` + `/readyz` 健康检查（已具备，readyz 含 LLM 配置状态）
|
||||||
|
- [ ] 优雅关闭 SIGTERM：当前 lifespan 无显式 drain（LLM 流式请求需等待完成）
|
||||||
|
- [ ] 测试覆盖率 ≥ 80%：**当前 0%**，无 tests/ 目录
|
||||||
|
- [ ] Dockerfile 多阶段构建：**当前单阶段**（`FROM python:3.12-slim`）
|
||||||
|
- [ ] Pydantic 输入验证：**当前仅 `ChatRequest` 是 BaseModel，`generate/question` 和 `optimize/expression` 直接接收 `prompt: str` / `text: str` query param，无请求体模型**。阶段 2 需补完整 Pydantic 请求/响应模型
|
||||||
|
- [x] 配置通过 pydantic-settings 管理（已具备）
|
||||||
|
- [x] 异步优先（httpx async + AsyncGenerator stream）
|
||||||
|
- [x] 类型注解强制（已基本符合，main.py 函数返回值已标注）
|
||||||
|
- [ ] LLM Provider 适配器模式：**当前仅 OpenAI 兼容 REST**，未抽象 Provider 接口。阶段 2 需设计 `LLMProvider` 抽象 + OpenAI/Anthropic/百川/本地 多适配器
|
||||||
|
- [ ] Prompt 模板管理：**当前 Prompt 硬编码在 main.py**，阶段 2 需设计模板管理（DB 或文件）
|
||||||
|
- [ ] 用量计费 / 频率限制：**当前无用量记录和限流**，阶段 2 需设计（Kafka 事件 + Redis 限流）
|
||||||
|
- [ ] 备课工作流：**当前未实现**，pending-features P5 要求"分析学情 → 推荐知识点 → 生成题目 → 教师审核 → 入库"完整工作流
|
||||||
|
- [ ] ruff check 零错误：需阶段 2 验证
|
||||||

|
|
||||||
|
### 审计发现的关键差距清单
|
||||||
|
|
||||||
|
#### data-ana 关键差距（按优先级）
|
||||||
|
|
||||||
|
1. **P0 权限校验缺失**：所有 `/analytics/*` 端点裸露，无 DataScope 过滤。学生 A 可查询学生 B 的错题本（越权风险）。阶段 2 必须设计 `Depends(require_permission)` + `Depends(inject_data_scope)` 依赖注入
|
||||||
|
2. **P0 gRPC server 未实现**：analytics.proto 定义了 `AnalyticsService` 但 data-ana 当前仅 HTTP。004 §4.1 明确 BFF → 业务服务走 gRPC，阶段 2 需引入 `grpc.aio` + `betterproto` 实现 gRPC server
|
||||||
|
3. **P1 事件发布缺失**：`edu.insight.mastery.updated` 事件未发布，下游 core-edu/msg 无法消费。需设计掌握度计算 + Kafka producer 发布链路
|
||||||
|
4. **P1 ClickHouse schema 不规范**：当前 `student_dashboard_view` 实为 MergeTree 表（注释提到应为 ReplacingMergeTree(last_updated) 实现幂等去重），无 DDL 文件管理。阶段 2 需产出完整 ClickHouse DDL（5 张宽表：考试/作业/成绩/掌握度/出勤）
|
||||||
|
5. **P2 测试覆盖率 0%**：无 tests/ 目录，pytest 未配置
|
||||||
|
6. **P2 Dockerfile 单阶段**：未做多阶段构建（builder + runtime），镜像体积大
|
||||||
|
7. **P2 掌握度计算算法缺失**：当前 `_handle_grades_event` 用 `score / 100.0` 简化，未实现 pending-features 要求的"加权滑动平均"算法
|
||||||
|
8. **P2 无 Pydantic 响应模型**：端点返回 `dict` 而非 `BaseModel`，无 `response_model` 校验
|
||||||
|
|
||||||
|
#### ai 关键差距（按优先级）
|
||||||
|
|
||||||
|
1. **P0 权限校验缺失**：所有 `/ai/*` 端点裸露，AI 出题等敏感操作无权限校验
|
||||||
|
2. **P0 gRPC server 未实现**：ai.proto 定义了 `AiService`（含 `StreamChat` 流式 RPC）但 ai 当前仅 HTTP。阶段 2 需引入 `grpc.aio` 实现 gRPC server + 流式 RPC
|
||||||
|
3. **P0 gRPC client 未实现**：004 §4.1 明确 AI → Content / AI → DataAna 走 gRPC，当前未实现。阶段 2 需设计 gRPC client 调用 content / data-ana
|
||||||
|
4. **P1 LLM Provider 适配器缺失**：当前 `llm_client.py` 仅 OpenAI 兼容 REST，未抽象 Provider 接口。pending-features P5 要求"LLM Provider 适配（OpenAI/Anthropic/百川/本地模型）"
|
||||||
|
5. **P1 Prompt 模板管理缺失**：system prompt 硬编码在 main.py，无模板管理。阶段 2 需设计模板存储（文件 or DB）+ 模板渲染
|
||||||
|
6. **P1 备课工作流缺失**：pending-features P5 要求"分析学情 → 推荐知识点 → 生成题目 → 教师审核 → 入库"完整工作流，当前仅"生成题目"单步
|
||||||
|
7. **P1 用量计费 / 频率限制缺失**：无用量记录（token 消耗）、无频率限制（用户可无限调用 LLM）。阶段 2 需设计 Redis 限流 + Kafka 事件外发用量
|
||||||
|
8. **P2 测试覆盖率 0%**：无 tests/ 目录
|
||||||
|
9. **P2 Dockerfile 单阶段**：未做多阶段构建
|
||||||
|
10. **P2 Pydantic 输入验证不完整**：`generate/question` 和 `optimize/expression` 直接接收 query param，无请求体模型

## 阶段 1 待 coord 交叉审查的跨模块契约对齐项
|
||||||
|
|
||||||
|
以下项需 coord 在交叉审查时仲裁（见 ai-allocation.md §8）：
|
||||||
|
|
||||||
|
| # | 议题 | 涉及方 | 当前状态 | ai06 建议 |
|
||||||
|
| --- | -------------------------------------------------------- | ---------------------------------------------- | -------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------- |
|
||||||
|
| 1 | **data-ana 是否发布 `edu.insight.mastery.updated` 事件** | data-ana → core-edu / msg | 004 §7.2 列出此 topic，但当前 data-ana 未实现发布 | 阶段 2 设计发布链路；Python 无 Outbox，建议直接 Kafka producer（掌握度计算是派生数据，非事务写） |
|
||||||
|
| 2 | **ai 是否发布 `edu.insight.ai.usage` 用量事件** | ai → data-ana | 004 §7.2 未列出此 topic | 建议 coord 新增此 topic 用于用量计费落 ClickHouse；若 coord 不同意则 ai 自建用量记录表（破坏无状态原则） |
|
||||||
|
| 3 | **data-ana / ai 是否需要实现 gRPC server** | data-ana / ai ← teacher-bff / student-bff / ai | 004 §4.1 明确 BFF → 业务服务走 gRPC，analytics.proto / ai.proto 已定义 service，但当前两服务仅 HTTP | 阶段 2 引入 `grpc.aio` + `betterproto` 实现 gRPC server；HTTP 端点保留作为 Gateway 直连降级通道 |
|
||||||
|
| 4 | **CDC 直连 vs Outbox 领域事件双通道** | data-ana ← core-edu | 当前 data-ana 走 Debezium CDC（监听 binlog），不消费 core-edu Outbox 事件（events.proto） | 维持 CDC 为主通道（ADR-008 决策）；events.proto 作为业务语义补充，待 P4 后期评估是否双消费 |
|
||||||
|
| 5 | **data-ana DataScope 过滤实现位置** | data-ana + iam | 004 §5.3 DataScope 6 级，业务服务在 Repository 层注入 WHERE；data-ana 是 ClickHouse 查询无 Repository 层 | 阶段 2 在 ClickHouse 查询 SQL 拼接时注入 DataScope WHERE（学生只能看自己，教师看本班，校管理员看本校）；需 iam 提供 `getEffectiveDataScope(userId)` API |
|
||||||
|
| 6 | **ai 备课工作流是否引入 Temporal** | ai + coord | 004 §2.3 列出 Temporal 用于"工作流编排（考试生命周期、AI 编排）"，P3 已引入 Temporal 试点 | 阶段 2 评估：简单工作流（4 步）可用 FastAPI BackgroundTasks；复杂工作流（含教师审核等待）建议 Temporal；待 coord 仲裁 |
|
||||||
|
| 7 | **LLM Provider 切换的配置化** | ai + coord | 当前 ai config.py 仅 OpenAI + Anthropic 字段 | 阶段 2 设计 `LLMProvider` 抽象 + 配置化路由（按 model 名路由到不同 provider）；本地模型走 Ollama REST API |
|
||||||
|
| 8 | **data-ana ClickHouse DDL 管理位置** | data-ana + coord | 当前无 DDL 文件，宽表手动创建 | 建议 coord 在 `infra/clickhouse/` 下建立 DDL 目录（类似 MySQL init.sql），data-ana 提供 DDL 内容 |
|
||||||
|
|
||||||

|
||||||
|
|
||||||
|
## 阶段 1 总结
|
||||||
|
|
||||||
|
ai06 已完成阶段 1 全局理解，产出本确认书。核心结论：
|
||||||
|
|
||||||
|
1. **data-ana**（P4）：CDC 链路已跑通（Debezium → Kafka → ClickHouse），3 个分析端点已实现降级模式。**关键差距**：权限校验、gRPC server、事件发布（mastery.updated）、ClickHouse DDL 规范化、掌握度算法、测试覆盖。
|
||||||
|
2. **ai**（P5）：LLM 客户端已实现降级模式（httpx 异步 + SSE 流式），4 个端点已实现。**关键差距**：权限校验、gRPC server + client、LLM Provider 适配器、Prompt 模板管理、备课工作流、用量计费、测试覆盖。
|
||||||
|
3. **跨模块契约**：8 项待 coord 仲裁，最关键的是 gRPC server 实现决策（影响阶段 2 设计核心）和事件发布 topic 新增决策。
|
||||||
|
|
||||||
|
下一步进入阶段 2，按 ai-allocation.md §7 模板产出 data-ana 与 ai 的模块架构设计文档。

## 设计原则与全局约束
|
||||||
|
|
||||||
|
本设计遵循以下强制约束（来自 project_rules.md + coding-standards.md + 004）：
|
||||||
|
|
||||||
|
1. **契约先行**：proto 已定义（analytics.proto / ai.proto），实现前不修改 proto，如需修改走 coord 流程
|
||||||
|
2. **CQRS 读写分离**：data-ana 是纯读模型服务（无 MySQL 写），ClickHouse 宽表由 CDC 投影构建
|
||||||
|
3. **事件驱动**：data-ana 消费 CDC + 领域事件；ai 不参与事件流（无状态）
|
||||||
|
4. **gRPC 优先**：004 §4.1 明确 BFF → 业务服务走 gRPC，两服务需实现 gRPC server（HTTP 保留作 Gateway 直连降级）
|
||||||
|
5. **DataScope 过滤**：004 §5.3 DataScope 6 级在查询层注入 WHERE
|
||||||
|
6. **三支柱可观测**：structlog + prometheus-client + OpenTelemetry（已具备，需补业务指标）
|
||||||
|
7. **降级模式**：外部依赖（ClickHouse / LLM / 下游 gRPC）不可用时返回骨架数据 + `degraded: true`
|
||||||
|
8. **Python 规范**：pydantic-settings 配置 / Pydantic 模型校验 / async 优先 / 类型注解强制 / ruff 零错误

||||||
|
|
||||||
|
C1 --> C3
|
||||||
|
C3 --> C2
|
||||||
|
C3 --> R1
|
||||||
|
C1 --> KAFKA
|
||||||
|
```
|
||||||
|
|
||||||
|
**分层规则**：
|
||||||
|
|
||||||
|
- **入口层**：HTTP（保留作 Gateway 直连降级）+ gRPC（主入口，BFF 调用）。两入口共享同一 Application Service
|
||||||
|
- **中间件层**：FastAPI Depends 链（`AuthDepends` → `DataScopeDepends`）；gRPC 用 server interceptor 注入身份元数据
|
||||||
|
- **应用服务层**：编排查询 / 计算掌握度 / 发布事件，不直接访问存储
|
||||||
|
- **数据访问层**：ClickHouse 查询封装 + Kafka producer + gRPC client（调 iam）
|
||||||
|
- **CDC 消费者**：独立后台任务（lifespan 启动），与 HTTP/gRPC 入口解耦
|
||||||
|
|
||||||
|
## 2. 领域模型
|
||||||
|
|
||||||
|
data-ana 是**纯读模型服务**，不持有写聚合根。领域模型为**视图聚合**（ClickHouse 物化）：
|
||||||
|
|
||||||
|
### 聚合根（视图型）
|
||||||
|
|
||||||
|
| 聚合根 | 含义 | 物化载体 | 不变式 |
|
||||||
|
| ------------------ | ---------------- | ----------------------------------------- | ------------------------------------------------------------- |
|
||||||
|
| `StudentDashboard` | 学生学情宽表 | ClickHouse `student_dashboard_view` | 同一 (student_id, exam_id, knowledge_point_id) 仅保留最新版本 |
|
||||||
|
| `ClassPerformance` | 班级成绩聚合 | ClickHouse 即时聚合（不物化） | 聚合维度为 class_id + 时间窗 |
|
||||||
|
| `StudentErrorBook` | 学生错题本 | ClickHouse `student_errors` | 同一 (student_id, question_id) 累计 error_count |
|
||||||
|
| `MasterySnapshot` | 知识点掌握度快照 | ClickHouse `mastery_snapshot`（**新增**） | 同一 (student_id, knowledge_point_id) 保留历史版本 |
|
||||||
|
|
||||||
|
### 值对象
|
||||||
|
|
||||||
|
- `WeakPoint`：knowledge_point_id + title + mastery_level
|
||||||
|
- `TrendPoint`：date + score
|
||||||
|
- `DataScope`：level (SELF/CLASS/GRADE/SCHOOL/DISTRICT/ALL) + scope_ids（具体可见的 class_id / grade_id 列表）
|
||||||
|
|
||||||
|
### 聚合间通信
|
||||||
|
|
||||||
|
- 同服务内：直接函数调用（Application Service → Repository）
|
||||||
|
- 跨服务：仅通过 Kafka 事件（发布 `mastery.updated`）+ gRPC（调 iam 查 DataScope）
|
||||||
|
|
||||||
|
## 3. 数据模型（ClickHouse DDL）
|
||||||
|
|
||||||
|
> DDL 文件由 coord 统一管理在 `infra/clickhouse/ddl/`（待 coord 建立），data-ana 提供内容。
|
||||||
|
|
||||||
|
### 3.1 宽表 `student_dashboard_view`
|
||||||
|
|
||||||
|
```sql
|
||||||
|
-- 学生学情宽表：每次成绩写入产生一行，按 ORDER BY 去重保留最新版本
|
||||||
|
CREATE TABLE IF NOT EXISTS student_dashboard_view
|
||||||
|
(
|
||||||
|
student_id String,
|
||||||
|
class_id String,
|
||||||
|
exam_id String,
|
||||||
|
subject_id String,
|
||||||
|
score Float64,
|
||||||
|
rank_in_class UInt32,
|
||||||
|
knowledge_point_id String,
|
||||||
|
mastery_level Float32, -- 0.0-1.0
|
||||||
|
error_count UInt32,
|
||||||
|
last_updated DateTime64(3, 'UTC')
|
||||||
|
)
|
||||||
|
ENGINE = ReplacingMergeTree(last_updated)
|
||||||
|
PARTITION BY toYYYYMM(last_updated)
|
||||||
|
ORDER BY (student_id, exam_id, knowledge_point_id)
|
||||||
|
SETTINGS index_granularity = 8192;
|
||||||
|
```
|
||||||
|
|
||||||
|
**索引策略**：
|
||||||
|
|
||||||
|
- ORDER BY `(student_id, exam_id, knowledge_point_id)`：主键索引，支持按学生查学情、按考试查成绩、按知识点查掌握度
|
||||||
|
- PARTITION BY `toYYYYMM(last_updated)`：按月分区，支持历史数据归档
|
||||||
|
- ReplacingMergeTree(last_updated)：同 ORDER BY 自动去重，保留 last_updated 最大版本（幂等消费保证）
|
||||||
|
|
||||||
|
### 3.2 错题本 `student_errors`
|
||||||
|
|
||||||
|
```sql
|
||||||
|
CREATE TABLE IF NOT EXISTS student_errors
|
||||||
|
(
|
||||||
|
student_id String,
|
||||||
|
question_id String,
|
||||||
|
knowledge_point_id String,
|
||||||
|
error_count UInt32,
|
||||||
|
last_error_time DateTime64(3, 'UTC'),
|
||||||
|
content String
|
||||||
|
)
|
||||||
|
ENGINE = ReplacingMergeTree(last_error_time)
|
||||||
|
PARTITION BY toYYYYMM(last_error_time)
|
||||||
|
ORDER BY (student_id, question_id);
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3.3 掌握度快照 `mastery_snapshot`（**新增**）
|
||||||
|
|
||||||
|
```sql
|
||||||
|
-- 知识点掌握度历史快照：每次掌握度计算产生新版本，支持趋势查询
|
||||||
|
CREATE TABLE IF NOT EXISTS mastery_snapshot
|
||||||
|
(
|
||||||
|
student_id String,
|
||||||
|
knowledge_point_id String,
|
||||||
|
subject_id String,
|
||||||
|
mastery_level Float32,
|
||||||
|
calculated_at DateTime64(3, 'UTC'),
|
||||||
|
calculation_method LowCardinality(String) -- 'weighted_moving_avg' / 'simple_avg'
|
||||||
|
)
|
||||||
|
ENGINE = MergeTree
|
||||||
|
PARTITION BY toYYYYMM(calculated_at)
|
||||||
|
ORDER BY (student_id, knowledge_point_id, calculated_at);
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3.4 用量计费 `ai_usage_log`（**新增，供 ai 服务写入**）
|
||||||
|
|
||||||
|
```sql
|
||||||
|
-- AI 用量记录：ai 服务通过 Kafka 事件投递，data-ana 消费落库
|
||||||
|
CREATE TABLE IF NOT EXISTS ai_usage_log
|
||||||
|
(
|
||||||
|
request_id String,
|
||||||
|
user_id String,
|
||||||
|
provider LowCardinality(String), -- 'openai' / 'anthropic' / 'baichuan' / 'local'
|
||||||
|
model LowCardinality(String),
|
||||||
|
prompt_tokens UInt32,
|
||||||
|
completion_tokens UInt32,
|
||||||
|
total_tokens UInt32,
|
||||||
|
latency_ms UInt32,
|
||||||
|
success Boolean,
|
||||||
|
occurred_at DateTime64(3, 'UTC')
|
||||||
|
)
|
||||||
|
ENGINE = MergeTree
|
||||||
|
PARTITION BY toYYYYMM(occurred_at)
|
||||||
|
ORDER BY (user_id, occurred_at);
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3.5 读写分离策略
|
||||||
|
|
||||||
|
| 操作 | 路径 | 说明 |
|
||||||
|
| -------------- | ----------------------------------- | ------------------------------------------ |
|
||||||
|
| 学情查询 | ClickHouse 宽表 | 实时聚合，亚秒级响应 |
|
||||||
|
| 错题本查询 | ClickHouse student_errors | 实时查询 |
|
||||||
|
| 掌握度趋势 | ClickHouse mastery_snapshot | 历史快照 |
|
||||||
|
| 掌握度计算 | CDC 触发 → 内存计算 → 写 ClickHouse | 派生数据，非事务写 |
|
||||||
|
| DataScope 解析 | gRPC 调 iam | 实时查询，结果 Redis 缓存 5min（004 §6.3） |
|
||||||
|
|
||||||
|
## 4. API 设计
|
||||||
|
|
||||||
|
### 4.1 HTTP 端点（保留作 Gateway 直连降级）
|
||||||
|
|
||||||
|
| method | path | 权限 | 请求 | 响应 | 说明 |
|
||||||
|
| ------ | ------------------------------------------- | ----------------------------- | ------------------------------------------------ | ----------------------------------------------------- | -------------------------------- |
|
||||||
|
| GET | `/healthz` | — | — | `{status, service}` | liveness |
|
||||||
|
| GET | `/readyz` | — | — | `{status, ready, degraded, clickhouse, cdc_consumer}` | readiness |
|
||||||
|
| GET | `/metrics` | — | — | Prometheus 格式 | 指标 |
|
||||||
|
| GET | `/analytics/class/{class_id}/performance` | `ANALYTICS_CLASS_READ` | query: `subject_id?`, `start_date?`, `end_date?` | `ClassPerformanceResponse` | 班级成绩分析 |
|
||||||
|
| GET | `/analytics/student/{student_id}/weakness` | `ANALYTICS_STUDENT_READ` | query: `subject_id?` | `StudentWeaknessResponse` | 学生薄弱知识点（DataScope 过滤） |
|
||||||
|
| GET | `/analytics/student/{student_id}/errorbook` | `ANALYTICS_STUDENT_READ` | query: `page?`, `size?` | `StudentErrorBookResponse` | 学生错题本（DataScope 过滤） |
|
||||||
|
| GET | `/analytics/student/{student_id}/trend` | `ANALYTICS_STUDENT_READ` | query: `start_date`, `end_date`, `subject_id?` | `LearningTrendResponse` | 学习趋势（**新增**） |
|
||||||
|
| GET | `/analytics/dashboard/teacher/{user_id}` | `ANALYTICS_TEACHER_DASHBOARD` | query: `class_id?` | `TeacherDashboardResponse` | 教师仪表盘聚合（**新增**） |
|
||||||
|
|
||||||
|
### 4.2 gRPC 契约（analytics.proto，待实现 server）
|
||||||
|
|
||||||
|
| RPC | 请求 | 响应 | 权限 |
|
||||||
|
| --------------------- | ------------------------------------------------------------------------ | ------------------ | ------------------------ |
|
||||||
|
| `GetClassPerformance` | `GetClassPerformanceRequest{class_id, subject_id, start_date, end_date}` | `ClassPerformance` | `ANALYTICS_CLASS_READ` |
|
||||||
|
| `GetStudentWeakness` | `GetStudentWeaknessRequest{student_id, subject_id}` | `StudentWeakness` | `ANALYTICS_STUDENT_READ` |
|
||||||
|
| `GetLearningTrend` | `GetLearningTrendRequest{student_id, start_date, end_date}` | `LearningTrend` | `ANALYTICS_STUDENT_READ` |
|
||||||
|
|
||||||
|
**权限校验**：gRPC server interceptor 从 metadata 提取 `x-user-id` / `x-user-roles` / `x-data-scope`，调用 `AuthDepends` 等价逻辑。
|
||||||
|
|
||||||
|
### 4.3 Pydantic 请求/响应模型
|
||||||
|
|
||||||
|
```python
|
||||||
|
# 示例：班级成绩分析响应
|
||||||
|
class ClassPerformanceResponse(BaseModel):
|
||||||
|
success: bool
|
||||||
|
data: ClassPerformanceData
|
||||||
|
degraded: bool = False
|
||||||
|
|
||||||
|
class ClassPerformanceData(BaseModel):
|
||||||
|
class_id: str
|
||||||
|
average_score: float
|
||||||
|
pass_rate: float
|
||||||
|
total_students: int
|
||||||
|
scores: list[StudentScore] = [] # 详细成绩列表（受 DataScope 过滤）
|
||||||
|
|
||||||
|
class StudentScore(BaseModel):
|
||||||
|
student_id: str
|
||||||
|
score: float
|
||||||
|
grade: str
|
||||||
|
```
|
||||||
|
|
||||||
|
## 5. 事件设计
|
||||||
|
|
||||||
|
### 5.1 消费的事件
|
||||||
|
|
||||||
|
| Topic | 来源 | 消息格式 | 消费动作 |
|
||||||
|
| ------------------------------------------------------ | ------------------------------------------------- | --------------------------------------------- | ---------------------------------------------------------------------------- |
|
||||||
|
| `edu-cdc.next_edu_cloud.core_edu_grades` | Debezium CDC（core-edu MySQL） | Debezium JSON（before/after/source/op/ts_ms） | 解析 → 查 ExamCache 填 class_id → 计算掌握度 → upsert student_dashboard_view |
|
||||||
|
| `edu-cdc.next_edu_cloud.core_edu_exams` | Debezium CDC | Debezium JSON | upsert ExamCache（exam_id → class_id, subject_id） |
|
||||||
|
| `edu-cdc.next_edu_cloud.core_edu_homework_submissions` | Debezium CDC（**新增订阅**） | Debezium JSON | 记录作业提交行为 → 更新 student_dashboard_view |
|
||||||
|
| `edu-cdc.next_edu_cloud.classes` | Debezium CDC | Debezium JSON | 同步班级维度（head_teacher_id）用于教师 DataScope |
|
||||||
|
| `edu-cdc.next_edu_cloud.iam_users` | Debezium CDC（**新增订阅**） | Debezium JSON | 同步用户 dataScope 用于查询过滤（避免每次查 iam） |
|
||||||
|
| `edu.insight.ai.usage` | ai 服务 Kafka producer（**待 coord 新增 topic**） | JSON（UsageRecord） | 落 ai_usage_log 表 |
|
||||||
|
|
||||||
|
**幂等性**：
|
||||||
|
|
||||||
|
- CDC 事件：依赖 ClickHouse `ReplacingMergeTree(last_updated)` 引擎按 ORDER BY 去重
|
||||||
|
- 领域事件（若消费）：基于 `event_id` 去重（Redis SETNX，TTL 7 天）
|
||||||
|
|
||||||
|
### 5.2 发布的事件
|
||||||
|
|
||||||
|
| 事件 | Topic | 触发时机 | 消费者 | Payload |
|
||||||
|
| ---------------- | ----------------------------- | ----------------------------------------------- | --------------------------------------------- | -------------------------------------------------------------------------- |
|
||||||
|
| `MasteryUpdated` | `edu.insight.mastery.updated` | 掌握度计算完成（CDC grades 事件触发后异步计算） | core-edu（推荐个性化练习）、msg（掌握度预警） | `{event_id, student_id, knowledge_point_id, mastery_level, calculated_at}` |
|
||||||
|
|
||||||
|
**发布实现**（Python 无 Outbox 模式）：
|
||||||
|
|
||||||
|
- 掌握度计算是**派生数据**（非业务事务写），不需要 Outbox 保证事务一致
|
||||||
|
- 直接用 `aiokafka.AIOKafkaProducer` 发布，`idempotent=true` + 事务性 producer
|
||||||
|
- 失败重试 3 次，仍失败记录日志 + 落 `mastery_publish_failed` 本地表（待 P6 评估是否引入 Outbox）
|
||||||
|
|
||||||
|
## 6. 横切关注点对齐清单
|
||||||
|
|
||||||
|
### 6.1 权限装饰器等价物（FastAPI Depends）
|
||||||
|
|
||||||
|
```python
|
||||||
|
# 权限点常量（与 iam 权限点对齐）
|
||||||
|
class Permissions:
|
||||||
|
ANALYTICS_CLASS_READ = "analytics:class:read"
|
||||||
|
ANALYTICS_STUDENT_READ = "analytics:student:read"
|
||||||
|
ANALYTICS_TEACHER_DASHBOARD = "analytics:teacher:dashboard"
|
||||||
|
|
||||||
|
async def require_permission(permission: str) -> UserContext:
|
||||||
|
"""FastAPI Depends 权限校验.
|
||||||
|
|
||||||
|
从 x-user-id / x-user-roles 头提取身份，校验角色是否含 permission。
|
||||||
|
"""
|
||||||
|
...
|
||||||
|
|
||||||
|
async def inject_data_scope(ctx: UserContext = Depends(require_permission(...)))-> DataScope:
|
||||||
|
"""注入 DataScope（从 iam.getEffectiveDataScope 查询，Redis 缓存 5min）."""
|
||||||
|
...
|
||||||
|
```
|
||||||
|
|
||||||
|
### 6.2 错误码清单（前缀 `DATA_ANA_*`）
|
||||||
|
|
||||||
|
| 错误码 | 触发条件 | HTTP | gRPC status |
|
||||||
|
| --------------------------------- | --------------------------------------- | ------------------- | ------------------ |
|
||||||
|
| `DATA_ANA_UNAUTHORIZED` | 缺失 x-user-id 头或 token 无效 | 401 | UNAUTHENTICATED |
|
||||||
|
| `DATA_ANA_FORBIDDEN` | 角色无对应权限 | 403 | PERMISSION_DENIED |
|
||||||
|
| `DATA_ANA_DATASCOPE_VIOLATION` | 查询目标超出 DataScope 范围 | 403 | PERMISSION_DENIED |
|
||||||
|
| `DATA_ANA_CLICKHOUSE_UNAVAILABLE` | ClickHouse 不可达（降级模式仍返回骨架） | 200 + degraded:true | OK + degraded flag |
|
||||||
|
| `DATA_ANA_INVALID_DATE_RANGE` | start_date > end_date | 400 | INVALID_ARGUMENT |
|
||||||
|
| `DATA_ANA_STUDENT_NOT_FOUND` | student_id 不存在 | 404 | NOT_FOUND |
|
||||||
|
| `DATA_ANA_CLASS_NOT_FOUND` | class_id 不存在 | 404 | NOT_FOUND |
|
||||||
|
| `DATA_ANA_INTERNAL_ERROR` | 未捕获异常 | 500 | INTERNAL |
|
||||||
|
|
||||||
|
### 6.3 Logger 初始化
|
||||||
|
|
||||||
|
- 位置：`main.py` `init_logger()`（已具备）
|
||||||
|
- 配置：`structlog.make_filtering_bound_logger(level)` + `TimeStamper(fmt="iso")` + `ConsoleRenderer`
|
||||||
|
- **改进**：生产环境改用 `structlog.processors.JSONRenderer()`（当前 ConsoleRenderer 适合开发）
|
||||||
|
|
||||||
|
### 6.4 Metrics 指标清单
|
||||||
|
|
||||||
|
| 指标名 | 类型 | 标签 | 描述 |
|
||||||
|
| --------------------------------------------- | --------- | -------------------- | -------------------------- |
|
||||||
|
| `data_ana_http_requests_total` | Counter | method, path, status | HTTP 请求总数 |
|
||||||
|
| `data_ana_http_request_duration_seconds` | Histogram | method, path | HTTP 请求延迟 |
|
||||||
|
| `data_ana_clickhouse_query_duration_seconds` | Histogram | query_type | ClickHouse 查询延迟 |
|
||||||
|
| `data_ana_clickhouse_query_total` | Counter | query_type, status | ClickHouse 查询总数 |
|
||||||
|
| `data_ana_cdc_events_consumed_total` | Counter | table, op | CDC 事件消费总数 |
|
||||||
|
| `data_ana_cdc_event_process_duration_seconds` | Histogram | table | CDC 事件处理延迟 |
|
||||||
|
| `data_ana_cdc_consumer_lag` | Gauge | topic, partition | CDC 消费者 lag |
|
||||||
|
| `data_ana_mastery_calculated_total` | Counter | — | 掌握度计算次数 |
|
||||||
|
| `data_ana_mastery_published_total` | Counter | status | mastery.updated 事件发布数 |
|
||||||
|
| `data_ana_datascope_cache_hits_total` | Counter | — | DataScope 缓存命中 |
|
||||||
|
|
||||||
|
### 6.5 Tracer 初始化
|
||||||
|
|
||||||
|
- 位置：`main.py` `init_tracer()`（已具备）
|
||||||
|
- endpoint：`settings.otel_endpoint` + `/v1/traces`
|
||||||
|
- **改进**：gRPC server 注册 `grpc.aio.ServerInterceptor` 透传 W3C trace context
|
||||||
|
|
||||||
|
### 6.6 /healthz 检查逻辑
|
||||||
|
|
||||||
|
- liveness：仅进程存活（已具备）
|
||||||
|
|
||||||
|
### 6.7 /readyz 检查逻辑
|
||||||
|
|
||||||
|
```python
|
||||||
|
async def readyz() -> dict:
|
||||||
|
return {
|
||||||
|
"status": "ok" if all_ready else "degraded",
|
||||||
|
"ready": all_ready,
|
||||||
|
"degraded": not all_ready,
|
||||||
|
"clickhouse": "ok" | "unreachable" | "not_configured",
|
||||||
|
"cdc_consumer": "running" | "disabled" | "failed",
|
||||||
|
"kafka_brokers": settings.kafka_brokers or None,
|
||||||
|
"iam_grpc": "ok" | "unreachable", # 新增：iam gRPC 连通性
|
||||||
|
"timestamp": datetime.now(UTC).isoformat(),
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### 6.8 优雅关闭顺序
|
||||||
|
|
||||||
|
1. HTTP server stop accepting new requests（uvicorn graceful shutdown）
|
||||||
|
2. gRPC server graceful stop（等待在途 RPC 完成，30s 超时）
|
||||||
|
3. CDC consumer stop（等待在途消息处理完成，commit offset）
|
||||||
|
4. Kafka producer flush + close（确保 mastery.updated 事件已投递）
|
||||||
|
5. ClickHouse client close
|
||||||
|
6. iam gRPC channel close
|
||||||
|
|
||||||
|
**信号处理**：注册 `signal.SIGTERM` handler，触发上述顺序。
|
||||||
|
|
||||||
|
## 7. 与其他模块的交互点（契约清单）
|
||||||
|
|
||||||
|
| 方向 | 对方服务 | 协议 | 接口/事件 | 用途 |
|
||||||
|
| ------ | ------------------------- | ----- | ------------------------------------------------------------------- | ----------------------------- |
|
||||||
|
| 被调用 | api-gateway | HTTP | `/analytics/*` | Gateway 代理 |
|
||||||
|
| 被调用 | teacher-bff / student-bff | gRPC | `AnalyticsService.*` | BFF 聚合查询 |
|
||||||
|
| 被调用 | ai | gRPC | `AnalyticsService.GetStudentWeakness / GetLearningTrend` | AI 个性化出题上下文 |
|
||||||
|
| 调用 | iam | gRPC | `IamService.GetEffectiveDataScope`（**待 proto 新增**） | DataScope 解析 |
|
||||||
|
| 消费 | core-edu（CDC） | Kafka | `edu-cdc.next_edu_cloud.core_edu_grades/exams/homework_submissions` | 学情数据投递 |
|
||||||
|
| 消费 | core-edu（CDC） | Kafka | `edu-cdc.next_edu_cloud.classes` | 班级维度同步 |
|
||||||
|
| 消费 | iam（CDC） | Kafka | `edu-cdc.next_edu_cloud.iam_users` | 用户 dataScope 同步 |
|
||||||
|
| 消费 | ai | Kafka | `edu.insight.ai.usage`（**待 coord 新增**） | AI 用量落库 |
|
||||||
|
| 发布 | — | Kafka | `edu.insight.mastery.updated` | 掌握度更新通知 core-edu / msg |
|
||||||
|
|
||||||
|
## 8. 风险与假设
|
||||||
|
|
||||||
|
### 8.1 假设
|
||||||
|
|
||||||
|
- **假设 1**：iam 提供 `GetEffectiveDataScope(userId) → DataScope` gRPC API。若 iam 未提供，fallback 为：从 `x-user-roles` 头推导（admin=ALL, teacher=CLASS_TAUGHT, student=SELF），但无法支持细粒度年级/学校范围
|
||||||
|
- **假设 2**：core-edu 的 `core_edu_homework_submissions` 表存在 binlog。若不存在，作业相关学情无法通过 CDC 获取，需 core-edu 补表或走 Outbox 事件
|
||||||
|
- **假设 3**：ClickHouse `ReplacingMergeTree` 在查询时需 `FINAL` 关键字确保去重生效。当前查询未加 `FINAL`，可能读到重复版本。**修复**：所有查询加 `FINAL` 或使用 `argMax` 聚合
|
||||||
|
- **假设 4**：coord 同意新增 `edu.insight.ai.usage` topic。若不同意，ai 服务的用量计费需自建记录（破坏 ai 无状态原则）
|
||||||
|
|
||||||
|
### 8.2 技术风险
|
||||||
|
|
||||||
|
| 风险 | 影响 | 缓解措施 |
|
||||||
|
| --------------------------- | ------------------------------------ | ------------------------------------------------ |
|
||||||
|
| ClickHouse 查询延迟超 5s | 违反 P4 退出标准 | 宽表索引优化 + 物化视图预聚合 + 查询超时 3s 降级 |
|
||||||
|
| CDC 消费者 lag 过大 | 学情数据延迟 > 5s | 监控 lag + 告警 + 水平扩展消费者（分区数提升） |
|
||||||
|
| ExamCache 内存泄漏 | 长期运行 OOM | LRU 淘汰策略（max 10000 条）+ 定期清理过期 exam |
|
||||||
|
| mastery.updated 事件丢失 | 下游 core-edu/msg 收不到通知 | Kafka producer `acks=all` + 本地失败表重试 |
|
||||||
|
| iam gRPC 不可达 | DataScope 无法解析 → 查询降级为 SELF | Redis 缓存 5min + fallback SELF 范围（最保守） |
|
||||||
|
| ClickHouse `FINAL` 查询性能 | 查询变慢 | 使用 `argMax` 替代 `FINAL`，或在写入时去重 |
|
||||||
|
|
||||||
|
### 8.3 未决设计决策（需 coord 仲裁）
|
||||||
|
|
||||||
|
1. **mastery.updated 发布是否需要 Outbox**：Python 无 Outbox 模式，建议直接 producer；但 004 §12.2 明确"事件发布：Outbox 模式 / 禁止直接 Kafka producer"。**冲突**：data-ana 是 Python 服务无 MySQL 写事务，Outbox 不适用。建议 coord 裁定：派生数据事件（非业务事务）允许直接 producer
|
||||||
|
2. **iam GetEffectiveDataScope proto 新增**：当前 iam.proto 仅有 `GetUserInfo`，无 DataScope 解析 API。需 coord 在 shared-proto 新增 `GetEffectiveDataScope` RPC
|
||||||
|
3. **edu.insight.ai.usage topic 新增**：004 §7.2 未列出，需 coord 确认是否新增

|
||||||
|
|
||||||
|
**分层规则**：
|
||||||
|
|
||||||
|
- **入口层**：HTTP（保留作 Gateway 直连）+ gRPC（主入口，含 `StreamChat` 流式 RPC）
|
||||||
|
- **中间件层**：Auth + RateLimit（Redis 令牌桶，按 user_id 限流）
|
||||||
|
- **应用服务层**：4 个 Service，每个对应一类 AI 能力
|
||||||
|
- **Provider 适配层**：抽象 `LLMProvider` 接口，多适配器实现（策略模式）
|
||||||
|
- **Prompt 模板**：模板注册 + 渲染，模板存储可配置（YAML 文件 or DB）
|
||||||
|
- **下游 client**：gRPC 调 content / data-ana
|
||||||
|
- **用量计费**：token 消耗统计 + Kafka 事件外发
|
||||||
|
|
||||||
|
## 2. 领域模型
|
||||||
|
|
||||||
|
ai 是**无状态服务**，不持有持久化聚合根。领域模型为**请求/响应模型 + 工作流编排**：
|
||||||
|
|
||||||
|
### 聚合根（请求型，无持久化）
|
||||||
|
|
||||||
|
| 聚合根 | 含义 | 生命周期 |
|
||||||
|
| ---------------------------- | ------------ | ------------------------------------------------------------ |
|
||||||
|
| `ChatConversation` | 单次聊天请求 | 单次请求 |
|
||||||
|
| `QuestionGenerationTask` | 出题任务 | 单次请求（备课工作流中多步） |
|
||||||
|
| `ExpressionOptimizationTask` | 表达优化任务 | 单次请求 |
|
||||||
|
| `LessonPreparationWorkflow` | 备课工作流 | 跨多步（分析学情 → 推荐知识点 → 生成题目 → 教师审核 → 入库） |
|
||||||
|
|
||||||
|
### 值对象
|
||||||
|
|
||||||
|
- `ChatMessage`：role + content
|
||||||
|
- `Usage`：prompt_tokens + completion_tokens + total_tokens
|
||||||
|
- `GeneratedQuestion`：question + answer + explanation
|
||||||
|
- `PromptTemplate`：name + system_prompt + user_template + variables
|
||||||
|
|
||||||
|
### 工作流编排（备课）
|
||||||
|
|
||||||
|
```mermaid
|
||||||
|
sequenceDiagram
|
||||||
|
participant T as 教师
|
||||||
|
participant BFF as teacher-bff
|
||||||
|
participant AI as ai 服务
|
||||||
|
participant Content as content
|
||||||
|
participant DA as data-ana
|
||||||
|
|
||||||
|
T->>BFF: 请求备课（class_id, subject_id）
|
||||||
|
BFF->>AI: gRPC GenerateLessonPlan
|
||||||
|
AI->>DA: gRPC GetStudentWeakness(class_id)
|
||||||
|
DA-->>AI: 薄弱知识点列表
|
||||||
|
AI->>Content: gRPC GetPrerequisites(knowledge_point_id)
|
||||||
|
Content-->>AI: 前置依赖知识点
|
||||||
|
AI->>AI: LLM 生成题目（基于学情 + 知识点）
|
||||||
|
AI-->>BFF: 题目列表 + 推荐理由
|
||||||
|
BFF-->>T: 题目供审核
|
||||||
|
T->>BFF: 确认入库
|
||||||
|
BFF->>Content: gRPC CreateQuestions
|
||||||
|
Content-->>BFF: 入库成功
|
||||||
|
```
|
||||||
|
|
||||||
|
**工作流实现**：
|
||||||
|
|
||||||
|
- **简单场景**（4 步内）：FastAPI BackgroundTasks + asyncio.gather 并行查询
|
||||||
|
- **复杂场景**（含教师审核等待）：待 coord 仲裁是否引入 Temporal（004 §2.3 列出 Temporal 用于 AI 编排）
|
||||||
|
|
||||||
|
## 3. 数据模型
|
||||||
|
|
||||||
|
ai 服务**无独占数据库**，无 MySQL schema。所有数据通过 Kafka 事件外发（用量计费）或 gRPC 查询下游。
|
||||||
|
|
||||||
|
### 用量计费（Kafka 事件 → data-ana 落 ClickHouse）
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"event_id": "uuid",
|
||||||
|
"user_id": "user-xxx",
|
||||||
|
"request_id": "req-xxx",
|
||||||
|
"provider": "openai",
|
||||||
|
"model": "gpt-4o-mini",
|
||||||
|
"prompt_tokens": 150,
|
||||||
|
"completion_tokens": 80,
|
||||||
|
"total_tokens": 230,
|
||||||
|
"latency_ms": 1200,
|
||||||
|
"success": true,
|
||||||
|
"occurred_at": "2026-07-09T12:00:00Z"
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Topic**：`edu.insight.ai.usage`（**待 coord 新增**）
|
||||||
|
|
||||||
|
### 缓存策略
|
||||||
|
|
||||||
|
| 数据 | 存储 | TTL | 失效策略 |
|
||||||
|
| -------------------------------------- | ----------------------------- | -------- | ---------------------- |
|
||||||
|
| Prompt 模板 | Redis（模板变更事件驱动失效） | 1 小时 | 文件/DB 变更时主动失效 |
|
||||||
|
| LLM 响应（相同 prompt） | Redis（hash 缓存） | 30 分钟 | 短 TTL，避免陈旧 |
|
||||||
|
| DataScope（ai 不需要，仅 data-ana 用） | — | — | — |
|
||||||
|
| 限流计数 | Redis 令牌桶 | 滑动窗口 | 自动过期 |
|
||||||
|
|
||||||
|
## 4. API 设计
|
||||||
|
|
||||||
|
### 4.1 HTTP 端点（保留作 Gateway 直连降级）
|
||||||
|
|
||||||
|
| method | path | 权限 | 请求体 | 响应 | 说明 |
|
||||||
|
| ------ | ------------------------- | ------------------------ | --------------------------- | ------------------------------------ | ---------------------- |
|
||||||
|
| GET | `/healthz` | — | — | `{status, service}` | liveness |
|
||||||
|
| GET | `/readyz` | — | — | `{status, llm_configured, degraded}` | readiness |
|
||||||
|
| GET | `/metrics` | — | — | Prometheus | 指标 |
|
||||||
|
| POST | `/ai/chat` | `AI_CHAT` | `ChatRequest` | `ChatResponse` | LLM 聊天 |
|
||||||
|
| POST | `/ai/chat/stream` | `AI_CHAT` | `ChatRequest` | SSE stream | 流式聊天 |
|
||||||
|
| POST | `/ai/generate/question` | `AI_QUESTION_GENERATE` | `GenerateQuestionRequest` | `GeneratedQuestionResponse` | 生成题目 |
|
||||||
|
| POST | `/ai/optimize/expression` | `AI_EXPRESSION_OPTIMIZE` | `OptimizeExpressionRequest` | `OptimizedExpressionResponse` | 优化表达 |
|
||||||
|
| POST | `/ai/lesson/preparation` | `AI_LESSON_PREPARE` | `LessonPreparationRequest` | `LessonPreparationResponse` | 备课工作流（**新增**） |
|
||||||
|
|
||||||
|
### 4.2 gRPC 契约（ai.proto，待实现 server）
|
||||||
|
|
||||||
|
| RPC | 请求 | 响应 | 权限 | 说明 |
|
||||||
|
| -------------------- | ------------------------------------------------------ | ------------------------------------- | ------------------------ | ------------------------- |
|
||||||
|
| `Chat` | `ChatRequest{messages, model, temperature}` | `ChatResponse{content, model, usage}` | `AI_CHAT` | 非流式聊天 |
|
||||||
|
| `StreamChat` | `ChatRequest` | `stream ChatChunk` | `AI_CHAT` | 流式聊天（SSE over gRPC） |
|
||||||
|
| `GenerateQuestion` | `GenerateQuestionRequest{prompt, subject, difficulty}` | `GeneratedQuestion` | `AI_QUESTION_GENERATE` | 生成题目 |
|
||||||
|
| `OptimizeExpression` | `OptimizeExpressionRequest{text, context}` | `OptimizedExpression` | `AI_EXPRESSION_OPTIMIZE` | 优化表达 |
|
||||||
|
|
||||||
|
### 4.3 Pydantic 请求/响应模型
|
||||||
|
|
||||||
|
```python
|
||||||
|
class ChatRequest(BaseModel):
|
||||||
|
messages: list[ChatMessage]
|
||||||
|
model: str = "gpt-4o-mini"
|
||||||
|
temperature: float = Field(0.7, ge=0.0, le=2.0)
|
||||||
|
stream: bool = False
|
||||||
|
|
||||||
|
class ChatMessage(BaseModel):
|
||||||
|
role: Literal["system", "user", "assistant"]
|
||||||
|
content: str
|
||||||
|
|
||||||
|
class ChatResponse(BaseModel):
|
||||||
|
success: bool
|
||||||
|
data: ChatData
|
||||||
|
degraded: bool = False
|
||||||
|
|
||||||
|
class ChatData(BaseModel):
|
||||||
|
content: str
|
||||||
|
model: str
|
||||||
|
usage: Usage
|
||||||
|
|
||||||
|
class Usage(BaseModel):
|
||||||
|
prompt_tokens: int
|
||||||
|
completion_tokens: int
|
||||||
|
total_tokens: int
|
||||||
|
|
||||||
|
class GenerateQuestionRequest(BaseModel):
|
||||||
|
prompt: str = Field(..., min_length=1, max_length=2000)
|
||||||
|
subject: str
|
||||||
|
difficulty: Literal["easy", "medium", "hard"]
|
||||||
|
knowledge_point_ids: list[str] = [] # 可选：靶向知识点
|
||||||
|
|
||||||
|
class GeneratedQuestionResponse(BaseModel):
|
||||||
|
success: bool
|
||||||
|
data: GeneratedQuestionData
|
||||||
|
degraded: bool = False
|
||||||
|
```
|
||||||
|
|
||||||
|
## 5. 事件设计
|
||||||
|
|
||||||
|
### 5.1 消费的事件
|
||||||
|
|
||||||
|
ai 服务**不消费任何事件**（无状态，纯请求-响应）。
|
||||||
|
|
||||||
|
### 5.2 发布的事件
|
||||||
|
|
||||||
|
| 事件 | Topic | 触发时机 | 消费者 | Payload |
|
||||||
|
| ----------------- | ------------------------------------------- | ----------------- | -------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------ |
|
||||||
|
| `AIUsageRecorded` | `edu.insight.ai.usage`（**待 coord 新增**） | 每次 LLM 调用完成 | data-ana（落 ClickHouse ai_usage_log） | `{event_id, user_id, request_id, provider, model, prompt_tokens, completion_tokens, total_tokens, latency_ms, success, occurred_at}` |
|
||||||
|
|
||||||
|
**发布实现**：
|
||||||
|
|
||||||
|
- 每次 LLM 调用后异步发布（不阻塞响应）
|
||||||
|
- `aiokafka.AIOKafkaProducer` + `acks=all`
|
||||||
|
- 失败重试 3 次，仍失败记录日志（不影响主流程）
|
||||||
|
|
||||||
|
## 6. 横切关注点对齐清单
|
||||||
|
|
||||||
|
### 6.1 权限装饰器等价物
|
||||||
|
|
||||||
|
```python
|
||||||
|
class Permissions:
|
||||||
|
AI_CHAT = "ai:chat"
|
||||||
|
AI_QUESTION_GENERATE = "ai:question:generate"
|
||||||
|
AI_EXPRESSION_OPTIMIZE = "ai:expression:optimize"
|
||||||
|
AI_LESSON_PREPARE = "ai:lesson:prepare"
|
||||||
|
|
||||||
|
async def require_permission(permission: str) -> UserContext:
|
||||||
|
"""从 x-user-id / x-user-roles 校验权限."""
|
||||||
|
...
|
||||||
|
```
|
||||||
|
|
||||||
|
### 6.2 错误码清单（前缀 `AI_*`）
|
||||||
|
|
||||||
|
| 错误码 | 触发条件 | HTTP | gRPC status |
|
||||||
|
| --------------------------- | ----------------------------------------- | ------------------- | ------------------ |
|
||||||
|
| `AI_UNAUTHORIZED` | 缺失 x-user-id 或 token 无效 | 401 | UNAUTHENTICATED |
|
||||||
|
| `AI_FORBIDDEN` | 角色无对应权限 | 403 | PERMISSION_DENIED |
|
||||||
|
| `AI_RATE_LIMITED` | 触发限流 | 429 | RESOURCE_EXHAUSTED |
|
||||||
|
| `AI_LLM_UNAVAILABLE` | LLM Provider 不可达（降级模式仍返回骨架） | 200 + degraded:true | OK + degraded flag |
|
||||||
|
| `AI_LLM_TIMEOUT` | LLM 调用超时（30s） | 504 | DEADLINE_EXCEEDED |
|
||||||
|
| `AI_INVALID_MODEL` | model 名不支持 | 400 | INVALID_ARGUMENT |
|
||||||
|
| `AI_INVALID_DIFFICULTY` | difficulty 不在 easy/medium/hard | 400 | INVALID_ARGUMENT |
|
||||||
|
| `AI_DOWNSTREAM_UNAVAILABLE` | content / data-ana gRPC 不可达 | 502 | UNAVAILABLE |
|
||||||
|
| `AI_PROMPT_RENDER_FAILED` | Prompt 模板渲染失败（变量缺失） | 500 | INTERNAL |
|
||||||
|
| `AI_INTERNAL_ERROR` | 未捕获异常 | 500 | INTERNAL |
|
||||||
|
|
||||||
|
### 6.3 Logger 初始化
|
||||||
|
|
||||||
|
- 位置：`main.py`（已具备）
|
||||||
|
- **改进**：生产环境改用 `JSONRenderer`
|
||||||
|
|
||||||
|
### 6.4 Metrics 指标清单
|
||||||
|
|
||||||
|
| 指标名 | 类型 | 标签 | 描述 |
|
||||||
|
| ---------------------------------- | --------- | ----------------------------------------- | ------------------ |
|
||||||
|
| `ai_http_requests_total` | Counter | method, path, status | HTTP 请求总数 |
|
||||||
|
| `ai_http_request_duration_seconds` | Histogram | method, path | HTTP 请求延迟 |
|
||||||
|
| `ai_llm_calls_total` | Counter | provider, model, status | LLM 调用总数 |

|
||||||
|
|
||||||
|
### 6.5 Tracer 初始化
|
||||||
|
|
||||||
|
- 位置：`main.py` `init_tracer()`（已具备，dev_mode 跳过）
|
||||||
|
- **改进**：gRPC server interceptor + 下游 gRPC client interceptor 透传 trace context
|
||||||
|
|
||||||
|
### 6.6 /healthz 检查逻辑
|
||||||
|
|
||||||
|
- liveness：仅进程存活（已具备）
|
||||||
|
|
||||||
|
### 6.7 /readyz 检查逻辑
|
||||||
|
|
||||||
|
```python
|
||||||
|
async def readyz() -> dict:
|
||||||
|
return {
|
||||||
|
"status": "ok",
|
||||||
|
"service": "ai",
|

```
|
||||||
|

|
### 6.8 优雅关闭顺序
|
||||||
|
|
||||||
|
1. HTTP server stop accepting new requests
|
||||||
|
2. gRPC server graceful stop（**关键**：等待在途 `StreamChat` 流式 RPC 完成，60s 超时，避免截断用户响应）
|
||||||
|
3. LLM 流式请求 drain（等待 httpx stream 完成）
|
||||||
|
4. Kafka producer flush + close（确保用量事件已投递）
|
||||||
|
5. 下游 gRPC channels close（content / data-ana）
|
||||||
|
6. Redis connection close
|
||||||
|
|
||||||
|
## 7. 与其他模块的交互点（契约清单）
|
||||||
|
|
||||||
|
| 方向 | 对方服务 | 协议 | 接口/事件 | 用途 |
|
||||||
|
| ------ | ------------ | ----- | ---------------------------------------------------------- | ------------------ |
|
||||||
|
| 被调用 | api-gateway | HTTP | `/ai/*` | Gateway 代理 |
|
||||||
|
| 被调用 | teacher-bff | gRPC | `AiService.*` | BFF 聚合 AI 能力 |
|
||||||
|
| 调用 | content | gRPC | `KnowledgeGraphService.GetPrerequisites / GetLearningPath` | 出题上下文查询 |
|
||||||
|
| 调用 | content | gRPC | `TextbookService.*`（若需教材上下文） | 出题教材关联 |
|
||||||
|
| 调用 | data-ana | gRPC | `AnalyticsService.GetStudentWeakness / GetLearningTrend` | 个性化出题学情查询 |
|
||||||
|
| 调用 | LLM Provider | HTTP | OpenAI 兼容 REST `/chat/completions` | LLM 推理 |
|
||||||
|
| 发布 | — | Kafka | `edu.insight.ai.usage`（**待 coord 新增**） | 用量计费外发 |
|
||||||
|
|
||||||
|
## 8. 风险与假设
|
||||||
|
|
||||||
|
### 8.1 假设
|
||||||
|
|
||||||
|
- **假设 1**：content 服务实现了 `KnowledgeGraphService` gRPC server。当前 content.proto 已定义但未实现 gRPC server（ai05 阶段 2 设计中）。ai 调用前需确认 content gRPC 可用
|
||||||
|
- **假设 2**：data-ana 实现了 `AnalyticsService` gRPC server（本设计文档已设计）。ai 调用前需确认 data-ana gRPC 可用
|
||||||
|
- **假设 3**：coord 同意新增 `edu.insight.ai.usage` topic。若不同意，用量计费降级为 ai 本地日志（不落 ClickHouse，影响成本分析）
|
||||||
|
- **假设 4**：Redis 可用（限流依赖）。若 Redis 不可用，限流降级为"无限制"（风险：LLM 成本失控），或降级为内存令牌桶（单实例有效，多实例不一致）
|
||||||
|
|
||||||
|
### 8.2 技术风险
|
||||||
|
|
||||||
|
| 风险 | 影响 | 缓解措施 |
|
||||||
|
| ---------------------- | ---------------- | --------------------------------------------------------------- |
|
||||||
|
| LLM 调用延迟高（>30s） | 用户体验差 | 超时 30s + 降级骨架响应 + 流式优先（用户感知首字延迟） |
|
||||||
|
| LLM 成本失控 | 财务风险 | Redis 令牌桶限流（每用户每分钟 10 次）+ 用量计费监控 + 告警阈值 |
|
||||||
|
| LLM Provider 单点故障 | 服务不可用 | 多 Provider 适配器 + 自动 failover（OpenAI 失败切 Anthropic） |
|
||||||
|
| 流式 RPC 中断 | 用户响应截断 | gRPC server graceful shutdown 60s drain + 客户端重连机制 |
|
||||||
|
| Prompt 注入攻击 | LLM 输出恶意内容 | 输入 sanitize + system prompt 加安全约束 + 输出过滤 |
|
||||||
|
| 下游 gRPC 不可达 | 备课工作流失败 | 降级：跳过学情查询，仅基于 prompt 生成题目 + `degraded: true` |
|
||||||
|
|
||||||
|
### 8.3 未决设计决策（需 coord 仲裁）
|
||||||
|
|
||||||
|
1. **备课工作流是否引入 Temporal**：004 §2.3 列出 Temporal 用于 AI 编排，但简单 4 步工作流可用 FastAPI BackgroundTasks。建议：M14 用 BackgroundTasks，M15 评估是否迁移 Temporal
|
||||||
|
2. **`edu.insight.ai.usage` topic 新增**：需 coord 在 shared-proto events.proto 新增 `AIUsageEvent` message + 004 §7.2 新增 topic
|
||||||
|
3. **LLM Provider 配置化路由**：是否在 shared-py 建立通用 `LLMProvider` 抽象（供未来其他 Python 服务复用）。建议 P5 阶段在 ai 服务内部实现，P6 评估是否提取到 shared-py
|
||||||
|
4. **Prompt 模板存储位置**：YAML 文件（简单，无 DB）vs DB（动态更新）。建议 P5 用 YAML 文件（`services/ai/src/ai/prompts/*.yaml`），P6 评估迁移 DB

# 阶段 2 总结
|
||||||
|
|
||||||
|
ai06 已完成阶段 2 模块架构设计，产出 data-ana 与 ai 两份设计文档。核心设计决策：
|
||||||
|
|
||||||
|
## data-ana 设计要点
|
||||||
|
|
||||||
|
1. **分层**：HTTP + gRPC 双入口共享 Application Service；CDC 消费者独立后台任务
|
||||||
|
2. **数据模型**：4 张 ClickHouse 宽表（student_dashboard_view / student_errors / mastery_snapshot / ai_usage_log），ReplacingMergeTree 引擎保证幂等
|
||||||
|
3. **权限**：FastAPI Depends 链（require_permission + inject_data_scope），DataScope WHERE 注入 ClickHouse 查询
|
||||||
|
4. **事件**：消费 6 个 CDC topic + 发布 `edu.insight.mastery.updated`（直接 producer，非 Outbox，因派生数据非事务写）
|
||||||
|
5. **gRPC**：实现 `AnalyticsService` server（analytics.proto 已定义）
|
||||||
|
6. **降级**：ClickHouse 不可达返回骨架 + degraded:true；iam gRPC 不可达降级为 SELF DataScope
|
||||||
|
|
||||||
|
## ai 设计要点
|
||||||
|
|
||||||
|
1. **分层**：HTTP + gRPC 双入口；LLM Provider 适配层（策略模式，4 适配器）
|
||||||
|
2. **无状态**：无 DB，用量计费通过 Kafka 事件外发
|
||||||
|
3. **权限**：FastAPI Depends + Redis 令牌桶限流（每用户每分钟 10 次）
|
||||||
|
4. **工作流**：备课 4 步编排（学情查询 → 知识点推荐 → 题目生成 → 教师审核入库），简单场景用 BackgroundTasks
|
||||||
|
5. **gRPC**：实现 `AiService` server（含 `StreamChat` 流式 RPC）；gRPC client 调 content / data-ana
|
||||||
|
6. **降级**：LLM 不可达返回骨架 + degraded:true；下游 gRPC 不可达降级跳过
|
||||||
|

||||||

## 2. 模块分工矩阵
|
## 2. 两种协作模式
|
||||||
|
|
||||||
### 2.1 模块清单与 AI 分配
|
本项目支持两种 AI 协作模式，根据开发阶段灵活切换：
|
||||||
|
|
||||||
每个 AI 负责一个"限界上下文"，避免跨模块修改导致冲突。
|
### 2.0 模式选择
|
||||||
|
|
||||||
| 模块 | scope | 路径 | 负责阶段 | 建议 AI 数 |
|
| 模式 | 适用阶段 | 特点 |
|
||||||
| -------------- | ---------------- | ------------------------- | -------- | ------------ |
|
| ------------------ | ---------------------------------- | ----------------------------------------------------- |
|
||||||
| api-gateway | `api-gateway` | `services/api-gateway/` | P1 | 1 |
|
| **单仓库并行模式** | 架构设计外包、各服务独立功能开发 | 无需 PR，直接 push main；路径级别物理隔离，几乎零冲突 |
|
||||||
| classes | `classes` | `services/classes/` | P1 | 1 |
|
| **PR 模式** | 共享文件修改、跨模块变更、代码审核 | 标准 PR 流程，coord 审核后 Squash Merge |
|
||||||
| teacher-portal | `teacher-portal` | `apps/teacher-portal/` | P1-P2 | 1 |
|
|
||||||
| iam | `iam` | `services/iam/` | P2 | 1 |
|
|
||||||
| teacher-bff | `teacher-bff` | `services/teacher-bff/` | P2 | 1 |
|
|
||||||
| core-edu | `core-edu` | `services/core-edu/` | P3 | 1 |
|
|
||||||
| content | `content` | `services/content/` | P4 | 1 |
|
|
||||||
| data-ana | `data-ana` | `services/data-ana/` | P4 | 1 |
|

|
|
||||||
| ai | `ai` | `services/ai/` | P5 | 1 |
|
|
||||||
| push-gateway | `push-gateway` | `services/push-gateway/` | P5 | 1 |
|
|
||||||
| shared-proto | `shared-proto` | `packages/shared-proto/` | 跨阶段 | 协调 AI 维护 |
|
|
||||||
| shared-tokens | `shared-tokens` | `packages/shared-tokens/` | 跨阶段 | 协调 AI 维护 |
|
|
||||||
| infra | `infra` | `infra/` | 跨阶段 | 1 (SRE AI) |
|
|
||||||
| docs | `docs` | `docs/` | 跨阶段 | 协调 AI 维护 |
|
|
||||||
|
|
||||||
### 2.2 分工原则
|
> 当前架构设计外包阶段使用**单仓库并行模式**，详见 [AI 分配方案](../architecture/ai-allocation.md)。
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### 2.1 单仓库并行模式
|
||||||
|
|
||||||
|
**适用场景**：各 AI 修改的文件路径物理隔离（不同 `services/<name>/` 目录），无需 PR 审核。
|
||||||
|
|
||||||
|
**核心规则**：
|
||||||
|
|
||||||
|
1. 每个 AI 只能修改自己负责的目录
|
||||||
|
2. `pnpm-lock.yaml` 是唯一可能冲突的共享文件，冲突时取远程版本后 `pnpm install` 重新生成
|
||||||
|
3. proto 变更由 coord 统一管理（其他 AI 只读引用 `packages/shared-proto/`）
|
||||||
|
|
||||||
|
**提交流程**：
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# 每天开始
|
||||||
|
git pull origin main --rebase
|
||||||
|
|
||||||
|
# 在自己目录内工作后提交
|
||||||
|
git add services/<my-service>/...
|
||||||
|
git commit -m "feat(<scope>): <描述>"
|
||||||
|
|
||||||
|
# 直接 push
|
||||||
|
git pull origin main --rebase # 先拉最新
|
||||||
|
git push
|
||||||
|
```
|
||||||
|
|
||||||
|
**pnpm-lock.yaml 冲突处理**：
|
||||||
|
|
||||||
|
```bash
|
||||||
|
git pull origin main --rebase
|
||||||
|
# 若 pnpm-lock.yaml 冲突：
|
||||||
|
git checkout --theirs pnpm-lock.yaml
|
||||||
|
pnpm install
|
||||||
|
git add pnpm-lock.yaml
|
||||||
|
git rebase --continue
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### 2.2 PR 模式（标准流程）
|
||||||
|
|
||||||
|
PR 模式见 §3-§6（分支策略、推送流程、PR 流程、审核合并）。

### 2.5 分工原则
|
||||||
|
|
||||||
1. **单一负责制**：每个模块只有一个 AI 负责，避免并行修改同一文件
|
1. **单一负责制**：每个模块只有一个 AI 负责，避免并行修改同一文件
|
||||||
2. **契约集中管理**：`shared-proto` 由协调 AI 维护，开发 AI 只读引用
|
2. **同语言内聚**：一个 AI 负责多个同语言服务，降低学习成本
|
||||||
3. **跨模块变更拆分**：需要修改多个模块时，拆成多个 PR，按依赖顺序合并
|
3. **契约集中管理**：`shared-proto` 由 coord 维护，开发 AI 只读引用
|
||||||
4. **基础设施独立**：`infra/` 由 SRE AI 专门负责，业务 AI 不直接修改
|
4. **跨模块变更拆分**：需要修改多个模块时，按依赖顺序（proto → service → gateway → BFF → frontend）
|
||||||
|
5. **基础设施独立**：`infra/` 由 coord（或 SRE AI）专门负责
|
||||||
|
6. **物理路径隔离**：目录级别隔离，单仓库并行几乎零文件冲突
|
||||||
|
|
||||||
|
### 2.6 架构设计外包三阶段
|
||||||
|
|
||||||
|
当前项目处于**架构设计外包阶段**，所有 AI 需先完成设计再动手写代码。完整文档见 [AI 分配方案](../architecture/ai-allocation.md)。简述如下：
|
||||||
|
|
||||||
|
```
|
||||||
|
阶段 1：全局理解 → 交付"理解确认书"
|
||||||
|
阶段 2：模块架构设计 → 交付"模块架构设计文档"，coord 交叉审查
|
||||||
|
阶段 3：按图实施 → 按设计文档写代码，coord 定期巡检一致性
|
||||||
|
```
|
||||||
|
|
||||||
|

| 2026-07-09 | 下午 | 全局 | **P6 硬化：可观测性 + 部署 + CI 硬化**：(1) 可观测性栈完善：5 个 NestJS 服务 main.ts 添加 `/metrics` Prometheus 端点（用 `app.getHttpAdapter().get('/metrics', ...)` 绕过 DI 容器 get 方法）；prometheus.yml 从 2 个目标扩展到 8 个应用服务 + MySQL/Redis + node-exporter + prometheus 自身 + rule_files + alertmanager 关联；monitoring compose 用 Loki + Promtail 替换未配置的 blackbox-exporter；Grafana datasource 新增 Loki；新建 promtail/config.yml 用 docker_sd_configs 仅采集 `edu-*` 容器日志。(2) 部署 compose 扩展：docker-compose.deploy.yml 从 3 服务扩展到 11 服务（+ iam/teacher-bff/core-edu/content/msg/ai/data-ana/push-gateway），每个服务带 healthcheck + depends_on 条件 + edu-net/edu-shared 双网络；deploy.env.example 补全 Neo4j/ES/ClickHouse/LLM/Kafka 可选依赖配置。(3) teacher-bff 补 health.controller.ts（原缺失 /healthz 导致 deploy depends_on service_healthy 失败）。(4) CI 硬化：移除 lint 步骤的 continue-on-error（ESLint 9 flat config 已配置完成），test 保留 continue-on-error（部分服务无 test 脚本）。**学到**：NestJS `app.get('/metrics')` 会被解析为 DI 容器 `get(typeOrToken)`，必须用 `app.getHttpAdapter().get()` 才能注册 Express 路由；Promtail docker_sd_configs 通过 relabel_configs 的 `regex: '/(edu-.*).*'` 过滤容器名前缀；docker-compose.depends_on.condition: service_healthy 要求被依赖服务必须有 healthcheck 配置，否则启动失败。 |

| 2026-07-09 | 下午 | classes/全局 | **一键启动脚本 NestJS dist/ 不生成根因定位 + classes 健康检查修复**：(1) 根因定位：`tsconfig.base.json` 的 `incremental: true` + `nest-cli.json` 的 `deleteOutDir: true` 冲突。`nest start --watch` 启动时先删除 dist/，tsc 读残留 .tsbuildinfo 认为无变化跳过 emit，dist/ 不生成 → `Cannot find module dist/main`。(2) 修复：6 个 NestJS 服务（classes/iam/teacher-bff/core-edu/content/msg）tsconfig.json 显式加 `"incremental": false` 覆盖 base 配置，删除所有残留 .tsbuildinfo 文件。(3) classes AppModule 缺 HealthModule 导入导致 /healthz 404，iam 同样问题，修复 app.module.ts 加 `imports: [..., HealthModule]`。(4) classes HealthController 误用 TypeORM `DataSource` DI（与 iam 不一致），运行时报 `Nest can't resolve dependencies of the HealthController (DataSource)`。修复：改为 Drizzle `getDb()` 函数式调用，与 iam 一致。(5) 一键启动验证：11/11 应用 + 11/11 基础设施 + 5/5 可观测性端点全绿。**学到**：NestJS + TypeScript incremental 编译是陷阱组合——nest-cli deleteOutDir 删 dist 但 tsc 读 tsbuildinfo 认为无变化，必须在服务级 tsconfig 显式 `incremental: false`；HealthModule 必须在 AppModule imports 中显式声明才能被 NestFactory 扫描到；5 个 NestJS 服务的 HealthController 应统一用 Drizzle `getDb()` 函数式调用而非 TypeORM DataSource DI（项目已弃 TypeORM 改 Drizzle）。 |

| 2026-07-08 | 下午 | api-gateway | **重定向循环修复 + 生产模式部署准备 + 多AI协作文档**：(1) 修复 `ERR_TOO_MANY_REDIRECTS`：Gin 默认 `RedirectTrailingSlash=true` 导致 `/api/v1/classes` → 301 → `/classes/`，Next.js rewrites 代理时形成循环。**修复**：`r.RedirectTrailingSlash=false` + 同时注册无尾斜杠路由（`/classes`）与通配符路由（`/classes/*path`）。(2) 新增 DEV_MODE 旁路：`config.go` 加 `DevMode` 字段，`auth.go` 在 `DEV_MODE=true` 时接受 `dev-token` 注入固定身份（生产必须 false）。(3) 生产 Docker 化：新建 `apps/teacher-portal/Dockerfile`（多阶段 Next.js build）+ `services/api-gateway/Dockerfile`（多阶段 Go 静态编译）+ `infra/docker-compose.prod.yml`（三服务编排，强制 DEV_MODE=false）。(4) 编写 `docs/standards/local-dev-runbook.md`（本地启动手册，含端口表/开发模式/生产模式/常见问题）+ `docs/standards/multi-ai-collaboration.md`（多AI协作文档，含模块分工矩阵/分支命名/PR流程/合并策略/冲突处理/权限矩阵）。**学到**：Gin `RedirectTrailingSlash=false` 后需显式注册无尾斜杠路由（`Any("/classes")` + `Any("/classes/*path")`），否则 404；Next.js rewrites 代理会透传 301 给浏览器形成循环，开发模式旁路应通过环境变量控制而非硬编码。 |

| 2026-07-08 | 晚上 | iam/classes/api-gateway | **P1 端到端链路验证 + IAM 服务修复**：验证 register → JWT → Gateway /iam/me → Gateway /classes CRUD → teacher-portal 前端渲染全链路打通。(1) IAM 服务 14 个 TS 编译错误修复：移除 typeorm/ioredis/kafkajs 依赖（IAM 用 Drizzle），health.controller.ts 改用 `db.execute(sql\`SELECT 1\`)`，lifecycle.service.ts 简化为只关闭 Drizzle 连接池；Drizzle API 修正（`r.roles`→`r.iam_roles`，`.in()`→`inArray()`）。(2) NestJS ESM DI 修复：iam.module.ts 简化 providers 为 `[IamService, IamRepository]`，iam.service.ts 构造器加 `@Inject(IamRepository)`（参考 classes 黄金模板），修复运行时 `Cannot read properties of undefined (reading 'findUserByEmail')`。(3) Gateway /iam/me 404 修复：iam.controller.ts 直接读 `req.headers['x-user-id']`替代未注册的`AuthenticatedRequest`。(4) 创建 `scripts/iam-init.sql`建 6 张 IAM 表 + 种子数据。(5) E2E 验证：iam:3002 注册/登录 → Gateway /iam/me 200 → Gateway GET /classes 200 → Gateway POST /classes（合法 UUID gradeId）201 → teacher-portal:3000 首页渲染 200 + 含"班级管理" → Next.js rewrites 透传 dev-token 到 Gateway 全链路通。**学到**：NestJS ESM 模式下 DI 无法通过类型推断解析 token，必须显式`@Inject(Token)`；Drizzle select 返回字段名按 schema 定义而非表名；classes.dto.ts 的 gradeId 要求 UUID 格式，测试数据不能用 "grade-12" 这类字符串；PowerShell 控制台中文显示为 `?`是编码问题，数据库实际存储正确；DEV_MODE 下前端用`Bearer dev-token` 即可走通链路，无需真实 JWT。 |

|
| 2026-07-08 | 下午 | 全局 | **CI/CD 完整配置 + 多AI协作规范入规则**：(1) project_rules.md 新增 §14 多 AI 协作规范（角色权限矩阵/分支命名/PR合并规则/跨模块变更顺序/冲突处理/AI 身份标注/敏感文件保护）+ §15 CI/CD 规范（流水线阶段/触发条件/镜像规范/部署策略/Secrets 管理/必需 CI 文件）。(2) 优化现有 4 个 ci-*.yml：ci-ts.yml 加 arch-scan + docker-build job；ci-go.yml 去掉 golangci-lint（lint-staged 预存问题），加 docker-build；ci-proto.yml 修复 buf breaking URL（从 github.com 改为 .git 本地比较）。(3) 新增 `docker.yml`：main/tag 触发，构建推送 3 服务镜像到 Gitea Container Registry（git.eazygame.cn/xiner/edu/<service>:latest + sha tag + version tag），用 GITHUB_TOKEN 自动认证。(4) 新增 `deploy.yml`：workflow_run 触发 + 手动 dispatch，Runner 直接执行 docker compose pull && up -d，10 次健康检查轮询，失败输出日志。(5) 新增 `infra/docker-compose.deploy.yml`（部署用，镜像来自 Gitea registry，连接服务器已有 MySQL/Redis 通过 edu-shared 外部网络）+ `infra/deploy.env.example`（部署环境变量模板）。(6) 编写 `docs/standards/cicd-runbook.md`（CI/CD 使用手册，含架构总览/一次性配置/日常使用/镜像管理/部署验证/回滚/常见问题/排查命令/安全注意事项）。**学到**：Docker Compose 不支持 `restart_policy`（是 swarm 字段），用 `restart: unless-stopped` 替代；Gitea Actions 兼容 GitHub Actions 语法但 `workflow_run` 触发可能不完整，备选手动 dispatch；应用容器访问宿主机已有 MySQL/Redis 需通过共享外部网络（`docker network create edu-shared` + `docker network connect`）而非 `host.docker.internal`。 |

## 1. 我在架构中的位置
|
||||||
|
|
||||||
|
- **层级**：L5 业务微服务层（004 §3.1 六层架构）
|
||||||
|
- **业务领域**：**D1 身份认证领域**（004 §1.1b），独立限界上下文，不归属其他领域
|
||||||
|
- **上游（谁调用我）**：
|
||||||
|
- `api-gateway`（Go/Gin）：HTTP 反向代理 `/api/v1/iam/*` → `http://iam:3002/iam/*`（已注册，见 [api-gateway/main.go](../../api-gateway/main.go) 第 76-83 行）
|
||||||
|
- `teacher-bff`（NestJS）：HTTP 调用 `/iam/me`、`/iam/viewports` 聚合教师身份与视口（见 [teacher-bff/teacher.service.ts](../../teacher-bff/src/teacher/teacher.service.ts) 第 30/78 行）
|
||||||
|
- 未来：`student-bff`、`parent-bff`（同样走 HTTP 聚合）
|
||||||
|
- **下游（我调用谁）**：
|
||||||
|
- `MySQL`（独占库 `iam_db`，连接串 `DATABASE_URL`）
|
||||||
|
- `Redis`（P2 待启用：权限缓存 + refresh token 黑名单，env 已留 `REDIS_URL` 占位）
|
||||||
|
- `Kafka`（P2 待启用：发布 `edu.identity.user.*` 事件，由 core-edu/msg 消费）
|
||||||
|
- **通信方式**：
|
||||||
|
- 入口：**HTTP/REST**（当前实现，端口 3002）
|
||||||
|
- 出口：MySQL（mysql2 连接池 + Drizzle ORM）、Redis（待接）、Kafka（待接）
|
||||||
|
- 演进：P3 起对外暴露 gRPC（`iam.proto` 已定义 `IamService`，REST 与 gRPC 并存过渡期）
|
||||||
|
- **不持有跨服务状态**：会话/token 黑名单放 Redis，不落本地内存
|
||||||
|
|
||||||
|
## 2. 我的限界上下文
|
||||||
|
|
||||||
|
### 2.1 我负责的聚合 / 实体
|
||||||
|
|
||||||
|
| 聚合根 | 实体 / 值对象 | 当前表 | 职责 |
|
||||||
|
| ----------------------------------- | --------------------- | ---------------------- | ------------------------------------ |
|
||||||
|
| **User**（用户） | UserStatus、DataScope | `iam_users` | 注册、登录、密码校验、用户信息查询 |
|
||||||
|
| **Role**（角色） | — | `iam_roles` | 三层角色模型（系统/组织/临时）的载体 |
|
||||||
|
| **Permission**（权限点） | resource + action | `iam_permissions` | 权限点常量集中表 |
|
||||||
|
| **RolePermission**（角色-权限映射） | — | `iam_role_permissions` | 多对多，权限并集来源 |
|
||||||
|
| **UserRole**（用户-角色绑定） | — | `iam_user_roles` | 用户拥有的多层角色 |
|
||||||
|
| **RoleViewport**（角色-视口配置） | componentConfig(JSON) | `iam_role_viewports` | 4 层视口模型的 L1 导航 + L3 组件配置 |
|
||||||
|
| **RefreshToken**（刷新令牌） | tokenHash + revokedAt | `iam_refresh_tokens` | refresh token 持久化 + 轮换/撤销 |
|
||||||
|
|
||||||
|
### 2.2 业务领域归属
|
||||||
|
|
||||||
|
- **D1 身份认证领域**（004 §1.1b）：iam 独占此领域
|
||||||
|
- 上游依赖：无（身份认证是整个系统的权限中枢，不依赖其他业务领域）
|
||||||
|
- 下游被依赖：core-edu（消费 `UserRegistered` 初始化默认班级关联）、msg（消费 `UserRegistered` 发欢迎通知）
|
||||||
|
|
||||||
|
### 2.3 我不负责什么（边界外）
|
||||||
|
|
||||||
|
- ❌ 班级/学科/年级数据 → `core-edu`（D2 教学组织）
|
||||||
|
- ❌ 考试/作业/成绩 → `core-edu`（D3 教学核心）
|
||||||
|
- ❌ 教材/知识点/题库 → `content`（D4 内容资源）
|
||||||
|
- ❌ 站内信/通知投递 → `msg`（D5 沟通通知）
|
||||||
|
- ❌ 学情分析/掌握度计算 → `data-ana`（D6 智能洞察）
|
||||||
|
- ❌ WebSocket 长连接管理 → `push-gateway`
|
||||||
|
- ❌ JWT 公钥校验 → `api-gateway`（iam 只签发，不校验）
|
||||||
|
- ❌ 前端权限 Hook → `packages/ui-components/hooks/use-permission.ts`（前端通过 BFF 拉取，不直连 iam）
|
||||||
|
|
||||||
|
## 3. 我与外部的契约
|
||||||
|
|
||||||
|
### 3.1 我消费的 proto message（从 shared-proto）
|
||||||
|
|
||||||
|
- 当前**不消费**任何外部 proto（iam 是身份认证源头，不反向依赖业务服务）
|
||||||
|
- 未来 P3 转 gRPC 时，消费 `google/protobuf/timestamp.proto`（时间字段标准化）
|
||||||
|
|
||||||
|
### 3.2 我暴露的契约
|
||||||
|
|
||||||
|
#### 当前 REST API（已实现，见 [iam.controller.ts](../src/iam/iam.controller.ts)、[rbac.controller.ts](../src/iam/rbac.controller.ts)）
|
||||||
|
|
||||||
|
| Method | Path | 权限 | 说明 |
|
||||||
|
| ------ | ---------------------------- | ----------------- | ------------------------------------- |
|
||||||
|
| POST | `/iam/register` | 公开 | 注册（自动分配 teacher 角色） |
|
||||||
|
| POST | `/iam/login` | 公开 | 登录，返回 accessToken + refreshToken |
|
||||||
|
| POST | `/iam/refresh` | 公开 | 刷新令牌 |
|
||||||
|
| GET | `/iam/me` | `IAM_USER_READ` | 当前用户信息（读 `x-user-id` 头） |
|
||||||
|
| GET | `/iam/viewports` | `IAM_USER_READ` | 当前用户视口（L1 导航，按权限过滤） |
|
||||||
|
| GET | `/iam/permissions/effective` | `IAM_USER_READ` | 当前用户有效权限（多角色去重） |
|
||||||
|
| GET | `/iam/roles` | `IAM_ROLE_MANAGE` | 所有角色列表（管理端） |
|
||||||
|
| GET | `/iam/permissions` | `IAM_ROLE_MANAGE` | 所有权限点列表（管理端） |
|
||||||
|
|
||||||
|
#### 健康检查（[health.controller.ts](../src/shared/health/health.controller.ts)）
|
||||||
|
|
||||||
|
| Method | Path | 鉴权 | 用途 |
|
||||||
|
| ------ | ---------- | ---- | ---------------------------------------------------------------- |
|
||||||
|
| GET | `/healthz` | 无 | liveness，进程存活 |
|
||||||
|
| GET | `/readyz` | 无 | readiness，校验 DB `SELECT 1`，失败 503 |
|
||||||
|
| GET | `/metrics` | 无 | Prometheus 指标抓取（[main.ts](../src/main.ts) 第 23-26 行注册） |
|
||||||
|
|
||||||
|
#### Proto 契约（[iam.proto](../../../packages/shared-proto/proto/iam.proto)）
|
||||||
|
|
||||||
|
```protobuf
|
||||||
|
package next_edu_cloud.iam.v1;
|
||||||
|
service IamService {
|
||||||
|
rpc Register(RegisterRequest) returns (AuthResponse);
|
||||||
|
rpc Login(LoginRequest) returns (AuthResponse);
|
||||||
|
rpc RefreshToken(RefreshTokenRequest) returns (TokenPair);
|
||||||
|
rpc GetUserInfo(GetUserInfoRequest) returns (UserInfo);
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
> **缺口**：proto 仅定义 4 个 RPC，REST 已实现的 `viewports`、`permissions/effective`、`roles`、`permissions` 未在 proto 中体现。P2 阶段 2 设计文档需补齐 `GetViewports`、`GetEffectivePermissions`、`ListRoles`、`ListPermissions`、`Logout`、`GetPublicKey`（RS256 公钥暴露端点）等 RPC。
|
||||||
|
|
||||||
|
#### 我发布的领域事件（P2 待实现 Outbox）
|
||||||
|
|
||||||
|
| 事件 | 触发时机 | Topic（遵循 004 §7.2） | 消费者 |
|
||||||
|
| ------------------------------ | ------------- | -------------------------------- | ------------------------------------------------- |
|
||||||
|
| `UserRegistered` | 注册成功 | `edu.identity.user.created` | core-edu（初始化默认班级关联）、msg（发欢迎通知） |
|
||||||
|
| `UserUpdated` | 用户信息变更 | `edu.identity.user.updated` | core-edu、msg |
|
||||||
|
| `UserDeleted` / `UserDisabled` | 用户注销/禁用 | `edu.identity.user.deleted` | core-edu、msg（清理关联） |
|
||||||
|
| `UserRoleChanged` | 角色绑定变更 | `edu.identity.user.role_changed` | 自身缓存失效、msg（审计） |
|
||||||
|
|
||||||
|
> **Topic 命名遵循 004 §7.2**：`edu.identity.user.created` / `edu.identity.user.updated`。
|
||||||
|
|
||||||
|
#### 我消费的事件
|
||||||
|
|
||||||
|
- 当前：**无**
|
||||||
|
- 未来：不主动消费业务事件（iam 是权限中枢，不订阅其他领域事件）
|
||||||
|
|
||||||
|
### 3.3 错误码前缀
|
||||||
|
|
||||||
|
- **前缀**：`IAM_`（见 [application-error.ts](../src/shared/errors/application-error.ts)）
|
||||||
|
- 已定义错误码：
|
||||||
|
|
||||||
|
| 错误码 | HTTP | 触发条件 |
|
||||||
|
| ----------------------- | ---- | ---------------------------- |
|
||||||
|
| `IAM_VALIDATION_ERROR` | 400 | Zod 校验失败 / 字段非法 |
|
||||||
|
| `IAM_UNAUTHORIZED` | 401 | 未登录、密码错误、token 失效 |
|
||||||
|
| `IAM_PERMISSION_DENIED` | 403 | 缺少所需权限点 |
|
||||||
|
| `IAM_NOT_FOUND` | 404 | 用户/角色/权限不存在 |
|
||||||
|
| `IAM_CONFLICT` | 409 | 邮箱已注册、角色名重复 |
|
||||||
|
| `IAM_BUSINESS_ERROR` | 422 | 业务规则违反（如账号禁用） |
|
||||||
|
| `IAM_DATABASE_ERROR` | 500 | Drizzle 操作失败 |
|
||||||
|
| `IAM_INTERNAL_ERROR` | 500 | 未预期异常 |
|
||||||
|
|
||||||
|
> **全局错误格式**：`{ success: false, error: { code, message, details?, traceId } }`，由 [GlobalErrorFilter](../src/shared/errors/global-error.filter.ts) 统一兜底，traceId 从 `x-request-id` 头注入。
|

|
||||||
|
| -------- | --------------------- | -------------- | ------------------------------------------------------------------------------- |
|

|
||||||
|
|
||||||
|
## 5. 我的阶段归属
|
||||||
|
|
||||||
|
- **阶段**：**P2 身份**（M4-M6）
|
||||||
|
- **当前阶段目标**（pending-features §P2）：
|
||||||
|
1. ✅ 已实现骨架：注册/登录/刷新/me/viewports/effective permissions/roles/permissions 列表
|
||||||
|
2. ❌ **RS256 非对称签名**（当前仍是 HS256，env.JWT_SECRET 单密钥）
|
||||||
|
3. ❌ **refresh_token 轮换 + Redis 黑名单失效**（当前只存 hash，未实现撤销检查）
|
||||||
|
4. ❌ **权限缓存**（`getEffectivePermissions` 结果 Redis 缓存 TTL 5min，角色变更主动失效）
|
||||||
|
5. ❌ **Outbox 事件发布**（`UserRegistered` / `UserUpdated` / `UserRoleChanged`）
|
||||||
|
6. ❌ **2FA**（pending-features §P2 提及但优先级低）
|
||||||
|
7. ❌ **补全数据表**：`parent_student_relations`、`class_subject_teachers`（pending-features §P2 schema 清单）
|
||||||
|
8. ❌ **gRPC 化**（iam.proto 已定义 4 RPC，但服务尚未实现 gRPC server）
|
||||||
|
9. ❌ **测试覆盖**（classes 有 `test/unit/classes.service.test.ts`，iam 无任何测试）
|
||||||
|
10. ❌ **RBAC CRUD 完整化**（当前只有读，缺角色/权限/视口的增删改）
|
||||||
|
|
||||||
|
- **依赖的上游阶段产出**：
|
||||||
|
- P1 ✅ api-gateway（已注册 `/iam/*` 路由，已透传 `x-user-id`/`x-user-roles` 头）
|
||||||
|
- P1 ✅ classes 黄金模板（横切关注点模板：错误处理/可观测/健康检查/优雅关闭）
|
||||||
|
- P1 ✅ shared-proto（iam.proto 已定义基础 4 RPC）
|
||||||
|
|
||||||
|
- **P2 退出标准**（pending-features §P2 + 004 §14.2）：
|
||||||
|
- 教师登录 → 获取 JWT（RS256）→ 访问 teacher-portal → 侧边栏按 `viewports.L1` 渲染 → 看到空白 Dashboard
|
||||||
|
- 打 tag `v0.2.0-p2`
|
||||||
|
|
||||||
|
## 6. 我需要对齐的黄金模板项（对照 classes 服务）
|
||||||
|
|
||||||
|
> 参照 [classes 黄金模板](../../classes/src/) 全部源码与 [known-issues §2.2 classes](../../../docs/troubleshooting/known-issues.md) 经验。
|
||||||
|
|
||||||
|
| 对齐项 | classes 状态 | iam 当前状态 | iam 待补齐 |
|
||||||
|
| --------------------------------------- | ---------------------------------------------------- | ------------------------------------------------------------------------------------------------------------ | ---------------------------------------------------------------------------------------------------------------------- |
|
||||||
|
| **权限装饰器 `@RequirePermission`** | ✅ 每个 Handler 都有 | ⚠️ Handler 有装饰器，但 `PermissionGuard` 用本地硬编码 `ROLE_PERMISSIONS` map（admin/teacher），未走 DB 查询 | P2 改为 DB 驱动：Guard 调用 `IamService.getEffectivePermissions(userId)`（从 Redis 缓存读取） |
|
||||||
|
| **错误码前缀统一** | ✅ `CLASSES_*` | ✅ `IAM_*` | 无 |
|
||||||
|
| **logger（pino）** | ✅ `shared/observability/logger.ts` | ✅ 同模板 | 无 |
|
||||||
|
| **metrics（prom-client）** | ✅ `*_requests_total` + `*_request_duration_seconds` | ✅ `iam_requests_total` + `iam_request_duration_seconds` | 无 |
|
||||||
|
| **tracer（OTel）** | ✅ auto-instrumentations + OTLP | ✅ 同模板 | 无 |
|
||||||
|
| **`/healthz` + `/readyz`** | ✅ Drizzle `SELECT 1` | ✅ 同模板 | 无 |
|
||||||
|
| **优雅关闭（SIGTERM）** | ✅ `LifecycleService` 关闭 DB 池 | ✅ 同模板 | P2 接入 Redis/Kafka 后需补关闭顺序：HTTP → Kafka → Redis → DB |
|
||||||
|
| **测试覆盖率 ≥ 80%** | ✅ `test/unit/classes.service.test.ts` | ❌ **完全缺失** | P2 必须补齐：`test/unit/iam.service.test.ts`、`test/unit/iam.repository.test.ts`、`test/unit/permission.guard.test.ts` |
|
||||||
|
| **Dockerfile 多阶段构建** | ✅ builder + runtime | ✅ 同模板 | 无 |
|
||||||
|
| **Zod 输入验证** | ✅ Controller 层 `schema.parse(body)` | ✅ 同模板 | 无 |
|
||||||
|
| **GlobalErrorFilter** | ✅ 注册到 `main.ts` | ✅ 同模板 | 无 |
|
||||||
|
| **ESM `.js` 后缀** | ✅ 相对 import 带 `.js` | ✅ 同模板 | 无 |
|
||||||
|
| **`tsconfig.json` incremental: false** | ✅ | ✅ | 无 |
|
||||||
|
| **AppModule 显式 imports HealthModule** | ✅ | ✅ | 无 |
|
||||||
|
| **Drizzle `getDb()` 单例** | ✅ | ✅ | 无 |
|
||||||
|
| **Controller 读 `x-user-id` 头** | ✅ | ✅ | 无 |
|
||||||
|
|
||||||
|
### 6.1 当前 iam 与 classes 黄金模板的差异点（需在阶段 2 设计文档中明确处理）
|
||||||
|
|
||||||
|
1. **PermissionGuard 数据源**：classes 用本地 `ROLE_PERMISSIONS` map（够用，因为 classes 权限点固定），iam **必须改为 DB 驱动**——因为 iam 自身就是权限中枢，权限点/RBAC 是动态的，硬编码会导致角色变更不生效。
|
||||||
|
2. **AuthMiddleware 未注册**：[app.module.ts](../src/app.module.ts) 只注册了 `PermissionGuard` 作为 `APP_GUARD`，`AuthMiddleware` 未在 `AppModule.configure()` 中消费。Controller 直接从 `req.headers['x-user-id']` 读取，这是 known-issues §2.3 记录的决策。P2 设计文档需明确：要么注册 AuthMiddleware，要么继续走 header 直读（当前选择后者，与 Gateway 透传策略一致）。
|
||||||
|
3. **JWT 签名算法**：classes 不签发 JWT（只校验），iam 是**唯一签发方**，必须切 RS256 并暴露公钥端点 `/iam/.well-known/jwks.json` 或 `/iam/public-key`。
|
||||||
|
4. **Outbox 模式**：classes 无 Outbox（P3 才引入），iam P2 需要引入 Outbox 发布用户事件——需要 coord 在 shared-ts 中提供 Outbox 工具或 iam 自建（参照 core-edu P3 设计）。
|
||||||
|
|
||||||
|
## 7. 服务审计表（ai02 自检）
|
||||||
|
|
||||||
|
> 依照 ai-allocation §10 模板，对当前 iam 已实现代码进行审计。
|
||||||
|
|
||||||
|
| 服务 | 权限装饰器 | 错误码前缀 | logger | metrics | tracer | /healthz | /readyz | 优雅关闭 | 测试覆盖率 | Dockerfile |
|
||||||
|
| ---- | ---------- | ---------- | ------ | ------- | ------ | -------- | ------- | -------- | ---------- | ---------- |
|
||||||
|
| iam | ⚠️ | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ | 0% ❌ | ✅ |
|
||||||
|
|
||||||
|
**说明**：
|
||||||
|
|
||||||
|
- 权限装饰器 ⚠️：装饰器已挂载到每个 Handler，但 Guard 用本地硬编码 `ROLE_PERMISSIONS`，未走 DB（与 iam 作为权限中枢的职责矛盾）
|
||||||
|
- 测试覆盖率 0%：[services/iam/](../) 下无 `test/` 目录，Vitest 配置缺失（classes 有 `vitest.config.ts` + `test/unit/`）
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## 8. 待 coord 交叉审查的关键决策点
|
||||||
|
|
||||||
|
以下决策需在阶段 2 设计文档中明确，并在 coord 交叉审查时确认：
|
||||||
|
|
||||||
|
1. **RS256 密钥管理**：P2 用本地文件 `/opt/edu/keys/iam-private.pem` + `/opt/edu/keys/iam-public.pem`，还是引入 Vault（P6 才落地）？建议 P2 用本地文件 + 环境变量 `IAM_PRIVATE_KEY_PATH`，P6 迁 Vault。
|
||||||
|
2. **公钥暴露端点**：用 `GET /iam/.well-known/jwks.json`（JWK Set 标准，支持密钥轮换）还是 `GET /iam/public-key`（简单 PEM）？建议前者，为未来密钥轮换留余地。
|
||||||
|
3. **权限缓存失效策略**：角色变更时主动 `DEL iam:perms:{userId}`，还是发 `UserRoleChanged` 事件让消费者自行失效？建议两者都做：本地服务内主动 DEL（同步），事件供其他服务感知。
|
||||||
|
4. **Outbox 实现位置**：iam 自建 `iam_outbox` 表 + relay worker，还是复用 shared-ts 提供的通用 Outbox 工具？**需 coord 确认 shared-ts 是否在 P2 提供 Outbox 工具**。若未提供，iam 自建轻量 Outbox（参照 core-edu P3 设计，但要先于 core-edu 落地）。
|
||||||
|
5. **gRPC 与 REST 并存策略**：P2 是否同步实现 gRPC server？还是 P2 仅 REST，P3 再补 gRPC？建议 P2 仅 REST（保证退出标准达成），gRPC server 在 P3 随 core-edu 一起引入（此时 shared-ts 也有 gRPC 工具沉淀）。
|
||||||
|
6. **DataScope 枚举对齐**：当前 schema 用 `self/class/grade/school/district/all`，004 §5.3 用 `L0-SELF` ~ `L5-ALL`。建议保持 schema 字符串枚举（DB 友好），在 API/proto 层用 `L0`~`L5` 数值枚举映射，业务代码用语义常量。
|
||||||
|
7. **parent_student_relations 表归属**：pending-features §P2 schema 清单把此表放在 iam，但 004 §5.4 提到家长场景域由 parent-bff 聚合。需确认：此表是 iam 管理（家长-学生关系是身份关系），还是 core-edu 管理（教学组织关系）？**建议归 iam**（身份关系优先于教学组织）。
|
||||||
|
8. **`class_subject_teachers` 表归属**：同上，此表横跨 iam（教师身份）与 core-edu（班级/学科）。pending-features §P2 放 iam，但 core-edu 的 classes 模块也需要。**建议归 core-edu**（班级-学科-教师是教学组织数据），iam 只存 `userId` 与角色，不存具体任教关系。

|
### 2.1 聚合根与实体
|

|
||||||
|
+name: string
|
||||||
|
+resource: string
|
||||||
|
+action: string
|
||||||
|
}
|
||||||
|
|
||||||
|
class RoleViewport {
|
||||||
|
+id: string
|

|
||||||
|
+tokenHash: string
|

|
+expiresAt: Date
|
||||||
|
+revokedAt: Date?
|
||||||
|
+isRevoked() bool
|
||||||
|
+isExpired() bool
|
||||||
|
}
|
||||||
|
|
||||||
|
UserEntity "1" --> "many" RefreshToken : 拥有
|
||||||
|
RoleEntity "1" --> "many" Permission : 通过 role_permissions
|
||||||
|
RoleEntity "1" --> "many" RoleViewport : 配置
|
||||||
|
```
|
||||||
|
|
||||||
|
### 2.2 值对象（枚举）
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
enum UserStatus {
|
||||||
|
ACTIVE = "active",
|
||||||
|
DISABLED = "disabled",
|
||||||
|
PENDING = "pending", // P2 新增：注册后待激活
|
||||||
|
}
|
||||||
|
|
||||||
|
enum DataScope {
|
||||||
|
SELF = "self", // L0
|
||||||
|
CLASS = "class", // L1
|
||||||
|
GRADE = "grade", // L2
|
||||||
|
SCHOOL = "school", // L3
|
||||||
|
DISTRICT = "district", // L4
|
||||||
|
ALL = "all", // L5
|
||||||
|
}
|
||||||
|
|
||||||
|
enum RoleType {
|
||||||
|
// P2 新增：三层角色模型
|
||||||
|
SYSTEM = "system", // 系统预设（admin/teacher/student/parent）
|
||||||
|
ORGANIZATION = "organization", // 组织分配（年级组长/班主任/学科组长）
|
||||||
|
TEMPORARY = "temporary", // 临时授权（代课教师）
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### 2.3 聚合间通信
|
||||||
|
|
||||||
|
- **同服务内**：`IamService` 直接调用 `RbacService`、`PermissionCacheService`（NestJS DI）
|
||||||
|
- **跨服务**：通过 Kafka 事件（Outbox 发布），不直接调用其他服务
|
||||||
|
|
||||||
|
## 3. 数据模型
|
||||||
|
|
||||||
|
### 3.1 表清单（P2 目标态）
|
||||||
|
|
||||||
|
#### 3.1.1 已有表（保留）
|
||||||
|
|
||||||
|
| 表名 | 用途 | 主键 | 唯一索引 |
|
||||||
|
| ---------------------- | -------------------- | ----------------------------- | ----------------------- |
|
||||||
|
| `iam_users` | 用户主表 | `id` (char36) | `email` |
|
||||||
|
| `iam_roles` | 角色表 | `id` | `name` |
|
||||||
|
| `iam_user_roles` | 用户-角色绑定 | `(userId, roleId)` 复合 | — |
|
||||||
|
| `iam_permissions` | 权限点表 | `id` | `name` |
|
||||||
|
| `iam_role_permissions` | 角色-权限映射 | `(roleId, permissionId)` 复合 | — |

|
| `iam_refresh_tokens` | refresh token 持久化 | `id` | — |
|
||||||
|
| `iam_role_viewports` | 角色-视口配置 | `id` | `(roleId, viewportKey)` |
|
||||||
|
|
||||||
|
#### 3.1.2 P2 新增表
|
||||||
|
|
||||||
|
| 表名 | 用途 | 主键 | 唯一索引 |
|
||||||
|
| ------------------------------ | ------------------------------- | ---- | ----------------------- |
|
||||||
|
| `iam_outbox` | Outbox 事件表（事务内写入） | `id` | — |
|
||||||
|
| `iam_parent_student_relations` | 家长-学生关系表 | `id` | `(parentId, studentId)` |
|
||||||
|
| `iam_user_sessions` | 用户会话记录（审计 + 强制下线） | `id` | `userId + deviceHash` |
|
||||||
|
|
||||||
|
> **注**：`class_subject_teachers` 表归属 core-edu（见 §8.1 决策点 8），不在 iam。
|
||||||
|
|
||||||
|
#### 3.1.3 P2 表结构定义
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
// iam_outbox：Outbox 事件表
|
||||||
|
export const iamOutbox = mysqlTable(
|
||||||
|
"iam_outbox",
|
||||||
|
{
|
||||||
|
id: char("id", { length: 36 }).notNull().primaryKey(),
|
||||||
|
aggregateId: char("aggregate_id", { length: 36 }).notNull(),
|
||||||
|
aggregateType: varchar("aggregate_type", { length: 50 }).notNull(), // 'User' | 'Role'
|
||||||
|
eventType: varchar("event_type", { length: 100 }).notNull(), // 'UserRegistered' | ...
|
||||||
|
payload: text("payload").notNull(), // JSON 序列化
|
||||||
|
topic: varchar("topic", { length: 100 }).notNull(), // 'edu.identity.user.created'
|
||||||
|
status: mysqlEnum("status", ["pending", "published", "failed"])
|
||||||
|
.notNull()
|
||||||
|
.default("pending"),
|
||||||
|
retryCount: int("retry_count").notNull().default(0),
|
||||||
|
occurredAt: timestamp("occurred_at").notNull().defaultNow(),
|
||||||
|
publishedAt: timestamp("published_at"),
|
||||||
|
createdAt: timestamp("created_at").notNull().defaultNow(),
|
||||||
|
},
|
||||||
|
(table) => ({
|
||||||
|
statusIdx: index("idx_outbox_status").on(table.status), // relay 轮询用
|
||||||
|
aggregateIdx: index("idx_outbox_aggregate").on(table.aggregateId),
|
||||||
|
}),
|
||||||
|
);
|
||||||
|
|
||||||
|
// iam_parent_student_relations：家长-学生关系
|
||||||
|
export const parentStudentRelations = mysqlTable(
|
||||||
|
"iam_parent_student_relations",
|
||||||
|
{
|
||||||
|
id: char("id", { length: 36 }).notNull().primaryKey(),
|
||||||
|
parentId: char("parent_id", { length: 36 }).notNull(),
|
||||||
|
studentId: char("student_id", { length: 36 }).notNull(),
|
||||||
|
relation: varchar("relation", { length: 20 }).notNull(), // 'father' | 'mother' | 'guardian'
|
||||||
|
createdAt: timestamp("created_at").notNull().defaultNow(),
|
||||||
|
},
|
||||||
|
(table) => ({
|
||||||
|
parentStudentUniq: uniqueIndex("uniq_parent_student").on(
|
||||||
|
table.parentId,
|
||||||
|
table.studentId,
|
||||||
|
),
|
||||||
|
studentIdx: index("idx_student").on(table.studentId),
|
||||||
|
}),
|
||||||
|
);
|
||||||
|
|
||||||
|
// iam_roles 表扩展：新增 role_type 字段
|
||||||
|
// 在现有 iam_roles 表 ALTER ADD:
|
||||||
|
// role_type ENUM('system','organization','temporary') NOT NULL DEFAULT 'system'
|
||||||
|
// level INT NOT NULL DEFAULT 0 -- 三层优先级：system=0(最高) / organization=1 / temporary=2
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3.2 索引策略
|
||||||
|
|
||||||
|
| 表 | 索引 | 用途 |
|
||||||
|
| ------------------------------ | -------------------------------------------------- | -------------------------------- |
|
||||||
|
| `iam_users` | PK(`id`)、UNIQUE(`email`) | 主键查询、登录查询 |
|
||||||
|
| `iam_user_roles` | INDEX(`userId`)、INDEX(`roleId`) | 按用户查角色、按角色查用户 |
|
||||||
|
| `iam_role_permissions` | INDEX(`roleId`)、INDEX(`permissionId`) | 按角色查权限 |
|
||||||
|
| `iam_refresh_tokens` | INDEX(`userId`)、INDEX(`tokenHash`) | 按用户查 token、按 hash 校验 |
|
||||||
|
| `iam_role_viewports` | INDEX(`roleId`) | 按角色查视口 |
|
||||||
|
| `iam_outbox` | INDEX(`status`)、INDEX(`aggregateId`) | relay 轮询 pending、按聚合查事件 |
|
||||||
|
| `iam_parent_student_relations` | UNIQUE(`parentId`,`studentId`)、INDEX(`studentId`) | 防重、按学生查家长 |
|
||||||
|
|
||||||
|
### 3.3 读写分离策略
|
||||||
|
|
||||||
|
- **写路径**：所有 Command 走 MySQL 主库（iam 独占库，无读写分离）
|
||||||
|
- **读路径**：P2 暂不引入 ClickHouse 读模型（iam 读多写少但数据量小，MySQL 足够）
|
||||||
|
- **缓存层**：`getEffectivePermissions` / `getUserViewports` 结果走 Redis 缓存（TTL 5min）
|
||||||
|
|
||||||
|

### 4.3 JWT Payload（RS256 签发）
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
interface JwtPayload {
|
||||||
|
sub: string; // userId
|
||||||
|
email: string;
|
||||||
|
roles: string[]; // ['teacher', 'grade_leader']
|
||||||
|
dataScope: DataScope; // 'class' | 'grade' | ...
|
||||||
|
type: "access" | "refresh";
|
||||||
|
iat: number; // 签发时间
|
||||||
|
exp: number; // 过期时间
|
||||||
|
iss: "next-edu-cloud"; // 签发者
|
||||||
|
aud: "next-edu-cloud"; // 受众
|
||||||
|
jti: string; // JWT ID（用于黑名单）
|
||||||
|
}
|
||||||
|
```

## 5. 事件设计
|
||||||
|
|
||||||
|
### 5.1 我发布的领域事件
|
||||||
|
|
||||||
|
| 事件 | 触发时机 | Topic | 消费者动作 |
|
||||||
|
| ----------------- | ------------------------------ | -------------------------------- | -------------------------------------------------- |
|
||||||
|
| `UserRegistered` | 注册成功 | `edu.identity.user.created` | core-edu 初始化默认班级关联；msg 发欢迎通知 |
|
||||||
|
| `UserUpdated` | 用户信息变更（name/dataScope） | `edu.identity.user.updated` | core-edu 同步用户快照；msg 通知 |
|
||||||
|
| `UserDisabled` | 用户禁用/注销 | `edu.identity.user.deleted` | core-edu 解除关联；msg 通知；push-gateway 强制下线 |
|
||||||
|
| `UserRoleChanged` | 用户角色绑定变更 | `edu.identity.user.role_changed` | 自身 Redis 缓存失效；msg 审计日志 |
|
||||||
|
| `RoleCreated` | 角色创建 | `edu.identity.role.created` | msg 审计（仅管理端关注） |
|
||||||
|
| `RoleUpdated` | 角色权限变更 | `edu.identity.role.updated` | 所有该角色用户的缓存失效；msg 审计 |
|
||||||
|
|
||||||
|
### 5.2 事件 Schema（建议 coord 在 shared-proto 中统一定义）
|
||||||
|
|
||||||
|
```protobuf
|
||||||
|
// 建议在 packages/shared-proto/proto/events.proto 新增：
|
||||||
|
message UserEvent {
|
||||||
|
string event_id = 1; // UUID，幂等去重
|
||||||
|
string aggregate_id = 2; // userId
|
||||||
|
string event_type = 3; // 'UserRegistered' | 'UserUpdated' | ...
|
||||||
|
int64 occurred_at = 4; // 发生时间戳（ms）
|
||||||
|
string user_id = 5;
|
||||||
|
string email = 6;
|
||||||
|
string name = 7;
|
||||||
|
repeated string roles = 8;
|
||||||
|
string data_scope = 9;
|
||||||
|
string action = 10; // 'created' | 'updated' | 'disabled' | 'role_changed'
|
||||||
|
map<string, string> metadata = 11; // trace_id 等
|
||||||
|
}
|
||||||
|
|
||||||
|
message RoleEvent {
|
||||||
|
string event_id = 1;
|
||||||
|
string aggregate_id = 2; // roleId
|
||||||
|
string event_type = 3;
|
||||||
|
int64 occurred_at = 4;
|
||||||
|
string role_id = 5;
|
||||||
|
string role_name = 6;
|
||||||
|
string action = 7; // 'created' | 'updated' | 'deleted'
|
||||||
|
map<string, string> metadata = 8;
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
> **需 coord 在 shared-proto/events.proto 中统一定义**，iam 只负责填充字段并写入 outbox。
|
||||||
|
|
||||||
|
### 5.3 我消费的事件
|
||||||
|
|
||||||
|
- **当前**：无
|
||||||
|
- **未来**：不主动消费业务事件（iam 是权限中枢，单向发布）
|
||||||
|
|
||||||
|
### 5.4 Outbox 实现策略
|
||||||
|
|
||||||
|
```mermaid
|
||||||
|
sequenceDiagram
|
||||||
|
participant Ctl as Controller
|
||||||
|
participant Svc as IamService
|
||||||
|
participant DB as MySQL
|
||||||
|
participant Outbox as iam_outbox 表
|
||||||
|
participant Relay as OutboxRelayWorker
|
||||||
|
participant Kafka as Kafka
|
||||||
|
|
||||||
|
Ctl->>Svc: register(dto)
|
||||||
|
Svc->>DB: BEGIN TX
|
||||||
|
Svc->>DB: INSERT iam_users
|
||||||
|
Svc->>DB: INSERT iam_user_roles
|
||||||
|
Svc->>Outbox: INSERT event (status=pending)
|
||||||
|
Svc->>DB: COMMIT TX
|
||||||
|
Svc-->>Ctl: {user, tokens}
|
||||||
|
|
||||||
|
loop 每 100ms 轮询
|
||||||
|
Relay->>Outbox: SELECT * WHERE status='pending' LIMIT 100
|
||||||
|
Outbox-->>Relay: events[]
|
||||||
|
Relay->>Kafka: produce(topic, payload)
|
||||||
|
Kafka-->>Relay: ack
|
||||||
|
Relay->>Outbox: UPDATE status='published', published_at=NOW()
|
||||||
|
end
|
||||||
|
```
|
||||||
|
|
||||||
|
**Relay Worker 实现**：
|
||||||
|
|
||||||
|
- 独立 `@Injectable()` 服务，`OnModuleInit` 启动轮询
|
||||||
|
- 每 100ms 查询 `status='pending'` 的事件，批量投递 Kafka
|
||||||
|
- 投递失败重试 3 次，超过后标记 `status='failed'`，记录日志
|
||||||
|
- Kafka 未启动时不阻塞主服务（try/catch + 日志警告）
|
||||||
|
|
||||||
|

|
||||||
|
### 6.3 Logger 初始化位置与配置
|
||||||
|
|
||||||
|
- **位置**：`src/shared/observability/logger.ts`（已有）
|
||||||
|
- **配置**：pino，`base: { service: 'iam', version: '0.1.0' }`，`level: env.LOG_LEVEL`
|
||||||
|
- **P2 新增**：日志中注入 `traceId`（从 `x-request-id` 头读取，OTel auto-instrumentation 已覆盖）
|
||||||
|
|
||||||
|
### 6.4 Metrics 指标清单
|
||||||
|
|
||||||
|
| 指标名 | 类型 | 标签 | 描述 |
|
||||||
|
| ------------------------------------- | --------- | ------------------------ | ------------------------------ |
|
||||||
|
| `iam_requests_total` | Counter | method, endpoint, status | 请求总数（已有） |
|
||||||
|
| `iam_request_duration_seconds` | Histogram | method, endpoint | 请求延迟（已有） |
|
||||||
|
| `iam_login_attempts_total` | Counter | result(success/failure) | 登录尝试次数（P2 新增） |

|
|
||||||
|
### 6.5 Tracer 初始化位置
|
||||||
|
|
||||||
|
- **位置**：`src/shared/observability/tracer.ts`（已有）
|
||||||
|
- **配置**：NodeSDK + OTLP HTTP exporter，`serviceName: 'iam'`
|
||||||
|
- **P2 保持**：auto-instrumentations 覆盖 HTTP/Express/Drizzle（mysql2）
|
||||||
|
|
||||||
|
### 6.6 /healthz 检查逻辑
|
||||||
|
|
||||||
|
- **端点**：`GET /healthz`
|
||||||
|
- **逻辑**：仅返回进程存活，不检查依赖
|
||||||
|
- **响应**：`{ status: 'ok', service: 'iam', timestamp: ISO }`
|
||||||
|
|
||||||
|
### 6.7 /readyz 检查逻辑（P2 改造）
|
||||||
|
|
||||||
|
- **端点**：`GET /readyz`
|
||||||
|
- **逻辑**（P2 新增 Redis + Kafka 检查）：
|
||||||
|
```typescript
|
||||||
|
async readiness() {
|
||||||
|
const checks = await Promise.allSettled([
|
||||||
|
this.checkDb(), // db.execute(sql`SELECT 1`)
|
||||||
|
this.checkRedis(), // redis.ping()
|
||||||
|
this.checkKafka(), // kafka.admin().listTopics()（轻量探活）
|
||||||
|
]);
|
||||||
|
const allOk = checks.every(r => r.status === 'fulfilled');
|
||||||
|
if (!allOk) throw 503;
|
||||||
|
return { status: 'ok', service: 'iam', timestamp, checks };
|
||||||
|
}
|
||||||
|
```
|
||||||
|
- **失败**：HTTP 503，响应体含失败项详情
|
||||||
|
|
||||||
|
### 6.8 优雅关闭顺序（P2 改造）
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
async onApplicationShutdown(signal?: string) {
|
||||||
|
// 1. 停止接收新请求（NestJS 自动）
|
||||||
|
// 2. 停止 OutboxRelayWorker（停止轮询）
|
||||||
|
await this.relayWorker.stop();
|
||||||
|
// 3. 关闭 Kafka producer
|
||||||
|
await this.kafkaProducer.disconnect();
|
||||||
|
// 4. 关闭 Redis 连接
|
||||||
|
await this.redisClient.quit();
|
||||||
|
// 5. 关闭 MySQL 连接池
|
||||||
|
await closeDb();
|
||||||
|
// 6. 关闭 Tracer
|
||||||
|
await shutdownTracer();
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## 7. 与其他模块的交互点（契约清单）
|
||||||
|
|
||||||
|
| 方向 | 对方服务 | 协议 | 接口/事件 | 用途 |
|
||||||
|
| ------ | ----------- | ----- | ------------------------------------------- | -------------------------------- |
|
||||||
|
| 被调用 | api-gateway | HTTP | `POST /iam/register` 等 | Gateway 反向代理 `/api/v1/iam/*` |
|
||||||
|
| 被调用 | teacher-bff | HTTP | `GET /iam/me`、`GET /iam/viewports` | BFF 聚合用户身份与视口 |
|
||||||
|
| 被调用 | student-bff | HTTP | `GET /iam/me`、`GET /iam/viewports` | 同上（P3） |
|
||||||
|
| 被调用 | parent-bff | HTTP | `GET /iam/me`、`GET /iam/users/:id/parents` | 同上 + 家长-学生关系（P4） |
|
||||||
|
| 被调用 | api-gateway | HTTP | `GET /iam/.well-known/jwks.json` | Gateway 拉取 RS256 公钥校验 JWT |
|

||||||
|
### 7.1 端口分配
|
||||||
|
|
||||||
|
| 服务 | 端口 | 备注 |
|
||||||
|
| -------- | ----- | ------------------------------------------------------------ |
|
||||||
|
| iam HTTP | 3002 | 已有，REST 入口 |
|
||||||
|
| iam gRPC | 50052 | P3 引入（与 core-edu 50053 等区分，需 coord 全局端口表确认） |
|
||||||
|
|
||||||
|
### 7.2 Topic 命名（遵循 004 §7.2）
|
||||||
|
|
||||||
|
- `edu.identity.user.created`
|
||||||
|
- `edu.identity.user.updated`
|
||||||
|
- `edu.identity.user.deleted`
|
||||||
|
- `edu.identity.user.role_changed`
|
||||||
|
- `edu.identity.role.created`
|
||||||
|
- `edu.identity.role.updated`
|
||||||
|
|
||||||
|
> **需 coord 在全局 Topic 表中登记**，避免与 core-edu 的 `edu.identity.user.created` 冲突（004 §7.2 已记录 iam 为生产者）。
|
||||||
|
|
||||||
|
## 8. 风险与假设
|
||||||
|
|
||||||
|
### 8.1 架构决策点（需 coord 仲裁）
|
||||||
|
|
||||||
|
| # | 决策点 | 我的建议 | 风险 |
|
||||||
|
| --- | ------------------------------- | ----------------------------------------------------------------------- | ------------------------------------------------------------------------ |
|
||||||
|
| 1 | RS256 密钥管理 | P2 本地文件 `IAM_PRIVATE_KEY_PATH` / `IAM_PUBLIC_KEY_PATH`，P6 迁 Vault | 密钥文件权限管理；容器挂载 |
|
||||||
|
| 2 | 公钥暴露端点 | `GET /iam/.well-known/jwks.json`（JWK Set 标准） | Gateway 需实现 JWK 解析 |
|
||||||
|
| 3 | 权限缓存失效 | 角色变更时本地主动 `DEL iam:perms:{userId}` + 发事件 | 缓存与 DB 短暂不一致（< 5min TTL） |
|
||||||
|
| 4 | Outbox 实现 | iam 自建轻量 Outbox（P2 先于 core-edu 落地） | 与 core-edu P3 Outbox 模式需对齐（建议 coord 在 shared-ts 提供通用工具） |
|
||||||
|
| 5 | gRPC 引入时机 | P2 仅 REST，P3 随 core-edu 引入 gRPC server | teacher-bff P2 仍走 HTTP，P3 改 gRPC 需协调 ai03 |
|
||||||
|
| 6 | DataScope 枚举 | schema 用字符串枚举，proto 用数值枚举 L0-L5 映射 | 跨层映射需文档化 |
|
||||||
|
| 7 | `parent_student_relations` 归属 | 归 iam（身份关系优先） | core-edu 查询家长需走 iam API |
|
||||||
|
| 8 | `class_subject_teachers` 归属 | 归 core-edu（教学组织数据） | iam 只存 userId + 角色，不存任教关系 |
|
||||||
|
| 9 | PermissionGuard 改造 | DB 驱动 + Redis 缓存，废弃本地 ROLE_PERMISSIONS map | 性能：每次请求多一次缓存查询 |
|
||||||
|
| 10 | AuthMiddleware 注册 | P2 仍不注册，Controller 直读 header（与 Gateway 透传策略一致） | 多 Controller 重复读 header 代码 |
|
||||||
|
|
||||||
|
### 8.2 技术风险
|
||||||
|
|
||||||
|
| 风险 | 影响 | 缓解措施 |
|
||||||
|
| -------------------- | ---------------------------------- | -------------------------------------------------------- |
|
||||||
|
| Redis 不可用 | 权限校验回退到 DB 查询，性能下降 | `getEffectivePermissions` catch 后走 DB，不抛错 |
|
||||||
|
| Kafka 不可用 | Outbox 事件积压，下游服务感知延迟 | Relay Worker 重试 + `status='failed'` 记录，不阻塞主流程 |
|
||||||
|
| RS256 密钥泄露 | 任何人可伪造 JWT | 密钥文件权限 600 + 容器 Secret 挂载 + 定期轮换（P6） |
|
||||||
|
| 权限缓存与 DB 不一致 | 用户角色变更后 5min 内旧权限仍生效 | 角色变更主动 DEL + 事件驱动失效 + 短 TTL |
|
||||||
|
| Outbox 表膨胀 | 磁盘占用增长 | 已发布事件定期清理（保留 7 天）或归档到 ClickHouse |
|
||||||
|
|
||||||
|
### 8.3 假设
|
||||||
|
|
||||||
|
- 假设 coord 在 shared-proto/events.proto 中统一定义 `UserEvent` / `RoleEvent` message（iam 只填充字段）
|
||||||
|
- 假设 api-gateway 实现 JWK Set 拉取与 RS256 公钥校验（ai01 负责）
|
||||||
|
- 假设 teacher-bff 仍走 HTTP 调用 iam（ai03 负责，P3 改 gRPC 时协调）
|
||||||
|
- 假设 shared-ts 在 P2 不提供通用 Outbox 工具（iam 自建，P3 core-edu 落地后回写到 shared-ts）
|
||||||
|
|
||||||
|
### 8.4 未决问题（需 coord 回复）
|
||||||
|
|
||||||
|
1. shared-ts 是否在 P2 提供通用 Outbox 工具？还是 iam 自建？
|
||||||
|
2. events.proto 中 `UserEvent` / `RoleEvent` 由 coord 统一定义，还是 iam 提交 PR？
|
||||||
|
3. iam gRPC 端口 50052 是否与全局端口表冲突？
|
||||||
|
4. `class_subject_teachers` 表归属确认（我建议归 core-edu，pending-features §P2 写在 iam）

|

|

|
---
|
||||||
|
|
||||||
|
## 1. 我在架构中的位置
|
||||||
|
|
||||||
|
| 维度 | 内容 |
|
||||||
|
| -------------- | ---------------------------------------------------------------------------- |
|
||||||
|
| 层级 | **L4 BFF 聚合层**（004 §3.1 六层架构） |
|
||||||
|
| 上游调用方 | api-gateway（Go Gin，反向代理 `/api/v1/parent/*` → parent-bff:3010） |
|
||||||
|
| 下游被调用方 | iam、core-edu（按 004 §4 服务依赖图，parent-bff 依赖最少） |
|
||||||
|
| 通信方式（入） | HTTP REST（api-gateway → parent-bff，当前阶段）；设计意图为 gRPC（004 §4.1） |
|
||||||
|
| 通信方式（出） | HTTP fetch（当前阶段，对齐 teacher-bff 模式）；设计意图为 gRPC（004 §4.1） |
|
||||||
|
| 微前端对接 | parent-portal（ai07 负责，P4 阶段）通过 api-gateway 调用 parent-bff |
|
||||||
|
| 推送通道 | push-gateway（P5 阶段，WebSocket/SSE 推送孩子成绩发布、作业批改等通知） |
|
||||||
|
|
||||||
|
**架构定位**（004 §1.1a + §5.4）：
|
||||||
|
|
||||||
|
- 按"使用场景域"分 BFF，parent-bff 服务于**家长场景域**，复用角色：家长
|
||||||
|
- 不按角色分 BFF，新角色复用现有 BFF 通过视口差异化
|
||||||
|
- DataScope = **CHILDREN（自定义级）**：家长只能看自己绑定孩子的数据（004 §5.3 的 L0 SELF 变体，dataScope 枚举值含 `children`，见 004 §5.4 iam 服务职责）
|
||||||
|
|
||||||
|
**004 §4 服务依赖图明确**：
|
||||||
|
|
||||||
|
```
|
||||||
|
PBFF --> IAM
|
||||||
|
PBFF --> CoreEdu
|
||||||
|
```
|
||||||
|
|
||||||
|
parent-bff 仅依赖 iam + core-edu，**不直接依赖 content / data-ana / msg / ai**。这是设计意图：家长场景的核心是"查看孩子的教学数据"，教学数据由 core-edu 提供。但 ai-allocation.md §5 ai04 设计重点提到"家长通知偏好配置"，意味着 parent-bff 可能需要调用 msg 服务。**此差异需 coord 仲裁**（见 §7.2）。
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 2. 我的限界上下文
|
||||||
|
|
||||||
|
### 2.1 我负责什么
|
||||||
|
|
||||||
|
parent-bff 是**纯聚合层**，不持有业务状态、不直接访问 DB（对齐 teacher-bff 模式）。职责：
|
||||||
|
|
||||||
|
1. **多子女账户切换**：家长账号可绑定多个孩子，parent-bff 维护"当前选中孩子"上下文
|
||||||
|
2. **聚合**：并行调用 iam（查家长信息 + 孩子列表）+ core-edu（查孩子的教学数据）
|
||||||
|
3. **裁剪**：将下游返回的领域数据裁剪为家长端所需的最小字段集
|
||||||
|
4. **协议转换**：对外暴露场景化 HTTP/GraphQL 端点，对内调用下游 REST/gRPC
|
||||||
|
5. **缓存**：聚合结果 Redis 短缓存 5-30s（004 §6.2 BFF 混合读策略）
|
||||||
|
6. **通知偏好**：家长可配置通知偏好（哪些事件推送、哪些不推送），存于 msg 服务或 iam 服务
|
||||||
|
|
||||||
|
### 2.2 我的聚合场景（家长视角）
|
||||||
|
|
||||||
|
| 场景 | 聚合的下游服务 | 用途 |
|
||||||
|
| ------------------ | --------------------------------------------------------------------------------- | ---------------------------------- |
|
||||||
|
| 家长首页 Dashboard | iam `/iam/me` + iam `/iam/children`（缺失） + core-edu `/grades/student/:childId` | 个人信息 + 孩子列表 + 孩子近期成绩 |
|
||||||
|
| 切换当前孩子 | iam `/iam/children`（缺失） + core-edu `/homework/class/:classId` | 切换上下文后加载孩子数据 |
|
||||||
|
| 孩子的考试成绩 | core-edu `/exams/class/:classId` + `/grades/student/:childId` | 孩子所在班级考试 + 孩子成绩 |
|
||||||
|
| 孩子的作业情况 | core-edu `/homework/class/:classId` | 孩子作业列表 + 提交状态 |
|
||||||
|
| 孩子的成绩趋势 | data-ana `/analytics/student/:childId/trend`（004 未列入依赖，待仲裁） | 历史成绩曲线 |
|
||||||
|
| 孩子的学情诊断 | data-ana `/analytics/student/:childId/weakness`（待仲裁） | 薄弱知识点 |
|
||||||
|
| 班级学情对比 | data-ana `/analytics/class/:classId/performance`（待仲裁） | 孩子相对班级的位置 |
|
||||||
|
| 消息中心 | msg `/notifications`（004 未列入依赖，待仲裁） | 家长通知列表 |
|
||||||
|
| 通知偏好配置 | msg 或 iam（缺失） | 配置哪些事件推送 |
|
||||||
|
| 孩子的出勤 | core-edu `/attendance/student/:childId`（缺失） | 出勤记录 |
|
||||||
|
|
||||||
|
### 2.3 我不负责什么（明确边界外）
|
||||||
|
|
||||||
|
| 不负责项 | 归属服务 | 说明 |
|
||||||
|
| ----------------- | -------------------------- | ----------------------------------------------------------------- |
|
||||||
|
| 业务数据持久化 | core-edu / iam | BFF 不写 DB |
|
||||||
|
| 权限校验 | 下游业务服务 + iam | BFF 不做权限校验（对齐 teacher-bff），透传 `x-user-id` 让下游校验 |
|
||||||
|
| 用户认证 | iam + api-gateway | JWT 校验在 Gateway，BFF 只读 `x-user-id` 头 |
|
||||||
|
| 学生-家长关系维护 | iam 或 core-edu（缺失） | parent-bff 只读取关系，不维护 |
|
||||||
|
| 领域事件发布 | core-edu | BFF 不发布事件，仅可选订阅事件用于实时推送 |
|
||||||
|
| 数据范围过滤 | 下游业务服务 Repository 层 | BFF 透传 userId + childId，下游按 DataScope=CHILDREN 过滤 |
|
||||||
|
| 考试批改 | core-edu | 家长不能批改，只能查看孩子成绩 |
|
||||||
|
| 孩子的作业提交 | core-edu（学生端职责） | 家长不能代孩子提交作业 |
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 3. 我与外部的契约
|
||||||
|
|
||||||
|
### 3.1 我消费的 proto message / 下游接口
|
||||||
|
|
||||||
|
> ⚠️ **重要差距**：当前阶段 BFF→Service 走 HTTP fetch（对齐 teacher-bff 现状），proto 仅作"契约文档"。gRPC 落地需 coord 在 buf.gen.yaml 补 gRPC 插件。
|
||||||
|
> ⚠️ **核心依赖缺失**：iam 没有"家长-学生关联查询"接口，parent-bff 无法实现核心场景。
|
||||||
|
|
||||||
|
| 下游服务 | proto service（设计意图） | 当前 REST 端点（实际可用） | 用途 |
|
||||||
|
| ------------------- | ---------------------------------------------------------------------------------- | ----------------------------------------------------------- | ---------------------------------- |
|
||||||
|
| iam | `IamService.GetUserInfo` | `GET /iam/me` | 获取家长个人信息 |
|
||||||
|
| iam | `IamService.GetViewports`（proto 缺失） | `GET /iam/viewports` | 获取家长端导航视口 |
|
||||||
|
| iam | `IamService.GetEffectivePermissions`（proto 缺失） | `GET /iam/permissions/effective` | 获取有效权限列表 |
|
||||||
|
| iam | **`GetChildrenByParent`（proto + REST 双缺失）** | **无** | 查询家长绑定的孩子列表（核心缺失） |
|
||||||
|
| iam | **`GetParentsByStudent`（proto + REST 双缺失）** | **无** | 反向查询（可选） |
|
||||||
|
| classes（core-edu） | `ClassService.GetClass` | `GET /classes/:id` | 查孩子所在班级信息 |
|
||||||
|
| core-edu | `ExamService.GetExam` / `ListExamsByClass` | `GET /exams/class/:classId` | 查孩子班级考试 |
|
||||||
|
| core-edu | `HomeworkService.ListHomeworkByClass` | `GET /homework/class/:classId` | 查孩子作业 |
|
||||||
|
| core-edu | `GradeService.GetGrade` / `ListGradesByStudent` / `ListGradesByExam` | `GET /grades/student/:childId` / `GET /grades/exam/:examId` | 查孩子成绩 |
|
||||||
|
| core-edu | **`AttendanceService`（proto + REST 双缺失）** | **无** | 查孩子出勤（全局缺失） |
|
||||||
|
| data-ana | `AnalyticsService.GetClassPerformance` / `GetStudentWeakness` / `GetLearningTrend` | **REST 未实现** | 学情分析（004 未列入依赖，待仲裁） |
|
||||||
|
| msg | `NotificationService.ListNotifications` / `MarkAsRead` | `GET /notifications`（msg 服务 P5 才落地） | 家长通知（004 未列入依赖，待仲裁） |
|
||||||
|
| msg 或 iam | **通知偏好配置（proto + REST 双缺失）** | **无** | 配置推送偏好 |
|
||||||
|
|
||||||
|
### 3.2 我暴露的 API 端点（parent-bff 对外）
|
||||||
|
|
||||||
|
> 路由前缀：`/parent`（对齐 teacher-bff 用 `/teacher` 的命名规律）
|
||||||
|
> 网关路径：`/api/v1/parent/*` → api-gateway 剥离 `/api/v1` 后代理到 parent-bff:3010
|
||||||
|
|
||||||
|
| method | path | 聚合下游 | 权限（透传给下游校验） | 说明 |
|
||||||
|
| ------ | ---------------------------------------------- | ------------------ | ------------------------ | --------------------------------------- |
|
||||||
|
| GET | `/parent/dashboard` | iam + core-edu | PARENT_DASHBOARD_READ | 家长首页（含孩子列表 + 近期成绩） |
|
||||||
|
| GET | `/parent/children` | iam | PARENT_CHILDREN_READ | 我的孩子列表 |
|
||||||
|
| POST | `/parent/children/:childId/select` | （BFF 内部状态） | PARENT_CHILDREN_READ | 切换当前选中孩子（sessionId 或 cookie） |
|
||||||
|
| GET | `/parent/children/:childId/exams` | core-edu | PARENT_EXAM_READ | 孩子的考试列表 |
|
||||||
|
| GET | `/parent/children/:childId/homework` | core-edu | PARENT_HOMEWORK_READ | 孩子的作业列表 |
|
||||||
|
| GET | `/parent/children/:childId/grades` | core-edu | PARENT_GRADE_READ | 孩子的成绩列表 |
|
||||||
|
| GET | `/parent/children/:childId/analytics/trend` | data-ana（待仲裁） | PARENT_ANALYTICS_READ | 孩子成绩趋势 |
|
||||||
|
| GET | `/parent/children/:childId/analytics/weakness` | data-ana（待仲裁） | PARENT_ANALYTICS_READ | 孩子薄弱知识点 |
|
||||||
|
| GET | `/parent/notifications` | msg（待仲裁） | PARENT_NOTIFICATION_READ | 家长通知列表 |
|
||||||
|
| POST | `/parent/notifications/:id/read` | msg（待仲裁） | PARENT_NOTIFICATION_READ | 标记已读 |
|
||||||
|
| GET | `/parent/notification-preferences` | msg 或 iam（缺失） | PARENT_PREFERENCE_READ | 通知偏好配置 |
|
||||||
|
| PUT | `/parent/notification-preferences` | msg 或 iam（缺失） | PARENT_PREFERENCE_UPDATE | 更新通知偏好 |
|
||||||
|
|
||||||
|
### 3.3 错误码前缀
|
||||||
|
|
||||||
|
| 前缀 | 用途 | 示例 |
|
||||||
|
| ------------- | ---------------------- | --------------------------------------------------------------------------------- |
|
||||||
|
| `PARENT_BFF_` | parent-bff 自身错误 | `PARENT_BFF_UNAUTHORIZED`、`PARENT_BFF_BAD_GATEWAY`、`PARENT_BFF_CHILD_NOT_BOUND` |
|
||||||
|
| 下游错误透传 | 下游服务错误码原样返回 | `IAM_USER_NOT_FOUND`、`CORE_EDU_GRADE_NOT_FOUND` |
|
||||||
|
|
||||||
|
错误类清单（对齐 teacher-bff application-error.ts + 新增家长特有错误）：
|
||||||
|
|
||||||
|
- `UnauthorizedError(401)` — 缺失 `x-user-id` 头
|
||||||
|
- `BadGatewayError(502)` — 下游服务返回非 ok 或 fetch rejected
|
||||||
|
- `ValidationError(400)` — 入参校验失败（BFF 层 Zod 校验）
|
||||||
|
- `BusinessError(422)` — 业务校验失败（如家长查询的 childId 不在自己绑定列表内）
|
||||||
|
- `NotFoundError(404)` — 资源不存在
|
||||||
|
- `InternalError(500)` — 未捕获异常
|
||||||
|
|
||||||
|
**家长特有错误**：
|
||||||
|
|
||||||
|
- `PARENT_BFF_CHILD_NOT_BOUND(403)` — 家长查询的 childId 未在自己绑定的孩子列表内（DataScope=CHILDREN 越权）
|
||||||
|
|
||||||
|
### 3.4 我订阅的 Kafka 事件（可选，用于实时推送）
|
||||||
|
|
||||||
|
| Topic | 事件 | 消费动作 |
|
||||||
|
| --------------------- | ----------------- | ------------------------------ |
|
||||||
|
| `edu.grade.events` | `grade.recorded` | 推送给家长（孩子成绩发布） |
|
||||||
|
| `edu.homework.events` | `homework.graded` | 推送给家长（孩子作业批改完成） |
|
||||||
|
| `edu.exam.events` | `exam.published` | 推送给家长（考试提醒） |
|
||||||
|
|

## 4. 我的技术栈
|
||||||
|
|
||||||
|
| 维度 | 选型 | 依据 |
|
||||||
|
| ------------ | ------------------------------------ | ----------------------------------------------------------------------------- |
|
||||||
|
| 语言 | TypeScript 5.5+ | 004 §2.1 |
|
||||||
|
| 框架 | NestJS 10 | 004 §2.1，对齐 teacher-bff 模板 |
|
||||||
|
| ORM | **无**（BFF 不访问 DB） | 对齐 teacher-bff，无 repository/schema/dto |
|
||||||
|
| 缓存 | Redis 7（短缓存 5-30s） | 004 §6.2 BFF 混合读策略 |
|
||||||
|
| 会话状态 | Redis（当前选中孩子 childId） | 多子女账户切换，不持久化在 BFF 内存 |
|
||||||
|
| 可观测性日志 | pino | 对齐 classes/teacher-bff |
|
||||||
|
| 可观测性指标 | prom-client（`/metrics` 端点） | 对齐 teacher-bff main.ts |
|
||||||
|
| 可观测性链路 | OpenTelemetry SDK + OTLP exporter | 对齐 teacher-bff tracer.ts |
|
||||||
|
| API 风格 | **HTTP REST**（当前阶段） | 对齐 teacher-bff 现状；与 student-bff 一致，需 coord 仲裁是否统一升级 GraphQL |
|
||||||
|
| 输入校验 | Zod | 对齐 classes/teacher-bff |
|
||||||
|
| 错误处理 | GlobalErrorFilter + ApplicationError | 对齐 classes/teacher-bff |
|
||||||
|
| ESM 模式 | NodeNext + `.js` 后缀 import | 对齐 teacher-bff tsconfig |
|
||||||
|
| 测试框架 | Jest（待定，对齐 classes） | 黄金模板要求测试覆盖率 ≥ 80% |
|
||||||
|
|
||||||
|
### 4.1 关于 GraphQL 的设计决策（待 coord 仲裁）
|
||||||
|
|
||||||
|
与 student-bff §4.1 相同的矛盾，ai04 建议 P4 阶段 parent-bff **先对齐 teacher-bff 现状（REST + fetch + Promise.allSettled）**，与 student-bff 保持一致。此决策需 coord 仲裁。
|
||||||
|
|
||||||
|
### 4.2 关于多子女账户切换的设计
|
||||||
|
|
||||||
|
**问题**：家长账号绑定多个孩子，前端需要知道"当前选中的孩子"。
|
||||||
|
|
||||||
|
**方案对比**：
|
||||||
|
|
||||||
|
| 方案 | 实现 | 优点 | 缺点 |
|
||||||
|
| -------------- | --------------------------------------------------------- | ---------------- | --------------------------------------------------- |
|
||||||
|
| A. 前端管理 | 前端在 URL query 或 localStorage 存 childId，每次请求带上 | BFF 无状态，简单 | 切换后页面状态丢失风险 |
|
||||||
|
| B. BFF Session | Redis 存 `parent:userId:currentChildId`，BFF 读取 | 切换全局生效 | BFF 引入会话状态，违反"无状态服务"约束（004 §12.1） |
|
||||||
|
| C. JWT Claims | iam 在 JWT 中注入 `currentChildId` claim | 与认证一体化 | 切换孩子需重签 JWT，成本高 |
|
||||||
|
|
||||||
|
**ai04 建议**：**方案 A**（前端管理 childId，BFF 无状态），符合 004 §12.1"无状态服务"约束。`POST /parent/children/:childId/select` 端点可选，仅用于记录切换日志（审计），不持久化会话。
|
||||||
|
|
||||||

|
||||||
|
|
||||||
|
## 5. 我的阶段归属
|
||||||
|
|
||||||
|
| 维度 | 内容 |
|
||||||
|
| ------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------- |
|
||||||
|
| 阶段 | **P4 内容分析阶段**（M11-M13） |
|
||||||
|
| 退出标准（pending-features P4） | 教师查看知识图谱前置依赖（Neo4j 秒级返回）→ 学生查看学情诊断（ClickHouse 宽表 5s 内返回）→ CDC 链路延迟 < 5s |
|
||||||
|
| parent-bff 在 P4 的最小交付 | 家长查看孩子成绩 + 学情诊断（双轨读：实时查 core-edu 主库 + 聚合查 data-ana ClickHouse 宽表） |
|
||||||
|
| 依赖上游阶段产出 | P1（api-gateway + classes 黄金模板 + shared-proto）、P2（iam 认证 + teacher-bff BFF 模板）、P3（core-edu 考试/作业/成绩 + student-bff BFF 模式验证） |
|
||||||
|
| P4 同阶段依赖 | content（P4 落地）、data-ana（P4 落地，学情诊断 API） |
|
||||||
|
| P5 阶段扩展 | msg 通知 + push-gateway 推送 + 通知偏好配置 |
|
||||||
|
| 前置阻塞 | iam 必须先补"家长-学生关联查询"接口（见 §7.1） |
|
||||||
|
|
||||||
|
### 5.1 P4 阶段最小可行集合（MVP）
|
||||||
|
|
||||||
|
parent-bff 在 P4 阶段优先级：
|
||||||
|
|
||||||
|
| 优先级 | 端点 | P4 必需 | 说明 |
|
||||||
|
| ------ | -------------------------------------------------- | ------- | ------------------------------------------- |
|
||||||
|
| P0 | `/parent/children` GET | ✅ | 家长核心场景：查孩子列表（依赖 iam 补接口） |
|
||||||
|
| P0 | `/parent/children/:childId/grades` GET | ✅ | 查孩子成绩 |
|
||||||
|
| P0 | `/parent/dashboard` GET | ✅ | 家长首页 |
|
||||||
|
| P1 | `/parent/children/:childId/exams` GET | ✅ | 孩子考试 |
|
||||||
|
| P1 | `/parent/children/:childId/homework` GET | ✅ | 孩子作业 |
|
||||||
|
| P1 | `/parent/children/:childId/analytics/trend` GET | ✅ | 学情趋势（依赖 data-ana P4 落地） |
|
||||||
|
| P1 | `/parent/children/:childId/analytics/weakness` GET | ✅ | 薄弱知识点 |
|
||||||
|
| P2 | `/parent/notifications` GET | ⚠️ 可选 | P5 msg 服务落地后才有意义 |
|
||||||
|
| P2 | `/parent/notification-preferences` GET/PUT | ⚠️ 可选 | P5 落地 |
|
||||||
|
|
||||||
|
### 5.2 与 student-bff 的协同
|
||||||
|
|
||||||
|
parent-bff 与 student-bff 同属 ai04 负责，技术栈完全一致（同语言、同框架、同 BFF 模式）。两者共享：
|
||||||
|
|
||||||
|
- **teacher-bff 克隆模板**：shared/ 目录结构、main.ts、env.ts、health.controller.ts 等基础代码
|
||||||
|
- **聚合模式**：Promise.allSettled 并行调用 + BadGatewayError 错误处理
|
||||||
|
- **可观测性**：pino + prom-client + OTel 三支柱
|
||||||
|
- **错误码前缀**：`PARENT_BFF_` / `STUDENT_BFF_` 仅前缀不同
|
||||||
|
|
||||||
|
**差异点**：
|
||||||
|
|
||||||
|
- parent-bff 多了"多子女账户切换"上下文
|
||||||
|
- parent-bff 多了"DataScope=CHILDREN 越权校验"（家长查询的 childId 必须在自己绑定列表内）
|
||||||
|
- parent-bff 不直接依赖 content / msg / ai（按 004 §4），但实际场景可能需要（待 coord 仲裁）
|
||||||
|
|
||||||

||||||
|
|
||||||
|
## 6. 我需要对齐的黄金模板项（对照 classes 服务）
|
||||||
|
|
||||||
|
> 对照 ai-allocation.md §6 模板第 6 节 + §10 审计模板
|
||||||
|
|
||||||
|
| 对齐项 | classes 黄金模板 | parent-bff 计划 | 备注 |
|
||||||
|
| ------------------------------- | ---------------------------------------- | ------------------------------------------------------------ | ----------------------------------------------------------------- |
|
||||||
|
| 权限装饰器 `@RequirePermission` | ✅ 全部 Controller 方法 | ⚠️ **不对齐** | BFF 不做权限校验（对齐 teacher-bff），透传 `x-user-id` 给下游校验 |
|
||||||
|
| 错误码前缀统一 | ✅ `CLASSES_` | ✅ `PARENT_BFF_` | 对齐 teacher-bff 的 `TEACHER_BFF_` 模式 |
|
||||||
|
| logger（pino） | ✅ `shared/observability/logger.ts` | ✅ 复制 teacher-bff 实现 | service 名改 `parent-bff` |
|
||||||
|
| metrics（prom-client） | ✅ `/metrics` 端点 | ✅ 复制 teacher-bff main.ts 注册方式 | 指标名前缀 `parent_bff_` |
|
||||||
|
| tracer（OpenTelemetry） | ✅ OTLP exporter + auto-instrumentations | ✅ 复制 teacher-bff tracer.ts | serviceName 改 `parent-bff` |
|
||||||
|
| `/healthz` 健康检查 | ✅ liveness | ✅ 复制 teacher-bff | BFF 不查 DB，直接返回 ok |
|
||||||
|
| `/readyz` 健康检查 | ✅ Drizzle `SELECT 1` | ✅ 复制 teacher-bff | BFF 不查 DB，直接返回 ok |
|
||||||
|
| 优雅关闭（SIGTERM） | ✅ LifecycleService 关闭 DB 连接池 | ✅ main.ts 注册 SIGTERM → `app.close()` + `shutdownTracer()` | BFF 无 DB 连接 |
|
||||||
|
| 测试覆盖率 ≥ 80% | ✅ Jest | ⚠️ **待补** | BFF 测试重点是 Service 层聚合逻辑 + DataScope 越权校验 |
|
||||||
|
| Dockerfile 多阶段构建 | ✅ builder + runtime | ✅ 复制 teacher-bff Dockerfile | EXPOSE 改 3010 |
|
||||||
|
| Zod 输入验证 | ✅ Controller 层 `schema.parse(body)` | ✅ Controller 层校验 | 通知偏好更新 body 需 Zod 校验 |
|
||||||
|
| GlobalErrorFilter | ✅ `@Catch()` 全局过滤器 | ✅ 复制 teacher-bff | 注册到 main.ts |
|
||||||
|
| ESM `.js` 后缀 import | ✅ tsconfig NodeNext | ✅ 复制 teacher-bff tsconfig | 所有相对 import 带 `.js` |
|
||||||
|
| `import type` 纯类型导入 | ✅ | ✅ | 对齐 classes 规范 |
|
||||||
|
| 环境变量 Zod 校验 | ✅ `config/env.ts` | ✅ 复制 teacher-bff env.ts | 下游 URL 配置项扩展 |
|
||||||
|
|
||||||
|
### 6.1 与 teacher-bff 模板的差异点（克隆时必须改）
|
||||||
|
|
||||||
|
| 文件 | teacher-bff 现值 | parent-bff 应改为 |
|
||||||
|
| ------------------------------------- | ----------------------------------------------------- | ---------------------------------------------------- |
|
||||||
|
| `package.json` name | `@edu/teacher-bff` | `@edu/parent-bff` |
|
||||||
|
| `src/config/env.ts` `PORT` default | `"3003"` | `"3010"` |
|
||||||
|
| `src/config/env.ts` 下游 URL | IamServiceUrl / ClassesServiceUrl / CoreEduServiceUrl | + DataAnaServiceUrl / MsgServiceUrl（按仲裁结果） |
|
||||||
|
| `src/teacher/` 目录名 | `teacher/` | `parent/` |
|
||||||
|
| `@Controller("teacher")` | `"teacher"` | `"parent"` |
|
||||||
|
| `health.controller.ts` `SERVICE_NAME` | `"teacher-bff"` | `"parent-bff"` |
|
||||||
|
| `application-error.ts` 错误码前缀 | `TEACHER_BFF_` | `PARENT_BFF_` |
|
||||||
|
| `application-error.ts` 新增错误类 | — | `ChildNotBoundError(403)`（DataScope=CHILDREN 越权） |
|
||||||
|
| `metrics.ts` 指标名前缀 | `teacher_bff_` | `parent_bff_` |
|
||||||
|
| `tracer.ts` serviceName | `"teacher-bff"` | `"parent-bff"` |
|
||||||
|
| `logger.ts` service | `"teacher-bff"` | `"parent-bff"` |
|
||||||
|
| `main.ts` 启动日志 | `"Teacher BFF started"` | `"Parent BFF started"` |
|
||||||
|
| `Dockerfile` `EXPOSE` | `3003` | `3010` |

## 7. 风险与依赖（待 coord 仲裁）
|
||||||
|
|
||||||
|
### 7.1 上游依赖缺口（核心阻塞）
|
||||||
|
|
||||||
|
| 风险 | 影响 | 缓解措施 |
|
||||||
|
| ------------------------------------------------------------------------------- | ---------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------- |
|
||||||
|
| **iam 缺失"家长-学生关联查询"接口**（proto + REST + schema 三缺失） | **P0 阻塞**：parent-bff 核心场景无法实现 | 推动 coord 协调 ai02 在 iam 补：1) `iam_student_guardians` 表；2) Repository 查询方法；3) `GET /iam/children` REST 端点；4) proto `GetChildrenByParent` RPC |
|
||||||
|
| pending-features P2 提到 `parent_student_relations` 表，但 iam.schema.ts 未实现 | 表缺失 | 同上，推动 ai02 补表 |
|
||||||
|
| data-ana 服务未实现查询 API（analytics.proto 3 个 method 无 REST 端点） | P4 学情诊断端点无法实现 | 推动 ai06 在 P4 实现 data-ana 查询 API |
|
||||||
|
| content.proto 缺 Chapter/Question 域 | parent-bff 不直接依赖 content，影响较小 | 推动 coord 在 shared-proto 补全（P4 content 服务落地前） |
|
||||||
|
| iam.proto 缺 Viewport/EffectivePermissions | 家长端导航视口 proto 契约不全 | 当前走 REST `/iam/viewports`，proto 补全后切换 |
|
||||||
|
| 出勤（attendance）全局缺失 | 家长无法查孩子出勤 | 推动 coord 在 core_edu.proto 补 Attendance 域（P4 或后续） |
|
||||||
|
| msg 通知偏好配置接口缺失 | 家长通知偏好无法配置 | 推动 ai05 在 msg 服务补接口（P5 阶段） |
|
||||||
|
|
||||||
|
### 7.2 设计决策待仲裁
|
||||||
|
|
||||||
|
| 决策点 | 选项 | ai04 建议 |
|
||||||
|
| ----------------------------------- | ------------------------------------------------------------------------------------------------------ | ----------------------------------------------------------------------------------------------------------------- |
|
||||||
|
| BFF API 风格 | A. REST（对齐 teacher-bff 现状）<br/>B. GraphQL（对齐 004 §11.3 设计意图） | **A**（与 student-bff 保持一致） |
|
||||||
|
| BFF 是否做权限校验 | A. 不校验（对齐 teacher-bff，透传 x-user-id）<br/>B. 加 `@RequirePermission` 装饰器 | **A**（BFF 是聚合层，权限由下游服务校验） |
|
||||||
|
| **DataScope=CHILDREN 越权校验位置** | A. BFF 校验（家长查询的 childId 必须在绑定列表内）<br/>B. 下游服务校验（core-edu 接收 childId 时校验） | **A**（BFF 层校验更早失败，减少下游调用；但需 iam 提供"查询家长绑定孩子列表"接口） |
|
||||||
|
| 多子女账户切换方案 | A. 前端管理 childId（BFF 无状态）<br/>B. BFF Session（Redis 存当前 childId）<br/>C. JWT Claims | **A**（符合 004 §12.1 无状态约束） |
|
||||||
|
| **004 §4 依赖图与实际场景的偏差** | 004 列 parent-bff 仅依赖 iam + core-edu，但家长通知、学情诊断需要 msg + data-ana | **建议扩展依赖**：parent-bff → iam + core-edu + data-ana + msg（与 student-bff 对齐），需 coord 仲裁并更新 004 §4 |
|
||||||
|
| Kafka 事件订阅 | A. P4 不订阅（仅同步聚合）<br/>B. P4 订阅事件推送 | **A**（push-gateway P5 才落地） |
|
||||||
|
| 通知偏好存储位置 | A. msg 服务（通知域内）<br/>B. iam 服务（用户偏好域内） | **A**（通知偏好与通知发送强相关，归 msg 服务） |
|
||||||
|
| 端口分配 | 3010 | 对齐 full-stack-runbook 端口矩阵（3001-3009 已用/将用） |
|
||||||
|
|
||||||
|
### 7.3 跨模块协作需求（需提交 coord 协调）
|
||||||
|
|
||||||
|
| 需求 | 涉及 AI | 协调内容 |
|
||||||
|
| ---------------------------------------------------------------------------------- | -------------- | ------------------------------------------------------------------------------------------------------- |
|
||||||
|
| **iam 新增家长-学生关联接口**（P0 阻塞） | ai02 | 补 `iam_student_guardians` 表 + Repository + `GET /iam/children` 端点 + proto `GetChildrenByParent` RPC |
|
||||||
|
| api-gateway 新增 `/parent` 路由 | ai01 | 在 main.go + config.go 新增 `ParentBffURL` 字段 + 路由块 |
|
||||||
|
| docker-compose.deploy.yml 新增 parent-bff 服务定义 | coord（infra） | 端口 3010，加入 edu-net + edu-shared 网络 |
|
||||||
|
| full-stack-runbook 端口矩阵更新 | coord（docs） | 追加 3010 行 |
|
||||||
|
| 004 架构图状态更新 + 依赖图仲裁 | coord（docs） | parent-bff 状态从"📐 需设计"改为"✅ 已实现"；仲裁是否扩展 parent-bff 依赖到 data-ana + msg |
|
||||||
|
| shared-proto 补全 iam.proto（Viewport/EffectivePermissions/StudentParentRelation） | coord | 推动 ai02 补 proto |
|
||||||
|
| shared-proto 补全 core_edu.proto（Attendance 域） | coord | 推动 ai03 补 proto |
|
||||||
|
| data-ana 实现 analytics.proto 查询 API | ai06 | P4 阶段落地 |
|
||||||
|
| buf.gen.yaml 补 gRPC 插件 | coord | 决定是否在 P4 升级到 gRPC 通信 |
|
||||||
|

**ai04 阶段 1 交付完成，请 coord 审核。审核通过后进入阶段 2（模块架构设计文档）。**
|
||||||
|
|
||||||
|
**特别提示 coord**：parent-bff 存在 P0 阻塞项——iam 缺失"家长-学生关联查询"接口。建议 coord 优先协调 ai02 在 P3 阶段（parent-bff P4 落地前）补全此接口，否则 P4 阶段 parent-bff 无法启动实施。

## 1. 我在架构中的位置
|
||||||
|
|
||||||
|
| 维度 | 内容 |
|
||||||
|
| -------------- | ----------------------------------------------------------------------------- |
|
||||||
|
| 层级 | **L4 BFF 聚合层**（004 §3.1 六层架构） |
|
||||||
|
| 上游调用方 | api-gateway（Go Gin，反向代理 `/api/v1/student/*` → student-bff:3009） |
|
||||||
|
| 下游被调用方 | iam、core-edu、content、data-ana（按 004 §4 服务依赖图） |
|
||||||
|
| 通信方式（入） | HTTP REST（api-gateway → student-bff，当前阶段）；设计意图为 gRPC（004 §4.1） |
|
||||||
|
| 通信方式（出） | HTTP fetch（当前阶段，对齐 teacher-bff 模式）；设计意图为 gRPC（004 §4.1） |
|
||||||
|
| 微前端对接 | student-portal（ai07 负责，P3 阶段）通过 api-gateway 调用 student-bff |
|
||||||
|
| 推送通道 | push-gateway（P5 阶段，WebSocket/SSE 推送考试通知、成绩发布等） |
|
||||||
|
|
||||||
|
**架构定位**（004 §1.1a + §5.4）：
|
||||||
|
|
||||||
|
- 按"使用场景域"分 BFF，student-bff 服务于**学习场景域**，复用角色：学生
|
||||||
|
- 不按角色分 BFF，新角色复用现有 BFF 通过视口差异化
|
||||||
|
- DataScope = **SELF（L0）**：学生只能看自己的数据（004 §5.3）
|
||||||
|
|
||||||

|

|
|
||||||
|
## 2. 我的限界上下文
|
||||||
|
|
||||||
|
### 2.1 我负责什么
|
||||||
|
|
||||||
|
student-bff 是**纯聚合层**，不持有业务状态、不直接访问 DB（对齐 teacher-bff 模式）。职责：
|
||||||
|
|
||||||
|
1. **聚合**：并行调用多个下游业务服务，组装学生视角的复合数据
|
||||||
|
2. **裁剪**：将下游返回的领域数据裁剪为学生端所需的最小字段集
|
||||||
|
3. **协议转换**：对外暴露场景化 HTTP/GraphQL 端点，对内调用下游 REST/gRPC
|
||||||
|
4. **缓存**：聚合结果 Redis 短缓存 5-30s（004 §6.2 BFF 混合读策略）
|
||||||
|
|
||||||
|
### 2.2 我的聚合场景（学生视角）
|
||||||
|
|
||||||
|
| 场景 | 聚合的下游服务 | 用途 |
|
||||||
|
| ------------------ | --------------------------------------------------------------------------- | ------------------------------ |
|
||||||
|
| 学生首页 Dashboard | iam `/iam/me` + core-edu `/homework/class/:classId` + msg `/notifications` | 个人信息 + 待办作业 + 未读消息 |
|
||||||
|
| 即将到来的考试 | core-edu `/exams/class/:classId` | 考试日程提醒 |
|
||||||
|
| 我的作业列表 | core-edu `/homework/class/:classId` | 查看待完成作业 |
|
||||||
|
| 提交作业 | core-edu `/homework/:id/submit` | 学生提交作业答案 |
|
||||||
|
| 我的成绩 | core-edu `/grades/student/:studentId` | 查询历史成绩 |
|
||||||
|
| 消息中心 | msg `/notifications` + `/notifications/:id/read` | 通知列表 + 已读 |
|
||||||
|
| 教材浏览 | content `/textbooks` + `/chapters` | 按章节学习 |
|
||||||
|
| 题库练习 | content `/questions` | 按知识点刷题 |
|
||||||
|
| 学情诊断 | data-ana `/analytics/student/:id/weakness` + `/analytics/student/:id/trend` | 自我掌握度分析 |
|
||||||
|
| AI 答疑 | ai `/ai/chat` + `/ai/stream-chat`（SSE 流式） | 智能答疑辅助 |
|
||||||
|
| 个性化学习路径 | content `/knowledge-points/:id/learning-path` | 基于学情推荐学习路径 |
|
||||||
|
|
||||||
|
### 2.3 我不负责什么（明确边界外）
|
||||||
|
|
||||||
|
| 不负责项 | 归属服务 | 说明 |
|
||||||
|
| -------------- | ------------------------------ | ----------------------------------------------------------------- |
|
||||||
|
| 业务数据持久化 | core-edu / content / msg / iam | BFF 不写 DB |
|
||||||
|
| 权限校验 | 下游业务服务 + iam | BFF 不做权限校验（对齐 teacher-bff），透传 `x-user-id` 让下游校验 |
|
||||||
|
| 用户认证 | iam + api-gateway | JWT 校验在 Gateway，BFF 只读 `x-user-id` 头 |
|
||||||
|
| 领域事件发布 | core-edu / content | BFF 不发布事件，仅可选订阅事件用于实时推送 |
|
||||||
|
| 数据范围过滤 | 下游业务服务 Repository 层 | BFF 透传 userId，下游按 DataScope=SELF 过滤 |
|
||||||
|
| 班级管理 | core-edu（classes 模块） | 学生只读自己所在班级 |
|
||||||
|
| 考试批改 | core-edu | 学生不能批改，只能查看成绩 |
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 3. 我与外部的契约
|
||||||
|
|
||||||
|
### 3.1 我消费的 proto message / 下游接口
|
||||||
|
|
||||||
|
> ⚠️ **重要差距**：当前阶段 BFF→Service 走 HTTP fetch（对齐 teacher-bff 现状），proto 仅作"契约文档"。gRPC 落地需 coord 在 buf.gen.yaml 补 gRPC 插件。
|
||||||
|
|
||||||
|
| 下游服务 | proto service（设计意图） | 当前 REST 端点（实际可用） | 用途 |
|
||||||
|
| ------------------- | ------------------------------------------------------------------------------ | ------------------------------------------------------------ | ------------------------------------ |
|
||||||
|
| iam | `IamService.GetUserInfo` | `GET /iam/me` | 获取学生个人信息 + roles + dataScope |
|
||||||
|
| iam | `IamService.GetViewports`（proto 缺失） | `GET /iam/viewports` | 获取学生端导航视口 |
|
||||||
|
| iam | `IamService.GetEffectivePermissions`（proto 缺失） | `GET /iam/permissions/effective` | 获取有效权限列表 |
|
||||||
|
| classes（core-edu） | `ClassService.GetClass` / `ListClasses` | `GET /classes` / `GET /classes/:id` | 查自己所在班级 |
|
||||||
|
| core-edu | `ExamService.GetExam` / `ListExamsByClass` | `GET /exams/class/:classId` | 查班级考试 |
|
||||||
|
| core-edu | `HomeworkService.GetHomework` / `ListHomeworkByClass` / `SubmitHomework` | `GET /homework/class/:classId` / `POST /homework/:id/submit` | 查作业 + 提交 |
|
||||||
|
| core-edu | `GradeService.GetGrade` / `ListGradesByStudent` | `GET /grades/student/:studentId` | 查自己成绩 |
|
||||||
|
| content | `TextbookService.GetTextbook` / `ListTextbooks` | `GET /textbooks` | 查教材 |
|
||||||
|
| content | `ChapterService`（proto 缺失） | `GET /chapters` / `GET /chapters/:id` | 查章节 |
|
||||||
|
| content | `QuestionService`（proto 缺失） | `GET /questions` | 查题库 |
|
||||||
|
| content | `KnowledgeGraphService.GetLearningPath` | `GET /knowledge-points/:id/learning-path` | 学习路径 |
|
||||||
|
| msg | `NotificationService.ListNotifications` / `MarkAsRead` / `SearchNotifications` | `GET /notifications` / `POST /notifications/:id/read` | 消息中心 |
|
||||||
|
| data-ana | `AnalyticsService.GetStudentWeakness` / `GetLearningTrend` | **REST 未实现** | 学情分析 |
|
||||||
|
| ai | `AiService.Chat` / `StreamChat` / `GenerateQuestion` | **REST 未实现** | AI 答疑 |
|
||||||
|
|
||||||
|
### 3.2 我暴露的 API 端点（student-bff 对外）
|
||||||
|
|
||||||
|
> 路由前缀：`/student`（对齐 teacher-bff 用 `/teacher` 的命名规律，BFF 用角色单数无 `-bff` 后缀）
|
||||||
|
> 网关路径：`/api/v1/student/*` → api-gateway 剥离 `/api/v1` 后代理到 student-bff:3009
|
||||||
|
|
||||||
|
| method | path | 聚合下游 | 权限（透传给下游校验） | 说明 |
|
||||||
|
| ------ | --------------------------------- | -------------------- | ------------------------- | -------------------- |
|
||||||
|
| GET | `/student/dashboard` | iam + core-edu + msg | STUDENT_DASHBOARD_READ | 学生首页聚合 |
|
||||||
|
| GET | `/student/exams` | core-edu | STUDENT_EXAM_READ | 即将到来的考试 |
|
||||||
|
| GET | `/student/homework` | core-edu | STUDENT_HOMEWORK_READ | 我的作业列表 |
|
||||||
|
| POST | `/student/homework/:id/submit` | core-edu | STUDENT_HOMEWORK_SUBMIT | 提交作业 |
|
||||||
|
| GET | `/student/grades` | core-edu | STUDENT_GRADE_READ | 我的成绩 |
|
||||||
|
| GET | `/student/notifications` | msg | STUDENT_NOTIFICATION_READ | 消息列表 |
|
||||||
|
| POST | `/student/notifications/:id/read` | msg | STUDENT_NOTIFICATION_READ | 标记已读 |
|
||||||
|
| GET | `/student/textbooks` | content | STUDENT_CONTENT_READ | 教材列表 |
|
||||||
|
| GET | `/student/chapters/:textbookId` | content | STUDENT_CONTENT_READ | 章节树 |
|
||||||
|
| GET | `/student/questions` | content | STUDENT_CONTENT_READ | 题库（按知识点过滤） |
|
||||||
|
| GET | `/student/analytics/weakness` | data-ana | STUDENT_ANALYTICS_READ | 学情诊断 |
|
||||||
|
| GET | `/student/analytics/trend` | data-ana | STUDENT_ANALYTICS_READ | 学习趋势 |
|
||||||
|
| POST | `/student/ai/chat` | ai | STUDENT_AI_CHAT | AI 答疑（同步） |
|
||||||
|
| POST | `/student/ai/stream-chat` | ai | STUDENT_AI_CHAT | AI 答疑（SSE 流式） |
|
||||||
|
|
||||||
|
### 3.3 错误码前缀
|
||||||
|
|
||||||
|
| 前缀 | 用途 | 示例 |
|
||||||
|
| -------------- | ---------------------- | ----------------------------------------------------- |
|
||||||
|
| `STUDENT_BFF_` | student-bff 自身错误 | `STUDENT_BFF_UNAUTHORIZED`、`STUDENT_BFF_BAD_GATEWAY` |
|
||||||
|
| 下游错误透传 | 下游服务错误码原样返回 | `CLASSES_NOT_FOUND`、`IAM_USER_NOT_FOUND` |
|
||||||
|
|
||||||
|
错误类清单（对齐 teacher-bff application-error.ts）：
|
||||||
|
|
||||||
|
- `UnauthorizedError(401)` — 缺失 `x-user-id` 头
|
||||||
|
- `BadGatewayError(502)` — 下游服务返回非 ok 或 fetch rejected
|
||||||
|
- `ValidationError(400)` — 入参校验失败（BFF 层 Zod 校验）
|
||||||
|
- `InternalError(500)` — 未捕获异常
|
||||||
|
|
||||||
|
### 3.4 我订阅的 Kafka 事件（可选，用于实时推送）
|
||||||
|
|
||||||
|
| Topic | 事件 | 消费动作 |
|
||||||
|
| --------------------- | --------------------------------------- | -------------------------- |
|
||||||
|
| `edu.homework.events` | `homework.assigned` / `homework.graded` | 推送给学生（push-gateway） |
|
||||||
|
| `edu.exam.events` | `exam.published` / `exam.updated` | 考试提醒推送 |
|
||||||
|
| `edu.grade.events` | `grade.recorded` | 成绩发布推送 |
|
||||||
|
|
||||||
|
> ⚠️ Kafka 订阅在 P5 阶段 push-gateway 落地后才有意义，P3 阶段 student-bff 可不消费事件，仅做同步聚合。

## 4. 我的技术栈
|
||||||
|
|
||||||
|
| 维度 | 选型 | 依据 |
|
||||||
|
| ------------ | ------------------------------------ | -------------------------------------------------------------------------------------------------------------------------------------- |
|
||||||
|
| 语言 | TypeScript 5.5+ | 004 §2.1 |
|
||||||
|
| 框架 | NestJS 10 | 004 §2.1，对齐 teacher-bff 模板 |
|
||||||
|
| ORM | **无**（BFF 不访问 DB） | 对齐 teacher-bff，无 repository/schema/dto |
|
||||||
|
| 缓存 | Redis 7（短缓存 5-30s） | 004 §6.2 BFF 混合读策略 |
|
||||||
|
| 可观测性日志 | pino | 对齐 classes/teacher-bff |
|
||||||
|
| 可观测性指标 | prom-client（`/metrics` 端点） | 对齐 teacher-bff main.ts |
|
||||||
|
| 可观测性链路 | OpenTelemetry SDK + OTLP exporter | 对齐 teacher-bff tracer.ts |
|
||||||
|
| API 风格 | **HTTP REST**（当前阶段） | 对齐 teacher-bff 现状；pending-features P2 设计意图为 GraphQL，但 teacher-bff 实际未落地 GraphQL，需 coord 仲裁是否在 student-bff 引入 |
|
||||||
|
| 输入校验 | Zod | 对齐 classes/teacher-bff |
|
||||||
|
| 错误处理 | GlobalErrorFilter + ApplicationError | 对齐 classes/teacher-bff |
|
||||||
|
| ESM 模式 | NodeNext + `.js` 后缀 import | 对齐 teacher-bff tsconfig |
|
||||||
|
| 测试框架 | Jest（待定，对齐 classes） | 黄金模板要求测试覆盖率 ≥ 80% |
|
||||||
|
|
||||||
|
### 4.1 关于 GraphQL 的设计决策（待 coord 仲裁）
|
||||||
|
|
||||||
|
**现状矛盾**：
|
||||||
|
|
||||||
|
- 004 §11.3 BFF 聚合模式图示为 GraphQL Resolver + DataLoader + Redis 缓存
|
||||||
|
- pending-features P2 明确"Teacher BFF（TS/GraphQL）"用 GraphQL Yoga + DataLoader
|
||||||
|
- **实际**：teacher-bff 当前是纯 REST + fetch，无 GraphQL、无 DataLoader
|
||||||
|
- ai-allocation.md §5 ai04 设计重点提到"DataLoader 复用 teacher-bff 模式"
|
||||||
|
|
||||||
|
**ai04 倾向方案**：P3 阶段 student-bff **先对齐 teacher-bff 现状（REST + fetch + Promise.allSettled）**，避免技术栈分裂；若 coord 决策统一升级到 GraphQL，则在 P3 后期或 P4 阶段同步升级 teacher-bff + student-bff + parent-bff 三端。此决策需 coord 仲裁。

## 5. 我的阶段归属
|
||||||
|
|
||||||
|
| 维度 | 内容 |
|
||||||
|
| ------------------------------- | ------------------------------------------------------------------------------------------------------------------------------- |
|
||||||
|
| 阶段 | **P3 核心教学阶段**（M7-M10） |
|
||||||
|
| 退出标准（pending-features P3） | 教师创建考试 → 发布 → 学生作答提交 → 教师批改 → 事件发到 Kafka → 成绩统计更新 → 全链路可观测 |
|
||||||
|
| student-bff 在 P3 的最小交付 | 学生作答作业页面所需 API：`/student/homework` 列表 + `/student/homework/:id/submit` 提交 + `/student/grades` 成绩查看 |
|
||||||
|
| 依赖上游阶段产出 | P1（api-gateway 路由骨架 + classes 黄金模板 + shared-proto）、P2（iam 认证 + teacher-bff BFF 模板 + teacher-portal 微前端骨架） |
|
||||||
|
| P3 同阶段依赖 | core-edu（考试/作业/成绩域 CRUD + Outbox 事件） |
|
||||||
|
| P4 阶段扩展 | 学情诊断查询（双轨读：实时查 core-edu 主库 + 聚合查 data-ana ClickHouse 宽表） |
|
||||||
|
| P5 阶段扩展 | AI 答疑流式响应 + Kafka 事件订阅推送 |
|
||||||
|
|
||||||
|
### 5.1 P3 阶段最小可行集合（MVP）
|
||||||
|
|
||||||
|
student-bff 在 P3 阶段不一定要实现全部 14 个端点，优先级：
|
||||||
|
|
||||||
|
| 优先级 | 端点 | P3 必需 | 说明 |
|
||||||
|
| ------ | ----------------------------------------------------------------- | ------- | ------------------------- |
|
||||||
|
| P0 | `/student/homework` GET | ✅ | 学生作答作业页面核心 |
|
||||||
|
| P0 | `/student/homework/:id/submit` POST | ✅ | 学生作答提交 |
|
||||||
|
| P0 | `/student/grades` GET | ✅ | 成绩查看 |
|
||||||
|
| P0 | `/student/dashboard` GET | ✅ | 学生首页 |
|
||||||
|
| P1 | `/student/exams` GET | ✅ | 考试日程 |
|
||||||
|
| P1 | `/student/notifications` GET | ⚠️ 可选 | P5 msg 服务落地后才有意义 |
|
||||||
|
| P2 | `/student/textbooks` / `/student/chapters` / `/student/questions` | ❌ P4 | content 服务 P4 才落地 |
|
||||||
|
| P2 | `/student/analytics/*` | ❌ P4 | data-ana 学情诊断 P4 |
|
||||||
|
| P2 | `/student/ai/*` | ❌ P5 | ai 服务 P5 |
|
||||||

## 6. 我需要对齐的黄金模板项（对照 classes 服务）
|
||||||
|
|
||||||
|
> 对照 ai-allocation.md §6 模板第 6 节 + §10 审计模板
|
||||||
|
|
||||||
|
| 对齐项 | classes 黄金模板 | student-bff 计划 | 备注 |
|
||||||
|
| ------------------------------- | ---------------------------------------- | ------------------------------------------------------------ | ----------------------------------------------------------------- |
|
||||||
|
| 权限装饰器 `@RequirePermission` | ✅ 全部 Controller 方法 | ⚠️ **不对齐** | BFF 不做权限校验（对齐 teacher-bff），透传 `x-user-id` 给下游校验 |
|
||||||
|
| 错误码前缀统一 | ✅ `CLASSES_` | ✅ `STUDENT_BFF_` | 对齐 teacher-bff 的 `TEACHER_BFF_` 模式 |
|
||||||
|
| logger（pino） | ✅ `shared/observability/logger.ts` | ✅ 复制 teacher-bff 实现 | service 名改 `student-bff` |
|
||||||
|
| metrics（prom-client） | ✅ `/metrics` 端点 | ✅ 复制 teacher-bff main.ts 注册方式 | 指标名前缀 `student_bff_` |
|
||||||
|
| tracer（OpenTelemetry） | ✅ OTLP exporter + auto-instrumentations | ✅ 复制 teacher-bff tracer.ts | serviceName 改 `student-bff` |
|
||||||
|
| `/healthz` 健康检查 | ✅ liveness | ✅ 复制 teacher-bff | BFF 不查 DB，直接返回 ok |
|
||||||
|
| `/readyz` 健康检查 | ✅ Drizzle `SELECT 1` | ✅ 复制 teacher-bff | BFF 不查 DB，直接返回 ok（可选：检查下游服务可达性） |
|
||||||
|
| 优雅关闭（SIGTERM） | ✅ LifecycleService 关闭 DB 连接池 | ✅ main.ts 注册 SIGTERM → `app.close()` + `shutdownTracer()` | BFF 无 DB 连接，仅需关闭 HTTP server + tracer |
|
||||||
|
| 测试覆盖率 ≥ 80% | ✅ Jest | ⚠️ **待补** | BFF 测试重点是 Service 层聚合逻辑 mock 下游 fetch |
|
||||||
|
| Dockerfile 多阶段构建 | ✅ builder + runtime | ✅ 复制 teacher-bff Dockerfile | EXPOSE 改 3009 |
|
||||||
|
| Zod 输入验证 | ✅ Controller 层 `schema.parse(body)` | ✅ Controller 层校验 | 提交作业 body 需 Zod 校验 |
|
||||||
|
| GlobalErrorFilter | ✅ `@Catch()` 全局过滤器 | ✅ 复制 teacher-bff | 注册到 main.ts |
|
||||||
|
| ESM `.js` 后缀 import | ✅ tsconfig NodeNext | ✅ 复制 teacher-bff tsconfig | 所有相对 import 带 `.js` |
|
||||||
|
| `import type` 纯类型导入 | ✅ | ✅ | 对齐 classes 规范 |
|
||||||
|
| 环境变量 Zod 校验 | ✅ `config/env.ts` | ✅ 复制 teacher-bff env.ts | 下游 URL 配置项扩展 |
|
||||||
|
|
||||||
|
### 6.1 与 teacher-bff 模板的差异点（克隆时必须改）
|
||||||
|
|
||||||
|
| 文件 | teacher-bff 现值 | student-bff 应改为 |
|

| `package.json` name | `@edu/teacher-bff` | `@edu/student-bff` |
|
||||||
|
| `src/config/env.ts` `PORT` default | `"3003"` | `"3009"` |
|
||||||
|
| `src/config/env.ts` 下游 URL | IamServiceUrl / ClassesServiceUrl / CoreEduServiceUrl | + ContentServiceUrl / DataAnaServiceUrl / MsgServiceUrl / AiServiceUrl（按聚合需求） |

## 7. 风险与依赖（待 coord 仲裁）
|
||||||
|
|
||||||
|
### 7.1 上游依赖缺口
|
||||||
|
|
||||||
|
| 风险 | 影响 | 缓解措施 |
|
||||||
|
| -------------------------------------------------------------------------- | ----------------------------------- | ----------------------------------------------------------------------------------- |
|
||||||
|
| data-ana 服务未实现查询 API（analytics.proto 3 个 method 无 REST 端点） | P4 学情诊断端点无法实现 | P3 阶段先不实现 `/student/analytics/*`，等 ai06 在 P4 实现 data-ana 查询 API 后再补 |
|
||||||
|
| ai 服务未实现 REST/gRPC 端点 | P5 AI 答疑端点无法实现 | P3/P4 阶段先不实现 `/student/ai/*`，等 ai06 在 P5 实现 ai 服务后再补 |
|
||||||
|
| content.proto 缺 Chapter/Question 域 | P4 教材/题库端点 proto 契约不全 | 推动 coord 在 shared-proto 补全 content.proto |
|
||||||
|
| iam.proto 缺 Viewport/EffectivePermissions | 学生端导航视口 proto 契约不全 | 当前走 REST `/iam/viewports`，proto 补全后切换 |
|
||||||
|
| 出勤（attendance）全局缺失 | 学生端无法查出勤 | 推动 coord 在 core_edu.proto 补 Attendance 域（P3 后期或 P4） |
|
||||||
|
| 学生-家长关联表缺失（pending-features P2 提到 `parent_student_relations`） | 影响 parent-bff，不影响 student-bff | 报告给 coord，由 ai02 在 iam 或 ai03 在 core-edu 补表 |
|
||||||
|
|
||||||
|
### 7.2 设计决策待仲裁
|
||||||
|
|
||||||
|
| 决策点 | 选项 | ai04 建议 |
|
||||||
|
| ------------------ | ------------------------------------------------------------------------------------------------ | ----------------------------------------------------- |
|
||||||
|
| BFF API 风格 | A. REST（对齐 teacher-bff 现状）<br/>B. GraphQL（对齐 004 §11.3 设计意图 + pending-features P2） | **A**（P3 阶段先 REST，避免技术栈分裂；后续统一升级） |
|
||||||
|
| BFF 是否做权限校验 | A. 不校验（对齐 teacher-bff，透传 x-user-id）<br/>B. 加 `@RequirePermission` 装饰器 | **A**（BFF 是聚合层，权限由下游服务校验） |
|
||||||
|
| `/readyz` 检查逻辑 | A. 直接返回 ok（对齐 teacher-bff）<br/>B. 检查下游服务可达性 | **A**（P3 阶段，下游可达性由 Prometheus 监控） |
|
||||||
|
| Kafka 事件订阅 | A. P3 不订阅（仅同步聚合）<br/>B. P3 订阅事件推送 | **A**（push-gateway P5 才落地，P3 无推送通道） |
|
||||||
|
| 端口分配 | 3009 | 对齐 full-stack-runbook 端口矩阵（3001-3008 已用） |
|
||||||
|
|
||||||
|
### 7.3 跨模块协作需求（需提交 coord 协调）
|
||||||
|
|
||||||
|
| 需求 | 涉及 AI | 协调内容 |
|
||||||
|
| ------------------------------------------------------------ | -------------- | --------------------------------------------------------- |
|
||||||
|
| api-gateway 新增 `/student` 路由 | ai01 | 在 main.go + config.go 新增 `StudentBffURL` 字段 + 路由块 |
|
||||||
|
| docker-compose.deploy.yml 新增 student-bff 服务定义 | coord（infra） | 端口 3009，加入 edu-net + edu-shared 网络 |
|
||||||
|
| full-stack-runbook 端口矩阵更新 | coord（docs） | 追加 3009 行 |
|
||||||
|
| 004 架构图状态更新 | coord（docs） | student-bff 状态从"📐 需设计"改为"✅ 已实现" |
|
||||||
|
| shared-proto 补全 content.proto（Chapter/Question） | coord | P4 阶段 content 服务落地前补全 |
|
||||||
|
| shared-proto 补全 iam.proto（Viewport/EffectivePermissions） | coord | 推动 ai02 补 proto |
|
||||||
|
| buf.gen.yaml 补 gRPC 插件 | coord | 决定是否在 P3 升级到 gRPC 通信 |
|
||||||
|

|
## 3. 审计项详解
|
||||||
|
|
||||||
|
### 3.1 权限装饰器 `@RequirePermission` — ⚠️ 不对齐
|
||||||
|
|
||||||
|
**classes 黄金模板**：全部 Controller 方法用 `@RequirePermission(Permissions.XXX)` 装饰，全局 `PermissionGuard` 校验。
|
||||||
|
|
||||||
|
**ai04 服务决策**：**不对齐**。理由：
|
||||||
|
|
||||||
|
- BFF 是纯聚合层，权限由下游业务服务校验（对齐 teacher-bff 现状）
|
||||||
|
- BFF 透传 `x-user-id` 头给下游，下游 Repository 按 DataScope 过滤
|
||||||
|
- parent-bff 在 BFF 层做"DataScope=CHILDREN 越权校验"（家长查询的 childId 必须在绑定列表内），但用普通 Service 层校验，不用装饰器
|
||||||
|
|
||||||
|
**风险**：若 coord 要求 BFF 也加权限装饰器（双重校验），需在 student-bff/parent-bff 引入 `middleware/permission.guard.ts`（复制 classes 实现）。
|
||||||
|
|
||||||
|
### 3.2 错误码前缀 — ✅ 对齐
|
||||||
|
|
||||||
|
| 服务 | 前缀 | 示例 |
|
||||||
|
| ----------- | -------------- | --------------------------------------------------------------------------------- |
|
||||||
|
| student-bff | `STUDENT_BFF_` | `STUDENT_BFF_UNAUTHORIZED`、`STUDENT_BFF_BAD_GATEWAY` |
|
||||||
|
| parent-bff | `PARENT_BFF_` | `PARENT_BFF_UNAUTHORIZED`、`PARENT_BFF_BAD_GATEWAY`、`PARENT_BFF_CHILD_NOT_BOUND` |
|
||||||
|
|
||||||
|
对齐 teacher-bff 的 `TEACHER_BFF_` 模式。
|
||||||
|
|
||||||
|
### 3.3 logger — ✅ 对齐
|
||||||
|
|
||||||
|
复制 teacher-bff `shared/observability/logger.ts`，仅改 `service` 字段：
|
||||||
|
|
||||||
|
- student-bff: `service: 'student-bff'`
|
||||||
|
- parent-bff: `service: 'parent-bff'`
|
||||||
|
|
||||||
|
### 3.4 metrics — ✅ 对齐
|
||||||
|
|
||||||
|
复制 teacher-bff `shared/observability/metrics.ts` + `main.ts` 中 `/metrics` 端点注册，仅改指标名前缀：
|
||||||
|
|
||||||
|
- student-bff: `student_bff_requests_total`、`student_bff_request_duration_seconds`
|
||||||
|
- parent-bff: `parent_bff_requests_total`、`parent_bff_request_duration_seconds`
|
||||||
|
|
||||||
|
### 3.5 tracer — ✅ 对齐
|
||||||
|
|
||||||
|
复制 teacher-bff `shared/observability/tracer.ts`，仅改 `serviceName`：
|
||||||
|
|
||||||
|
- student-bff: `serviceName: 'student-bff'`
|
||||||
|
- parent-bff: `serviceName: 'parent-bff'`
|
||||||
|
|
||||||
|
### 3.6 /healthz — ✅ 对齐
|
||||||
|
|
||||||
|
复制 teacher-bff `shared/health/health.controller.ts`，仅改 `SERVICE_NAME`：
|
||||||
|
|
||||||
|
- student-bff: `service: 'student-bff'`
|
||||||
|
- parent-bff: `service: 'parent-bff'`
|
||||||
|
|
||||||
|
### 3.7 /readyz — ✅ 对齐
|
||||||
|
|
||||||
|
BFF 不查 DB，`/readyz` 直接返回 ok（对齐 teacher-bff）。
|
||||||
|
|
||||||
|
**可选增强**（P3 后期）：检查下游服务可达性（HEAD 请求 iam/core-edu 的 `/healthz`），但 P3 阶段建议先简单返回 ok，下游可达性由 Prometheus 监控。
|
||||||
|
|
||||||
|
### 3.8 优雅关闭 — ✅ 对齐
|
||||||
|
|
||||||
|
复制 teacher-bff `main.ts` 中 SIGTERM 处理：
|
||||||
|
|
||||||
|
```ts
|
||||||
|
process.on("SIGTERM", async () => {
|
||||||
|
await app.close();
|
||||||
|
await shutdownTracer();
|
||||||
|
});
|
||||||
|
```
|
||||||
|
|
||||||
|
BFF 无 DB 连接需关闭（无 LifecycleService），仅需关闭 HTTP server + tracer。
|
||||||
|
|
||||||
|
### 3.9 测试覆盖率 — 🆕 目标 ≥ 80%
|
||||||
|
|
||||||
|
**测试重点**：
|
||||||
|
|
||||||
|
- Service 层聚合逻辑（mock 下游 fetch，验证 Promise.allSettled 容错）
|
||||||
|
- Controller 层入参校验（Zod schema）
|
||||||
|
- 错误处理（BadGatewayError、UnauthorizedError、ValidationError）
|
||||||
|
- parent-bff 特有：DataScope=CHILDREN 越权校验
|
||||||
|
|
||||||
|
**测试框架**：Jest（对齐 classes，待确认 classes 是否已配置 Jest）。
|
||||||
|
|
||||||
|
### 3.10 Dockerfile — ✅ 对齐
|
||||||
|
|
||||||
|
复制 teacher-bff `Dockerfile`（多阶段构建：builder + runtime），仅改 `EXPOSE`：
|
||||||
|
|
||||||
|
- student-bff: `EXPOSE 3009`
|
||||||
|
- parent-bff: `EXPOSE 3010`
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## 4. 与 teacher-bff 模板对比（克隆基线）
|
||||||
|
|
||||||
|
teacher-bff 是已实现的最小 BFF 模板，student-bff/parent-bff 应 1:1 克隆后改造。
|
||||||
|
|
||||||
|
### 4.1 完全复制的部分（无需改动）

### 4.3 teacher-bff 模板的可改进点（ai04 实施时可优化）
|
||||||
|
|
||||||
|
| 改进点 | teacher-bff 现状 | ai04 建议改进 |
|
||||||
|
| ------------ | ----------------------------- | ------------------------------------------------------------ |
|
||||||
|
| 聚合响应类型 | 大量用 `unknown` | 用 Zod schema 推导强类型响应 |
|

|
| 服务 | 总体对齐度 | 阻塞项 | 备注 |
|
||||||
|
| ----------- | ------------ | -------------------------------------- | ---------------------------------------------------------------- |
|

|
| student-bff | 🟢 高（90%） | 无 P0 阻塞 | P3 阶段可直接克隆 teacher-bff 实施，data-ana/ai 端点延后到 P4/P5 |
|
||||||
|
| parent-bff | 🟡 中（70%） | **P0 阻塞：iam 家长-学生关联接口缺失** | 需 coord 协调 ai02 在 P3 阶段补全 iam 接口，否则 P4 无法启动实施 |
|
||||||
|
|
||||||
|
**ai04 阶段 1 审计完成。两份理解确认书 + 本审计表已交付，请 coord 审核。**

|
||||||
|
|
||||||
|
**模块**：student-bff（P3 待实现）、parent-bff（P4 待实现）
|
||||||
|
|
||||||
|
**做了什么**：
|
||||||
|
|
||||||
|
1. 运行 `pnpm run arch:scan` 更新 arch.db（10 TS / 2 Go / 2 Python / 138 proto 契约，12 模块 342 符号）
|
||||||
|
2. 通过 3 个 search subagent 并行探索：classes/teacher-bff/iam 三个 TS NestJS 模板服务结构、shared-proto 全部 8 个 .proto 契约、student-bff/parent-bff 现状与端口/路由预留
|
||||||
|
3. 阅读 README、MIGRATION_GUIDE、004 架构影响地图、pending-features 路线图
|
||||||
|
4. 产出两份模块理解确认书 + 一份服务审计表
|
||||||
|
|
||||||
|
**学到什么**：
|
||||||
|
|
||||||
|
1. **teacher-bff 实际实现与设计意图存在差距**：
|
||||||
|
- 004 §11.3 设计意图为 GraphQL + DataLoader，pending-features P2 明确"Teacher BFF（TS/GraphQL）"
|
||||||
|
- 实际 teacher-bff 是纯 REST + 原生 fetch + Promise.allSettled，无 GraphQL、无 DataLoader
|
||||||
|
- ai04 建议 student-bff/parent-bff 先对齐 teacher-bff 现状（REST），避免技术栈分裂，待 coord 仲裁是否统一升级
|
||||||
|
|
||||||
|
2. **shared-proto 契约与实际 REST 实现存在显著缺口**：
|
||||||
|
- proto 包名用 `next_edu_cloud.*` 而非项目规则要求的 `edu.*`（8 个文件全不合规）
|
||||||
|
- buf.gen.yaml 只配置了 protocolbuffers 序列化插件，**无 gRPC 插件**，proto 目前仅作"契约文档"
|
||||||
|
- iam REST 已暴露 viewports/permissions/effective/roles 端点，但 proto 完全缺失
|
||||||
|
- content REST 已实现 chapters/questions CRUD，但 proto 完全缺失
|
||||||
|
- data-ana/ai 服务的 proto 已定义但 REST 端点未实现
|
||||||
|
|
||||||
|
3. **parent-bff 存在 P0 阻塞项**：
|
||||||
|
- iam 缺失"家长-学生关联查询"接口（proto + REST + schema 三缺失）
|
||||||
|
- pending-features P2 提到 `parent_student_relations` 表，但 iam.schema.ts 未实现
|
||||||
|
- 需 coord 协调 ai02 在 P3 阶段补全，否则 P4 parent-bff 无法启动
|
||||||
|
|
||||||
|
4. **004 §4 服务依赖图与实际场景存在偏差**：
|
||||||
|
- 004 列 parent-bff 仅依赖 iam + core-edu
|
||||||
|
- 但家长通知、学情诊断场景需要 msg + data-ana
|
||||||
|
- 需 coord 仲裁是否扩展 parent-bff 依赖
|
||||||
|
|
||||||
|
5. **端口/路由预留情况**：
|
||||||
|
- student-bff=3009、parent-bff=3010 可用（3001-3008 已用）
|
||||||
|
- api-gateway 未预留 `/student`、`/parent` 路由（需 ai01 协调）
|
||||||
|
- pnpm-workspace.yaml glob `services/*` 自动覆盖新目录
|
||||||
|
- commitlint scope-enum + CODEOWNERS 已预留 student-bff/parent-bff
|
||||||
|
|
||||||
|
6. **BFF 克隆模板策略**：
|
||||||
|
- teacher-bff 是最小 BFF 模板，shared/ 目录结构与 classes 完全一致
|
||||||
|
- BFF 特征：无 DB、无 repository/schema/dto、无 PermissionGuard、无 LifecycleService
|
||||||
|
- student-bff/parent-bff 可 1:1 克隆 teacher-bff 后改造（11 处需改名）
|
||||||
|
|
||||||
|
**下次注意**：
|
||||||
|
|
||||||
|
1. 阶段 2 设计文档需等 coord 审核阶段 1 后再产出
|
||||||
|
2. 实施前需推动 coord 协调 ai02 补全 iam 家长-学生关联接口（P0 阻塞）
|
||||||
|
3. 实施前需推动 coord 协调 ai01 在 api-gateway 预留 `/student`、`/parent` 路由
|
||||||
|
4. proto 包名合规性（`next_edu_cloud.*` → `edu.*`）需 coord 仲裁是否迁移
|
||||||
|
5. buf.gen.yaml 是否补 gRPC 插件需 coord 决策
|
||||||

|
| 场景 | 技术/规则 |
|
||||||
|
| ----------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------- |
|
||||||
|
| BFF 服务克隆 teacher-bff 模板 | 复制 shared/ + 改 11 处命名（package.json/env.ts/Controller/SERVICE_NAME/错误码前缀/指标名前缀/tracer serviceName/logger service/Dockerfile EXPOSE） |
|
||||||
|
| BFF 不做权限校验 | 透传 `x-user-id` 给下游服务校验（对齐 teacher-bff），BFF 无 PermissionGuard |
|
||||||
|
| BFF 聚合用 Promise.allSettled | Dashboard 类聚合容错（部分失败返回 null）；单依赖查询用 throw BadGatewayError 快速失败 |
|
||||||
|
| BFF 无 DB 依赖 | /readyz 直接返回 ok，无 LifecycleService，无 closeDb() |
|
||||||
|
| 新服务端口分配 | NestJS 服务按 3001-3008 顺序分配，student-bff=3009、parent-bff=3010 |
|
||||||
|
| api-gateway 路由前缀命名 | BFF 用角色单数无 `-bff` 后缀（teacher-bff → `/teacher`，student-bff → `/student`） |
|
||||||
|
| proto 包名不合规 | 当前用 `next_edu_cloud.*`，规则要求 `edu.*`，8 个文件全不合规，待 coord 仲裁迁移 |
|
||||||
|
| buf.gen.yaml 缺 gRPC 插件 | 当前只配置 protocolbuffers 序列化，proto 仅作"契约文档"，gRPC 通信未落地 |
