**结论:** student-bff v2 全部 P0/P1 工作已完成并验证通过。60 个 GraphQL 操作36 Query + 24 Mutation全部注册并可响应。
---
## 1. student-bff v2 完成项详情
### 1.1 P0index.ts 装配 extended resolvers
**修复前:** `index.ts` 仅装配 11 个基础 resolver22 个 extended Query + 21 个 extended Mutation 已实现但未导入。
**修复后:**
```typescript
import { extendedQueriesResolvers } from "./extended-queries.resolver.js";
import { extendedMutationsResolvers } from "./extended-mutations.resolver.js";
export const studentBffResolvers = {
Query: {
...(authResolvers.Query ?? {}),
// ... 其他基础 resolver
...(extendedQueriesResolvers.Query ?? {}), // ✅ 新增
},
Mutation: {
...(homeworkResolvers.Mutation ?? {}),
...(notificationsResolvers.Mutation ?? {}),
...(extendedMutationsResolvers.Mutation ?? {}), // ✅ 新增
},
Subscription: {
...(aiStreamResolvers.Subscription ?? {}),
},
};
```
**验证:** GraphQL introspection 查询返回 36 Query + 24 Mutation = 60 操作。
### 1.2 P0shared-ts schema 补全
**修复前:** `student-bff.schema.graphql` 仅 822 行,定义 15 Query + 2 Mutation + 1 Subscription。
**修复后:** 1648 行,定义 36 Query + 24 Mutation + 1 Subscription包含所有 input type / enum / payload type。
### 1.3 P1myAttendance resolver 实现
调用 `core-edu.AttendanceService.ListAttendanceByStudent`B4 强制 `userId = studentId`DataScope SELF
### 1.4 P1startPracticeSession 类型修正
从 Query 移到 Mutation语义为创建会话
### 1.5 P0RecordExamViolationInput schema 类型对齐
schema 引用 `RecordExamViolationInput` 但实际定义为 `RecordViolationInput`,已修正为 `recordExamViolation(input: RecordViolationInput!)`
### 1.6 P0Dockerfile 修复
**问题:** 原 Dockerfile 的 COPY 路径未包含 `services/student-bff/` 前缀,且 runtime stage 使用 `--ignore-workspace` 导致 `@edu/shared-ts` 无法解析。
**修复:** 对齐 teacher-bff 模式:
- Builder stage复制 workspace 配置 + shared-proto + shared-ts + student-bff使用 `--filter @edu/student-bff...` 过滤安装(避免 scripts/arch-scan 的 better-sqlite3 原生编译),先构建 shared-ts 再构建 student-bff
- Runtime stage保留 workspace 结构,`pnpm install --prod --filter @edu/student-bff... --ignore-scripts`,复制 shared-ts dist 产物
### 1.7 P0shared-ts pino NodeNext 类型修复
**问题:** pino 在 NodeNext + ESM 模式下 default import 丢失 callable 签名declaration merging 失效)。
**修复:** 通过 namespace import + 显式类型断言恢复可调用性:
```typescript
import * as pinoNs from "pino";
import type { Logger as PinoLogger, LoggerOptions } from "pino";
type PinoFn = (options?: LoggerOptions | unknown) => PinoLogger;
const pino = ((pinoNs as unknown as { default: PinoFn }).default ??
(pinoNs as unknown as PinoFn)) as PinoFn;
```
同时修复 `src/bff/downstream-client.ts:351` 的 IteratorResult 类型窄化问题。

## 6. 联调就绪状态
```
student-portal ──✅──> api-gateway ──✅──> student-bff ──✅──> [60 操作全部注册]
├──✅──> core-edu (40 RPC 就绪)
├──✅──> iam (15 RPC 就绪)

└──❌──> docker-compose 未配置
```
**结论:** student-bff 自身已完全就绪v2 全部 P0/P1 已修复并验证)。待 SRE AI 配置 docker-compose + content/data-ana/ai 服务确认 RPC 后,可进行端到端联调。
---
## 7. 已知限制
| # | 限制 | 说明 |
| --- | ---------------------------------------------- | ---------------------------------------------------------------------------------------------- |
| 1 | Dockerfile 使用 `--filter @edu/student-bff...` | 过滤掉 scripts/arch-scan 的 better-sqlite3 原生编译依赖,避免 alpine 缺少 build-essential |
| 2 | Dockerfile 需先构建 shared-ts | student-bff 运行时依赖 `@edu/shared-ts/bff` 的 dist 产物Dockerfile 已包含 shared-ts 构建步骤 |
| 3 | shared-ts pino 需 namespace import | pino 在 NodeNext + ESM 下 default import 丢失 callable 签名,已通过 namespace import 修复 |
| 4 | Kafka 未启动时 EventSubscriber 软失败 | 服务正常启动,但实时事件推送(通知/AI 流式响应)不工作 |
| 5 | 下游 gRPC 未就绪时进入降级模式 | 所有 Query 返回 `degraded=true` + 空数据;所有 Mutation 返回 `success=false` + BAD_GATEWAY |
| 6 | DEV_MODE=true 时跳过 B4 越权校验 | 生产环境必须 `DEV_MODE=false`,由 api-gateway 注入 `x-user-id` header |

## 1. 概述
student-bff 已完成全部 35 Query + 23 Mutation + 1 Subscription 的 schema 与 resolver 实现Docker 镜像本地构建与运行验证通过(`MOCK_UPSTREAM=false`)。下游 gRPC 服务未启动时BFF 进入降级模式(方案 B返回 `degraded: true` + `degradedReason` + `degradedFields`
**本地 Docker 测试结果2026-07-13**
- ✅ 镜像构建成功(`edu/student-bff:test`
- ✅ 容器启动正常(端口 3009NestFactory + GraphQL Yoga 初始化完成)
-`/healthz` 返回 200
-`MOCK_UPSTREAM=false`,下游未启动时进入降级模式
-`serverTime` Query 返回本地时间(无下游依赖)
-`myProfile` Query 返回 `degraded=true`,原因为 `DOWNSTREAM_FAILURE: iam.GetUserProfile failed after 3 attempts`
-`mySchedule` Query 返回空 items + `degraded=true`
-`markAsRead` Mutation 返回 `success=false` + `error.code=BFF_STUDENT_BAD_GATEWAY`
-`createLeaveRequest` Mutation 返回 `success=false` + `error.code=BFF_STUDENT_BAD_GATEWAY`
- ✅ B4 越权防御生效:无 `x-user-id` header 时返回 401 UnauthorizedError

## 5. 联调顺序建议
1. **ai06** 完成 iam gRPCGetUserProfile / UpdateProfile / ChangePassword
2. **ai08** 完成 core-edu gRPCGetExam / SubmitExam / GetHomework / GetScheduleByStudent 等 10 个)
3. **ai09** 完成 content gRPC8 个选修/教案/课程计划相关)
4. **ai12** 完成 data-ana gRPC8 个学情分析相关)
5. **ai10** 完成 msg gRPC6 个通知/公告相关)
6. **ai01** 完成 api-gateway `/api/v1/student/graphql` 路由 + JWT 注入
7. **ai11** 完成 ai gRPC StreamAIChatP1
8. **ai13** 完成 push-gateway WebSocketP1
9. 端到端联调student-portal → api-gateway → student-bff → 6 个下游 gRPC 服务)

## 6. 已知限制
| # | 限制 | 说明 |
| --- | ------------------------------------- | ------------------------------------------------------------------------------------------ |
| 1 | Kafka 未启动时 EventSubscriber 软失败 | 服务正常启动,但实时事件推送(通知/AI 流式响应)不工作 |
| 2 | 下游 gRPC 未就绪时进入降级模式 | 所有 Query 返回 `degraded=true` + 空数据;所有 Mutation 返回 `success=false` + BAD_GATEWAY |
| 3 | DEV_MODE=true 时跳过 B4 越权校验 | 生产环境必须 `DEV_MODE=false`,由 api-gateway 注入 `x-user-id` header |
| 4 | pino-pretty 仅 devDependencies | 生产环境 `NODE_ENV=production` 时不启用 pino-pretty transport输出结构化 JSON |
| 5 | OTEL_EXPORTER_OTLP_ENDPOINT 未配置 | Tracer 被禁用,需配置 OTLP endpoint 启用全链路追踪 |
