|
||||
|
||||
---
|
||||
|
||||
## 1. 概述
|
||||
|
||||
push-gateway 是 Edu 平台的实时 WebSocket 推送基础设施(L3 网关层,端口 8081),负责维护用户在线连接、接收 msg 服务通过 HTTP `/internal/*` 和 Kafka 推送的消息、并通过 WebSocket 实时投递给在线客户端。
|
||||
|
||||
**v2 核心目标**:对齐 ARB-013 Kafka topic 命名规范和 msg 服务的 API 契约,消除 v1 中存在的 4 个不一致点。
|
||||
|
||||
---
|
||||
|
||||
## 2. v2 完成的工作(API 契约对齐)
|
||||
|
||||
### 2.1 Kafka topic 对齐(ARB-013)
|
||||
|
||||
| 项 | v1 | v2 | 状态 |
|
||||
| ---------- | -------------------------------- | ---------------------------------------------- | ---- |
|
||||
| 消费 topic | `edu.notification.requested` | `edu.notify.notification.sent` | ✅ |
|
||||
| 命名规范 | 旧命名(违反 ARB-013) | `edu.<domain>.<aggregate>.<action>` | ✅ |
|
||||
| DLQ topic | `edu.notification.requested.dlq` | `edu.notify.notification.sent.dlq`(自动派生) | ✅ |
|
||||
|
||||
**修改文件**:
|
||||
|
||||
- `internal/config/config.go`:`KAFKA_NOTIFICATION_TOPIC` 默认值改为 `edu.notify.notification.sent`
|
||||
- `internal/kafkaconsumer/consumer.go`:包注释更新,metric label 使用 `event.EventType`(而非硬编码 "notification.requested")
|
||||
- `internal/config/config_test.go`:断言更新为新 topic 名
|
||||
|
||||
### 2.2 鉴权头对齐
|
||||
|
||||
| 项 | v1 | v2 | 状态 |
|
||||
| -------- | -------------------- | -------------------------------------------------------------------- | ---- |
|
||||
| 规范头名 | `X-Internal-Token` | `X-Internal-Key`(ARB-013 对齐 msg) | ✅ |
|
||||
| 向后兼容 | — | 同时接受 `X-Internal-Token`(legacy alias) | ✅ |
|
||||
| 环境变量 | `INTERNAL_API_TOKEN` | `PUSH_INTERNAL_TOKEN`(canonical)+ `INTERNAL_API_TOKEN`(fallback) | ✅ |
|
||||
|
||||
**修改文件**:
|
||||
|
||||
- `internal/ws/handler.go`:
|
||||
- `internalTokenHeader` 常量改为 `X-Internal-Key`
|
||||
- 新增 `legacyInternalTokenHeader = "X-Internal-Token"` 兼容别名
|
||||
- `checkInternalToken()` 依次尝试两个头
|
||||
- `internal/config/config.go`:优先读取 `PUSH_INTERNAL_TOKEN`,为空时回退到 `INTERNAL_API_TOKEN`
|
||||
|
||||
### 2.3 请求体字段命名对齐
|
||||
|
||||
| 项 | v1 | v2 | 状态 |
|
||||
| ------------ | ------------------------ | --------------------------------------------------------- | ---- |
|
||||
| 用户 ID 字段 | `user_id`(snake_case) | `userId`(camelCase,msg canonical)+ `user_id`(legacy) | ✅ |
|
||||
| 其他字段 | `event` / `data` / `ttl` | 保持不变 | ✅ |
|
||||
|
||||
**修改文件**:
|
||||
|
||||
- `internal/ws/handler.go` `PushHandler()`:
|
||||
- 结构体同时定义 `UserID json:"userId"` 和 `UserIDLeg json:"user_id"`
|
||||
- 绑定后若 `UserID` 为空则回退到 `UserIDLeg`
|
||||
|
||||
### 2.4 环境变量对齐
|
||||
|
||||
| v1 环境变量 | v2 规范环境变量 | 兼容性 |
|
||||
| --------------------------------------------------------------- | ----------------------------------------------------------------- | ----------------------------- |
|
||||
| `INTERNAL_API_TOKEN` | `PUSH_INTERNAL_TOKEN` | v1 变量作为 fallback 别名保留 |
|
||||
| `KAFKA_NOTIFICATION_TOPIC`(默认 `edu.notification.requested`) | `KAFKA_NOTIFICATION_TOPIC`(默认 `edu.notify.notification.sent`) | 环境变量名不变,默认值更新 |
|
||||
|
||||
**修改文件**:
|
||||
|
||||
- `infra/docker-compose.deploy.yml`:push-gateway 段使用 `PUSH_INTERNAL_TOKEN`(支持 `${PUSH_INTERNAL_TOKEN:-${INTERNAL_API_TOKEN:-edu-internal-token}}` 回退链)
|
||||
- `infra/deploy.env.example`:`PUSH_INTERNAL_TOKEN` 为规范变量,`INTERNAL_API_TOKEN` 标注为兼容别名
|
||||
|
||||
### 2.5 部署配置更新
|
||||
|
||||
| 文件 | 修改内容 |
|
||||
| --------------------------------- | ---------------------------------------------------------------------------------------- |
|
||||
| `infra/docker-compose.deploy.yml` | `KAFKA_NOTIFICATION_TOPIC: edu.notify.notification.sent`;`PUSH_INTERNAL_TOKEN` 带回退链 |
|
||||
| `infra/deploy.env.example` | 新增 `PUSH_INTERNAL_TOKEN`,保留 `INTERNAL_API_TOKEN` 作为兼容别名(留空) |
|
||||

|
||||
|
||||
## 3. 本地 Docker 验证结果(2026-07-14 v2)
|
||||
|
||||
测试环境:本地 Docker Desktop,`edu-full_default` 网络,接入真实 edu-kafka / edu-redis / edu-iam-test。
|
||||
|
||||
```
|
||||
镜像:edu/push-gateway:test
|
||||
容器:edu-push-gateway-test(DEV_MODE=true, PUSH_INTERNAL_TOKEN=test-internal-token-v2)
|
||||
网络:edu-full_default(直连 edu-kafka:29092 / edu-redis:6379 / edu-iam-test:3002)
|
||||
```
|
||||
|
||||
| 验证项 | 结果 | 说明 |
|
||||
| --------------------------------------- | ---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
|
||||
| `go vet ./...` | ✅ | 零警告 |
|
||||
| `go build ./...` | ✅ | 零错误 |
|
||||
| `go test ./...` | ✅ | config/hub/ws 全部通过(含新增 `TestLoadProdModeLegacyToken`) |
|
||||
| Docker 镜像构建 | ✅ | `edu/push-gateway:test` 构建成功 |
|
||||
| `/healthz` | ✅ | `{"service":"push-gateway","status":"ok"}` |
|
||||
| `/readyz` | ✅ | `degraded:false`,kafka+redis 均 ok |
|
||||
| 容器日志确认 topic | ✅ | `kafka_topic=edu.notify.notification.sent` |
|
||||
| **v2 契约:X-Internal-Key + userId** | ✅ | `POST /internal/push` 返回 `{"success":true}` |
|
||||
| **v1 兼容:X-Internal-Token + user_id** | ✅ | 旧调用方式仍正常工作 |
|
||||
| **Kafka 全链路:新 topic → WS** | ✅ | 发布到 `edu.notify.notification.sent` → WebSocket 客户端收到消息 |
|
||||
| **考试事件透传(3 类)** | ✅ | ExamExtended / ExamForceSubmitted / ExamQuestionReordered 全部经 Kafka → WS 投递成功 |
|
||||
| Prometheus metrics | ✅ | `push_gateway_kafka_consumed_total{topic="edu.notify.notification.sent"}` 计数正确;`push_gateway_messages_pushed_total{event="ExamExtended",result="delivered"}` 等标签正确 |
|
||||
|
||||
### 3.1 测试脚本
|
||||
|
||||
| 脚本 | 用途 |
|
||||
| ---------------------------------------------------- | -------------------------------------------------------------------------------------------- |
|
||||
| `services/push-gateway/scripts/test-kafka-ws.mjs` | 验证单条 Kafka 消息经 `edu.notify.notification.sent` topic 到达 WebSocket 客户端 |
|
||||
| `services/push-gateway/scripts/test-exam-events.mjs` | 验证 3 类考试事件(ExamExtended/ExamForceSubmitted/ExamQuestionReordered)的 event_type 透传 |
|
||||
|
||||
运行方式(需在仓库根目录):
|
||||
|
||||
```bash
|
||||
# 前置:push-gateway 容器已启动并接入 edu-full_default 网络
|
||||
node services/push-gateway/scripts/test-kafka-ws.mjs
|
||||
node services/push-gateway/scripts/test-exam-events.mjs
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 4. 上游依赖(调用 push-gateway 的模块)
|
||||
|
||||
### 4.1 4 个前端 Portal(teacher/student/parent/admin)— P0
|
||||
|
||||
| Portal | WebSocket 接入状态 | v2 新增工作 | 状态 |
|
||||
| -------------- | --------------------------------------------- | ----------- | ---- |
|
||||
| teacher-portal | ✅ 已接入(`useNotificationsWebSocket` hook) | 无 | ✅ |
|
||||
| student-portal | ✅ 已接入(考试事件监听) | 无 | ✅ |
|
||||
| parent-portal | ✅ 已接入 | 无 | ✅ |
|
||||
| admin-portal | ✅ 已接入 | 无 | ✅ |
|
||||
|
||||
**说明**:4 个 portal 在 v1 阶段已完成 WebSocket 接入,使用 `?token=<jwt>` query param 鉴权。v2 的 API 契约变更(Kafka topic / 鉴权头 / 请求体字段)对 portal 透明,无需 portal 侧改动。
|
||||
|
||||
### 4.2 3 个 BFF(teacher-bff / student-bff / parent-bff)— P1
|
||||
|
||||
| BFF | 依赖 push-gateway 的方式 | v2 新增工作 | 状态 |
|
||||
| ----------- | ------------------------------------- | ----------- | ---- |
|
||||
| teacher-bff | 无直接依赖(BFF 不调用 push-gateway) | 无 | ✅ |
|
||||
| student-bff | 无直接依赖(BFF 不调用 push-gateway) | 无 | ✅ |
|
||||
| parent-bff | 无直接依赖(BFF 不调用 push-gateway) | 无 | ✅ |
|
||||
|
||||
**说明**:BFF 层不直接调用 push-gateway。推送由 msg 服务通过 HTTP `/internal/push` 或 Kafka 发起,push-gateway 负责投递到 portal 的 WebSocket。
|
||||
|
||||
---
|
||||
|
||||
## 5. 下游依赖(push-gateway 调用的模块)
|
||||
|
||||
### 5.1 iam 服务(ai06 负责)— P0
|
||||
|
||||
| 依赖项 | 用途 | 状态 |
|
||||

|
||||
|
||||
**环境变量**:`JWKS_URL=http://iam:3002/v1/iam/.well-known/jwks.json`
|
||||
|
||||
**说明**:shared-go/jwks Fetcher 每 5 分钟刷新 JWKS 缓存。DevMode 接受 `dev-token` 旁路 JWT 验签。
|
||||
|
||||
### 5.2 msg 服务(ai10 负责)— P0
|
||||
|
||||
| 依赖项 | 用途 | 状态 |
|
||||
| -------------------------------------------- | ------------------------------------------------- | --------- |
|
||||
| HTTP `POST /internal/push` | 定向推送(msg → push-gateway) | ✅ 已对齐 |
|
||||
| Kafka topic `edu.notify.notification.sent` | 事件驱动推送(msg Outbox → Kafka → push-gateway) | ✅ 已对齐 |
|
||||
| 鉴权头 `X-Internal-Key: PUSH_INTERNAL_TOKEN` | /internal/* API 鉴权 | ✅ 已对齐 |
|
||||
| 请求体 `{ userId, event, data }` | camelCase 字段命名 | ✅ 已对齐 |
|
||||
|
||||
**环境变量**:
|
||||
|
||||
- push-gateway 侧:`PUSH_INTERNAL_TOKEN`(canonical)/ `INTERNAL_API_TOKEN`(fallback)
|
||||
- msg 侧:`PUSH_INTERNAL_TOKEN`(已对齐)
|
||||
|
||||
**v2 对齐结果**:4 个不一致点(Kafka topic / 鉴权头 / 请求体字段 / 环境变量)全部修复,push-gateway 同时保持对 v1 调用方式的向后兼容。
|
||||
|
||||
### 5.3 Redis(基础设施)— P0
|
||||
|
||||
| 依赖项 | 用途 | 状态 |
|
||||

|
||||
|
||||
**环境变量**:`REDIS_URL=redis://edu-redis:6379/0`
|
||||
|
||||
### 5.4 Kafka(基础设施)— P0
|
||||
|
||||
| 依赖项 | 用途 | 状态 |
|
||||
| ----------------- | ----------------------------------------- | --------- |
|
||||
| `edu-kafka:29092` | 消费 `edu.notify.notification.sent` topic | ✅ 已就绪 |
|
||||
|
||||
**环境变量**:
|
||||
|
||||

|
||||
- `KAFKA_NOTIFICATION_TOPIC=edu.notify.notification.sent`(ARB-013)
|
||||
- `KAFKA_CONSUMER_GROUP=push-gateway`
|
||||
|
||||
### 5.5 OTel Collector(基础设施)— P1
|
||||

||||
| 依赖项 | 用途 | 状态 |
|
||||
| ---------------------------- | --------------- | --------- |
|
||||
| `http://otel-collector:4318` | OTLP trace 上报 | ⏳ 待部署 |
|
||||
|
||||
**环境变量**:`OTEL_EXPORTER_OTLP_ENDPOINT=http://otel-collector:4318`
|
||||
|
||||
**说明**:未配置时 push-gateway 跳过 trace 上报,不影响功能。
|
||||
|
||||
---
|
||||
|
||||
## 6. 待协调事项(需上下游配合)
|
||||
|
||||
### 6.1 core-edu 考试事件发布(下游阻塞 student-portal)
|
||||
|
||||
| 项 | 详情 |
|
||||
| ------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------ |
|
||||
| 阻塞方 | core-edu(ai07) |
|
||||
| 影响方 | student-portal / student-bff |
|
||||
| 问题 | student-portal 期望接收 `ExamExtended` / `ExamForceSubmitted` / `ExamQuestionReordered` 三类考试事件,但这些事件在 core-edu 源码中未找到发布逻辑 |
|
||||
| 期望流程 | core-edu Outbox publisher → Kafka `edu.notify.notification.sent` → push-gateway → student-portal WebSocket |
|
||||
| push-gateway 侧状态 | ✅ 已验证可消费这三类事件并透传到 WebSocket(见 §3 测试结果) |
|
||||
| 协调动作 | 请 core-edu 在考试相关业务逻辑中发布这三类事件到 `edu.notify.notification.sent` topic |
|
||||
|
||||
### 6.2 msg 服务 Outbox 发布 topic 对齐(待确认)
|
||||
|
||||
| 项 | 详情 |
|
||||
| ------------------- | ---------------------------------------------------------------------------------------------------------------------------- |
|
||||
| 阻塞方 | msg(ai10) |
|
||||
| 问题 | 需确认 msg 的 Outbox publisher 已将发布 topic 从 `edu.notification.requested` 改为 `edu.notify.notification.sent`(ARB-013) |
|
||||
| push-gateway 侧状态 | ✅ 已消费 `edu.notify.notification.sent` |
|
||||
| 协调动作 | 请 msg 确认 Outbox `TOPIC_MAP` 中 `NotificationSent` 事件映射到 `edu.notify.notification.sent`;如仍发往旧 topic,需更新 |
|
||||
|
||||
### 6.3 生产环境环境变量迁移(部署时)
|
||||
|
||||
| 项 | 详情 |
|
||||
| ------------------- | -------------------------------------------------------------------------------------------------------------- |
|
||||
| 阻塞方 | SRE AI / 人类决策者 |
|
||||
| 问题 | 生产环境需将 `INTERNAL_API_TOKEN` 迁移为 `PUSH_INTERNAL_TOKEN`(或在 deploy.env 中同时设置两者) |
|
||||
| push-gateway 侧状态 | ✅ 支持双环境变量(`PUSH_INTERNAL_TOKEN` 优先,`INTERNAL_API_TOKEN` 回退) |
|
||||
| 协调动作 | 部署时在 `infra/security/secrets.example.env` 或 K8s Secret 中设置 `PUSH_INTERNAL_TOKEN`;旧变量可保留作为兼容 |
|
||||
|
||||

|
||||
|
||||
## 9. API 契约(v2)
|
||||
|
||||
### 9.1 WebSocket 端点
|
||||
|
||||
```
|
||||
GET /ws?token=<jwt>
|
||||
```
|
||||
|
||||
- 鉴权:JWT RS256(via iam JWKS)或 DevMode `dev-token`
|
||||
- 消息格式:`{ "type": "message", "event": "<event_type>", "data": {...}, "timestamp": "<RFC3339>" }`
|
||||
- 心跳:RFC 6455 Ping/Pong(30s 间隔,60s 空闲超时)
|
||||
|
||||
### 9.2 内部 HTTP API
|
||||
|
||||
| 方法 | 路径 | 鉴权头 | 请求体 | 响应 |
|
||||
| ---- | --------------------------- | ------------------------- | ------------------------------- | ---------------------------------------------------- |
|
||||
| POST | `/internal/push` | `X-Internal-Key: <token>` | `{ userId, event, data, ttl? }` | `{ success, delivered?, online?, reached?, error? }` |
|
||||
| POST | `/internal/broadcast` | `X-Internal-Key: <token>` | `{ event, data, filter? }` | `{ success, reached? }` |
|
||||
| GET | `/internal/online/<userID>` | `X-Internal-Key: <token>` | — | `{ online: bool, instances: [] }` |
|
||||
|
||||
**向后兼容**:
|
||||
|
||||
- 鉴权头同时接受 `X-Internal-Token`(v1 legacy)
|
||||
- `/internal/push` 请求体同时接受 `user_id`(snake_case,v1 legacy)
|
||||
|
||||
### 9.3 Kafka 消费
|
||||
|
||||
| Topic | 消息格式 | 来源 |
|
||||
| ---------------------------------- | ---------------------------- | --------------------- |
|
||||
| `edu.notify.notification.sent` | `NotificationRequested` JSON | msg Outbox publisher |
|
||||
| `edu.notify.notification.sent.dlq` | 原始消息(失败 3 次后投递) | push-gateway 自动派生 |
|
||||
|
||||
**消息字段**:`event_id` / `user_id` / `event_type` / `channel` / `title` / `content` / `data` / `broadcast` / `occurred_at`
|
||||
|
||||
**event_type 透传**:push-gateway 从 Kafka 消息的 `event_type` 字段读取事件类型,作为 WebSocket 消息的 `event` 字段透传,不硬编码事件类型。
|
||||

|
||||
## 10. 后续工作(v3 展望)
|
||||
|
||||
| 工作项 | 优先级 | 说明 |
|
||||
| ------------------- | ------ | ------------------------------------------------------------------------ |
|
||||
| P6 Reconnect 协议 | P1 | `session_id` + `last_seq` + ring buffer(100 条/用户)支持断线重连后补发 |
|
||||
| P6 离线消息推送 | P2 | 与 msg 服务集成,离线用户消息落库后通过 SMS/邮件/应用内通知补发 |
|
