## §1 我提供什么(对外接口)
|
||
|
||
### 1.1 gRPC 接口(如有)
|
||
|
||
| Service | RPC | 请求 | 响应 | 端口 |
|
||
| --------------------- | ------------------ | ------------------------- | -------------------------- | ----- |
|
||
| TextbookService | CreateTextbook | CreateTextbookRequest | Textbook | 50054 |
|
||
| TextbookService | GetTextbook | GetTextbookRequest | Textbook | 50054 |
|
||
| TextbookService | ListTextbooks | ListTextbooksRequest | ListTextbooksResponse | 50054 |
|
||
| ChapterService | GetChapter | GetChapterRequest | Chapter | 50054 |
|
||
| ChapterService | ListChapters | ListChaptersRequest | ListChaptersResponse | 50054 |
|
||
| ChapterService | CreateChapter | CreateChapterRequest | Chapter | 50054 |
|
||
| ChapterService | UpdateChapter | UpdateChapterRequest | Chapter | 50054 |
|
||
| KnowledgeGraphService | GetPrerequisites | GetPrerequisitesRequest | KnowledgePointsResponse | 50054 |
|
||
| KnowledgeGraphService | GetLearningPath | GetLearningPathRequest | LearningPath | 50054 |
|
||
| KnowledgeGraphService | AddPrerequisite | AddPrerequisiteRequest | AddPrerequisiteResponse | 50054 |
|
||
| KnowledgeGraphService | RemovePrerequisite | RemovePrerequisiteRequest | RemovePrerequisiteResponse | 50054 |
|
||
| QuestionService | CreateQuestion | CreateQuestionRequest | Question | 50054 |
|
||
| QuestionService | GetQuestion | GetQuestionRequest | Question | 50054 |
|
||
| QuestionService | ListQuestions | ListQuestionsRequest | ListQuestionsResponse | 50054 |
|
||
| QuestionService | UpdateQuestion | UpdateQuestionRequest | Question | 50054 |
|
||
| QuestionService | DeleteQuestion | DeleteQuestionRequest | DeleteQuestionResponse | 50054 |
|
||
| QuestionService | PublishQuestion | PublishQuestionRequest | PublishQuestionResponse | 50054 |
|
||
| QuestionService | SearchQuestions | SearchQuestionsRequest | SearchQuestionsResponse | 50054 |
|
||
|
||
### 1.2 HTTP 端点(如有)
|
||
|
||
无对外 HTTP 端点,仅 gRPC。
|
||
|
||
### 1.3 GraphQL schema(如 BFF)
|
||
|
||
不适用。
|
||
|
||
### 1.4 Kafka 事件发布(如有)
|
||
|
||
| Topic | Event | 消费方 |
|
||
| ---------------------------------- | -------------------------------------------------------------------------------------- | -------------------------------------------------- |
|
||
| edu.content.knowledge_point.events | KnowledgePointEvent(action: created/updated/prerequisite_added/prerequisite_removed) | data-ana / ai / Neo4j Sync Worker / ES Sync Worker |
|
||
| edu.content.question.events | QuestionEvent(action: created/updated/published/deleted) | data-ana |
|
||
|
||
### 1.5 错误码前缀
|
||
|
||
`CONTENT_`(如 CONTENT_TEXTBOOK_NOT_FOUND、CONTENT_QUESTION_DUPLICATE)
|
||
|
||
---
|
||
|
||
## §2 我消费什么(依赖上游)
|
||
|
||
### 2.1 gRPC 调用(同步)
|
||
|
||
无直接 gRPC 调用上游。content 通过 Kafka 事件接收 core-edu 班级/学生变更用于数据一致性。
|
||
|
||
### 2.2 Kafka 事件订阅(异步)
|
||
|
||
| Topic | Event | 发布方 | mock 策略 |
|
||
| ---------------- | --------------------------------- | --------------- | ----------------------------------------------------- |
|
||
| edu.class.events | ClassEvent(action: transferred) | core-edu (ai08) | core-edu 就绪前不订阅,content 内部不依赖班级实时数据 |
|
||
| edu.exam.events | ExamEvent | core-edu (ai08) | core-edu 就绪前忽略,题目关联知识点不依赖考试事件 |
|
||
|
||
### 2.3 HTTP 调用(如有)
|
||
|
||
无。
|
||
|
||
---
|
||
|
||
## §3 就绪信号
|
||
|
||
### 3.1 我依赖的上游就绪标志
|
||
|
||
- [ ] core-edu gRPC 50053 启用(ai08)—— 用于知识点与班级关联(可选,content 可先独立运行)
|
||
- [ ] edu.class.events / edu.exam.events topic 有事件发布(ai08)
|
||
|
||
### 3.2 我的就绪标志(供下游消费)
|
||
|
||
- [ ] content gRPC 50054 启用(HealthService.Check 返回 SERVING)
|
||
- [ ] TextbookService 3 RPC 可调用
|
||
- [ ] ChapterService 4 RPC 可调用
|
||
- [ ] KnowledgeGraphService 4 RPC 可调用(GetPrerequisites/GetLearningPath/AddPrerequisite/RemovePrerequisite)
|
||
- [ ] QuestionService 7 RPC 可调用(含 SearchQuestions 全文检索)
|
||
- [ ] edu.content.knowledge_point.events / edu.content.question.events topic 可发布
|
||
|

|
||
|
||
## §4 Mock 策略
|
||
|
||
### 4.1 我提供的 mock
|
||
|
||
在 content 真实服务就绪前,为下游(teacher-bff / student-bff / ai / data-ana)提供以下 mock:
|
||
|
||
- **gRPC mock**:使用 grpc-mock 拦截 50054 端口
|
||
- TextbookService.ListTextbooks 返回固定 5 个 Textbook(语数英理化)
|
||
- ChapterService.ListChapters 返回固定章节树(每教材 10 章)
|
||
- KnowledgeGraphService.GetLearningPath 返回固定 8 个 KnowledgePoint 推荐顺序
|
||
- KnowledgeGraphService.GetPrerequisites 返回固定 3 个前置知识点
|
||
- QuestionService.SearchQuestions 返回固定 20 个 Question(含 options)
|
||
- **Kafka mock**:content 就绪前不发布真实事件,下游使用本地 stub
|
||
|
||
### 4.2 我消费的 mock
|
||
|
||
在真实 core-edu 就绪前,content 使用以下 mock:
|
||
|
||
- 班级/学生数据:不依赖 core-edu 实时数据,知识点关联使用固定 subject_id/grade
|
||
- 事件订阅:不订阅 edu.class.events / edu.exam.events,内部数据自洽
