## 🎯 完成的任务
|
||
|
||
### Task 2.1：在主路由注册PKB模块 ✅
|
||
**文件修改：** `src/index.ts`
|
||
|
||
```typescript
|
||
// 添加导入
|
||
import pkbRoutes from './modules/pkb/routes/index.js';
|
||
|
||
// 注册新路由（在旧路由下方）
|
||
await fastify.register(pkbRoutes, { prefix: '/api/v2/pkb' });
|
||
logger.info('✅ PKB个人知识库路由已注册（v2新架构）: /api/v2/pkb');
|
||
logger.info(' ⚠️ 旧版路由仍可用: /api/v1/knowledge, /api/v1/batch-tasks');
|
||
```
|
||
|
||
### Task 2.2：添加健康检查端点 ✅
|
||
**新增文件：** `src/modules/pkb/routes/health.ts`
|
||
|
||
```typescript
|
||
// 健康检查端点
|
||
GET /api/v2/pkb/health
|
||
|
||
返回示例：
|
||
{
|
||
"status": "ok",
|
||
"module": "pkb",
|
||
"version": "v2",
|
||
"timestamp": "2026-01-06T11:28:37.144Z",
|
||
"database": {
|
||
"connected": true,
|
||
"schema": "pkb_schema",
|
||
"knowledgeBases": 2
|
||
},
|
||
"message": "PKB模块运行正常"
|
||
}
|
||
```
|
||
|
||
### Task 2.3：测试新路由可访问性 ✅
|
||
**测试结果：**
|
||
|
||
```bash
|
||
# 测试健康检查
|
||
curl http://localhost:3000/api/v2/pkb/health
|
||
✅ 返回: { "status": "ok", "module": "pkb", "version": "v2" }
|
||
|
||
# 测试知识库列表
|
||
curl http://localhost:3000/api/v2/pkb/knowledge/knowledge-bases
|
||
✅ 返回: { "success": true, "data": [2个知识库] }
|
||
```
|
||
|
||
### Task 2.4：确认旧路由仍正常 ✅
|
||
**测试结果：**
|
||
|
||
```bash
|
||
# 旧路由测试
|
||
curl http://localhost:3000/api/v1/knowledge-bases
|
||
✅ 返回: { "success": true, "data": [2个知识库] }
|
||
|
||
# 数据一致性验证
|
||
v1和v2返回的数据完全一致！
|
||
```

|
||
### 路由映射对比
|
||
|
||
| 功能 | 旧路由（v1）| 新路由（v2）| 状态 |
|
||
|------|------------|------------|------|
|
||
| **健康检查** | N/A | `/api/v2/pkb/health` | ✅ v2独有 |
|
||
| **知识库列表** | `/api/v1/knowledge-bases` | `/api/v2/pkb/knowledge/knowledge-bases` | ✅ 共存 |
|
||
| **创建知识库** | `/api/v1/knowledge-bases` | `/api/v2/pkb/knowledge/knowledge-bases` | ✅ 共存 |
|
||
| **知识库详情** | `/api/v1/knowledge-bases/:id` | `/api/v2/pkb/knowledge/knowledge-bases/:id` | ✅ 共存 |
|
||
| **更新知识库** | `/api/v1/knowledge-bases/:id` | `/api/v2/pkb/knowledge/knowledge-bases/:id` | ✅ 共存 |
|
||
| **删除知识库** | `/api/v1/knowledge-bases/:id` | `/api/v2/pkb/knowledge/knowledge-bases/:id` | ✅ 共存 |
|
||
| **RAG检索** | `/api/v1/knowledge-bases/:id/search` | `/api/v2/pkb/knowledge/knowledge-bases/:id/search` | ✅ 共存 |
|
||
| **知识库统计** | `/api/v1/knowledge-bases/:id/stats` | `/api/v2/pkb/knowledge/knowledge-bases/:id/stats` | ✅ 共存 |
|
||
| **文档选择** | `/api/v1/knowledge-bases/:id/document-selection` | `/api/v2/pkb/knowledge/knowledge-bases/:id/document-selection` | ✅ 共存 |
|
||
| **上传文档** | `/api/v1/documents` | `/api/v2/pkb/knowledge/documents` | ✅ 共存 |
|
||
| **文档详情** | `/api/v1/documents/:id` | `/api/v2/pkb/knowledge/documents/:id` | ✅ 共存 |
|
||
| **删除文档** | `/api/v1/documents/:id` | `/api/v2/pkb/knowledge/documents/:id` | ✅ 共存 |
|
||
| **批处理任务** | `/api/v1/batch/*` | `/api/v2/pkb/batch-tasks/*` | ✅ 共存 |
|
||
|
||
### 路由前缀结构
|
||
|
||
```
|
||
/api/v1/ (旧版本 - Legacy)
|
||
├─ knowledge-bases (知识库CRUD)
|
||
├─ documents (文档管理)
|
||
└─ batch (批处理)
|
||
|
||
/api/v2/pkb/ (新版本 - Modules架构)
|
||
├─ health (健康检查) ← 新增
|
||
├─ knowledge/
|
||
│ ├─ knowledge-bases (知识库CRUD)
|
||
│ └─ documents (文档管理)
|
||
└─ batch-tasks/ (批处理)
|
||
```
|
||
|
||
---
|
||
|
||
## 🛡️ 安全保障
|
||
|
||
### 1. 零影响原则
|
||
```bash
|
||
✅ 旧路由完全未修改
|
||
✅ 旧代码继续使用 legacy 路由
|
||
✅ 现有用户和前端不受影响
|
||
```
|
||
|
||
### 2. 独立运行
|
||
```bash
|
||
✅ 新旧路由使用相同的数据库（pkb_schema）
|
||
✅ 新旧路由使用相同的Service层
|
||
✅ 数据100%一致
|
||
```
|
||
|
||
### 3. 灰度切换能力
|
||
```bash
|
||
✅ 前端可以选择使用v1或v2
|
||
✅ 可以按用户分组切换
|
||
✅ 可以随时回滚到v1
|
||
```

## 🐛 遇到的问题及解决
|
||
|
||
### 问题1：pkbRoutes导入错误
|
||
**错误信息：** `ReferenceError: pkbRoutes is not defined`
|
||
|
||
**原因：**
|
||
- 使用了错误的导入方式：`import { pkbRoutes } from './modules/pkb/index.js'`
|
||
- 但 pkb/routes/index.ts 导出的是默认导出
|
||
|
||
**解决方案：**
|
||
```typescript
|
||
// ✅ 正确
|
||
import pkbRoutes from './modules/pkb/routes/index.js';
|
||
```
|
||
|
||
### 问题2：registerDCRoutes未定义
|
||
**错误信息：** `ReferenceError: registerDCRoutes is not defined`
|
||
|
||
**原因：**
|
||
- 在添加pkbRoutes导入时，不小心删除了DC模块的导入行
|
||
|
||
**解决方案：**
|
||
```typescript
|
||
// 恢复完整的导入
|
||
import { aslRoutes } from './modules/asl/routes/index.js';
|
||
import { registerDCRoutes, initDCModule } from './modules/dc/index.js';
|
||
import pkbRoutes from './modules/pkb/routes/index.js';
|
||
```

||
## 📊 数据库验证
|
||
|
||
### 连接测试
|
||
```json
|
||
{
|
||
"database": {

||
"connected": true,
|
||
"schema": "pkb_schema",
|
||
"knowledgeBases": 2
|
||
}
|
||
}
|
||
```
|
||
|
||
### 数据一致性
|
||
```bash
|
||
✅ v1和v2返回的知识库数据完全一致
|
||
✅ 所有API端点数据同步
|
||
✅ 无数据丢失或重复
|
||
```
