|
||
## 🔧 修复的问题
|
||
|
||
### 问题 1：健康检查路由冲突
|
||
|
||
**错误：**
|
||
```
|
||
FastifyError [Error]: Method 'GET' already declared for route '/health'
|
||
```
|
||
|
||
**原因：** `/health` 路由在两个地方注册（`index.ts` 和 `healthCheck.ts`）
|
||
|
||
**解决：** 移除 `index.ts` 中的重复路由，统一在 `registerHealthRoutes()` 中注册
|
||
|
||
**文件：**
|
||
- `backend/src/index.ts` ✅
|
||
- `backend/src/common/health/healthCheck.ts` ✅
|
||
|
||
---
|
||
|
||
### 问题 2：TypeScript 接口导出错误
|
||
|
||
**错误：**
|
||
```
|
||
SyntaxError: The requested module './StorageAdapter.js' does not provide an export named 'StorageAdapter'
|
||
```
|
||
|
||
**原因：** TypeScript 接口在运行时不存在，不能使用普通的 `export { }` 导出
|
||
|
||
**解决：** 使用 `export type { }` 导出接口类型
|
||
|
||
**修改文件：**
|
||
```typescript
|
||
// 修改前
|
||
export { StorageAdapter } from './StorageAdapter.js'
|
||
|
||
// 修改后
|
||
export type { StorageAdapter } from './StorageAdapter.js'
|
||
```
|
||
|
||
**影响文件：**
|
||
- `backend/src/common/storage/index.ts` ✅
|
||
|
||
---
|
||
|
||
### 问题 3：Winston 依赖缺失
|
||
|
||
**错误：** 找不到模块 `winston`
|
||
|
||
**解决：** 安装依赖
|
||
```bash
|
||
npm install winston
|
||
# @types/winston 不需要安装（winston自带类型定义）
|
||
```

|
||
2. **日志系统** - Winston 配置完成，支持结构化日志
|
||
3. **缓存服务** - MemoryCacheAdapter 完整实现
|
||
4. **异步任务** - MemoryQueue 完整实现

|
||
|
||
### 🚀 可以开始 ASL 模块开发
|
||
|
||
**平台基础设施已就绪，所有功能验证通过！**
|
||
|
||
业务模块开发时可以直接使用：
|
||
|
||
```typescript
|
||
import { storage } from '@/common/storage'
|
||
import { logger } from '@/common/logging'
|
||
import { cache } from '@/common/cache'
|
||
import { jobQueue } from '@/common/jobs'
|
||
```
|
||
|
||
**零代码环境切换：** 只需修改环境变量，无需改动业务代码！
|
||
|
||
---
|
||
|
||
## 📝 后续工作
|
||
|
||
### 当前可以做的（本地环境）✅
|
||
|
||
- ✅ 开发 ASL 模块（使用 LocalAdapter）
|
||
- ✅ 开发其他业务模块
|
||
- ✅ 本地测试和验证
|
||
|
||
### 云端部署前需要做的 🔄
|
||
|
||
1. **安装云服务依赖**
|
||
```bash
|
||
npm install ali-oss # 阿里云OSS
|
||
npm install ioredis # Redis
|
||
```
|
||
|
||
2. **取消注释云端实现**
|
||
- `OSSAdapter.ts` - 实现OSS上传下载
|
||
- `RedisCacheAdapter.ts` - 实现Redis缓存
|
||
- `DatabaseQueue.ts` - 实现数据库任务队列（可选）
|
||
|
||
3. **配置生产环境变量**
|
||
```bash
|
||
STORAGE_TYPE=oss
|
||
CACHE_TYPE=redis
|
||
QUEUE_TYPE=database
|
||
```
|
||
|
||
4. **部署测试**
|
||
- SAE 环境部署
|
||
- 连接池测试
|
||
- 健康检查验证
|
||
- 性能测试
