# 知习后端待完成事项清单
|
||
|
||
> 按业务开发顺序排列。**2026-05-16 更新:AI 基础设施完成,12 个 Repository 全部迁到 Prisma。**
|
||
|
||
---
|
||
|
||
## 1. 登录 / 认证模块 Auth
|
||
|
||
这是第一优先级。因为后面所有数据都要绑定 `userId`。
|
||
|
||
### 要做的接口
|
||
|
||
```text
|
||
POST /api/auth/dev-login
|
||
POST /api/auth/apple
|
||
POST /api/auth/refresh
|
||
POST /api/auth/logout
|
||
GET /api/users/me
|
||
PATCH /api/users/me
|
||
```
|
||
|
||
### 第一阶段先做
|
||
|
||
```text
|
||
POST /api/auth/dev-login
|
||
POST /api/auth/refresh
|
||
GET /api/users/me
|
||
```
|
||
|
||
Apple 登录可以随后接入,但后端结构要先预留。
|
||
|
||
### 需要的表
|
||
|
||
```text
|
||
users
|
||
auth_accounts
|
||
refresh_tokens
|
||
```
|
||
|
||
### 核心逻辑
|
||
|
||
```text
|
||
dev-login 创建 / 查找用户
|
||
生成 accessToken
|
||
生成 refreshToken
|
||
refreshToken hash 入库
|
||
/users/me 返回当前用户
|
||
refresh 接口刷新 token
|
||
logout 撤销 refreshToken
|
||
```
|
||
|
||
### Apple 登录需要什么
|
||
|
||
后端不需要 iOS 证书,只需要:
|
||
|
||
```text
|
||
APPLE_BUNDLE_ID=cloud.longde.AIStudyApp
|
||
APPLE_ISSUER=https://appleid.apple.com
|
||
APPLE_JWKS_URL=https://appleid.apple.com/auth/keys
|
||
```
|
||
|
||
Apple 登录接口核心参数:
|
||
|
||
```json
|
||
{
|
||
"identityToken": "eyJ..."
|
||
}
|
||
```
|
||
|
||
可选参数:
|
||
|
||
```json
|
||
{
|
||
"authorizationCode": "...",
|
||
"userIdentifier": "...",
|
||
"email": "...",
|
||
"fullName": {
|
||
"givenName": "...",
|
||
"familyName": "..."
|
||
}
|
||
}
|
||
```
|
||
|
||
---
|
||
|
||
## 2. 权限系统 Permission
|
||
|
||
登录后马上要做最小权限。
|
||
|
||
### 第一版权限规则
|
||
|
||
```text
|
||
普通用户只能访问自己的资源
|
||
所有用户资源必须校验 userId
|
||
普通用户不能访问 /api/admin/*
|
||
知识库默认 PRIVATE
|
||
创建知识库的人就是 owner
|
||
```
|
||
|
||
### 平台角色
|
||
|
||
```text
|
||
USER
|
||
ADMIN
|
||
SUPER_ADMIN
|
||
```
|
||
|
||
### 后期资源角色
|
||
|
||
```text
|
||
OWNER
|
||
EDITOR
|
||
VIEWER
|
||
```
|
||
|
||
第一版可以先不做协作者,只做:
|
||
|
||
```text
|
||
knowledgeBase.userId === currentUser.id
|
||
```
|
||
|
||
---
|
||
|
||
## 3. 用户模块 Users
|
||
|
||
### 接口
|
||
|
||
```text
|
||
GET /api/users/me
|
||

||
```

|
||
```text
|
||

||
role
|
||
status
|
||

|
||
createdAt
|
||
updatedAt
|
||
```
|
||
|
||

|
||
|
||
```text
|
||
App 启动恢复登录态

|
||
|
||
## 13. Repository 迁移 Map → Prisma ✅ 全部完成
|
||
|
||
> **2026-05-16**:12 个业务 repository 全部从 `Map<string, T>` / `Array<T>` 迁到 Prisma。
|
||
|
||
| 批次 | 模块 | Repository | 备注 |
|
||
|------|------|-----------|------|
|
||
| 第 1 批 | KnowledgeBase / KnowledgeItems | ✅ Prisma | 核心知识体系 |
|
||
| 第 2 批 | ActiveRecall / LearningSession / AiAnalysis / FocusItems | ✅ Prisma | 学习闭环主干 |
|
||
| 第 3 批 | Review / LearningActivity | ✅ Prisma | 复习和统计 |
|
||
| 第 4 批 | DocumentImport / Notifications / Waitlist / Feedback | ✅ Prisma | 辅助模块 |
|
||
|
||
### 改动范围
|
||
|
||
```text
|
||
12 个 repository 重写(注入 PrismaService、删除 Map/Array、删除 generateShortId)
|
||
5 个 service 微调(方法加 userId 参数)
|
||
4 个 controller 加 @CurrentUser()(FocusItems / Review / LearningActivity / Notifications)
|
||
1 个 Prisma schema 新增模型(WaitlistEntry)
|
||
```
|
||
|
||
### 统一变更
|
||
|
||
```text
|
||
- 删除所有 generateShortId() 调用,改用 Prisma @default(cuid())
|
||
- 删除所有 OnModuleInit 种子假数据
|
||
- 所有查询方法加 userId 过滤
|
||
- 复杂字段(数组/对象)存 Prisma Json 字段
|
||
```
|
||
|
||

||
|
||
```text
|
||

|
||
会员额度
|
||
后台成本看板
|
||
模型切换

```text
|
||
✅ 1. 建 users / auth_accounts / refresh_tokens 表
|

|
||
✅ 4. 做 POST /api/auth/refresh
|
||
✅ 5. 做 JwtAuthGuard
|
||
✅ 6. 做 CurrentUser 装饰器
|
||
✅ 7. 做 GET /api/users/me
|
||
✅ 8. 12 个 Repository Map → Prisma
|
||
✅ 9. AI 三层架构落地(Provider → Gateway → Workflow)
|
||
✅ 10. 接 POST /api/auth/apple
|
||
