+# 小程序用户认证Starter
+
+这是一个基于Taro的小程序用户认证starter项目，集成了完整的用户登录、注册功能，并连接到后端API。
+
+## 功能特性
+
+- ✅ 用户注册和登录
+- ✅ JWT Token认证
+- ✅ 用户信息管理
+- ✅ 响应式设计
+- ✅ 错误处理
+- ✅ 本地存储
+
+## 技术栈
+
+- **框架**: Taro 4.1.4
+- **语言**: TypeScript
+- **样式**: CSS
+- **HTTP请求**: Taro.request
+- **状态管理**: 本地存储
+
+## 项目结构

+├── .env.development        # 开发环境变量
+├── .env.production         # 生产环境变量
+└── package.json
+```
+
+## 快速开始
+
+### 1. 安装依赖
+
+```bash
+cd mini
+pnpm install
+```
+
+### 2. 配置环境变量
+
+编辑 `.env.development` 和 `.env.production` 文件，设置API地址：
+
+```bash
+API_BASE_URL=http://localhost:3000
+API_VERSION=v1
+```
+
+### 3. 启动开发服务器
+
+```bash
+# 微信小程序
+npm run dev:weapp
+
+# H5
+npm run dev:h5
+```
+
+### 4. 构建生产版本
+
+```bash
+# 微信小程序
+npm run build:weapp
+
+# H5
+npm run build:h5
+```
+
+## API接口
+
+### 认证相关
+- POST `/api/v1/auth/login/password` - 密码登录
+- POST `/api/v1/auth/register` - 用户注册
+- GET `/api/v1/auth/me` - 获取当前用户信息
+- POST `/api/v1/auth/logout` - 退出登录
+
+### 用户相关
+- GET `/api/v1/users` - 获取用户列表
+- GET `/api/v1/users/:id` - 获取单个用户
+- PUT `/api/v1/users/:id` - 更新用户信息
+- DELETE `/api/v1/users/:id` - 删除用户
+
+## 使用说明
+
+### 认证状态管理
+
+项目提供了完整的认证状态管理工具：
+
+```typescript
+import { authManager } from '@/utils/auth'
+
+// 检查登录状态
+const isLoggedIn = authManager.isLoggedIn()
+
+// 获取用户信息
+const user = authManager.getUserInfo()
+
+// 获取token
+const token = authManager.getToken()
+
+// 登录
+const user = await authManager.login('username', 'password')
+
+// 注册
+const user = await authManager.register({
+  username: 'newuser',
+  password: 'password123',
+  email: 'user@example.com'
+})
+
+// 退出
+await authManager.logout()
+```
+
+### API调用
+
+使用封装的API客户端进行网络请求：
+
+```typescript
+import { authApi, userApi } from '@/utils/api'
+
+// 登录
+const response = await authApi.login({
+  username: 'username',
+  password: 'password'
+})
+
+// 获取用户列表
+const users = await userApi.getUsers()
+
+// 更新用户信息
+const updated = await userApi.updateUser(1, { username: 'newname' })
+```
+
+## 环境配置
+
+### 开发环境
+- API地址: `http://localhost:3000`
+- 环境变量文件: `.env.development`
+
+### 生产环境
+- API地址: `https://your-domain.com`
+- 环境变量文件: `.env.production`
+
+## 注意事项
+
+1. **CORS配置**: 确保后端API已配置CORS，允许小程序域名访问
+2. **HTTPS**: 生产环境必须使用HTTPS
+3. **域名配置**: 微信小程序需要在后台配置request合法域名
+4. **存储限制**: 小程序本地存储有大小限制，避免存储过多数据
+
+## 常见问题
+
+### 1. 网络请求失败
+- 检查API地址配置是否正确
+- 确保后端服务已启动
+- 检查网络连接
+
+### 2. 跨域问题
+- 在后端配置CORS
+- 使用代理服务器（开发环境）
+
+### 3. 登录状态丢失
+- 检查token是否正确存储
+- 确认token有效期
+
+## 扩展建议
+
+1. **添加微信登录**: 集成微信OAuth
+2. **手机号登录**: 添加短信验证码功能
+3. **第三方登录**: 支持QQ、微博等
+4. **用户头像**: 添加头像上传功能
+5. **用户权限**: 实现角色权限管理
