+## 1. 概述 (Overview)
+
+本接口文档描述了系统的后端API接口，主要包含 CRM（小程序业务）模块和 System（系统管理）模块。

+
+## 2. 通用响应格式 (Common Response Format)
+
+接口通常返回 JSON 格式数据，结构如下：

+# 前端接口文档 (Frontend API Documentation)
+
+本文档说明如何在前端项目（微信小程序和Web管理后台）中使用接口。
+
+## 1. 微信小程序 (WeChat Mini Program)
+
+小程序目录：`wechat-mini-program/`
+
+### 1.1 请求工具 (Request Utility)
+
+封装文件：`utils/request.js`
+
+该工具自动处理了：
+- Base URL 拼接
+- Token 注入 (Bearer Token)
+- 响应拦截与错误处理
+- 响应数据解包 (Unwrapping `data` field)
+
+### 1.2 使用方法 (Usage)
+
+在页面或组件中引入 `request` 方法：
+
+```javascript
+const { request } = require('../../utils/request')
+// 或者在某些地方通过 app 获取 (如果挂载了)
+// const app = getApp() 
+```
+
+**示例代码：**
+
+```javascript
+// GET 请求
+request({
+  url: '/projects/',
+  method: 'GET',
+  data: { page: 1, page_size: 10 }
+}).then(res => {
+  console.log('项目列表:', res.results)
+}).catch(err => {
+  console.error('获取失败:', err)
+})
+
+// POST 请求
+request({
+  url: '/student-projects/',
+  method: 'POST',
+  data: {
+    project: 1,
+    status: 'enrolled'
+  }
+}).then(res => {
+  wx.showToast({ title: '报名成功' })
+})
+```
+
+### 1.3 常用接口封装
+
+虽然可以直接使用 `request`，但建议在 `api/` 目录下（如果存在）或各页面 JS 中进行简单封装。
+
+目前主要直接在 `pages/` 对应的 `.js` 文件中调用。例如 `pages/index/index.js` 调用 `/banners/` 和 `/projects/`。
+
+---
+
+## 2. Web 管理后台 (Admin Client)
+
+Web 端目录：`admin/client/`
+技术栈：Vue.js + Element UI
+
+### 2.1 接口目录结构
+
+所有 API 请求定义在 `src/api/` 目录下，按模块划分：
+
+- `src/api/crm.js`: 核心业务接口（项目、学员、教师等）
+- `src/api/system/user.js`: 系统用户接口
+- `src/api/login.js`: 登录相关接口
+
+### 2.2 定义接口 (Defining APIs)
+
+以 `src/api/crm.js` 为例：
+
+```javascript
+import request from '@/utils/request'
+
+// 获取教师列表
+export function getTeachers(query) {
+  return request({
+    url: '/teachers/',
+    method: 'get',
+    params: query
+  })
+}
+
+// 创建教师
+export function createTeacher(data) {
+  return request({
+    url: '/teachers/',
+    method: 'post',
+    data
+  })
+}
+```
+
+### 2.3 在组件中使用 (Usage in Components)
+
+在 Vue 组件中引入并调用：
+
+```vue
+<script>
+import { getTeachers, createTeacher } from '@/api/crm'
+
+export default {
+  data() {
+    return {
+      list: [],
+      query: { page: 1, limit: 20 }
+    }
+  },
+  created() {
+    this.fetchData()
+  },
+  methods: {
+    fetchData() {
+      getTeachers(this.query).then(response => {
+        this.list = response.data.results
+        // 注意：根据后端响应拦截器的配置，response 可能已经是 data 部分，
+        // 或者需要访问 response.data。请参考 src/utils/request.js
+      })
+    },
+    handleAdd() {
+      createTeacher(this.form).then(() => {
+        this.$message.success('创建成功')
+        this.fetchData()
+      })
+    }
+  }
+}
+</script>
+```
+
+### 2.4 请求拦截器 (Interceptors)
+
+位置：`src/utils/request.js`
+
+- **Request Interceptor**: 自动添加 `Authorization: Bearer <token>`
+- **Response Interceptor**: 
+  - 统一处理非 200 状态码
+  - 统一处理业务错误码
+  - 登录过期自动登出
+
+## 3. 注意事项 (Notes)
+
+1. **Base URL 配置**:
+   - 小程序：`wechat-mini-program/config/env.js` (或 `app.js`)
+   - Web 后台：`.env.development` 和 `.env.production` 中的 `VUE_APP_BASE_API`
+
+2. **分页 (Pagination)**:
+   - 默认参数：`page` (页码), `limit` 或 `size` (每页数量)
+   - 响应格式：`{ count: Total, results: [Array] }`

+
+## 🚀 快速开始
+
+### 1. 启动后端服务 (Django)
+
+1.  进入 `admin/server` 目录。
+2.  建议使用项目自带的虚拟环境（如果存在）或创建新的虚拟环境。
+    *   **使用自带环境 (Windows)**:
+        ```powershell
+        .\admin\server\.venv\Scripts\python.exe admin/server/manage.py runserver 0.0.0.0:8000
+        ```
+    *   **手动配置环境**:
+        ```bash
+        cd admin/server
+        # 创建并激活虚拟环境
+        python -m venv venv
+        # Windows 激活
+        .\venv\Scripts\activate
+        # 安装依赖
+        pip install -r requirements.txt
+        # 迁移数据库
+        python manage.py migrate
+        # 启动服务
+        python manage.py runserver 0.0.0.0:8000
+        ```
+3.  访问 `http://localhost:8000/` 确认服务运行正常。
+
+### 2. 启动管理后台 (Vue.js)
+
+1.  进入前端目录：
+    ```bash
+    cd admin/client
+    ```
+2.  安装依赖：
+    ```bash
+    npm install
+    # 如果遇到依赖冲突，尝试使用:
+    # npm install --legacy-peer-deps
+    ```
+3.  启动开发服务器：
+    *   **Windows (PowerShell)**:
+        ```powershell
+        # 如果 Node 版本 >= 17，需要设置 NODE_OPTIONS
+        $env:NODE_OPTIONS="--openssl-legacy-provider"
+        npm run dev
+        ```
+    *   **Linux / macOS**:
+        ```bash
+        # 如果 Node 版本 >= 17
+        export NODE_OPTIONS=--openssl-legacy-provider
+        npm run dev
+        ```
+    *   **通用**:
+        ```bash
+        npm run dev
+        ```
+4.  启动完成后，浏览器会自动打开 `http://localhost:9528`。
+
+### 3. 启动微信小程序
+
+1.  下载并安装 [微信开发者工具](https://developers.weixin.qq.com/miniprogram/dev/devtools/download.html)。
+2.  打开工具，选择“导入项目”。
+3.  选择项目根目录下的 `wechat-mini-program` 文件夹。
+4.  设置 AppID（或使用测试号），编译并预览。
