+# API 模块使用说明
+
+## 概述
+
+本项目使用统一的API请求工具 `@/utils/request.js`，所有API请求都通过该工具进行，无需重复配置基地址和请求头。
+
+## 目录结构
+
+```
+api/
+├── index.js          # API模块统一导出
+├── lease/            # 租赁相关API
+│   └── lease.js
+├── device/           # 设备相关API
+│   └── device.js
+├── banner/           # 轮播图相关API
+│   └── banner.js
+├── article/          # 文章相关API
+│   └── article.js
+└── auth/             # 认证相关API
+    └── auth.js
+```
+
+## 使用方法
+
+### 1. 导入API方法
+
+```javascript
+// 方式1：从具体模块导入
+import { getDeviceTypes, getPeriodPackages } from '@/api/lease/lease.js'
+
+// 方式2：从统一入口导入
+import { getDeviceTypes, getPeriodPackages } from '@/api/index.js'
+```
+
+### 2. 在组件中使用
+
+```javascript
+export default {
+  methods: {
+    async fetchData() {
+      try {
+        const response = await getDeviceTypes()
+        
+        if (response.code === 200) {
+          this.deviceTypes = response.data
+        } else {
+          throw new Error(response.message || '请求失败')
+        }
+      } catch (error) {
+        console.error('获取数据失败:', error)
+        uni.showToast({
+          title: error.message || '获取数据失败',
+          icon: 'error',
+        })
+      }
+    }
+  }
+}
+```
+
+## API方法命名规范
+
+- 获取列表：`getXxxList`
+- 获取详情：`getXxxDetail`
+- 创建：`createXxx`
+- 更新：`updateXxx`
+- 删除：`deleteXxx`
+
+## 请求工具特性
+
+### 自动处理
+- ✅ 基地址配置
+- ✅ 请求头设置
+- ✅ Token管理
+- ✅ Loading状态
+- ✅ 错误处理
+- ✅ 超时处理
+
+### 配置选项
+```javascript
+request({
+  url: '/api/endpoint',
+  method: 'GET',
+  params: { id: 1 },
+  loadingText: '加载中...',    // 自定义loading文本
+  showLoading: true,          // 是否显示loading
+  timeout: 60000,            // 超时时间
+  noToken: false,            // 是否需要token
+})
+```
+
+## 环境配置
+
+请求工具会根据当前环境自动选择对应的配置：
+
+- **开发环境**：`http://192.168.2.114:4601`
+- **体验版**：`http://192.168.2.114:4601`
+- **正式版**：`http://192.168.2.114:4601`
+
+## 错误处理
+
+所有API请求都会自动处理以下错误：
+
+- 401：登录过期，自动跳转登录页
+- 403：权限不足
+- 404：资源不存在
+- 500：服务器错误
+- 网络错误：超时、连接失败等
+
+## 注意事项
+
+1. **方法名冲突**：避免页面方法名与API方法名相同，建议使用别名导入
+2. **Loading管理**：请求工具已内置loading管理，无需手动处理
+3. **错误提示**：统一使用 `uni.showToast` 显示错误信息
+4. **Token处理**：开发环境支持临时token，生产环境使用真实token
