+# Market Uniapp - 登录功能修复
+
+## 问题描述
+原代码无法模拟登录过程，登录按钮点击后没有正确的响应和页面跳转。
+
+## 修复内容
+
+### 1. 创建了LoginService类 (src/api/login.js)
+- 遵循OOP原则，创建了完整的登录服务类
+- 提供了模拟登录API调用
+- 实现了登录状态管理
+- 包含用户信息存储和获取功能
+- 提供了登出功能
+
+### 2. 更新了登录页面 (src/pages/login/login.vue)
+- 导入了LoginService类
+- 改进了登录逻辑，使用async/await处理异步操作
+- 添加了更完善的错误处理
+- 增加了登录状态检查功能
+- 改进了页面跳转逻辑，使用reLaunch确保清除导航栈
+
+### 3. 更新了首页 (src/pages/home/index.vue)
+- 添加了登录状态检查
+- 正确显示登录用户信息
+- 添加了登出功能
+- 改进了用户信息加载逻辑
+
+### 4. 主要功能特性
+
+#### 登录验证
+- 用户ID必须是6位数字
+- 密码不能为空
+- 必须同意用户协议
+- 表单验证完善
+
+#### 登录状态管理
+- 自动检查登录状态
+- 已登录用户直接跳转到首页
+- 未登录用户自动跳转到登录页
+- 登录状态持久化存储
+
+#### 用户体验
+- 登录过程中显示加载状态
+- 登录成功后显示成功提示
+- 记住密码功能
+- 多语言支持
+
+#### 安全性
+- Token过期检查
+- 登录状态验证
+- 安全的登出功能
+
+## 使用方法
+
+1. 启动项目：
+```bash
+npm run dev
+```
+
+2. 登录测试：
+   - 输入6位数字用户ID（如：123456）
+   - 输入密码（至少6位）
+   - 勾选同意协议
+   - 点击登录按钮
+
+3. 功能验证：
+   - 登录成功后自动跳转到首页
+   - 首页显示用户信息
+   - 点击右上角"登出"按钮可以退出登录
+
+## 技术栈
+- Vue.js 3
+- uni-app
+- ES6+ (async/await)
+- 面向对象编程 (OOP)
+
+## 文件结构
+```
+src/
+├── api/
+│   └── login.js          # 登录服务类
+├── pages/
+│   ├── login/
+│   │   └── login.vue     # 登录页面
+│   └── home/
+│       └── index.vue     # 首页
+└── utils/
+    └── request.js        # 请求工具
+```
+
+## 注意事项
+- 当前使用模拟登录，实际项目中需要替换为真实的API调用
+- 登录状态存储在本地，实际项目中建议使用更安全的存储方式
+- 可以根据需要调整登录验证规则和UI样式
