## 前端生产级健壮性提升计划
|
||||
|
||||
### 1. 核心改进点
|
||||
|
||||
#### 添加刷新按钮
|
||||
- 在下载区域标题旁添加刷新按钮
|
||||
- 点击按钮重新加载App列表
|
||||
- 保持与现有按钮风格一致
|
||||
|
||||
#### 增强API调用健壮性
|
||||
- 统一API请求处理,添加错误处理
|
||||
- 完善各种错误场景的用户反馈
|
||||
- 添加加载状态提示
|
||||
- 处理网络错误和超时情况
|
||||
|
||||
#### 改进用户体验
|
||||
- 添加操作成功/失败的视觉反馈
|
||||
- 优化表单验证
|
||||
- 改进文件上传反馈
|
||||
|
||||
#### 前后端适配协调
|
||||
- 确保前端请求与后端API完全匹配
|
||||
- 处理后端返回的各种响应状态
|
||||
- 优化数据处理逻辑
|
||||
|
||||
### 2. 实现细节
|
||||
|
||||
#### 文件修改
|
||||
1. **index.html**
|
||||
- 在下载区域标题旁添加刷新按钮
|
||||
- 添加加载状态指示器
|
||||
|
||||
2. **script.js**
|
||||
- 添加`refreshAppList()`函数
|
||||
- 统一API请求处理函数
|
||||
- 完善错误处理逻辑
|
||||
- 添加加载状态管理
|
||||
- 优化现有函数,确保与后端API适配
|
||||
|
||||
3. **style.css**
|
||||
- 微调样式以适应刷新按钮
|
||||
- 添加加载状态样式
|
||||
|
||||
#### 关键功能实现
|
||||
- **刷新功能**:点击按钮调用`loadAppList()`重新加载App列表
|
||||
- **API健壮性**:添加try-catch、错误状态码处理、超时处理
|
||||
- **用户反馈**:添加加载中提示、操作结果反馈
|
||||
- **表单验证**:增强对输入的验证,防止无效请求
|
||||
|
||||
### 3. 保持极简风格
|
||||
- 不添加复杂UI元素
|
||||
- 保持现有配色和布局
|
||||
- 使用原生JavaScript实现
|
||||
- 不引入额外库
|
||||
|
||||
### 4. 预期效果
|
||||
- 前端与后端API适配更协调
|
||||
- 提供更好的用户反馈和错误处理
|
||||
- 添加刷新功能方便用户手动更新App列表
|
||||
- 提升系统整体健壮性和用户体验
|
||||
|
||||
### 5. 测试要点
|
||||
- 刷新功能正常工作
|
||||
- API请求错误处理
|
||||
- 网络异常情况处理
|
||||
- 各种边界情况测试
|
||||
- 保持极简风格不变
