- 针对APP环境优化文件下载和预览兼容性
- 添加条件编译支持不同平台的文件处理策略
- 重构按钮布局为垂直固定底部排列
- 新增APK兼容性说明文档和FTP接口文档

技术优化：
- APP环境图片预览先下载到本地避免网络问题
- 文件下载添加进度显示和存储路径指定
- 统一错误处理和用户体验优化
- CSS样式针对APP环境专项适配

包含文档：
- APK兼容性优化说明.md
- FTP文件操作接口文档-更新版.md

# APK兼容性优化说明

## ðŸŽ¯ æ¦‚è¿°
针对UniApp项目打包成Android APK时的兼容性问题，已实施全面的优化方案，确保所有功能在APP环境中正常运行。

## ðŸ”§ å·²è§£å†³çš„兼容性问题

### 1. æ–‡ä»¶é¢„览功能兼容性

#### é—®é¢˜æè¿°
- H5环境和APP环境的文件加载机制不同
- ç½‘络图片在APP中可能无法直接显示
- ä¸åŒæ–‡ä»¶ç±»åž‹éœ€è¦ä¸åŒçš„处理策略

#### è§£å†³æ–¹æ¡ˆ
```javascript
// å›¾ç‰‡é¢„览 - APP环境先下载到本地
// #ifdef APP-PLUS
uni.downloadFile({
    url: url,
    success: (res) => {
        // ä½¿ç”¨æœ¬åœ°è·¯å¾„预览
        uni.navigateTo({
            url: `/pages/fileView/imageView?url=${encodeURIComponent(res.tempFilePath)}`
        });
    }
});
// #endif

// H5环境直接使用网络URL
// #ifdef H5
uni.navigateTo({
    url: `/pages/fileView/imageView?url=${encodeURIComponent(url)}`
});
// #endif
```

### 2. æ–‡ä»¶ä¸‹è½½åŠŸèƒ½ä¼˜åŒ–

#### é—®é¢˜æè¿°
- H5环境使用blob下载，APP需要uni.downloadFile
- APP中文件存储路径和权限处理
- ä¸‹è½½è¿›åº¦æ˜¾ç¤ºå’Œç”¨æˆ·ä½“验

#### è§£å†³æ–¹æ¡ˆ
```javascript
// APP环境优化
// #ifdef APP-PLUS
const saveDir = plus.os.name === 'Android' ? 
    plus.io.convertLocalFileSystemURL('_downloads/') : 
    plus.io.convertLocalFileSystemURL('_documents/');

const downloadTask = uni.downloadFile({
    url: url,
    filePath: `${saveDir}${fileName}`, // æŒ‡å®šä¿å­˜è·¯å¾„
    success: (res) => {
        // æä¾›æ‰“开文件选项
        uni.showModal({
            title: '下载成功',
            confirmText: '打开文件',
            success: (modalRes) => {
                if (modalRes.confirm) {
                    plus.runtime.openFile(res.filePath);
                }
            }
        });
    }
});

// æ˜¾ç¤ºä¸‹è½½è¿›åº¦
downloadTask.onProgressUpdate((res) => {
    const progress = Math.round(res.progress);
    uni.showLoading({ title: `下载中 ${progress}%` });
});
// #endif
```

### 3. ç½‘络请求兼容性

#### é—®é¢˜æè¿°
- CORS问题在APP中不存在，但有其他限制
- è¯·æ±‚头和响应处理可能不同
- è¶…时和错误处理机制

#### è§£å†³æ–¹æ¡ˆ
- **APP环境**：无需处理CORS，使用原生网络请求
- **H5环境**：保留CORS处理和多种下载降级策略
- **统一错误处理**：提供友好的错误提示

### 4. UI组件适配

#### é—®é¢˜æè¿°
- å¼¹çª—在不同屏幕尺寸下的显示
- CSS样式在APP中的渲染差异
- è§¦æ‘¸äº¤äº’的优化

#### è§£å†³æ–¹æ¡ˆ
```css
/* APP环境专用样式 */
/* #ifdef APP-PLUS */
.file-preview-popup {
    width: 85vw;
    max-height: 75vh;
}
.file-preview-content {
    max-height: 350px;
}
/* #endif */
```

## ðŸš¨ é‡è¦æ›´æ–°ï¼šCORS跨域问题解决方案

### é—®é¢˜æè¿°
在H5环境中使用 `DownloadFtpFile` æŽ¥å£æ—¶å‡ºçŽ°ä»¥ä¸‹é”™è¯¯ï¼š
```
Refused to get unsafe header "content-disposition"
```

### åŽŸå› åˆ†æž
这是由于浏览器的CORS（跨域资源共享）安全策略导致的，浏览器阻止了前端访问某些HTTP响应头。

### è§£å†³æ–¹æ¡ˆ

#### åŽç«¯CORS配置（必须）
后端接口必须设置以下CORS响应头：

```http
Access-Control-Allow-Origin: *
Access-Control-Allow-Methods: GET, POST, OPTIONS
Access-Control-Allow-Headers: Content-Type, Authorization
Access-Control-Expose-Headers: Content-Disposition, Content-Length, Content-Type
```

**关键点**: `Access-Control-Expose-Headers` å¿…须包含 `Content-Disposition`，否则前端无法读取文件名信息。

#### å‰ç«¯å¤šçŽ¯å¢ƒå…¼å®¹ï¼ˆå·²å®žçŽ°ï¼‰
前端代码已更新为多环境兼容：

1. **H5环境**: ä½¿ç”¨å¤šç§ä¸‹è½½æ–¹å¼çš„降级策略
   - æ–¹æ³•1: `<a>` æ ‡ç­¾ä¸‹è½½
