fix: 修复 Alpine 环境 MIME 类型检测和非 HTTPS 剪贴板功能
后端修复:
- 添加常见 MIME 类型的 fallback 映射表(video/mp4, audio/mp3, image/jpeg等)
- 解决 Alpine Linux 缺少 /etc/mime.types 导致文件扩展名检测失败问题
- 增强日志输出,便于调试文件类型检测流程
前端修复:
- 修复非安全上下文(http://192.168.x.x)下剪贴板功能失效问题
- 改进 execCommand 回退方案: 移除 readonly 属性,调整 textarea 定位
- 修复文本选中问题,确保实际复制到剪贴板
- 添加详细调试日志
- 保存并恢复原始文本选区
部署优化:
- Dockerfile 添加 mailcap 包安装 MIME 数据库
- 统一设置 UTF-8 环境变量(LANG, LC_ALL)
- supervisord 为所有程序配置 UTF-8 环境
根因分析:
- 后端: Alpine 缺少 mime.types 导致 mime.ExtensionsByType 返回空数组
- 前端: navigator.clipboard 仅在安全上下文可用,execCommand 方案存在 textarea 选中问题1 parent e508ff7 commit 8c5d603
