- 新增storage_service.py封装MinIO操作 - 修改upload.py使用storage_service上传文件 - 修改course_service.py使用storage_service删除文件 - 适配preview.py支持从MinIO获取文件 - 适配knowledge_analysis_v2.py支持MinIO存储 - 在config.py添加MinIO配置项 - 添加minio依赖到requirements.txt 支持特性: - 自动降级到本地存储(MinIO不可用时) - 保持URL格式兼容(/static/uploads/) - 文件自动缓存到本地(用于预览和分析) Co-authored-by: Cursor <cursoragent@cursor.com>
