From acbdc1f29b268f37a6130f78edb14803b109b052 Mon Sep 17 00:00:00 2001 From: Kris Ka Date: Mon, 15 Sep 2025 12:07:09 +0800 Subject: [PATCH] =?UTF-8?q?=E5=AE=8C=E6=88=90=E9=A1=B9=E7=9B=AE=E9=97=AE?= =?UTF-8?q?=E9=A2=98=E4=BF=AE=E5=A4=8D=E5=92=8C=E4=BC=98=E5=8C=96?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 主要改进: 1. 清理重复文件和冗余代码 - 删除重复的API文件 (upload_backup.py, upload_new.py等) - 删除旧版本的B站服务文件 (bilibili_upload_v2.py到v6.py) - 统一B站服务接口 2. 优化数据存储架构 - 创建OptimizedStorageService解决双重存储问题 - 数据库只存储元数据，文件系统存储实际文件 - 提供数据迁移脚本和一致性检查工具 3. 统一错误处理机制 - 创建统一错误处理中间件 - 提供错误处理装饰器和上下文管理器 - 统一错误响应格式 4. 完善配置管理 - 创建UnifiedConfig统一配置系统 - 整合所有配置源(环境变量、配置文件、默认值) - 提供配置迁移脚本 5. 增强进度系统 - 创建EnhancedProgressService - 支持Redis缓存、数据库持久化和内存缓存 - 提供完整的进度跟踪和状态管理 新增文件: -
