-# CloudFlare ImgBed KV 到 D1 数据库迁移指南
-
-本指南将帮助您将现有的 KV 存储数据迁移到 D1 数据库。
-
-## 迁移前准备
-
-### 1. 配置 D1 数据库
-
-首先，您需要在 Cloudflare 控制台创建一个 D1 数据库：
-
-```bash
-# 创建 D1 数据库
-wrangler d1 create imgbed-database
-
-# 执行数据库初始化脚本
-wrangler d1 execute imgbed-database --file=./database/init.sql
-```
-
-### 2. 更新 wrangler.toml
-
-在您的 `wrangler.toml` 文件中添加 D1 数据库绑定：
-
-```toml
-[[d1_databases]]
-binding = "DB"
-database_name = "imgbed-database"
-database_id = "your-database-id"
-```
-
-### 3. 备份现有数据
-
-在迁移前，强烈建议备份您的现有数据：
-
-1. 访问管理后台的系统设置 → 备份恢复
-2. 点击"备份数据"下载完整备份文件
-3. 保存备份文件到安全位置
-
-## 迁移步骤
-
-### 1. 检查迁移环境
-
-访问迁移工具检查环境：
-```
-GET /api/manage/migrate?action=check
-```
-
-确保返回结果中 `canMigrate` 为 `true`。
-
-### 2. 查看迁移状态
-
-查看当前数据统计：
-```
-GET /api/manage/migrate?action=status
-```
-
-### 3. 执行迁移
-
-开始数据迁移：
-```
-GET /api/manage/migrate?action=migrate
-```
-
-迁移过程包括：
-- 文件元数据迁移
-- 系统设置迁移
-- 索引操作迁移
-
-## 迁移后验证
-
-### 1. 检查数据完整性
-
-- 访问管理后台，确认文件列表正常显示
-- 测试文件上传功能
-- 检查系统设置是否保持不变
-
-### 2. 性能测试
-
-- 测试文件访问速度
-- 验证管理功能正常工作
-
-### 3. 功能验证
-
-- 文件上传/删除
-- 备份恢复功能
-- 用户认证
-- API Token 管理
-
-## 数据库结构说明
-
-迁移后的 D1 数据库包含以下表：
-
-### files 表
-存储文件元数据，包含以下字段：
-- `id`: 文件ID（主键）
-- `value`: 文件值（用于分块文件）
-- `metadata`: JSON格式的文件元数据
-- 其他索引字段：`file_name`, `file_type`, `timestamp` 等
-
-### settings 表
-存储系统配置：
-- `key`: 配置键（主键）
-- `value`: 配置值
-- `category`: 配置分类
-
-### index_operations 表
-存储索引操作记录：
-- `id`: 操作ID（主键）
-- `type`: 操作类型
-- `timestamp`: 时间戳
-- `data`: 操作数据
-- `processed`: 是否已处理
-
-### index_metadata 表
-存储索引元数据：
-- `key`: 元数据键
-- `last_updated`: 最后更新时间
-- `total_count`: 总文件数
-- `last_operation_id`: 最后操作ID
-
-### other_data 表
-存储其他数据（如黑名单IP等）：
-- `key`: 数据键
-- `value`: 数据值
-- `type`: 数据类型
-
-## 兼容性说明
-
-### 向后兼容
-- 系统会自动检测可用的数据库类型（D1 或 KV）
-- 如果 D1 不可用，会自动回退到 KV 存储
-- 所有现有的 API 接口保持不变
-
-### 环境变量
-- `DB`: D1 数据库绑定（新增）
-- `img_url`: KV 存储绑定（保留作为备用）
-
-## 故障排除
-
-### 常见问题
-
-1. **迁移失败**
-   - 检查 D1 数据库是否正确配置
-   - 确认数据库初始化脚本已执行
-   - 查看迁移日志中的错误信息
-
-2. **数据不完整**
-   - 检查迁移结果中的错误列表
-   - 重新运行迁移（支持增量迁移）
-   - 使用备份文件恢复数据
-
-3. **性能问题**
-   - D1 数据库查询比 KV 稍慢，这是正常的
-   - 确保使用了适当的索引
-   - 考虑优化查询语句
-
-### 回滚方案
-
-如果迁移后出现问题，可以：
-
-1. 临时禁用 D1 绑定，系统会自动回退到 KV
-2. 使用备份文件恢复到迁移前状态
-3. 重新配置和测试 D1 数据库
-
-## 性能优化建议
-
-### 1. 索引优化
-D1 数据库已预设了必要的索引，包括：
-- 文件时间戳索引
-- 目录索引
-- 文件类型索引
-
-### 2. 查询优化
-- 使用分页查询大量数据
-- 避免全表扫描
-- 合理使用 WHERE 条件
-
-### 3. 监控
-- 定期检查数据库性能
-- 监控查询执行时间
-- 关注错误日志
-
-## 支持
-
-如果在迁移过程中遇到问题，请：
-
-1. 查看浏览器控制台的错误信息
-2. 检查 Cloudflare Workers 的日志
-3. 确认所有配置正确
-4. 参考本指南的故障排除部分
-
-迁移完成后，您的图床将使用更强大的 D1 数据库，享受更好的查询性能和数据管理能力。
