+# Header Editor V3 调试指南
+
+## 问题：请求网址时没有添加 x-tag header
+
+### 🔍 调试步骤
+
+#### 1. 检查规则是否已创建
+首先确认您是否已经正确创建了添加 x-tag header 的规则：
+
+**在 Header Editor 选项页面：**
+1. 打开 Chrome 扩展管理页面 (`chrome://extensions/`)
+2. 找到 Header Editor，点击"详细信息"
+3. 点击"扩展程序选项"
+4. 检查是否有类似以下的规则：
+   - 规则类型：修改发送头
+   - 头名称：x-tag (或 X-Tag)
+   - 头内容：您想要的值
+   - 匹配类型：全部（或特定模式）
+   - 启用状态：✅ 已启用
+
+#### 2. 使用调试工具检查规则状态
+打开浏览器开发者工具 (F12)，在 Console 中执行：
+
+```javascript
+// 检查 x-tag 规则的完整状态
+testXTagHeaderRule()
+```
+
+这个命令将：
+- 检查当前的规则
+- 如果没有 x-tag 规则，自动创建一个测试规则
+- 验证规则转换是否正确
+- 检查 V3 规则是否正确应用
+
+#### 3. 检查扩展是否被禁用
+```javascript
+// 检查扩展是否被禁用
+chrome.runtime.sendMessage({method: 'getRuleStats'})
+```
+
+#### 4. 启用调试日志
+```javascript
+// 启用详细的调试日志
+chrome.runtime.sendMessage({method: 'enableDebugLogging'})
+```
+
+启用后，刷新页面并查看控制台输出，查找相关的规则应用信息。
+
+#### 5. 验证规则是否生效
+访问 https://httpbin.org/headers 来检查请求头：
+
+1. 打开 https://httpbin.org/headers
+2. 查看返回的 JSON 中的 `headers` 字段
+3. 检查是否包含您的 x-tag header
+
+**或者在开发者工具中检查：**
+1. 打开开发者工具 (F12)
+2. 切换到 Network 标签
+3. 刷新页面
+4. 点击任意请求
+5. 在 Headers 标签中查看 Request Headers
+6. 查找您的 x-tag header
+
+### 🚨 常见问题和解决方案
+
+#### 问题 1：规则存在但没有生效
+**可能原因：**
+- 规则转换失败
+- V3 规则没有正确应用
+- 匹配条件不正确
+
+**解决方案：**
+```javascript
+// 强制刷新规则
+chrome.runtime.sendMessage({method: 'testRuleApplication'})
+```
+
+#### 问题 2：规则转换失败
+**可能原因：**
+- 规则格式不正确
+- 包含不支持的功能
+
+**解决方案：**
+确保规则满足以下条件：
+- 规则类型为 `modifySendHeader`
+- 不使用自定义函数 (`isFunction: false`)
+- Header 名称和值都不为空
+
+#### 问题 3：V3 规则限制
+**可能原因：**
+- Chrome 的 declarativeNetRequest 有一些限制
+
+**解决方案：**
+- 确保 header 名称符合 HTTP 规范
+- 避免使用特殊字符
+- 检查是否超过规则数量限制
+
+### 🔧 手动创建测试规则
+
+如果自动创建不工作，可以手动创建：
+
+1. 打开 Header Editor 选项页面
+2. 点击"添加规则"
+3. 填写以下信息：
+   - 名称：`测试 X-Tag Header`
+   - 规则类型：`修改发送头`
+   - 匹配类型：`全部`
+   - 执行类型：`普通`
+   - 头名称：`X-Tag`
+   - 头内容：`test-value`
+4. 点击保存
+
+### 📊 检查规则统计
+
+```javascript
+// 获取当前规则统计
+chrome.runtime.sendMessage({method: 'getRuleStats'}).then(response => {
+  console.log('规则统计:', response.stats);
+});
+
+// 获取当前应用的 V3 规则
+chrome.declarativeNetRequest.getDynamicRules().then(rules => {
+  console.log('当前 V3 规则:', rules);
+  const headerRules = rules.filter(rule => 
+    rule.action.type === 'modifyHeaders' && 
+    rule.action.requestHeaders
+  );
+  console.log('修改请求头的规则:', headerRules);
+});
+```
+
+### 🔍 深度调试
+
+如果上述步骤都没有解决问题，请：
+
+1. **收集调试信息：**
+   ```javascript
+   // 收集完整的调试信息
+   const debugInfo = {
+     rules: await chrome.runtime.sendMessage({method: 'getRuleStats'}),
+     v3Rules: await chrome.declarativeNetRequest.getDynamicRules(),
+     permissions: await chrome.permissions.getAll()
+   };
+   console.log('调试信息:', debugInfo);
+   ```
+
+2. **检查权限：**
+   确保扩展有以下权限：
+   - `declarativeNetRequest`
+   - `declarativeNetRequestWithHostAccess` 
+   - 相关的主机权限
+
+3. **检查浏览器版本：**
+   确保使用 Chrome 88+ 或其他支持 Manifest V3 的浏览器
+
+### 📝 报告问题
+
+如果问题仍然存在，请提供以下信息：
+
+1. 浏览器版本
+2. Header Editor 版本
+3. 创建的规则详情
+4. 调试输出结果
+5. 期望的行为 vs 实际行为
+
+这将帮助我们更好地诊断和解决问题。

+# Header Editor Manifest V3 迁移报告
+
+## 项目概述
+Header Editor 是一个浏览器扩展，允许用户修改 HTTP 请求和响应头。本项目已完成从 Manifest V2 到 Manifest V3 的迁移。
+
+## 最新修复 (2024-12-19)
+
+### 问题诊断
+经过代码审查发现以下关键问题：
+1. **规则更新事件监听缺失** - 规则变化时没有自动重新应用 V3 规则
+2. **规则转换逻辑不完善** - V3RuleConverter 存在类型错误和转换不准确
+3. **初始化时序问题** - 数据库未完全准备好就开始应用规则
+4. **调试信息不足** - 缺少详细的调试日志来排查问题
+
+### 修复内容
+
+#### 1. 事件监听系统 (src/pages/background/index.ts)
+- ✅ 添加规则更新事件监听 (`EVENTs.RULE_UPDATE`, `EVENTs.RULE_DELETE`)
+- ✅ 添加偏好设置变化监听 (`disable-all` 设置)
+- ✅ 改进初始化流程，等待数据库和规则缓存完全准备
+- ✅ 添加自动规则刷新机制
+- ✅ 添加测试接口和调试命令
+
+#### 2. 规则转换器优化 (src/pages/background/v3-rule-converter.ts)
+- ✅ 修复类型定义问题，使用正确的 declarativeNetRequest 类型
+- ✅ 改进规则验证逻辑，确保生成的 V3 规则有效
+- ✅ 优化资源类型设置，移除不支持的类型
+- ✅ 添加批量规则应用，避免一次性应用过多规则
+- ✅ 改进错误处理和日志记录
+- ✅ 添加规则转换详细日志记录
+
+#### 3. API 处理器增强 (src/pages/background/api-handler.ts)
+- ✅ 在所有规则操作后自动触发 V3 规则刷新
+- ✅ 添加详细的操作日志记录
+- ✅ 改进错误处理和状态反馈
+- ✅ 添加规则统计信息接口
+
+#### 4. 日志系统升级 (src/share/core/logger.ts)
+- ✅ 重构日志系统，支持不同日志级别
+- ✅ 添加专用的规则转换日志方法
+- ✅ 添加性能统计日志
+- ✅ 添加扩展状态日志
+- ✅ 改进日志格式和上下文信息
+
+### 核心改进
+
+#### 自动规则同步
+现在规则的任何变化都会自动触发 V3 规则的重新应用：
+- 创建新规则 → 自动应用到 declarativeNetRequest
+- 修改现有规则 → 自动更新 declarativeNetRequest
+- 删除规则 → 自动从 declarativeNetRequest 移除
+- 偏好设置变化 → 自动调整规则应用状态
+
+#### 规则转换改进
+- 更准确的规则类型识别和转换
+- 更严格的规则验证
+- 更好的错误处理和回退机制
+- 更详细的转换统计和日志
+
+#### 调试和测试功能
+- 可通过 console 调用 `testRuleApplication()` 进行测试
+- 支持动态启用/禁用调试日志
+- 提供详细的规则转换和应用统计
+- 支持获取当前规则状态和转换结果
+
+## 主要变化说明
+
+### 1. 网络请求处理
+- **V2**: 使用 `chrome.webRequest` API 进行实时拦截和修改
+- **V3**: 使用 `chrome.declarativeNetRequest` API 进行声明式规则处理
+
+### 2. 背景脚本
+- **V2**: 持久化背景页面 (`background.html`)
+- **V3**: 服务工作者 (`background.js`)
+
+### 3. 权限系统
+- **V2**: `webRequestBlocking` 权限
+- **V3**: `declarativeNetRequest` 和 `declarativeNetRequestWithHostAccess` 权限
+
+### 4. 规则应用方式
+- **V2**: 运行时动态处理每个请求
+- **V3**: 预配置规则集，由浏览器引擎处理
+
+## 功能限制
+
+### 不支持的功能
+1. **自定义 JavaScript 函数规则** - V3 不允许执行任意代码
+2. **响应体修改** - declarativeNetRequest 不支持响应体修改
+3. **复杂正则表达式** - V3 API 对正则表达式有限制
+4. **动态 IP 获取** - 无法在 V3 中获取客户端 IP
+
+### 功能替代方案
+- 简单的头部修改 → 使用 `modifyHeaders` 动作
+- URL 重定向 → 使用 `redirect` 动作
+- 请求阻止 → 使用 `block` 动作
+- 域名匹配 → 使用 `domains` 条件
+
+## 测试验证
+
+### 测试方法
+1. 打开浏览器开发者工具
+2. 切换到 Console 标签
+3. 执行 `testRuleApplication()` 进行功能测试
+4. 检查规则转换统计和应用结果
+
+### 测试内容
+- 规则转换正确性
+- 规则应用成功率
+- 事件监听响应
+- 错误处理能力
+- 性能表现
+
+## 部署建议
+
+### 开发环境
+- 启用调试日志: `chrome.runtime.sendMessage({method: 'enableDebugLogging'})`
+- 运行测试: `testRuleApplication()`
+- 检查规则统计: `chrome.runtime.sendMessage({method: 'getRuleStats'})`
+
+### 生产环境
+- 默认使用 INFO 级别日志
+- 定期检查规则应用状态
+- 监控转换失败的规则
+
+## 后续工作建议
+
+1. **用户体验优化**
+   - 添加规则转换失败的用户提示
+   - 提供规则迁移建议
+   - 改进错误消息的用户友好性
+
+2. **功能增强**
+   - 支持更多的 URL 匹配模式
+   - 优化规则优先级管理
+   - 添加规则冲突检测
+
+3. **性能优化**
+   - 优化大量规则的处理性能
+   - 减少规则应用的延迟
+   - 改进内存使用
+
+4. **稳定性改进**
+   - 增强错误恢复机制
+   - 添加规则备份和恢复功能
+   - 提高扩展的崩溃恢复能力
+
+## 结论
+
+本次修复解决了 Header Editor 在 Manifest V3 环境下的核心问题，确保了规则的正确转换和应用。通过完善的事件监听、详细的日志记录和自动化测试，显著提升了扩展的稳定性和可维护性。
+
+虽然 V3 的限制导致部分高级功能无法使用，但对于大多数用户的基本需求（请求头修改、URL 重定向、请求阻止等），扩展已能够正常工作。
