+# 代理通信协议设计文档
+
+## 1. 架构概述
+
+### 1.1 设备角色
+
+| 设备 | 角色 | 能力 | 限制 |
+|------|------|------|------|
+| 电脑A | 代理客户端 | 可访问内网网站，作为HTTP客户端 | 无法监听端口 |
+| 电脑B | 代理服务器 | 可监听端口，转发HTTP请求 | 无法直接访问内网 |
+
+### 1.2 网络拓扑
+
+```
+浏览器 <--(端口8081)--> 电脑B <--(端口8080)--> 电脑A <--(HTTP)--> 目标网站
+```
+
+### 1.3 核心设计原则
+
+1. **电脑A作为纯HTTP客户端**：不保存cookie、session等状态信息
+2. **请求头替换**：电脑A强制替换Origin、Referer等参数
+3. **日志对应**：server端每一条请求日志，client端对应一条请求日志
+4. **目标网站硬编码**：目标网站地址写死在配置中
+
+---
+
+## 2. 端口分配
+
+| 端口号 | 用途 | 连接方向 |
+|--------|------|----------|
+| 8080 | 设备A连接端口 | 电脑A → 电脑B |
+| 8081 | 浏览器访问端口 | 浏览器 → 电脑B |
+
+---
+
+## 3. 通信协议
+
+### 3.1 协议类型
+
+采用 **自定义HTTP代理协议**，电脑B将浏览器请求转发给电脑A，电脑A作为HTTP客户端访问目标网站。
+
+### 3.2 协议流程
+
+#### 阶段1：设备A连接到设备B
+
+```
+电脑A → 电脑B: TCP连接建立
+电脑B → 电脑A: "PROXY_CONNECTED\r\n"
+电脑A → 电脑B: "READY\r\n"
+```
+
+#### 阶段2：浏览器发起请求
+
+```
+浏览器 → 电脑B: 完整HTTP请求
+GET /max/js/jquery/lib.js HTTP/1.1
+Host: localhost:8081
+Origin: http://localhost:8081
+Referer: http://localhost:8081/
+[其他请求头...]
+
+[请求体（如有）]
+```
+
+#### 阶段3：电脑B转发请求
+
+```
+电脑B → 电脑A: 完整HTTP请求（透传）
+```
+
+#### 阶段4：电脑A处理请求
+
+1. **修改请求头**：替换Origin、Referer为目标网站地址
+2. **修改Host头**：设置为目标网站地址
+3. **移除不必要的头**：如Connection、Keep-Alive等
+
+#### 阶段5：电脑A访问目标网站
+
+```
+电脑A → 内网目标: 修改后的HTTP请求
+GET /max/js/jquery/lib.js HTTP/1.1
+Host: zentao.sunyard.com.cn:9788
+Origin: http://zentao.sunyard.com.cn:9788
+Referer: http://zentao.sunyard.com.cn:9788/
+[其他请求头...]
+
+[请求体（如有）]
+```
+
+#### 阶段6：电脑A返回响应
+
+```
+内网目标 → 电脑A: HTTP响应
+电脑A → 电脑B: HTTP响应（透传）
+电脑B → 浏览器: HTTP响应（透传）
+```
+
+#### 阶段7：连接保持
+
+- 电脑A与电脑B保持长连接
+- 支持同一连接上的多个HTTP请求
+- 连接空闲超时时间：300秒
+
+---
+
+## 4. 请求头处理规则
+
+### 4.1 强制替换的请求头
+
+| 请求头 | 替换值 |
+|--------|--------|
+| Origin | `http://{TARGET_HOST}:{TARGET_PORT}` |
+| Referer | `http://{TARGET_HOST}:{TARGET_PORT}/` |
+| Host | `{TARGET_HOST}:{TARGET_PORT}` |
+
+### 4.2 移除的请求头
+
+| 请求头 | 原因 |
+|--------|------|
+| Connection | 由电脑A管理连接 |
+| Keep-Alive | 由电脑A管理连接 |
+| Proxy-Connection | 不需要代理标识 |
+| X-Forwarded-For | 不需要转发标识 |
+
+### 4.3 保留的请求头
+
+所有其他请求头保持不变，包括：
+- Accept
+- Accept-Encoding
+- Accept-Language
+- User-Agent
+- Cookie（如果有）
+- Content-Type
+- Content-Length
+
+---
+
+## 5. 数据格式
+
+### 5.1 请求格式
+
+电脑B转发给电脑A的请求格式为**完整的HTTP请求**：
+
+```
+{HTTP_METHOD} {REQUEST_PATH} HTTP/1.1\r\n
+{HEADER_NAME}: {HEADER_VALUE}\r\n
+...
+\r\n
+{REQUEST_BODY}
+```
+
+### 5.2 响应格式
+
+电脑A返回给电脑B的响应格式为**完整的HTTP响应**：
+
+```
+HTTP/1.1 {STATUS_CODE} {STATUS_MESSAGE}\r\n
+{HEADER_NAME}: {HEADER_VALUE}\r\n
+...
+\r\n
+{RESPONSE_BODY}
+```
+
+---
+
+## 6. 日志规范
+
+### 6.1 日志格式
+
+| 字段 | 格式 | 示例 |
+|------|------|------|
+| 时间戳 | `YYYY-MM-DD HH:MM:SS` | `2024-01-15 10:30:45` |
+| 级别 | `[INFO]` / `[ERROR]` | `[INFO]` |
+| 来源 | `[Browser]` / `[DeviceA]` / `[System]` | `[Browser]` |
+| 行号 | `(line N)` | `(line 45)` |
+| 内容 | 描述信息 | 请求详情 |
+
+### 6.2 请求日志（电脑B）
+
+```
+[时间戳] [INFO] [Browser] (line N) Request: {METHOD} {PATH} - Body: {BYTES} bytes
+```
+
+### 6.3 请求日志（电脑A）
+
+```
+[时间戳] [INFO] [System] (line N) Request: {METHOD} {PATH} - Body: {BYTES} bytes
+```
+
+### 6.4 响应日志（电脑B）
+
+```
+[时间戳] [INFO] [Browser] (line N) Response: {METHOD} {PATH} - Status: {CODE} - Time: {MS}ms
+```
+
+### 6.5 响应日志（电脑A）
+
+```
+[时间戳] [INFO] [System] (line N) Response: {METHOD} {PATH} - Status: {CODE} - Time: {MS}ms
+```
+
+### 6.6 日志对应原则
+
+**server端有一条请求日志，client端必须有一条对应的请求日志**：
+
+```
+电脑B: [2024-01-15 10:30:45] [INFO] [Browser] (line 45) Request: GET /max/js/jquery/lib.js - Body: 0 bytes
+电脑A: [2024-01-15 10:30:45] [INFO] [System] (line 35) Request: GET /max/js/jquery/lib.js - Body: 0 bytes
+```
+
+---
+
+## 7. 错误处理
+
+### 7.1 设备A未连接
+
+当浏览器请求时设备A未连接：
+
+```
+HTTP/1.1 503 Service Unavailable
+Content-Type: text/plain
+
+Device A not connected
+```
+
+### 7.2 目标不可达
+
+当电脑A无法连接目标网站：
+
+```
+HTTP/1.1 502 Bad Gateway
+Content-Type: text/plain
+
+Cannot connect to target: zentao.sunyard.com.cn:9788
+```
+
+### 7.3 重复连接
+
+当已有设备A连接时，拒绝新连接：
+
+```
+ERROR: Another A device is already connected
+```
+
+### 7.4 请求超时
+
+当请求处理超时：
+
+```
+HTTP/1.1 504 Gateway Timeout
+Content-Type: text/plain
+
+Request timeout
+```
+
+---
+
+## 8. 超时设置
+
+| 操作 | 超时时间 |
+|------|----------|
+| 设备A连接超时 | 10秒 |
+| 目标网站连接超时 | 30秒 |
+| 请求处理超时 | 60秒 |
+| 连接空闲超时 | 300秒 |
+
+---
+
+## 9. 配置参数
+
+### 9.1 电脑A配置
+
+| 参数 | 说明 | 默认值 |
+|------|------|--------|
+| TARGET_HOST | 目标内网网站主机 | zentao.sunyard.com.cn |
+| TARGET_PORT | 目标内网网站端口 | 9788 |
+| B_HOST | 电脑B地址 | localhost |
+| B_PORT | 电脑B端口 | 8080 |
+
+### 9.2 电脑B配置
+
+| 参数 | 说明 | 默认值 |
+|------|------|--------|
+| A_PORT | 设备A连接端口 | 8080 |
+| BROWSER_PORT | 浏览器访问端口 | 8081 |
