-# douyin_cookie_yunsya
+# 抖音 Cookie 一键提取

-提取抖音cookies
+扫码登录抖音后，自动导出 JSON 格式 Cookie。
+
+## 原理
+
+采用 **HTTP SSO 接口**（无需 Playwright / 浏览器）：
+
+1. 注册 `ttwid` 设备标识
+2. 调用 `passport/web/get_qrcode` 或 `sso.douyin.com/get_qrcode` 获取二维码
+3. 轮询 `check_qrconnect` 检测扫码状态
+4. 确认后跟随 `redirect_url` 完成会话，导出 Cookie
+
+> 若服务器 IP 被抖音风控（错误码 4031），请配置**住宅代理 API**。
+
+### 与其他方案对比
+
+| 方案 | 说明 | 本项目 |
+|------|------|--------|
+| HTTP SSO | 逆向 passport 接口，轻量快速 | **当前采用** |
+| Playwright | 模拟浏览器，重、易碎 | 已移除 |
+| 开放平台 OAuth | 需注册应用，返回 access_token 非网页 Cookie | 不适用 |
+
+## 环境要求
+
+- Python 3.9+
+- Node.js 18+（仅构建前端时需要）
+
+## 安装
+
+```bash
+pip install -r requirements.txt
+
+cd frontend
+npm install
+npm run build
+```
+
+## 运行
+
+```bash
+py -3 app.py
+```
+
+访问：http://127.0.0.1:5001
+
+## 环境变量
+
+| 变量 | 默认值 | 说明 |
+|------|--------|------|
+| `PORT` | `5001` | 服务端口 |
+| `LOGIN_TIMEOUT` | `600` | 登录超时（秒） |
+| `QR_POLL_INTERVAL` | `2` | 建议前端轮询间隔 |
+| `DOUYIN_AID` | `6383` | 抖音 Web 应用 ID |
+| `DOUYIN_SERVICE` | `https://www.douyin.com` | SSO service 参数 |
+
+## API
+
+| 接口 | 说明 |
+|------|------|
+| `POST /api/start_qr` | 获取二维码（HTTP SSO） |
+| `GET /api/check_login` | 轮询扫码/登录状态 |
+| `POST /api/reset` | 重置会话 |
+| `GET /api/debug` | SSO 轮询调试信息 |
+| `POST /api/test_proxy` | 测试代理 |
+
