CloakBrowser 是一个 C++ 源码级修改指纹的 Chromium，reCAPTCHA v3 得分 0.9，可过 Cloudflare Turnstile。
from cloakbrowser import launch
browser = launch(headless=True)
page = browser.new_page()
page.set_viewport_size({"width": 1920, "height": 1080})
all_videos = []
def handle_response(response):
url = response.url

all_videos.append({

'duration': item.get('duration', 0),

| 端点 | 用途 |
|---|---|
/aweme/v2/web/module/feed/ | 推荐 Feed（count=20, 滚动翻页） |
/aweme/v1/web/aweme/detail/ | 单视频详情（参数: aweme_id） |
/aweme/v1/web/hot/search/list/ | 热搜榜单 |
/aweme/v2/web/module/feed/ (参数 module_id=3003101)/search/{keyword}）在 CloakBrowser 中会触发 EPIPE 崩溃（Node.js write EPIPE，原因可能是 WebSocket/SSE 连接被切断）Douyin 搜索 API (/aweme/v1/web/general/search/single/) 受到严格的 X-Bogus/A-Bogus 签名保护：
sessionid、sid_guard、passport_csrf_token），未签名的请求也会返回 verify_check 验证码--search 功能同样受此限制（内部有签名逻辑但仍可能失败）立即下载: 视频 URL 包含 x-expires 参数，有时效性（通常几分钟到几小时）
文件大小: 典型视频 40-400MB，大文件（>100MB）GitHub 无法接受
Referer Headers: 下载时必须带 Referer: https://www.douyin.com/
Proxy 冲突: 在 WSL 环境下 no_proxy='*' 会阻止 CloakBrowser 访问网络，删除 proxy 环境变量即可
视频 URL 有时效性签名（URL 中的 x-expires 参数），需即时下载
下载时需带 Referer 头 https://www.douyin.com/
首次启动 CloakBrowser 会自动下载 ~200MB Chromium 二进制到 ~/.cache/cloakbrowser/
视频可能很大（10-100MB+），建议转码压缩后再用于 demo

Use CloakBrowser (anti-detection Chromium) to access protected Chinese web platforms (Douyin/抖音, etc.) and extract structured data — intercepting API responses, extracting video/media URLs, and downloading content from sites that block standard Playwright/browser automation.
