What problem does it solve?

CDP网页数据提取需要稳定的浏览器会话和可重复的数据抓取流程，避免直接HTTP请求导致的反爬和数据不一致。

Core Features & Use Cases

  • 通过 CDP 连接到已开启远程调试端口的浏览器，提取页面 DOM/HTML，输出纯 JSON，供 Agent 分析。
  • 支持 JavaScript 渲染页面，确保动态内容可获取；可用于趋势、监控和数据收集场景。
  • 使用场景包括在已登录会话中抓取商品、文章或新闻等页面的结构化数据，并将结果传递给后续流程。

Quick Start

Open a browser with CDP on port 9222 and run the web-do extraction script against a target page to obtain JSON.
