Puppeteer 连接 chrome 浏览器远程调试链接（localhost:9222）时出现 404 错误，如何解决？

Question

我正在使用以下代码在现有浏览器窗口上使用 puppeteer：

    const browser = await puppeteer.connect({
      browserWSEndpoint: 'ws://localhost:9222'
    });

我已经启动了一个 Chrome 窗口，并使用此命令进行调试：

"C:\Program Files\Google\Chrome\Application\chrome.exe" -remote-debugging-port=9222

为了确认调试是否正常工作，我在 Chrome 窗口中打开了链接 localhost:9222，它打开了一个空白页面，没有错误。

但是，运行 puppeteer 代码来连接到此打开的 Chrome 浏览器实例会出现以下错误：

您能帮我了解导致 404 错误的原因以及如何在 chrome 浏览器上成功建立远程调试吗？

更多信息：我的操作系统是 Windows 11。

我尝试使用 127.0.0.1 代替，它导致了相同的行为： Puppeteer 给出 404，但在 chrome 浏览器中打开成功

Answer 1

就像这对我有用：

const browser = await puppeteer.connect({
  browserURL: 'http://127.0.0.1:9222'
})
