I am currently running PuppeteerSharp v1.19.0 to launch a browser and scrape web pages. The need has come up to be able to connect to an existing chrome instance and automate tasks. How can I achieve this one PuppeteerSharp? Via the following, I'm able to launch Chrome instead of Chromium with PuppeteersSharp but I haven't found how I'm able to connect to an existing instance of Chrome. All help is appreciated.

using PuppeteerSharp;

new BrowserFetcher().DownloadAsync(BrowserFetcher.DefaultRevision).GetAwaiter().GetResult();
_browser = Puppeteer.LaunchAsync(new LaunchOptions { Headless = false, ExecutablePath = @"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" }).GetAwaiter().GetResult();

推荐答案

首先，您需要在启用了远程调试的情况下启动Chrome.例如，如果使用标志-remote-debugging-port = 2122 启动Chrome，则可以使用 http://127.0连接到浏览器.0.1:2122 URL.

First thing, you need to launch Chrome with remote debugging enabled. If you launch Chrome, for instance, with the flag --remote-debugging-port=2122, you know that you will be able to connect to the browser using the http://127.0.0.1:2122 URL.

第二，如果要连接到现有浏览器，则需要调用 ConnectAsync ，而不是 LaunchAsync .

Second, if you want to connect to an existing browser you need to call ConnectAsync instead of LaunchAsync.

拥有所有这些.如果要做这样的事情:

Having all that. If would be a matter of doing something like this:

var browser = await Puppeteer.ConnectAsync(new ConnectOptions
{
    BrowserURL = "http://127.0.0.1:2122"
}));
