Connecting Browsers in Puppeteer

问题

Is it possible to connect a browser to puppeteer without instantiating it in puppeteer? For example, running an instance of chromium like a regular user and then connecting that to an instance of puppeteer in code?

回答1:

The answer is Yes and No.

You can connect to an existing using the connect function:

const browserURL = 'http://127.0.0.1:21222';
const browser = await puppeteer.connect({browserURL});

But, if you want to use those 2 lines you need to launch Chrome with the "--remote-debugging-port=21222 argument.

回答2:

Yes, you can. I see in the document have field: executablePath

By default, Puppeteer downloads and uses a specific version of Chromium so its API is guaranteed to work out of the box. To use Puppeteer with a different version of Chrome or Chromium, pass in the executable's path when creating a Browser instance:

const browser = await puppeteer.launch({executablePath: '/path/to/Chrome'});
