Connect with pyppeteer to existing chrome

问题 I want to connect to an existing (already opened) chrome browser with pyppeteer so I would be able to control it. I can do almost every manual action before (for example, enabling remote debugging mode in existing chrome), but it is preferable to do it with the least actions. In order to use browser.connect , I need to give it browserWSEndpoint , which is equivalent to webSocketDebuggerUrl under 'http://localhost:9222/json/version'. My problem is that I can get to 'http://localhost:9222/json

问题 I was doing some tests and I wonder if the script below is running asynchronously? # python test.py It took 1.3439464569091797 seconds. 31 (sites) x 1.34 = 41.54s - so it's a few seconds less but in theory it should take only as long as the longest request? # python test.py It took 28.129364728927612 seconds. Perhaps opening a browser is not async here and I should use executor for this? # cat test.py import asyncio import time from pyppeteer import launch from urllib.parse import urlparse
