pyppeteer

问题 I was using selenium + chrome driver for my python telegram bot deployed on linux server with docker. Everything is working, but its not supporting async so my app can't do anything else during scrapping. I heard about Pyppeteer, but having some troubles with getting page i need to scrape. Webpage requires me to login. Here are steps: Open page. Click on auth button: <button class="btn btn-outline-warning kt-font-dark mr-2" type="button" id="btn_auth"> <i class="fa fa-key"></i> Enter </button

问题 I'm running into this error in AWS Lambda. It appears that the devtools websocket is not up. Not sure how to fix it. Any ideas? Thanks for your time.

问题 I've written a script in python in combination with pyppeteer along with asyncio to scrape the links of different posts from its landing page and eventually get the title of each post by tracking the url leading to its inner page. The content I parsed here are not dynamic ones. However, I made use of pyppeteer and asyncio to see how efficiently it performs asynchronously . The following script goes well for some moments but then enounters an error: File "C:\Users\asyncio\tasks.py", line 526,

问题 I want to run chromium browser using auth proxy. I have this code, but chromium does not connect via the proxy. Any suggestions please? import asyncio from pyppeteer import launch async def main(): browser = await launch({'http_proxy': 'ip:port', 'headless': False }) page = await browser.newPage() await page.goto('https://www.myip.com/') await page.authenticate({'username': 'user', 'password': 'passw'}) input() await browser.close() asyncio.get_event_loop().run_until_complete(main()) EDIT:
