问题 When I run Puppeteer on Cloud Functions with Node 8, I get this error. Error: Failed to launch chrome! [1205/063825.588245:ERROR:zygote_host_impl_linux.cc(89)] Running as root without --no-sandbox is not supported. See https://crbug.com/638180. Launching Puppeteer with browser = await puppeteer.launch({ args: ['--no-sandbox'], headless: true }) solves the issue.

Headless Chrome - Sharing Credentials

五迷三道 提交于 2020-12-13 07:34:28
问题 I would like to automate printing a number of URLs. Headless Chrome works beautifully here ... chrome --headless --disable-gpu --print-to-pdf="C:\tmp\test.pdf" https://time.com/ Except that the real site I want to run this on requires authentication. I was hoping that headless Chrome would share cookies with Chrome and therefore all will be hunky-dory. But I am wrong. The print indicates that JavaScript are cookies are disabled, so I can't print what I want. Appreciate if someone could help

How to bundle headless chromium module with AWS Lambda?

回眸只為那壹抹淺笑 提交于 2020-12-12 10:25:28
问题 I'm attempting to use Puppeteer with Lambda, however, on serverless deploy, the lambda errors out due to exceeding the 250mb unbundled package size limit. So, to get under the limit, I've switched to Puppeteer core which doesn't come packaged with chromium. This requires referencing a path to an executable to launch chrome. (e.g. puppeteer.launch({executablePath: headlessChromiumPath}) ); However, I'm not sure how to load a headless Chromium into my container so that I can later reference it.

Possible to Get Puppeteer Audio Feed and/or Input Audio Directly to Puppeteer?

霸气de小男生 提交于 2020-12-01 10:42:26
问题 I want to input WAV or MP3 into puppeteer as a microphone, however while in headless the application is muted, so I was wondering if there was a way to get input directly into the browser. I am also wondering if it's possible to get a feed of audio from the browser while in headless, and/or record the audio and place it in a folder. 回答1: I ended up using this solution. First, I enabled some options for Chromium: const browser = await puppeteer.launch({ args: [ '--use-fake-ui-for-media-stream'
