由 限于喜欢 提交于 2019-12-07 06:47:45
问题 I am trying to do some automation with the rather new GoogleChrome/puppeteer library, but I cannot figure out how to set a value in a select field.

问题 I've read about the Chrome Headless from developers.google said we can run the Google without UI. Quote from that link : Headless Chrome is shipping in Chrome 59. It's a way to run the Chrome browser in a headless environment. Essentially, running Chrome without chrome! It brings all modern web platform features provided by Chromium and the Blink rendering engine to the command line. Why is that useful? A headless browser is a great tool for automated testing and server environments where you

Selenium with chromedriver gives different results based on “headless” argument

由 ☆樱花仙子☆ 提交于 2019-12-06 12:37:53
I have been playing around with Selenium + Chromedriver and I noticed I get different results based on if headless is enabled or disabled. After some investigation I found out that "headless" does not include the Accept-Language header. Is there anyway to manually add this in the headers? DrStrangelove That's what Google chrome does. One way around it would be to use a proxy and modify the headers for you. Or you can use the Firefox driver as that driver does not send different headers when using the headless option. Ideally, using and not using the --headless option shouldn't have any major

How to access a site via a headless driver without being denied permission

问题 I am trying to retrieve the html code of a site using a headless chrome driver. However I get a "permission denied" message. If I use a "regular" driver it all works fine.

Headless chrome with python suspends when trying to download a file

由 无人久伴 提交于 2019-12-05 03:53:59
I'm using Python, Jupyter, Selenium webdriver and headless chrome (with Canary) on Mac. I wrote a script that scrapes a very old website, In order to download a file from that website I need to click on several buttons which eventually lead me to a button that once clicked it downloads a CSV file The problem is that when headless chrome tries to download the target file it suspends and does nothing (i.e. doesn't download the required file) even though the script finished running (and yes I did close it at the end of the script) I tried: Downloading other files (from different websites) and
