问题 I want to use proxy on chromedp, but proxy not seems to be working, tried chromedp.ProxyServer ctx, cancel := chromedp.NewContext(context.Background()) defer cancel() chromedp.ProxyServer("http://username:password@proxyserver.com:31280") chromedp.Run(ctx, chromedp.Navigate("http://wtfismyip.com"), chromedp.Sleep(3*time.Second), chromedp.ActionFunc(func(ctxt context.Context) error { _, _, contentRect, err := page.GetLayoutMetrics().Do(ctxt) v := page.Viewport{ X: contentRect.X, Y: contentRect

问题 I'm trying safely handle the behavior of a page which uses an in-browser event on a select element to trigger a page reload (POST). The URL is the same but the page reloads with the same HTML and the only difference is the sort order of content in a table. I tried several methods but somehow none are reliable, how can I achieve something like this: try { await page.select('select[name=sort]', 'size'); await page.waitForNextPageReload(); await page.waitForSelector('select[name=sort]'); } catch

问题 Having used this page as a reference: http://executeautomation.com/blog/running-chrome-in-headless-mode-with-selenium-c/ I have tried to get Chrome working in headless mode (with a view to running under SpecFlow/xUnit). This has failed spectacularly and I would like to know if anyone has a solution/fix. I'm running VS 2015 on Windows 7 with a .NET 4.7 console application and Google Chrome Version 65.0.3325.162 (Official Build) (64-bit)... Here's my packages.config: <?xml version="1.0"

问题 I am currently using phantomjs to generate screenshots of web pages. Due to various issues including web fonts, and video tag support, I would like to try switching to headless chrome. Has anyone had success running headless chrome in an azure web app? I cannot find a .net api, and assume I need to run node.js with puppeteer If I want a javascript api similar to phantomjs. 回答1: Right now most of the big libraries are made for NodeJS. It's possible to run Chrome headless without it, but you'll

问题 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? 回答1: 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

问题 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
