通过将Selenium Webdriver与Python结合使用在Headless chrome浏览器上运行脚本时发生超时错误 [英] Timeout Error occurred When run a script on Headless chrome browser by using Selenium Webdriver with Python

问题描述

当我运行python脚本以测试 Headless Chrome Broswer(Webdriver + Selenium )上的网站时，我们经常会遇到超时错误，我发现该问题是通过.click()或.send_keys()方法.谁能知道这是什么问题?有时工作正常，但有时会出现超时错误.请给出相同的解决方案

When I am running python scripts to test a website on Headless Chrome Broswer (Webdriver + Selenium), we often get a timeout error, I found out the problem occurred when script interacted with browser by .click() or .send_keys() methods. Can anyone know what the kind of problem it is? Sometimes it is working fine but sometimes I have got timeout error. Please give a solution for the same

推荐答案

我遇到了类似的问题，普通的Chrome驱动程序工作正常，但无头Chrome总是超时.

I was having a similar problem, normal Chrome driver worked fine, but headless chrome always timed out.

我发现对于自适应网页，您需要设置窗口大小:

I found out that for responsive web pages, you need to set the window size:

driver.set_window_size(1200, 600)

在驱动程序本身初始化后添加此行之后，它起作用了.

It worked after adding this line just after initialization of the driver itself.

我希望这会有所帮助！
