Selenium WebDriverException with headless chrome

Question

我制作了一个python脚本，它可以抓取信息并点击几个按钮，它在chrome网络驱动程序上运行得很好，但当我尝试将其输入为无头时，它在几秒钟内什么都不做，然后出现错误。我的代码在下面。

options = Options()
options.headless = True
options.add_argument("user-data-dir=selenium")
browser = webdriver.Chrome(executable_path=r'C:UsersREDACTEDDesktopREDACTEDbrowserchromedriver.exe', options=options)
browser.get('https://REDACTED')

这是错误

Answer 1

当我使用硒和铬时，对我有效的是：

您可以尝试options.add_argument('--headless')，因为您的方法会出现错误(仅适用于chrome，不适用于firefox(

您可以尝试的另一件事是从executable_path中删除.exe。当我添加.exe时，我会得到与您相同的错误。
