Question

我制作了一个python脚本，该脚本可抓取信息并单击一些按钮，并且在chrome webdriver上运行良好，但是当我尝试以无头方式输入它时，它在几秒钟内什么也不做，然后给出了错误。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:\Users\REDACTED\Desktop\REDACTED\browser\chromedriver.exe', options=options)
browser.get('https://REDACTED')

这是错误

Answer 1

当我将硒与铬一起使用时，对我有用的是：

您可以尝试options.add_argument('--headless')，因为您的方法会引发错误（仅适用于chrome，不适用Firefox）

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