使用python通过selenium模拟打开chrome窗口报错 出现 "您使用的是不受支持的命令行标记:--ignore-certificate-errors

#在程序前加上这段代码
from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_experimental_option("excludeSwitches",["ignore-certificate-errors"])
driver = webdriver.Chrome(chrome_options=options)

Leon's comment leads to the correct information that compound class names are no longer supported. What you could do instead is try using css selectors. In your case, the following line of code should help you get the element you want :

el3 = driver.find_element_by_css_selector(".action-btn.cancel.alert-display")

It finds the element with all three classes (action-btn, cancel and alert-display) in the class attribute. Do note that the order of the classes do not matter here and any of the classes may appear anywhere in the attribute. As long as the element has all three classes, it will be selected. If you want the order of the classes to be fixed, you can use the following xpath :

el3 = driver.find_element_by_xpath("//*[@class='action-btn cancel alert-display']") 

你好,你可以在chrome浏览器地址栏输入“chrome://extensions/”,打开chrome浏览器设置,点击“将chrome浏览器设置为默认浏览器”。
