问题1：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

解决办法：

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

问题2：”请停用以开发者模式运行的扩展程序” 的解决办法

-解决办法，复制这段到 DevWarningPatch.bat 到任意位置，退出chrome，右键管理员运行即可。：
