chromedriver 使用待认证的动态代理--以阿布云为例（

• 以下为我在阿布云上提交的代码示例
  代码中打包一个json和一段JavaScript为zip压缩包
  然后通过 option.add_extension 命令安装至chrome 通过插件实现动态代理

from selenium import webdriver

proxyHost = "http-pro.abuyun.com"
proxyPort = "9010"

proxyPass = "0123456789012345"

装插件后无法直接使用无界面模式运行，需要通过虚拟现实技术间接实现，详情参考: chromedriver使用插件后如何在无界面headless环境下运行
