运行结果:
PS：经测试，在无头模式下 验证代理使用失败，报错信息如下:
failed to wait for extension background page to load: chrome-extension://oonccdcfgindlahlpdgfkafbecgknmkg/_generated_background_page.html
from unknown error: page could not be found: chrome-extension://oonccdcfgindlahlpdgfkafbecgknmkg/_generated_background_page.html
不支持加载插件之类的报错信息,不知道是代理 还是 chromedriver的问题,google了很久 没有找到解决方案
