20_代理方式打开浏览器

无需代理

        # 无代理情况
        cls.driver = selenium.webdriver.Chrome()
        cls.driver.get("http://daido.sitetest1.com/")
        cls.driver.maximize_window()

需要代理，代理没有密码

        # 有代理，代理无密码
        # chromeOptions = webdriver.ChromeOptions()  # 设置代理
        # chromeOptions.add_argument("--proxy-server=http://192.168.116.141:808")
        # # cls.driver=webdriver.Chrome(chrome_options=chromeOptions)
        # cls.driver = webdriver.Chrome()  #不适用代理
        # cls.driver.maximize_window()
        # cls.driver.get("http://platform1.comitbpm.com/")  # rakuten

有代理，代理需要密码

   # 有代理的情况，且代理需要密码
    # proxy = 'test001:123qwe.com@172.16.0.5:3128'
    # cls.driver = Function.Getproxy.get_driver(proxy)
    # cls.driver.get("http://platform1.comitbpm.com/")
    # cls.driver.implicitly_wait(10)  # 隐式等待10秒

此时需要使用单独的driver，默认的不可以

下面是配置图，和code
