代理方式

以下方式均实机测试过。

方式一

无需验证，只需填写代理IP和端口号

from selenium import webdriver

chrome_driver ="F:\PycharmProjects\chromedriver_win32\chromedriver.exe"

option = webdriver.ChromeOptions()
option.add_argument('--proxy-server=http://代理IP:端口号')
driver = webdriver.Chrome(executable_path=chrome_driver, chrome_options=option)
driver.get("https://proxy.mimvp.com/ip.php/")
driver.close()

方式二

通过生成插件并加载通过代理验证，需要填写代理IP、端口号、验证账号和密码，该方式缺点是不支持后台静默运行（headless）

from selenium import webdriver
import zipfile
import string

chrome_driver ="F:\PycharmProjects\chromedriver_win32\chromedriver.exe"# 生成代理插件，返回插件路径defcreate_proxy_auth_extension(proxy_host, proxy_port, proxy_username, proxy_password, scheme='http',
