selenium配置带用户名和密码的隧道代理

无账号密码使用 Selenium 实现 HTTP 代理

import time

from selenium import webdriver
from selenium.webdriver.chrome.service import Service

# 设置代理IP
proxy_ip = "127.0.0.1"
proxy_port = "1080"

# 配置浏览器选项
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--proxy-server=http://{}:{}'.format(proxy_ip, proxy_port))

# 启动浏览器
chrome_service = Service("./chromedriver.exe")
driver = webdriver.Chrome(service=chrome_service, options=chrome_options)

# 访问百度官网
driver.get('https://www.baidu.com')

# 在这里执行你的操作，比如查找元素、输入搜索关键词等
time.sleep(30)

# 关闭浏览器
driver.quit()

selenium添加代理（有账号密码）

Selenium-Chrome-HTTP-Private-Proxy HTTP 代理解决方案

• 默认情况下，Chrome的--proxy-server="http://ip:port"参数不支持设置用户名和密码认证。因此"Selenium + Chrome Driver"无法使用HTTP Basic Authentication的HTTP代理。一种变通的方式就是采用IP地址认证，但在国内网络环境下，大多数用户都采用ADSL形式网络接入，IP是变化的，也无法采用IP地址绑定认证。因此迫切需要找到一种让Chrome自动实现HTTP代理用户名密码认证的方案。
• Stackoverflow上有人分享了一种利用Chrome插件实现自动代理用户密码认证的方案非常不错，详细地址：http://stackoverflow.com/questions/9888323/how-to-override-basic-authentication-in-selenium2-with-java-using-chrome-driver
• 鲲之鹏的技术人员在此思路的基础上用Python实现了自动化的Chrome插件创建过程，即根据指定的代理“username:password@ip:port”自动创建一个Chrome代理插件，然后可以在"Selenium + Chrome Driver"中通过安装该插件实现代理配置功能（插件地址：https://github.com/RobinDev/Selenium-Chrome-HTTP-Private-Proxy）

如何实现

• 1、访问插件地址下载插件，放在项目目录中供使用
• 2、编写代码
