Selenium chrome配置代理Python版的方法

2021-04-23 00:20大棚 Python

这篇文章主要介绍了Selenium chrome配置代理Python版的方法,小编觉得挺不错的,现在分享给大家,也给大家做个参考。一起跟随小编过来看看吧

环境: windows 7 + Python 3.5.2 + Selenium 3.4.2 + Chrome Driver 2.29 + Chrome 58.0.3029.110 (64-bit)

Selenium官方给的Firefox代理配置方式并不起效,也没看到合适的配置方式,对于Chrome Selenium官方没有告知如何配置,但以下两种方式是有效的:

1. 连接无用户名密码认证的代理

chromeOptions = webdriver.ChromeOptions()
chromeOptions.add_argument('--proxy-server=http://ip:port')
driver = webdriver.Chrome(chrome_options=chromeOptions)

2. 有用户名和密码的连接

以上直接通过python代码生成chrome所需的zip插件文件,IP端口用户名密码写上自己的,原文出处:
