Selenium chrome配置代理Python版的方法

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

from selenium import webdriverdef create_proxyauth_extension(proxy_host, proxy_port,
               proxy_username, proxy_password,
               scheme='http', plugin_path=None):
 """Proxy Auth Extension

args:
   proxy_host (str): domain or ip address, ie proxy.domain.com
   proxy_port (int): port
   proxy_username (str): auth username
   proxy_password (str): auth password
 kwargs:
   scheme (str): proxy scheme, default http
   plugin_path (str): absolute path of the extension    

return str -> plugin_path
 """
 import string
 import zipfile

if plugin_path is None:
   plugin_path = 'd:/webdriver/vimm_chrome_proxyauth_plugin.zip'

    };

chrome.proxy.settings.set({value: config, scope: "regular"}, function() {});

function callbackFn(details) {
   return {
     authCredentials: {
       username: "${username}",
       password: "${password}"
     }
   };
 }

chrome.webRequest.onAuthRequired.addListener(
       callbackFn,
       {urls: ["<all_urls>"]},
       ['blocking']
 );

 ).substitute(
   host=proxy_host,
   port=proxy_port,

   password=proxy_password,
   scheme=scheme,
 )
 with zipfile.ZipFile(plugin_path, 'w') as zp:
   zp.writestr("manifest.json", manifest_json)
   zp.writestr("background.js", background_js)

return plugin_path

proxyauth_plugin_path = create_proxyauth_extension(
 proxy_host="proxy.crawlera.com",
 proxy_port=8010,
 proxy_username="fea687a8b2d448d5a5925ef1dca2ebe9",
 proxy_password=""

co = webdriver.ChromeOptions()
co.add_argument("--start-maximized")
co.add_extension(proxyauth_plugin_path)

driver = webdriver.Chrome(chrome_options=co)
driver.get(http://www.amazon.com/)

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：
