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

Selenium官方給的Firefox代理配置方式并不起效，也沒看到合適的配置方式，對于Chrome Selenium官方沒有告知如何配置，但以下兩種方式是有效的：

1. 連接無用戶名密碼認證的代理

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

2. 有用戶名和密碼的連接

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'  manifest_json = """  {    "version": "1.0.0",    "manifest_version": 2,    "name": "Chrome Proxy",    "permissions": [      "proxy",      "tabs",      "unlimitedStorage",      "storage",      "<all_urls>",      "webRequest",      "webRequestBlocking"    ],    "background": {      "scripts": ["background.js"]    },    "minimum_chrome_version":"22.0.0"  }  """  background_js = string.Template(  """  var config = {      mode: "fixed_servers",      rules: {       singleProxy: {        scheme: "${scheme}",        host: "${host}",        port: parseInt(${port})       },       bypassList: ["foobar.com"]      }     };  chrome.proxy.settings.set({value: config, scope: "regular"}, function() {});  function callbackFn(details) {    return {      authCredentials: {        username: "${username}",        password: "${password}"      }    };  }  chrome.webRequest.onAuthRequired.addListener(        callbackFn,        {urls: ["<all_urls>"]},        ['blocking']  );  """  ).substitute(    host=proxy_host,    port=proxy_port,    username=proxy_username,    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_pathproxyauth_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/)

以上直接通過python代碼生成chrome所需的zip插件文件，IP端口用戶名密碼寫上自己的，原文出處：
