环境: windows 7 + python 3.5.2 + selenium 3.4.2 + chrome driver 2.29 + chrome 58.0.3029....

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'

  manifest_json = """
  {
    "version": "1.0.0",
    "manifest_version": 2,

    ],
    "background": {
      "scripts": ["background.js"]
    },
    "minimum_chrome_version":"22.0.0"
  }

  background_js = string.template(
  """
  var config = {
      mode: "fixed_servers",

       singleproxy: {

        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_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:
