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'

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

background_js = string.Template(
"""
var config = {

},

}
};

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：
