添加无认证代理，以参数形式添加
chromeOptions = webdriver.ChromeOptions()
chromeOptions.add_argument('--proxy-server=http://ip:port')
driver = webdriver.Chrome(chrome_options=chromeOptions)
添加认证代理，以插件的形式添加
1、新建扩展文件夹 Chrome-proxy-helper添加两个文件
Chrome-proxy-helper/
background.js
manifest.json
内容如下
（1）background.js
var config = {
mode: "fixed_servers",
rules: {
singleProxy: {
scheme: "http",
host: "%proxy_host",
port: parseInt(%proxy_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']
);
（2）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"
}
2、动态生成插件并使用
# -*- coding: utf-8 -*-
import os
import re
import time
import zipfile
from selenium import webdriver
# Chrome代理模板插件(https://github.com/RobinDev/Selenium-Chrome-HTTP-Private-Proxy)目录
CHROME_PROXY_HELPER_DIR = 'Chrome-proxy-helper'
# 存储自定义Chrome代理扩展文件的目录
CUSTOM_CHROME_PROXY_EXTENSIONS_DIR = 'chrome-proxy-extensions'
def get_chrome_proxy_extension(proxy):
"""
获取一个Chrome代理扩展,里面配置有指定的代理(带用户名密码认证)
proxy - 指定的代理,格式: username:password@ip:port
"""
m = re.compile('([^:]+):([^\@]+)\@([\d\.]+):(\d+)').search(proxy)
if m:
# 提取代理的各项参数
username = m.groups()[0]
password = m.groups()[1]
ip = m.groups()[2]
port = m.groups()[3]
# 创建一个定制Chrome代理扩展(zip文件)
if not os.path.exists(CUSTOM_CHROME_PROXY_EXTENSIONS_DIR):
os.mkdir(CUSTOM_CHROME_PROXY_EXTENSIONS_DIR)
extension_file_path = os.path.join(CUSTOM_CHROME_PROXY_EXTENSIONS_DIR, '{}.zip'.format(proxy.replace(':', '_')))
if not os.path.exists(extension_file_path):
# 扩展文件不存在，创建
zf = zipfile.ZipFile(extension_file_path, mode='w')
zf.write(os.path.join(CHROME_PROXY_HELPER_DIR, 'manifest.json'), 'manifest.json')
# 替换模板中的代理参数
background_content = open(os.path.join(CHROME_PROXY_HELPER_DIR, 'background.js')).read()
background_content = background_content.replace('%proxy_host', ip)
background_content = background_content.replace('%proxy_port', port)
background_content = background_content.replace('%username', username)
background_content = background_content.replace('%password', password)
zf.writestr('background.js', background_content)
zf.close()
return extension_file_path
else:
raise Exception('Invalid proxy format. Should be username:password@ip:port')
if __name__ == '__main__':
# 测试
options = webdriver.ChromeOptions()
# 添加一个自定义的代理插件（配置特定的代理，含用户名密码认证）
options.add_extension(get_chrome_proxy_extension(proxy="username:password@ip:port"))
driver = webdriver.Chrome(options=options)
# 访问一个IP回显网站，查看代理配置是否生效了
driver.get('http://httpbin.org/ip')
print(driver.page_source)
time.sleep(60)
driver.close()
driver.quit()
