from selenium.webdriver.chrome.options import Options
import zipfile

port = 808
username = 'foo'
password = 'bar'

manifest_json = """

""" % {'ip': ip, 'port': port, 'username': username, 'password': password}
# 会在本地创建一个manifest.json配置文件和background.js脚本来设置认证代理
# 运行代码后会生成proxy_auth_plugin.zip文件来保存当前配置
