问题描述
我正在使用带有Selenium的Python 2.7中的Firefox WebDriver.我的python程序启动Firefox浏览器，并在运行该程序时访问其他网站.但是，我需要设置具有身份验证的代理，以便当程序访问任何网站时，它将通过代理服务器进行访问.
I am using Firefox WebDriver in Python 2.7 with Selenium. My python program starts Firefox browser and visits different websites when I run the program. But, I need to set the proxy with authentication, so that when program visits any website, it will visit through the proxy server.
关于SO也有一些类似的问题.但是，对于Python的Selenium Firefox WebDriver，没有特定的解决方案.

- Running selenium behind a proxy server
推荐答案
除了运行带有已保存凭据的配置文件的Firefox.您可以加载在chrome://global/content/commonDialog.xul的loginTextbox和password1Textbox(警报窗口)中写入的扩展名.
In addition to running Firefox with a profile which has the credentials saved. You can do it loading an extension that writes in the loginTextbox and password1Textbox of chrome://global/content/commonDialog.xul (the alert window).
已经有一些扩展程序可以完成这项工作.例如:Close Proxy Authentication
There are already some extensions that will do the job. For instance: Close Proxy Authentication
from selenium import webdriver
from base64 import b64encode
proxy = {'host': HOST, 'port': PORT, 'usr': USER, 'pwd': PASSWD}
fp = webdriver.FirefoxProfile()
fp.add_extension('closeproxy.xpi')
fp.set_preference('network.proxy.type', 1)
fp.set_preference('network.proxy.http', proxy['host'])
fp.set_preference('network.proxy.http_port', int(proxy['port']))
# ... ssl, socks, ftp ...
fp.set_preference('network.proxy.no_proxies_on', 'localhost, 127.0.0.1')
credentials = '{usr}:{pwd}'.format(**proxy)
credentials = b64encode(credentials.encode('ascii')).decode('utf-8')
fp.set_preference('extensions.closeproxyauth.authtoken', credentials)
driver = webdriver.Firefox(fp)
