Running selenium behind a proxy server
提问by Aryabhatt
I have been using selenium for automatic browser simulations and web scraping in python and it has worked well for me. But now, I have to run it behind a proxy server. So now selenium open up the window but could not open the requested page because of proxy settings not set on the opened browser. Current code is as follows (sample):
我一直在使用 selenium 在 python 中进行自动浏览器模拟和网络抓取，它对我来说效果很好。但是现在，我必须在代理服务器后面运行它。所以现在 selenium 打开窗口但无法打开请求的页面，因为在打开的浏览器上没有设置代理设置。当前代码如下（样例）：
from selenium import webdriver
sel = webdriver.Firefox()
sel.get('http://www.google.com')
sel.title
sel.quit()
How do I change the above code to work with proxy server now as well?
我现在如何更改上述代码以与代理服务器一起使用？

You need to set desired capabilities or browser profile, like this:
您需要设置所需的功能或浏览器配置文件，如下所示：
profile = webdriver.FirefoxProfile()
profile.set_preference("network.proxy.type", 1)
profile.set_preference("network.proxy.http", "proxy.server.address")
profile.set_preference("network.proxy.http_port", "port_number")
profile.update_preferences()
driver = webdriver.Firefox(firefox_profile=profile)

The official Selenium documentation (http://docs.seleniumhq.org/docs/04_webdriver_advanced.jsp#using-a-proxy) provides clear and helpful guidelines about using a proxy. For Firefox (which is the browser of choice in your sample code) you should do the following:
Selenium 官方文档 ( http://docs.seleniumhq.org/docs/04_webdriver_advanced.jsp#using-a-proxy) 提供了有关使用代理的清晰而有用的指南。对于 Firefox（示例代码中选择的浏览器），您应该执行以下操作：
from selenium import webdriver
from selenium.webdriver.common.proxy import *
myProxy = "host:8080"
proxy = Proxy({
'proxyType': ProxyType.MANUAL,
'httpProxy': myProxy,
'ftpProxy': myProxy,
'sslProxy': myProxy,
'noProxy': '' # set this value as desired
})
driver = webdriver.Firefox(proxy=proxy)

This will do the job:
这将完成这项工作：
import selenium
from selenium.webdriver.common.proxy import *
proxyHost = "my.proxy.host or IP"
proxyPort = "55555"
fp = webdriver.FirefoxProfile()
fp.set_preference("network.proxy.type", 1)
#fp.set_preference("network.proxy.http", proxyHost) #HTTP PROXY
#fp.set_preference("network.proxy.http_port", int(proxyPort))
#fp.set_preference("network.proxy.ssl", proxyHost) #SSL PROXY
#fp.set_preference("network.proxy.ssl_port", int(proxyPort))
fp.set_preference('network.proxy.socks', proxyHost) #SOCKS PROXY
fp.set_preference('network.proxy.socks_port', int(proxyPort))
fp.update_preferences()
driver = webdriver.Firefox(firefox_profile=fp)
driver.get("http://www.whatismyip.com/")

def install_proxy(PROXY_HOST,PROXY_PORT):
fp = webdriver.FirefoxProfile()
print PROXY_PORT
print PROXY_HOST
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))
fp.set_preference("network.proxy.https",PROXY_HOST)
fp.set_preference("network.proxy.https_port",int(PROXY_PORT))
fp.set_preference("network.proxy.ssl",PROXY_HOST)
fp.set_preference("network.proxy.ssl_port",int(PROXY_PORT))
fp.set_preference("network.proxy.ftp",PROXY_HOST)
fp.set_preference("network.proxy.ftp_port",int(PROXY_PORT))
fp.set_preference("network.proxy.socks",PROXY_HOST)
fp.set_preference("network.proxy.socks_port",int(PROXY_PORT))
fp.set_preference("general.useragent.override","Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_3) AppleWebKit/537.75.14 (KHTML, like Gecko) Version/7.0.3 Safari/7046A194A")
fp.update_preferences()
return webdriver.Firefox(firefox_profile=fp)
