Question

我尝试使用Python在Selenium中测试样本。我正在使用代理服务器连接到Internet并进行身份验证。当我尝试运行以下代码时：

from selenium import webdriver   

if __name__ == '__main__':

    proxy = "some_IP"
    port = 3128

    fp = webdriver.FirefoxProfile()
    fp.set_preference('network.proxy.ssl_port', int(port))
    fp.set_preference('network.proxy.ssl', proxy)
    fp.set_preference('network.proxy.http_port', int(port))
    fp.set_preference('network.proxy.http', proxy)
    fp.set_preference('network.proxy.ftp', proxy)
    fp.set_preference('network.proxy.ftp_port', int(port))
    fp.set_preference('network.proxy.socks', proxy)
    fp.set_preference('network.proxy.socks_port', int(port))

    fp.set_preference('network.proxy.type', 1)

    browser = webdriver.Firefox(firefox_profile=fp)
    browser.set_page_load_timeout(15)
    browser.get('http://www.google.com')
    print browser.title

Firefox浏览器打开没有任何问题，在其代理配置中一切正常，即使打开身份验证弹出窗口也是如此。如果我对自己进行身份验证，我可以毫无问题地导航。问题是，在此背后我得到以下错误：

我正在使用selenium 2.34和Firefox 17.感谢任何帮助。

Answer 1

在找到这个问题的解决方案4天后，我终于找到了。问题在于浏览器排除，我的意思是任何浏览器中代理配置中的选项卡。您需要在排除的两个地址中放入您拥有的任何浏览器：

localhost和127.0.0.1

这非常重要，因为如果有人因为它试图连接到上面提到的两个地址而导致Selenium的这个原因问题。

使用代理的Firefox中的Selenium配置
