我试图下载页面的HTML(在本例中是http://www.google.com
),但是我返回了一个错误。下面是我的交互式提示会话:

我最好的猜测是我的网络防火墙正在阻止连接(除80个端口外的大多数/所有端口都被阻止)。不过,我不明白为什么;Python不是在端口80上连接的吗?有人知道发生了什么吗?
urllib从Internet Explorer获取代理设置,通常位于
Tools->Internet Options->Connections->Lan Settings
如果您有代理,请确保它在IE或set it when using urllib中是正确的。如果不使用代理进行浏览,请确保IE中的代理设置为空。
几个小时后,我一直在努力解决这个问题,直到我意识到我曾经安装的第三方应用程序改变了IE中的设置,而我在没有代理的Firefox中愉快地冲浪。
另一个解决方案在the this link中,它显示了如何强制urllib忽略IE的代理设置
错误来自操作系统级别,与Python无关。任何编程语言都一样。
请与您的网络管理部门联系以了解问题所在,除非您可以自己解决防火墙问题。如果需要HTTP代理,那么可以为urllib配置一个。
