Python urllib.request.urlopen() 返回错误 10061？

Question

我正在尝试下载页面的 HTML(在本例中为 http://www.google.com)，但返回错误。这是我的交互式提示 session :

    sock.connect(sa)

ne actively refused it

During handling of the above exception, another exception occurred:

    raise URLError(err)

我最好的猜测是我的网络防火墙阻止了连接(80 以外的大多数/所有端口都被阻止)。不过，我不明白为什么； Python 不连接到端口 80 吗？有谁知道发生了什么事吗？

urllib 从 Internet Explorer 获取代理设置，通常在 Tools->Internet Options->Connections->Lan Settings

如果您有代理，请确保它在 IE 中是正确的，或者 set it when using urllib .如果您不使用代理浏览，请确保IE中的代理设置为空。

我在这个问题上苦苦挣扎了几个小时，直到我意识到我曾经安装的第 3 方应用程序更改了 IE 中的设置，而我在没有代理的情况下在 Firefox 中愉快地冲浪。

另一个解决方案在 the this link 中这显示了如何强制 urllib 忽略 IE 的代理设置
