代理背后的PyQt + QtWebkit [英] PyQt + QtWebkit behind a proxy

问题描述

我正在编写一个PyQt（全功能Qt库的Python绑定）应用程序，我的应用程序的一小部分需要一个Web浏览器（提示，OAuth）。所以我开始使用QtWebkit，顺便说一下这很棒。唯一的障碍是我想允许代理后面的用户使用我的应用程序。

I'm writing a PyQt (Python bindings for the all-powerful Qt library) application and a small part of my application needs a web browser (hint, OAuth). So I started using QtWebkit, which is fantastic by the way. The only hitch is I would like to allow users behind a proxy to use my application.

我已经阅读了QtNetwork包中的QNetworkProxy类，并认为应该这样做招。唯一的问题是当我创建和应用代理时，它在HTTP上工作得很好，但是当我传递HTTPS（SSL）URL时，它会给我以下错误：

I have read about the QNetworkProxy class in the QtNetwork package and figure it should do the trick. The only problem is when I create and apply the proxy, it works just fine over HTTP, but when I pass it a HTTPS (SSL) URL, it gives me the following errors:

QSslSocket: cannot call unresolved function SSLv3_client_method
QSslSocket: cannot call unresolved function SSL_CTX_new
QSslSocket: cannot call unresolved function SSL_library_init
QSslSocket: cannot call unresolved function ERR_get_error
QSslSocket: cannot call unresolved function ERR_error_string

注意：当我运行时......

Note: when I run...

QtNetwork.QSslSocket.supportsSsl()

..它返回false。这就是我的问题的证据。

.. it returns false. So that's proof of my problem.

这是我的主要代码（在我创建QApplication之前就已经存在）：

Here's my main code (it's right before my creationg of my QApplication):

proxy = QtNetwork.QNetworkProxy()
proxy.setType(QtNetwork.QNetworkProxy.Socks5Proxy)
proxy.setHostName('localhost');
proxy.setPort(1337)
QtNetwork.QNetworkProxy.setApplicationProxy(proxy);

我从这里但是这个例子是用C ++编写的，而不是Python，所以我不确定我是否正确翻译它。这可能是问题所在。

I got the code from here but the example was written in C++, not Python so I'm not quite sure if I translated it properly. That could be the problem.

编辑：我在SOCKS5和HTTP代理上尝试了它们，它们都抛出相同的错误。

I've tried it over a SOCKS5 and an HTTP proxy and they both throw the same error.

推荐答案

我正在使用Python 2.6和PyQt 4.7.4开发Windows XP（32位）。原因......

I was working on Windows XP (32-bit) with Python 2.6 and PyQt 4.7.4. The reason that...

QtNetwork.QSslSocket.supportsSsl()

返回 false 是因为我没有在系统中安装 OpenSSL二进制文件。

was returning false was because I had not installed OpenSSL binaries to my system.

为了解决这个问题，我去了这里下载二进制文件。在他们正确安装之前，我还必须从Microsoft安装 Visual C ++ 2008 Redistributables 。

To solve the problem I went here to download the binaries. Before they would properly install I had to also get the Visual C++ 2008 Redistributables install from Microsoft.

现在一切正常！
