Question

此代码用于完美运行。我没有改变任何东西，但尝试从代理后面的其他位置使用它，我收到此错误：

IOError: [Errno socket error] [SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:590)

这是失败的地方：

gcontext = ssl.SSLContext(ssl.PROTOCOL_TLSv1)
data = urllib.urlopen("https://itunes.apple.com/us/rss/topfreeapplications/limit=50/genre=" + str(category) + "/json", "download.txt", context = gcontext).read()

我立即认为问题可能来自我正在使用的代理，但不知道如何告诉python也使用该代理。 this thread中的解决方案对我没有帮助（同样的错误）。

这是完整的追溯：

非常感谢你的帮助！
