如何通过代理使用tweepy流媒体API？

Question

我知道有一个补丁可以让REST API通过代理使用，而且对我来说是有效的。但是，Streaming API使用的是HTTP连接，而urllib和urllib2（据我所知）无法模拟这种连接。有没有什么解决办法呢？

我尝试过使用带端口的代理，但没有成功。在streaming.py文件的第153行。

    if self.scheme == "http":
                conn = httplib.HTTPConnection(self.api.proxy_host,self.api.proxy_port, timeout=self.timeout)
            else:
                conn = httplib.HTTPSConnection(self.api.proxy_host,self.api.proxy_port,timeout=self.timeout)
            self.auth.apply_auth(url, 'POST', self.headers, self.parameters)
            print conn.host
            conn.connect()
            conn.request('POST', self.scheme+'://'+self.host+self.url, self.body, headers=self.headers)
            resp = conn.getresponse()

而且，"self.scheme+'://'+self.host+ self.url"对应的链接是 - https://stream.twitter.com/1.1/statuses/filter.json?delimited=length

我收到的错误是 -

Answer 1

Tweepy 现在不支持使用代理。不过，接下来几天应该会增加对代理的支持。我会在这个回答里更新更多信息。

Answer 2

我终于找到一个GitHub上的补丁，可以通过代理来启用流式API。效果很好！
