httplib2 使用代理给出内部服务器错误 500

Question

以下是它抛出的代码和错误。它在没有代理 http = httplib2.Http() 的情况下工作正常。

当我在 Firefox 中尝试相同的 http 代理时，它工作正常。

任何指点都将受到高度赞赏！

用法：

http = httplib2.Http(proxy_info = httplib2.ProxyInfo(socks.PROXY_TYPE_HTTP, '68.48.25.158', 25681))

main_url = 'http://www.mywebsite.com'
response, content = http.request(main_url, 'GET')

错误：

  File "testproxy.py", line 17, in <module>
    response, content = http.request(main_url, 'GET')
  File "/home/kk/bin/pythonlib/httplib2/__init__.py", line 1129, in request
    (response, content) = self._request(conn, authority, uri, request_uri, method, body, headers, redirections, cachekey)
  File "/home/kk/bin/pythonlib/httplib2/__init__.py", line 901, in _request
    (response, content) = self._conn_request(conn, request_uri, method, body, headers)
  File "/home/kk/bin/pythonlib/httplib2/__init__.py", line 862, in _conn_request
    conn.request(method, request_uri, body, headers)
  File "/usr/lib/python2.5/httplib.py", line 866, in request
    self._send_request(method, url, body, headers)
  File "/usr/lib/python2.5/httplib.py", line 889, in _send_request
    self.endheaders()
  File "/usr/lib/python2.5/httplib.py", line 860, in endheaders
    self._send_output()
  File "/usr/lib/python2.5/httplib.py", line 732, in _send_output
    self.send(msg)
  File "/usr/lib/python2.5/httplib.py", line 699, in send
    self.connect()
  File "/home/kk/bin/pythonlib/httplib2/__init__.py", line 740, in connect
    self.sock.connect(sa)
  File "/home/kk/bin/pythonlib/socks.py", line 383, in connect
    self.__negotiatehttp(destpair[0],destpair[1])
  File "/home/kk/bin/pythonlib/socks.py", line 349, in __negotiatehttp
    raise HTTPError((statuscode,statusline[2]))
socks.HTTPError: (500, 'Internal Server Error')

确保代理不透明。我对此不太了解，但显然透明代理使服务器能够看到您正在使用代理，甚至可能访问您的 IP。有些网站肯定会关闭任何看似来自代理的请求（因为担心机器人）。这可能意味着抛出假的内部服务器错误或实际遇到错误。对我来说，使用匿名代理总是可以解决这个问题。既然你说它不需要代理就可以工作，所以我会从那里开始。

SOCKS 客户端库是否已安装并可用于您的代码？仅当安装了 SOCKS 库时，代理支持才起作用。
