使用Python的HTTP请求：TypeError:需要整数（get type socket）

Question

我在尝试通过HTTP检索资源时遇到了一个非常奇怪的bug。这似乎发生在任何HTTP客户机上（尝试请求和urllib结果相同）。在

我的项目使用django，我使用tox和标准django命令python manage.py test运行测试。当我运行我的测试套件时，一个单元测试发出一个HTTP请求（例如通过requests.get('http://example.com')），测试失败并出现错误，测试套件继续到最后，并挂起。我必须通过命令行手动终止进程。在

经过一些调查，我在http请求周围放置了一个try / except块，得到了以下stacktrace：

File "/mycomputer/python3.4/site-packages/requests/api.py", line 68, in get
  return request('get', url, **kwargs)
File "/mycomputer/python3.4/site-packages/requests/api.py", line 50, in request
  response = session.request(method=method, url=url, **kwargs)
File "/mycomputer/python3.4/site-packages/requests/sessions.py", line 464, in request
  resp = self.send(prep, **send_kwargs)
File "/mycomputer/python3.4/site-packages/requests/sessions.py", line 576, in send
  r = adapter.send(request, **kwargs)
File "/mycomputer/python3.4/site-packages/requests/adapters.py", line 370, in send
  timeout=timeout
File "/mycomputer/python3.4/site-packages/requests/packages/urllib3/connectionpool.py", line 544, in urlopen
  body=body, headers=headers)
File "/mycomputer/python3.4/site-packages/requests/packages/urllib3/connectionpool.py", line 349, in _make_request
  conn.request(method, url, **httplib_request_kw)
File "/usr/lib/python3.4/http/client.py", line 1065, in request
  self._send_request(method, url, body, headers)
File "/usr/lib/python3.4/http/client.py", line 1103, in _send_request
  self.endheaders(body)
File "/usr/lib/python3.4/http/client.py", line 1061, in endheaders
  self._send_output(message_body)
File "/usr/lib/python3.4/http/client.py", line 906, in _send_output
  self.send(msg)
File "/usr/lib/python3.4/http/client.py", line 841, in send
  self.connect()
File "/mycomputer/python3.4/site-packages/requests/packages/urllib3/connection.py", line 155, in connect
  conn = self._new_conn()
File "/mycomputer/python3.4/site-packages/requests/packages/urllib3/connection.py", line 134, in _new_conn
  (self.host, self.port), self.timeout, **extra_kw)
File "/mycomputer/python3.4/site-packages/requests/packages/urllib3/util/connection.py", line 68, in create_connection
  sock = socket.socket(af, socktype, proto)
File "/usr/lib/python3.4/socket.py", line 123, in __init__
  _socket.socket.__init__(self, family, type, proto, fileno)
TypeError: an integer is required (got type socket)

我真的不明白这里的问题。从命令行运行同样的操作非常完美，因此这可能与我的项目架构有关。另外，在另一台计算机上运行测试套件也会以同样的方式失败。在

有人遇到过类似的问题吗？我能做些什么来追踪这个问题？在

我在某个地方读到django不是一个完整的服务器，当您尝试将其作为一个完整的服务器使用时，可能会导致问题。也许这就是其中之一。在

你试过https://docs.djangoproject.com/en/1.8/topics/testing/advanced/？在

好的，问题是由HTTPretty引起的，这是我用来模仿的第三方包。在
