尝试在python中使用HTTP POST请求进行POST

Question

I am trying to post two parameters using HTTP POST-request to http://foo.bar.com/submit.jsp .

This works.

conn = httplib.HTTPConnection("www.bar.com")
conn.request("POST", "",parameters)

But this does not, could someone explain to me why it does not and how the correct way is?

conn = httplib.HTTPConnection("www.foo.bar.com")
conn.request("POST", "/submit.jsp", parameters)

I am getting this error

File "example.py", line 68, in <module>
    conn.request("POST", "/submit.jsp", parameters)
  File "/usr/lib/python2.7/httplib.py", line 958, in request
    self._send_request(method, url, body, headers)
  File "/usr/lib/python2.7/httplib.py", line 992, in _send_request
    self.endheaders(body)
  File "/usr/lib/python2.7/httplib.py", line 954, in endheaders
    self._send_output(message_body)
  File "/usr/lib/python2.7/httplib.py", line 814, in _send_output
    self.send(msg)
  File "/usr/lib/python2.7/httplib.py", line 776, in send
    self.connect()
  File "/usr/lib/python2.7/httplib.py", line 757, in connect
    self.timeout, self.source_address)
  File "/usr/lib/python2.7/socket.py", line 553, in create_connection
    for res in getaddrinfo(host, port, 0, SOCK_STREAM):
socket.gaierror: [Errno -2] Name or service not known

Thanks in advance

Answer 1

Whatever hostname you are really using in place of www.foo.bar.com can not be resolved to an IP address. Note that your first example used www.bar.com , not www.foo.bar.com . While these are only examples, the second hostname that you are using is bad.

The path /submit.jsp is not the problem here, if that is what you are actually trying to test?

Answer 2

This error means that python cannot reach the HTTP server you defined in the function, You could have a unneeded "HTTP://", A typo'd url, if you're using IPV6 it could be the form of your address or other network issues.
