python httplib timeout to localhost

I have a local server running on port 6868. Technically it's node.js-driven micro-site built with express. It actually has a single '/push' constroller reading some data and writing to console (+ some specific not question-related operatons).

When using curl

h100:~ eugenemirotin$ curl -i http://127.0.0.1:6868/push -d password=pwd
HTTP/1.1 200 OK
X-Powered-By: Express
Connection: keep-alive
Transfer-Encoding: chunked

and node.js wites to console as supposed.

When using python and httplib:

h100:~ eugenemirotin$ python

>>> params = urllib.urlencode(params)

>>> conn = httplib.HTTPConnection('http://127.0.0.1:6868')
>>> conn.request("POST", "/push", params)

The difference in parameters is not essential - the request doesn't even get to node.js server.

Is it httplib bug, or am I doing something wrong?

Remove http:// from the address.

This:

conn = httplib.HTTPConnection('http://127.0.0.1:6868')

Should be:

conn = httplib.HTTPConnection('127.0.0.1:6868')

You can simplify your code a lot:

import urllib, urllib2
params = {'password': 'pwd', 'type': 'msg', 'channel': 'chat', 'client_id': '', 'body': {'text': 'test test'}}    
params = urllib.urlencode(params)
res = urllib2.urlopen('http://127.0.0.1:6868/push/', params)
data = res.read()
res.close()
