How do I use Python's httplib to send a POST to a URL, with a dictionary of parameters?

I just want a function that can take 2 parameters:

• the URL to POST to
• a dictionary of parameters

How can this be done with httplib? thanks.

From the Python documentation:

>>> import httplib, urllib
>>> params = urllib.urlencode({'spam': 1, 'eggs': 2, 'bacon': 0})
>>> headers = {"Content-type": "application/x-www-form-urlencoded",
...            "Accept": "text/plain"}
>>> conn = httplib.HTTPConnection("musi-cal.mojam.com:80")
>>> conn.request("POST", "/cgi-bin/query", params, headers)
>>> response = conn.getresponse()
>>> print response.status, response.reason
200 OK
>>> data = response.read()
>>> conn.close()
