how to post data to particular url?

I want to post some data in the开发者_如何学编程 particular url say http://localhost:8000/postme/. But I have know form yet. So, I want to test it without any form. So, How can I post data to the url without any form? I want to see the response to the web browser.

You can do an Ajax post using jQuery. See this page for the API.

Or for Python, you can use httplib. See this page for the API. Here's an example:

>>> 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()

You can use curl for this:

curl -F "name=jonesy" http://localhost:8080/postme

Or you can use the twill python module (which also has a shell interface):

twill-sh
jonesy$ twill-sh

....the links go on forever, but you get the point. You can use twill in the shell like I did here, or those commands can be called as methods in the twill.commands module in a python script.

Of course, you can leave the twill shell and open the file 'search' (in this example) to see the actual html that went to the browser.
