Submitting POST data

Okay, so using urllib2 I can send GET data easily to a website like so:

import urllib2

opener = urllib2.build_opener()

page = opener.open( 'http://jammersbase.ath.cx?error=Sent%20some%20get%20data...' ).read()

print "Sent GET data successfully!"

But how do you suppose I sent POST data to a website? I need this so I can login to a website using an automated script.

Will urllib2 store your session as if you're browing directly on the site, or is there some fancy thing I need to do for that? :o

I believe you would use the optional data parameter.

As Dameon said, pass the POST data as the second parameter to urlopen. You can either construct the POST query string by yourself, or use urllib.urlencode to construct the query string from you from a dictionary, e.g

p = urllib.urlopen("http://foo.com/", urllib.urlencode({"foo" : "bar", "bar" : "baz"}))

Depends on the kind of session handling used by the server. If the session ID is added to URLs generated by the server then sure, you won't have to do anything. If the session ID is stored in a cookie, however, you'll need to do a little more work and set up a cookie jar to do so. Python 2.4 includes a built-in module cookielib which lets you do this, but earlier versions of Python can use an external cookie library (with more or less the same usage as cookielib) called ClientCookie.

Oooh! Pretty!! ^^;;

The cookie thing will need some experimentin' with though. Thanks.
