How to handle callback urls

[lankesh87]

Hi,

I am trying to handle a callback url. Following is the code in my
urls.py file:

--------------------------------------------------------------------------------------
urls.py:-
--------------------------------------------------------------------------------------

from django.conf.urls.defaults import *

# Uncomment the next two lines to enable the admin:
#from django.contrib import admin
#admin.autodiscover()

urlpatterns = patterns('',
# Example:
(r'^tweet/', 'tweety.views.twitter_tweet'),

#in the next line i wish to handle the callback url:-
(r'^return/(?P<qqq>\)', 'tweety.views.twitter_return'),

# Uncomment the admin/doc line below to enable admin
documentation:
#(r'^admin/doc/', include('django.contrib.admindocs.urls')),

# Uncomment the next line to enable the admin:
#(r'^admin/', include(admin.site.urls)),
)


--------------------------------------------------------------------------------

In my twitter app i have given callback url as:

"http://127.0.0.1:8001/return/"

but the actual url has some added parameters. Something like this:

"http://127.0.0.1/return/?
oauth_token=SOME_VALUE&oauth_verifier=SOME_VALUE"

SOME_VALUE is alphanumeric.

Now all I need is how to handle this url in Regular Expression

Thanks in advance.

As the documentation[1] clearly explains, GET parameters (those after the ?) are not matched in the URLconf. Get them in the view, with request.GET.

I am trying to access the session variable named

but it gives keyerror...


This is the code in my views.py file:

With this URL you have two GET parameters.

You can reach them via request.GET['oauth_token'] and request.GET['oauth_verifier'].

An easy way to find out what comes with the request.GET object is to print it at the begin of your view:

import pprint
pprint.pprint request.GET

good luck,
