[ckan-dev] intercepting http request info

Fri Apr 5 17:22:07 UTC 2013

Hi George,

It's not specific to CKAN or Drupal, but it might be good to see how
Facebook implemented this.

When you create a FB Canvas app, your application runs in an iframe inside
FB. The first time the user open it, she gets a signed_request POST
parameter with the user_id and other info (
https://developers.facebook.com/docs/howtos/login/signed-request/). Then
the idea is that you would save this in your user table, to link the local
users with FB's.

It's kinda simple to implement. Might be good to think about a similar way
to do the same to link CKAN and Drupal.

Cheers,
Vítor Baptista.
