Re: [OpenSocial] Re: Failed to retrieve gadget content...

[Chris Chabot <ch...@xs4all.nl>]

Hey Tuhin, glad to hear your making some progress!

I think the encoding of the token was changed a bit some 5 weeks ago,  
when we were working on the RESTful API support. Previously the token  
was always posted, but with the REST service it's often parsed as a  
$_GET, so the encoding had to be updated.

The simplest way to make sure 'it just works', is probably to copy the  
token code from partuza's gadget creating logic:
http://code.google.com/p/partuza/source/browse/trunk/Application/Views/gadget/gadget.php?r=111

A quick look there will show that it now does a:
	"st=".urlencode(base64_encode($securityToken->toSerialForm()))

to append the token to the URL.

Ps, the best place for shindig development & usage questions is the  
shindig mailing list: shindig-dev@incubator.apache.org there's a lot  
more people there with knowledge of how php shindig works then on the  
generic 'container' list. See http://incubator.apache.org/shindig/#tab-support 
  for how to sign up there.

Good luck!

	-- Chris
