Handling responses of os:HttpRequest 

Hi,

we are currently migrating our PHP shindig deployment to the current trunk. While testing the os:HttpRequest Tag I came around a significant difference between the PHP Shindig and the tutorial in the OpenSocial wiki.

http://wiki.opensocial.org/index.php?title=OpenSocial_Templates_Developer%27s_Guide#Fetching_data_from_a_URL

says that a Json construct like this 

{
  friends : [
    {
      name: 'David',
      interests: 'Cooking',
    },
    {
      name: 'Charles',
      interests: 'Hiking',
    },
    {
      name: 'Mary',
      interests: 'Football',
    },
  ]
}

can be fetched with

<os:HttpRequest key="friends" href="http://myfriendsserver.com"/>
and viewed with

<li repeat="${friends}">
       <span>Name: ${Cur.name} Hobby: ${Cur.interests}</span>
     </li>

The current PHP implementation handles this a bit differently:

<li repeat="${friends.result.content.friends}">
        <span>Name: ${Cur.name} Hobby: ${Cur.interests}</span>
</li>

Here the first "friends" is the key of the os:HttpRequest, "result" and "content" come from the php implementation and the second "friends" is from the json object.

Which is the right implementation and how is it done in the Java Shindig?

I looked into the spec http://www.opensocial.org/Technical-Resources/opensocial-spec-v09/OpenSocial-Data-Pipelining.html#HttpRequest and it seems that the PHP way is correct instead of the tutorial. Should I change the tutorial or submit a patch to the PHP Shindig?

Best regards

Bastian

Hey,

I just wanted to pop this up. Any comments? If not, than I'd propose that I change the tutorial in the wiki according to the PHP implementation and Spec example.

Best regards
