Hi,
The DataRequest object (req) is used for batch operations. In the
above code, you are adding 2 requests, one for fetching the viewer
details, and the other for fetching the viewer's friends. You add a
key to each of the requests ("viewer" and "viewerFriends"), so you can
retrieve the data later from the response using these keys. A more
complete example would be as follows. Note how the data is retrieved
in the callback, using the key name and data.get().
var req = opensocial.newDataRequest();
req.add(req.newFetchPersonRequest("VIEWER"), "viewer");
req.add(req.newFetchPeopleRequest("VIEWER_FRIENDS"), "viewerfriends");
req.send(onGotViewer);
function onGotViewer(data)
{
var viewer = data.get("viewer").getData();
var viewerfriends = data.get("viewerfriends").getData().asArray();
...
}
Let me know if you need more help.
Thanks,
Anash
