Question

I am using the new FB.ui to create an request to friends on Facebook for my application.

The user is show a panel with their friends and they select the ones they want to send the request.

On the callback I can access the request_id and now I want to get the details for the users that were invited.

If I paste the following code in the browser I can get the user_id of the invited user which is the info I want:

https://graph.facebook.com/138744992885393?access_token=193078857407882|d0048a9beb58a9a247c6b987.0-751640040|zNmBLfZxBBKikoj8RlZiHfKpugM

What I want to be able to do is do the same thing but from my code and then access the information returned.

Here is my code:

    function sendRequests() {
        FB.ui({
            method: 'apprequests',
            message: ' should learn more about this awesome site.',
            data: 'extra data'
        }, function(response) {
            if (response != null && response.request_ids && response.request_ids.length > 0) {
                for (var i = 0; i < response.request_ids.length; i++) {
                    alert("Invited: " + response.request_ids[i]);
// somehow send a request to Facebook api to get the invited user id from the request_id   and save to the database                 
//can save these id's in the database to be used to track the user to the correct page in application.

                }
             top.location.href="http://localhost:3000/";
            } else {
                alert('No invitations sent');
            }
        });
    }

How can I do this?

I am using Rails 3.0.7 Ruby 1.9.2

You can get the facebook user ID as follows:

for (var i = 0; i < req_ids.length; i++) {

        alert("Invited: " + req_ids[i]);
        FB.api('/me/apprequests/?request_ids='+toString(req_ids[i]),
        function(response)
        { alert(response);
            alert(response['data'][0]['from']['id']);
            });

                               }
