Question

I’ve pretty new to using FQL in any form, sorry if this is a simple question, but I can’t seem to get around it.

I have this code that’s attempting to get a Friend list:

var query = FB.Data.query('SELECT '+response.id+', '+response.name+' FROM friendlist from user where uid=' + response.id);

But the response I keep getting back is

“An active access token must be used to query information about the current user.”

When I pull back the response object from the /me query I see all my information such as location, name, work, etc. But I don’t see any access token

The code starts like this:

window.fbAsyncInit = function() {
            FB.init({appId: '12...0', status: true, cookie: true, xfbml: true});

            /* All the events registered */
            FB.Event.subscribe('auth.login', function(response) {
                // do something with response
                login();
            });
            FB.Event.subscribe('auth.logout', function(response) {
                // do something with response
                logout();
            });

            FB.getLoginStatus(function(response) {
                if (response.session) {
                    // logged in and connected user, someone you know
                    login();
                }
            });

How do I acquire an access token and provide along with the FQL query?

Thanks for any advice ahead of time!

Answer 1

The access token that you have to use in order to do all types of requests to the Graph API (including FQL queries) is given by facebook after the user has succesfuly logged in.

If you are using firebug do a console.log(response) after the user logs in to see the object that you receive.

 FB.Event.subscribe('auth.login', function(response) {
     console.log(response);   
     // do something with response
     login();
 });

It should contain 3 properties: perms, session and status. perms contains a list with permissions granted by the user, the status it’s the status of the current user. What matters to you is the session property. This one it’s also an object that among others has a access_token property (string) which you can use to do requests to API.

So, your query may look like this:

var query = FB.Data.query('SELECT '+response.id+', '+response.name+' FROM friendlist from user where uid=' + response.id + '&access_token='+response.session.access_token);

If you want to get the session in a better way, use FB.getSession, which returns the current session. More info here.

Good luck !
