Retrieve Facebook users that like a URL / web page via Open Graph

Is there a way to retrieve the list of Facebook users that have clicked the like button on an external website?

• E.g. there is a domain example.com which has been confirmed via Facebook Insights to belong to fbUser1 (using OG meta tags).
• Somewhere on example.com there is a page with multiple XFBL like buttons, each one pointing to a further specific URL on example.com, e.g. example.com/xyz, example.com/abc etc.

What I'd like to get is the list of users that liked example.com/xyz and of those who liked example.com/abc.

My intuitive approach would be to look at graph.facebook.com/123456789/likes (where the number is the ID of the domain taken from FB insights), but this always returns an empty dataset:

{
   "data": [

   ]
}

I've also tried getting an OAuth access token from https://graph.facebook.com/oauth/access_token?type=client_cred&client_id=APPID&client_secret=APPSECRET (where APPID and APPSECRET are taken from a FB application that is marked as owning the domain using OG meta tags), but that makes no difference.

I'd also be interested in a non-OpenGraph (i.e. JS SDK, FQL etc.) solution.

EDIT: Using the following code (according to WideB开发者_开发知识库lade's answer below) still gives me an empty list of likes (the second query never returns):

var objectsQuery = "select id from object_url where url in ('http://example.com/xyz', 'http://example.com/abc', 'http://example.com/123')";
var likesQuery = "select object_id from like where object_id = {0}";

FB.Data.query(objectsQuery).wait(function (objectRows) {
    console.log(objectRows);

    FB.Array.forEach(objectRows, function (objectRow) {
        FB.Data.query(likesQuery, objectRow.object_id).wait(function (likeRows) {
            console.log(likeRows);
        })
    });
});

FQL Should do the trick.

$facebook->api_client->fql_query('SELECT user_id FROM like WHERE object_id="OBJECTID"');

Here is the link.

Some general info about FQL.

FQL is initiated using the JavaScript SDK, in this way.

If you can post some sample code-I can try and give some more specific help.

A note should be made-once you've got the user ID's, you can just query the names and get them in a list.

EDIT: To get the URL of an object you should query this table using fql.

This cannot be done. Facebook does not allow you to query for specific user ID's of people who have liked a certain page. This is because of privacy concerns.
