Facebook API - Detect if session is active OR NOT active
- by Tom Doe
I'm sure I'm simply overlooking something in the Facebook API docs. Basically, after I've loaded the FB Graph, I need to know if the session is active... I cannot simply assume they're logged out and simply re-render if they're logged in once the 'auth.statusChange' event is triggered. I need to know right off the bat.
Below is the code that I've used. Most importantly the FB.getLoginStatus/getAuthResponse/getAccessToken don't work like I'd expect; essentially where it indicates, when invoked, whether they're logged in or out.
(function(d) {
// Create fb-root
var fb_root = document.createElement('div');
fb_root.id = "fb-root";
document.getElementsByTagName('body')[0].appendChild( fb_root );
// Load FB Async
var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "//connect.facebook.net/en_US/all.js";
ref.parentNode.insertBefore(js, ref);
// App config-data
var config = {
appId : XXXX,
cookie: true,
status: true,
frictionlessRequests: true
};
window.fbAsyncInit = function() {
// This won't work.
// I can't assume they're logged out and rely on this to tell me they're logged in.
FB.Event.subscribe('auth.statusChange', function(response) {});
// Init
FB.init(config);
// These do not inidicate if the user is logged out :(
FB.getLoginStatus(function(response) { });
FB.getAuthResponse(function(response) { });
FB.getAccessToken(function(response) { });
};
}(document));
Any help is much appreciated. :)
