How to request permissions for facebook app with JavaScript

Question

How can I check the current user login status and ask for permissions for my app? This recently changed and now my app is not working anymore. Thanks for your help!

Answer 1

I always use this setup to handle login status and permissions:

function getPerms() {
    FB.login(function(response) {
        if (response.authResponse) {
            //user has granted permissions
        }
    }, {scope:"email, ..."});
}

function getStatus() {
    FB.getLoginStatus(function(response) {
        if (response.status === "connected") {
            //user has granted permissions
        } else {
            getPerms();
        }
    });
}

You still have to include the all.js and call FB.init(...)

Answer 2

Here is how you can do that:

    FB.init(
    {
        "appId"      : xxxxxxxxxx,
        "status"     : true,
        "cookie"     : true,
        "xfbml"      : true,
        "oauth"      : true
    });

    FB.Event.subscribe('auth.authResponseChange', function(response)
    {
        // need to wait few seconds for fb login status to work in FireFox
        setTimeout('window.location.reload()', 3000);
    });


function fbConnect(){
    FB.getLoginStatus(function(response) {
       if (response.authResponse){
        FB.login(function(response)
        {
            if (response.authResponse) { }
            else
            {
                //console.log('User cancelled login or did not fully authorize.');
            }

        }, {"scope":"email,manage_pages"});
       }
    });
}

You need to call fbConnect() function.

Also make sure that you have these below <body> tag on your page:

<div id="fb-root"></div>
<script src="//connect.facebook.net/en_US/all.js"></script>

Answer 3

You need to provide some code to get better/accurate answers
Most likely you didn't upgrade your code to use OAuth 2.0, see here
Based on the link above, use scope instead of perms
Use response.authResponse instead of response.session
