response.session.access_token is not working during the facebook connect?

JavaScript SDK and OAuth 2.0 Roadmap

Facebook has updated JavaScript SDK and OAuth 2.0 Roadmap

Due to this reason response.session.access_token is not working

So You have make some changes in your Facebook login Function

 

FB.login(function(response) {
                if(response.session) {

                    var access_token = response.session.access_token;

                    FB.api('/me', function(response) {
                    }
                }
}

 

Your code was like this in facebook login function.

 

So edit some code and make this problem solved 

 

FB.login(function(response) {
                    if (response.authResponse) {
                    var accessToken = response.authResponse.accessToken;
                    alert(accessToken);
                    FB.api('/me', function(response) {
                    }
                }
}

So you have to change response.session to response.authResponse

and  access_token to accessToken

Done
