Question

我需要从Javascript SDK的方法中获取。我的标识法

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

        } else {
            // user is logged in, but did not grant any permissions
            alert("No Permission..");
        }
    } else {
        // user is not logged in
        alert("Please login to facebook");
    }
}, {perms: read_stream,publish_stream,offline_access });

Is there any way to get access token? I am able to get the access token using PHP.

Answer 1

您可使用<条码>F.B.getAuthResponse(出入<<>>代码>):

FB.login(function(response) {
   if (response.authResponse) {
     var access_token =   FB.getAuthResponse()[ accessToken ];
     console.log( Access Token =  + access_token);
     FB.api( /me , function(response) {
     console.log( Good to see you,   + response.name +  . );
     });
   } else {
     console.log( User cancelled login or did not fully authorize. );
   }
 }, {scope:   });

Edit: Updated to use Oauth 2.0, required since December 2011. Now uses FB.getAuthResponse(); If you are using a browser that does not have a console, (I m talking to you, Internet Explorer) be sure to comment out the console.log lines or use a log-failsafe script such as:

if (typeof(console) == "undefined") { console = {}; } 
if (typeof(console.log) == "undefined") { console.log = function() { return 0; } }

Answer 2

response.session.access_token doesn t work in my code. But this works: response.authResponse.accessToken

     FB.login(function(response) { alert(response.authResponse.accessToken);
     }, {perms: read_stream,publish_stream,offline_access });

www.un.org/Depts/DGACM/index_spanish.htm 如果你已经连接了,那么在javascript console,就简单地照样:

FB.getAuthResponse()[ accessToken ]

Answer 4

{
    status:  connected ,
    authResponse: {
        accessToken:  ... ,
        expiresIn: ... ,
        signedRequest: ... ,
        userID: ... 
    }
}


FB.login(function(response) {
    if (response.authResponse) {
        // The person logged into your app
    } else {
        // The person cancelled the login dialog
    }
});

Answer 5

response.session doesn t work anymore because response.authResponse is the new way to access the response content after the oauth migration.
Check this for details: SDKs & Tools › JavaScript SDK › FB.login
