另外，您可以获得有关连接用户的更多个人信息：

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

希望有所帮助

以下是三种可能的状态：

FB.getLoginStatus(function(response) {
  if (response.status === 'connected') {
    // the user is logged in and connected to your
    // app, and response.authResponse supplies
    // the user’s ID, a valid access token, a signed
    // request, and the time the access token 
    // and signed request each expire
    var uid = response.authResponse.userID;
    var accessToken = response.authResponse.accessToken;
  } else if (response.status === 'not_authorized') {
    // the user is logged in to Facebook, 
    //but not connected to the app
  } else {
    // the user isn't even logged in to Facebook.
  }
});

之后，您设法获得响应会话对象，您可以执行以下操作

            var rec="Name : "+response.name+"";
            rec +="Link: "+response.link+"";
            rec +="Username: "+response.username+"";
            rec +="id: "+response.id+"";
            rec +="Email: "+response.email+"";

            function getPhoto()
            {
            FB.api('/me/picture?type=normal', function(response) {
            var img=response.data.url;
            });
