Facebook为电子邮件和生日返回undefined

Question

我试图使用Facebook的API,提供first_name,last_name,gender,email,birthday在我的网站上注册.我使用了Graph API并生成了具有必要范围的访问令牌.我尝试在我创建应用程序的个人帐户中正确返回字段,但对于FB测试用户和朋友的帐户,它返回电子邮件和生日为"未定义".在graph.facebook.com中,它显示了朋友帐户的以下错误.

Facebook在doulingo上返回我朋友的同一帐户的电子邮件ID.

我是否错误地设置了权限,还是有任何其他问题？

Answer 1

我的代码的问题是因为没有使用access_token.我用的access_token检索所有,first_name,last_name,gender,birthday,email.

function authUser() {
            FB.login(checkLoginStatus, {scope:'email, user_likes'});
            function checkLoginStatus(response) {
                if(!response || response.status !== 'connected') {
                    alert('User is not authorized');
                    document.getElementById('loginButton').style.display = 'block';
                } else {
                    alert('User is authorized');
                    document.getElementById('loginButton').style.display = 'none';
                    console.log('Access Token: ' + response.authResponse.accessToken);

                    //This has to be in your callback!
                    var uid = response.authResponse.userID;
                    var accessToken = response.authResponse.accessToken;
                // access token is very important to get some fields like email, birthday

                    getData();
                }
            }
        }


    function getData() {
        console.log('Welcome!  Fetching your information.... ');
        FB.api('/me', function(response) {
            console.log('Good to see you, ' + response.name + '.' + response.id);
        });
    };
