Facebook Connect - 获取电子邮件属性

Question

我正在开发一个使用Facebook API的应用程序。脸书连接。原来我无法获得电子邮件属性。问题出在哪里？

FB.init({
            appId  : 'CODE',
            status: true, 
            cookie: true, 
            xfbml: true, 
        });
        function statusFacebook() {
            FB.getLoginStatus(function(response) {
                if (response.status === 'connected') {
                        FB.api('/me', function(resp) {
                            var nome = resp.name;
                            var email = resp.email;
                            var token = response.authResponse.accessToken;
                        });
                } else if (response.status === 'not_authorized') {
                        loginFacebook(); // nao autorizado, solicitar login
                }
                else {
                        loginFacebook(); // nao autorizado, solicitar login
                }});
        }
        function loginFacebook() {
            FB.login(function(response) {
                    if (response.authResponse) {
                        FB.api('/me', function(resp) {
                            var nome = resp.name;
                            var email = resp.email;
                            var token = response.authResponse.accessToken;
                        }, {scope: 'email'});
                    }
            });
        }

拥有权限和其他人，但不起作用。按钮是：<a href="##" onClick="statusFacebook();">Login Facebook</a>

试试这个：

function loginFacebook() {
            FB.login(function(response) {
                    if (response.authResponse) {
                        FB.api('/me', function(resp) {
                            var nome = resp.name;
                            var email = resp.email;
                            var token = response.authResponse.accessToken;
                        });
                    }
            }, {scope: 'email'});
        }

如规范中所述，必须将scope声明为函数FB.login()第二个参数：

FB.login(function(response) {
   // handle the response
 }, {scope: 'email,user_likes'});
