facebook connect 没有 return 电子邮件地址

Question

我正在使用这个简单的 FB 连接

<a href="#" onclick="fb_login();">Connect</a>

window.fbAsyncInit = 函数() { FB.init({ 应用程序 ID：'YOUR_APP_ID'， oauth：是的， status : true, // 检查登录状态 cookie : true, // 启用 cookie 以允许服务器访问会话 xfbml : true // 解析 XFBML });

};

function fb_login(){
    FB.login(function(response) {

        if (response.authResponse) {
            console.log('Welcome!  Fetching your information.... ');
            console.log(response); // dump complete info
            access_token = response.authResponse.accessToken; //get access token
            user_id = response.authResponse.userID; //get FB UID

            FB.api('/me', function(response) {
                user_email = response.email; //get user email
                console.log(response); 

            });

        } else {
            //user hit cancel button
            console.log('User cancelled login or did not fully authorize.');    
        }
    }, {
        scope: 'email'
    });
}
(function() {
    var e = document.createElement('script');
    e.src = document.location.protocol + '//connect.facebook.net/en_US/all.js';
    e.async = true;
    document.getElementById('fb-root').appendChild(e);
}());

当我连接时，它只有 returns 我

Object {name: "my name here", id: "102xxxxxxxx230"}

如何找回电子邮件地址？

Answer 1

FB.api('/me', {fields: 'name,email'}, function(response) {
    user_email = response.email; //get user email
    console.log(response); 
});

它叫做 "Declarative Fields"，请参阅更新日志：https://developers.facebook.com/docs/apps/changelog#v2_4
