谢谢,Enamul

<?php ?>
<div id="fb-root"></div>
<script>
  // Additional JS functions here
  window.fbAsyncInit = function() {
    FB.init({
      appId      : 'f', // App ID
      channelUrl : '//localhost/practices/phpTest/fblogin/login.php/channel.html', // Channel File
      status     : true, // check login status
      cookie     : true, // enable cookies to allow the server to access the session
      xfbml      : true  // parse XFBML
    });
    FB.getLoginStatus(function(response) {
    if (response.status === 'connected') {
        // connected
    } else if (response.status === 'not_authorized') {
        // not_authorized
      login();
    } else {
        // not_logged_in
      login();
    }
    });

    // Additional init code here

  };

  function login() {
    FB.login(function(response) {
        if (response.authResponse) {
            // connected
          testAPI();
        } else {
            // cancelled
        }
    });
    }

  function testAPI() {

    console.log('Welcome!  Fetching your information.... ');
    FB.api('/me', function(response) {

        console.log('Good to see you, ' + response.name + '.');
    });
  }

  // Load the SDK Asynchronously
  (function(d){
     var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
     if (d.getElementById(id)) {return;}
     js = d.createElement('script'); js.id = id; js.async = true;
     js.src = "//connect.facebook.net/en_US/all.js";
     ref.parentNode.insertBefore(js, ref);
   }(document));
</script>
<?php ?>

Answer 1

除了将scope ="email"添加到按钮之外,还需要指定要返回的字段.

<fb:login-button scope="public_profile, email" onlogin="checkLoginState();" data-auto-logout-link="true" data-size="large">

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

有关完整的代码结构,请查看facebook文档.

Answer 2

与访问名称的方式相同。IE

response.email和response.id

但要获取电子邮件地址，您必须拥有访问它的权限。

添加scope="email"到您的 FB 登录按钮。

function login() {
    FB.login(function(response) {
        if (response.authResponse) {
            // connected
        testAPI();
        } else {
            // cancelled
        }
    }, { scope: 'email' });
    }

function testAPI() {

    console.log('Welcome!  Fetching your information.... ');
    FB.api('/me', function(response) {

        console.log('Good to see you, ' + response.name + '.' + ' Email: ' + response.email + ' Facebook ID: ' + response.id);
    });
}
