Question

我有两个网站和两个Facebook应用程序。现在我正在第二个网站上工作，我尝试在用Facebook登录后获取用户电子邮件地址。但是在另一个网站上工作的是什么，并没有解决这个问题。这是我的代码：

session_start();
// added in v4.0.0
require_once 'autoload.php';
use Facebook\FacebookSession;
use Facebook\FacebookRedirectLoginHelper;
use Facebook\FacebookRequest;
use Facebook\FacebookResponse;
use Facebook\FacebookSDKException;
use Facebook\FacebookRequestException;
use Facebook\FacebookAuthorizationException;
use Facebook\GraphObject;
use Facebook\Entities\AccessToken;
use Facebook\HttpClients\FacebookCurlHttpClient;
use Facebook\HttpClients\FacebookHttpable;
// init app with app id and secret
FacebookSession::setDefaultApplication( '****************','******************************' );
// login helper with redirect_uri
    $helper = new FacebookRedirectLoginHelper('http://mywebsite.com/fbconfig.php' );
try {
  $session = $helper->getSessionFromRedirect();
} catch( FacebookRequestException $ex ) {
  // When Facebook returns an error
} catch( Exception $ex ) {
  // When validation fails or other local issues
}
// see if we have a session
if ( isset( $session ) ) {
  // graph api request for user data
  $request = new FacebookRequest( $session, 'GET', '/me?locale=en_US&fields=id,name,email,first_name,last_name,gender,locale' );
  $response = $request->execute();
  // get response
  $graphObject = $response->getGraphObject();
        $fbid = $graphObject->getProperty('id');              // To Get Facebook ID
        $fbfullname = $graphObject->getProperty('name'); // To Get Facebook full name
        $fbemail = $graphObject->getProperty('email');    // To Get Facebook email ID
        $fbfirst = $graphObject->getProperty('first_name');
        $fblast = $graphObject->getProperty('last_name');
        $fbgender = $graphObject->getProperty('gender');
        $fblocale = $graphObject->getProperty('locale');
    /* ---- Session Variables -----*/
        $_SESSION['FBID'] = $fbid;           
        $_SESSION['FULLNAME'] = $fbfullname;
        $_SESSION['EMAIL'] =  $fbemail;
        $_SESSION['FIRST'] = $fbfirst;           
        $_SESSION['LAST'] = $fblast;
        $_SESSION['GENDER'] =  $fbgender;
        $_SESSION['LOCALE'] =  $fblocale;
    /* ---- header location after session ----*/
  header("Location: index.php?uid=log-in");
} else {
  $loginUrl = $helper->getLoginUrl( array('scope' => 'email'));
 header("Location: ".$loginUrl);
}

我甚至没有在以下行中收到电子邮件地址：

$fbemail = $graphObject->getProperty('email');    // To Get Facebook email ID

感谢您的帮助或想法。

$响应 - ＆GT; getGraphObject（）; 至 $响应 - ＆GT; getGraphUser（）;

如何从Facebook获取电子邮件地址？
