php - 我无法在 Facebook 上获取用户电子邮件地址

Question

我对这段代码有很大的疑问。我尝试编写我的第一个 Facebook 应用程序。但是这段代码无法收到用户的电子邮件，我不知道为什么。有人能帮我吗？

require_once 'phpmailer.php';
require_once 'facebook.php';

error_reporting(0);
//Application Configurations
$app_id     = 'MY APP ID';
$app_secret = 'MY SECRET ID';
$site_url   = 'MY SITE URL';
// Create our application instance
$facebook = new Facebook(array(
    'appId'     => $app_id,
    'secret'    => $app_secret,
    'cookie'=>true,
));

$user = $facebook->getUser();

if($user == 0){
    $user = $facebook->getUser();
}
if($user){
    $user_profile=$facebook->api('/me');    
    $logoutUrl= $facebook->getLogoutUrl();
    if(empty($_POST['send'])){
        echo"<form method='POST'>";
        echo"Hi ".$user_profile['name']."</br>";

        echo"<textarea name='message' rows='6' cols='80'>";
        echo"</textarea>";
        echo"<input type='submit' name='send' value='send'>";
        echo"</form>";
    }
    if(!empty($_POST['send'])&& empty($_POST['message'])){
        echo "Empty message";
    }
    if(!empty($_POST['send'])){
        $mail = new PHPMailer();
        $mail->SetFrom($_POST['mail'],$user_profile['name']);
        $mail->CharSet="utf-8";
        $address="therimsilua@gmail.com";
        $mail->AddAddress($address," ");
        $mail->Subject="message from facebook";
        $wiadomosc='Message from user'.$user_profile['name'].'</br>'.$_POST['message'];
        $mail->MsgHTML($message); 
        if($mail->Send()){
            echo "Send to: ".$user_profile['email']; 
        }
        else{           
            echo "Error:".$mail->ErrorInfo;
        }
    }               
}
else {
    $perm = array('scope'=>'email');
    $loginUrl =$facebook->getLoginUrl($perm);       
}

在应用程序设置中我有用户和 friend 权限电子邮件，那么错误在哪里？这个应用程序在没有范围的情况下工作正常

require_once "facebook.php";

$facebook = new Facebook(array('appId'  => '482455065177441', 'secret' => '0e484981225df74f1170c29185aa8690'));  

$user_fb = $facebook->getUser();

if($user_fb == 0)
{
    $user_fb = $facebook->getUser();
}

if ($user_fb) // Check user's FB user ID has getting or not
{   
$user_profile = $facebook->api('/me'); 

$logoutUrl = $facebook->getLogoutUrl(); 

echo $user_profile['email'];
echo $user_profile['first_name'];
echo $user_profile['last_name'];            
}

else // user's FB user ID has not getting load login url with email permission
{     
 $perms = array('scope' => 'email');
 $loginUrl = $facebook->getLoginUrl($perms);        
 echo "<script> top.location.href='" . $loginUrl . "'</script>";        
}

您做对了，但是电子邮件只会显示给已将其电子邮件的隐私选项设置为向所有人显示的用户，否则它不会向您显示该用户的电子邮件。
