Question

我的代码存在很大问题。我试着写我的第一个Facebook应用程序。但是这段代码无法从用户那里获得电子邮件，我也不知道为什么。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＆amp;朋友权限电子邮件，那么错误在哪里？这个应用程序工作正常，没有范围

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>";        
}

Answer 1

您这样做是正确的，但只会为已经为所有人显示其电子邮件的隐私选项的用户显示该电子邮件，否则它将不会显示该用户的电子邮件。

Answer 2

当且仅当用户在身份验证期间拒绝您访问时，Facebook才会返回用户的电子邮件。尝试打印请求facebook api返回的print_r($user_profile)。或者您可以使用opauth一个简单易用的php身份验证库希望它有所帮助
