只希望訂閱者的角色用戶登錄到應用程序。我不知道獲得在WordPress用戶的角色。這裏是我的代碼

$u_name = $_POST['userName']; 
$password = $_POST['password']; 
$username = $u_name; 

//$tokenID = $_GET['tokenID']; 
$vendor_list = array(); 
if (username_exists($username)) 
    { 

     $user = get_user_by('login', $username); 

     if ($user && wp_check_password($password, $user->user_pass, $user->ID)) 
     { 
     $email = $user->user_email; 
     $vendor_list[] = array("userID"=>$user->ID,"userName" =>$username,"email" =>$email); 
     echo json_encode($vendor_list); 
     } 
     else 
     { 
     $testing = 2; 
     echo json_encode($testing); 
     } 
    } 
    else 
    { 
     $testing = 1; 
     echo json_encode($testing); 
    }
