不会重定向到 ie 或 chrome 中的画布

Question

我在粉丝页面上单击 chrome 中的应用程序选项卡时遇到问题，屏幕为空白，在 ie 中显示“此内容无法在框架中显示”，我尝试添加 header('P3P: CP="CAO PSA OUR"');到我的画布上没有运气。有什么建议吗？我真的被困在这里了，谢谢！ 这是我画布上的代码

<?php 

$app_id = "181247898619054";
$app_secret = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
$my_url = "https://apps.facebook.com/wellnessiq/";
session_register();
session_start();
header('P3P: CP="CAO PSA OUR"');

if (!isset($_REQUEST["code"]))
{
 $_SESSION['state'] = md5(uniqid(rand(), TRUE)); //CSRF protection
 $dialog_url = "https://www.facebook.com/dialog/oauth?client_id=" 
   . $app_id . "&redirect_uri=" . urlencode($my_url) . "&scope=email&state="
   . $_SESSION['state'];

 echo("<script> top.location.href='" . $dialog_url . "'</script>");
exit;
}
 $code = $_REQUEST['code'];
 {
  $token_url = "https://graph.facebook.com/oauth/access_token?"
   . "client_id=" . $app_id . "&redirect_uri=" . urlencode($my_url)
   . "&client_secret=" . $app_secret . "&code=" . $code;

 $response = file_get_contents($token_url);
 $params = null;
  parse_str($response, $params);

  $graph_url = "https://graph.facebook.com/me?access_token=" 
   . $params['access_token'];

  $user = json_decode(file_get_contents($graph_url));
}

?>
