我的Facebook应用程序在Firefox中运行良好,但在点击链接时在IE中表现得很奇怪:它一直重定向,当点击iFrame中的链接时,它最终会重定向回index.php而不保留GET-Vars链接。它似乎总是重定向到authentification-URL。

这是我的画布页面的核心部分:index.php:

    <?

require 'facebook-php-sdk-6c82b3f/src/facebook.php';

$facebook = new Facebook(array(
  'appId'  => 'XXX',
  'secret' => 'YYY',
));


function get_facebook_cookie($app_id, $application_secret) {
  $args = array();
  parse_str(trim($_COOKIE['fbs_' . $app_id], '"'), $args);
  ksort($args);
  $payload = '';
  foreach ($args as $key => $value) {
    if ($key != 'sig') {
      $payload .= $key . '=' . $value;
    }
  }
  if (md5($payload . $application_secret) != $args['sig']) {
    return null;
  }
  return $args;
}


$cookie = get_facebook_cookie('XXX',  'YYY');

// Get User ID
$user = $facebook->getUser();


if ($user) {
  try {
    // Proceed knowing you have a logged in user who's authenticated.
    $user_profile = $facebook->api('/me');
  } catch (FacebookApiException $e) {
    error_log($e);
    $user = null;
  }
}

?>


<body onload="self.focus();document.tips.tip0A.focus()" scroll="no" style="overflow:hidden">
<div id="fb-root"></div>
<script type="text/javascript">
    window.fbAsyncInit = function () {
        FB.init({ appId: 'XXX', status: true, cookie: true, xfbml: true });
        FB.Canvas.setSize({ height: 890 });
    };
    (function () {
        var e = document.createElement('script');
        e.type = 'text/javascript';
        e.src = document.location.protocol +
            '//connect.facebook.net/en_US/all.js';
        e.async = true;
        document.getElementById('fb-root').appendChild(e);
    } ());
</script>


<?
if (!$user_profile[id]) {?>
<script>
  var oauth_url = 'https://www.facebook.com/dialog/oauth/';
  oauth_url += '?client_id=429812627032252';
  oauth_url += '&redirect_uri=' + encodeURIComponent('https://apps.facebook.com/euro_challenge/');
  oauth_url += '&scope=email,user_birthday'

  window.top.location = oauth_url;
</script>
<?}?>

有什么想法吗?

Facebook建议使用伪造的P3P标题只是为了让IE开心。小心发出“真正的”P3P标题,因为它暗示您已制定了特定的隐私政策。它不仅仅是随机字符。

在此页http://developers.facebook.com/docs/samples/canvas/的开发者文档中,Facebook建议:

P3P: CP="HONK"
