Question

我在facebook上有一个应用程序，我只使用了pagetabs，一切都很顺利。我点击了，我允许应用程序，请求权限，我允许，但现在它回到页面并且有一个错误，它重复加载...页面无法加载因为浏览器总是重新加载它，我不知道如何解决它...

非常感谢

这是我的代码：

<?php

require_once "sdk/facebook.php";

$app_id = "MY_APPID";
$app_secret = "MY_SECRET";

$is_fan = false;

// Init facebook api.
$facebook = new Facebook(array(
    'appId' => $app_id,
    'secret' => $app_secret,
    'cookie' => true
));

// Get and decode signed request.
$signed_request = $facebook->getSignedRequest();
if (isset($_REQUEST['signed_request'])) {
    $encoded_sig = null;
    $payload = null;
    list($encoded_sig, $payload) = explode(
        '.', $_REQUEST['signed_request'], 2
    );
    $sig = base64_decode(strtr($encoded_sig, '-_', '+/'));
    $data = json_decode(
        base64_decode(strtr($payload, '-_', '+/'), true)
    );
    $signed_request = $data;
}
else {
    $signed_request = false;
}

// Determine if we have a fan request.
if($signed_request) {
    if($signed_request->page->liked) {
        $is_fan = true;
    }
}

// for fans
if ($is_fan) { ?>

当某人是粉丝时，您的脚本始终正在执行：

window.top.location = oauth_url;

如果有人是粉丝，这将导致页面无限重新加载。

我找到了解决问题的方法。检查是否（$ is_fan）：

时更新此项

$user_id = $facebook->getUser();
if ($is_fan) {  
      if($user_id)
          {
               code after authentication and page Liked
          }

             }
else  {
          <script>
              var oauth_url = 'https://www.facebook.com/dialog/oauth/';
              ................ Next 4 lines same as the above code ..............
          </script>
      }

页面选项卡中的oauth facebook重新加载
