Facebook连接的PHP-SDK在注销时生成错误

Question

我将示例中的代码复制到sdk中，并进行了一些小的更改（即使不进行更改，也会发生以下错误），并且脚本正确地登录了我。

它识别出我已连接，产生了适当的会话信息等。但是，注销链接facebook.com/logout.php?next= http://www.stockyardmagazine.com/fb/&access_token=xxyy将我发送到前述页面并引发错误。 “很抱歉，发生了错误。我们正在努力尽快解决此问题。” 此外，我仍保持登录状态。

这是我的代码中的问题，还是FB方面的问题？ 我正在http://www.stockyardmagazine.com/fb/中进行沙箱测试。 这是整个页面：

<?php
require 'facebook.php';

// Create our Application instance.
$facebook = new Facebook(array(
  'appId'  => 'numberxxyy',
  'secret' => 'abcdef123',
  'cookie' => true,
));


// We may or may not have this data based on a $_GET or $_COOKIE based session.
//
// If we get a session here, it means we found a correctly signed session using
// the Application Secret only Facebook and the Application know. We dont know
// if it is still valid until we make an API call using the session. A session
// can become invalid if it has already expired (should not be getting the
// session back in this case) or if the user logged out of Facebook.
$session = $facebook->getSession();

$me = null;
// Session based API call.
if ($session) {
  try {
    $uid = $facebook->getUser();
    $me = $facebook->api('/me');
  } catch (FacebookApiException $e) {
    error_log($e);
  }
}

// login or logout url will be needed depending on current user state.
if ($me) {
  $logoutUrl = $facebook->getLogoutUrl();
} else {
  $loginUrl = $facebook->getLoginUrl();
}


?>

    <?php else: ?>
    <strong><em>You are not Connected.</em></strong>
    <?php endif ?>
  </body>
</html>

我提供了一个连接按钮，该按钮具有较少的测试权限（如果对某些人来说很重要）。

谢谢！！

Answer 1

您首先需要具有fb-root DIV标记，然后调用FB.init()和FB.logout()

Answer 2

原始文件的第54行有一个fb-root div。

编辑的javascript如下； 现在页面不断刷新。

   <script>
          window.fbAsyncInit = function() {
            FB.init({
              appId   : '<?php echo $facebook->getAppId(); ?>',
              session : '<?php echo json_encode($session); ?>', // don't refetch the session when PHP already has it
              status  : true, // check login status
              cookie  : true, // enable cookies to allow the server to access the session
              xfbml   : true // parse XFBML
            });

            FB.logout(function(response) {
                // user is now logged out
            });

            FB.login(function(response) {
                // user is now logged out
            });

            // whenever the user logs in, we refresh the page
            FB.Event.subscribe('auth.login', function() {
               window.location.reload();
            });

          };

          (function() {
            var e = document.createElement('script');
            e.src = document.location.protocol + '//connect.facebook.net/en_US/all.js';
            e.async = true;
            document.getElementById('fb-root').appendChild(e);
          }());
        </script>

Answer 3

Sarfraz是正确的，但是您还有另一个问题。 在这里遵循您的逻辑：

    FB.logout(function(response) {
        // user is now logged out
    });

    FB.login(function(response) {
        // user is now logged out
    });

    // whenever the user logs in, we refresh the page
    FB.Event.subscribe('auth.login', function() {
       window.location.reload();
    });

您注销用户，然后登录用户，然后订阅登录事件，该事件将重新加载页面。 页面重新加载后，您将再次注销它们，然后重新刷新广告。

请记住，这些是异步调用。 他们中的任何一个都可以先返回。 如果您确实想要这种逻辑，那么应该这样写：

   window.fbAsyncInit = function() {
        FB.init({
          appId   : '<?php echo $facebook->getAppId(); ?>',
          session : '<?php echo json_encode($session); ?>', // don't refetch the session when PHP already has it
          status  : true, // check login status
          cookie  : true, // enable cookies to allow the server to access the session
          xfbml   : true // parse XFBML
        });

        FB.logout(function(response) {
            // user is now logged out
            FB.login(function(response) {
                // user is now logged out
                // whenever the user logs in, we refresh the page
                FB.Event.subscribe('auth.login', function() {
                   window.location.reload();
                });
            });
        });
     };

但我仍然不明白要点...
