我已使用facebook开发者帐户注册了新应用程序。在下面的教程中,我有以下代码:

    <?php
  // Remember to copy files from the SDK's src/ directory to a
  // directory in your application on the server, such as php-sdk/
  require_once('facebook/facebook.php');

  $config = array(
    'appId' => 'xxxxxxxxxxxx',
    'secret' => 'yyyyyyyyyyyyyy',
    'allowSignedRequest' => false // optional but should be set to false for non-canvas apps
  );

  $facebook = new Facebook($config);
  $user_id = $facebook->getUser();
?>
<html>
  <head></head>
  <body>

  <?php
    if($user_id) {

      // We have a user ID, so probably a logged in user.
      // If not, we'll get an exception, which we handle below.
      try {

        $user_profile = $facebook->api('/me','GET');
        echo "Name: " . $user_profile['name'];

      } catch(FacebookApiException $e) {
        // If the user is logged out, you can have a 
        // user ID even though the access token is invalid.
        // In this case, we'll get an exception, so we'll
        // just ask the user to login again here.
        $login_url = $facebook->getLoginUrl(); 
        echo 'Please <a href="' . $login_url . '">login.</a>';
        error_log($e->getType());
        error_log($e->getMessage());
      }   
    } else {

      // No user, print a link for the user to login
      $login_url = $facebook->getLoginUrl();
      echo 'Please <a href="' . $login_url . '">login.</a>';

    }

  ?>

  </body>
</html>

如何修复它?

我也遇到了同样的问题,我发现我的“重定向uri”和“有效的OAuth重定向uri”不匹配。

在我的代码中,我设置了:

redirect_uri = "http://www.website.com/validate.php";
但在我的Facebook应用程序中,我设置了有效的OAuth重定向URI:

http://website.com/validate.php
我所缺少的只是“www”。因此,我在我的Facebook应用程序中添加了另一个有效的OAuth重定向URI:

http://www.website.com/validate.php



我像魔术一样为我工作。

希望对您有所帮助。

在仪表板上,您是否添加了
buzzsu.com
www.buzzsu.com
?这很重要,好吧!我为www.buzzsu.com编辑了应用程序设置。然后在firefox中,我键入了buzzsu.com,但它不起作用,在我尝试键入www.buzzsu.com后,它起作用了。有什么问题?
http://www.website.com/validate.php
