Facebook 应用程序身份验证错误

Question

当我尝试打开我的应用程序时 http://apps.facebook.com/allmyfrnds/allmyfriends.php 我收到此错误：

Fatal error: Call to undefined method Facebook::getSession() in E:\HostingSpaces\bombil\bombil.com\wwwroot\allmyfrnds\allmyfriends.php on line 14

我的代码是：

<?php  

   include_once ("src/facebook.php");  
   $app_id = '160888120643482';  
   $application_secret = 'bbae7def492082fa361da46185852e55';  

   $facebook = new Facebook(array(  
  'appId'  => $app_id,  
  'secret' => $application_secret,  
  'cookie' => true, // enable optional cookie support  
));  

    if ($facebook->getSession()) {  
    $user = $facebook->getUser();  
    $uid = $facebook->getUser();  
    $me = $facebook->api('/me/friends');  
    //echo "Total friends".sizeof($me['data'])."";  

    echo " <a href=\"http://www.bombil.com/\" target=\"_blank\" >Application Developed By Bombil Media</a> <br>";  
    foreach($me['data'] as $frns)  
    {  
    echo "<img src=\"https://graph.facebook.com/".$frns['id']."/picture\"" . "title=\"".$frns['name']."\"/".">";  

}  

    //echo " 

    //By <a href="\"http://facebook.com/nirbhay.singh\""><img src="\"https://graph.facebook.com/1147530774/picture\"" title="\"nirbhaysingh\"/"></a>";  

    }  
    else {  
    $loginUrl = "https://graph.facebook.com/oauth/authorize?type=user_agent&display=page&client_id=160888120643482
    &redirect_uri=http://apps.facebook.com/CANVAS URL/ 
    &scope=user_photos";  
    echo '<fb:redirect url="' . $loginUrl . '"></fb:redirect>';  
}  

?>  

但是当我上传此代码时

<?php  

   include_once ("src/facebook.php");  
   $app_id = '160888120643482';  
   $application_secret = 'bbae7def492082fa361da46185852e55';  

   $facebook = new Facebook(array(  
  'appId'  => $app_id,  
  'secret' => $application_secret,  
  'cookie' => true, // enable optional cookie support  
));  

    //if ($facebook->getSession()) {  
    $user = $facebook->getUser();  
    $uid = $facebook->getUser();  
    $me = $facebook->api('/me/friends');  
    //echo "Total friends".sizeof($me['data'])."";  

    echo " <a href=\"http://www.bombil.com/\" target=\"_blank\" >Application Developed By Bombil Media</a> <br>";  
    foreach($me['data'] as $frns)  
    {  
    echo "<img src=\"https://graph.facebook.com/".$frns['id']."/picture\"" . "title=\"".$frns['name']."\"/".">";  

}  

    //echo " 

    //By <a href="\"http://facebook.com/nirbhay.singh\""><img src="\"https://graph.facebook.com/1147530774/picture\"" title="\"nirbhaysingh\"/"></a>";  

    //}  
    //else {  
    //$loginUrl = "https://graph.facebook.com/oauth/authorize?type=user_agent&display=page&client_id=160888120643482
    //&redirect_uri=http://apps.facebook.com/CANVAS URL/ 
    //&scope=user_photos";  
    //echo '<fb:redirect url="' . $loginUrl . '"></fb:redirect>';  
//}  

?>  

，我收到此错误：

Fatal error: Uncaught OAuthException: An active access token must be used to query information about the current user. thrown in E:\HostingSpaces\bombil\bombil.com\wwwroot\allmyfrnds\src\base_facebook.php on line 988

请帮助....我将非常感谢您的帮助

Answer 1

代码看起来不错，问题是您没有登录来检索数据。
在打开此页面之前，请确保您在同一页面或其他页面中使用代码登录。
为了快速验证，您只需先登录 facebook.com 并尝试此页面，它应该可以工作。

登录成功后需要获取的访问令牌。

对于这个问题，请使用 try { } catch 语句包围您的代码。

编辑：类似这样的东西

可能 include_once 中的路径不正确。这就是您收到第一个错误的原因。查看手册以获取更多帮助。

<?php  
   include_once ("src/facebook.php");  
   $app_id = '160888120643482';  
   $application_secret = 'bbae7def492082fa361da46185852e55';  

  try {
   $facebook = new Facebook(array(  
     'appId'  => $app_id,  
     'secret' => $application_secret,  
     'cookie' => true, // enable optional cookie support  
    ));  

   if ($facebook->getSession()) {  
     $user = $facebook->getUser();  
     $uid = $facebook->getUser();  
     $me = $facebook->api('/me/friends');  
     //echo "Total friends".sizeof($me['data'])."";  

    echo " <a href=\"http://www.bombil.com/\" target=\"_blank\" >Application Developed By   Bombil Media</a> <br>";  
    foreach($me['data'] as $frns)  
    {  
      echo "<img src=\"https://graph.facebook.com/".$frns['id']."/picture\"" . "title=\"".$frns['name']."\"/".">"; 
    }
   }  
 } catch (FacebookApiException $e) {
      //echo "Error:" . print_r($e, true);
 }
?>

如果您使用的是 Linux 服务器，请确保路径正确，并确保文件名正确（即使区分大小写）

include_once ("src/facebook.php");
