Question

请有人帮助我。我差不多试了一个月......我想要检索消息和数据。我使用最新的FB API，我尽我所能找不到它的错误。我也无法撤回 user_id ..我是否需要在回叫功能上做任何事情？

应用网址：https://apps.facebook.com/greetingz/

这是我的整个代码

 <?php
    session_start();
    if(!empty($_REQUEST['request_ids'])) {
    require_once('src/facebook.php');

    $config = array();
    $config["appId"] = "XXXXXXXX";
    $config["secret"] = "XXXXXXXXXXXX";
    $config["fileUpload"] = false; // optional

    // Create our Application instance.
    $facebook = new Facebook(array(
      'appId'  => $config["appId"],
      'secret' => $config["secret"],
      'cookie' => true,
    ));

        $user_id= $facebook->getUser();

    if($user_id){
      try {

            $app_token = $facebook->getAccessToken();

            $requests = explode(',',$_REQUEST['request_ids']);
            foreach($requests as $request_id) {

            $data = $facebook -> api('/'.$user_id.'/apprequests?'.$app_token);

            //you will delete the request here
            $delete_url = "https://graph.facebook.com/".$request_id."_".$user_id."?".$app_token."&method=delete";
            $result = file_get_contents($delete_url);
        }

      } catch (FacebookApiException $e) {
        error_log($e);
        $user = null;
      }
    }else{
    ?>

    <script>
      var oauth_url = 'https://www.facebook.com/dialog/oauth/';
      oauth_url += '?client_id=XXXXXXXXXX';
      oauth_url += '&redirect_uri=' + encodeURIComponent('https://apps.facebook.com/greetingz/');
      oauth_url += '&scope=user_birthday,user_events'
      window.top.location = oauth_url;
    </script>

    <?php
    };
    }

    else{


    ?>

Buddy详细阅读this，它将解决您的问题，您需要解析signed_request，在signed_request中您获得user_id，您可以获得像这样的签名请求authResponse.signed_request

或者您可以使用Facebook图形api方法代替此行“$ user_id = $ facebook-＆gt; getUser（）;”在你的代码中。

FB.login(function(loginResponse) {
    if (loginResponse.authResponse) {
        var userId = loginResponse.authResponse.userID;

        // Work with userId here
        var signed_request = loginResponse.authResponse.signedRequest;
        //Work with signed request here
    }
    else {
        //User cancelled login or did not fully authorize        
    }
});

facebook user_id总是返回0
