我有一个带有“赞”按钮的示例应用。它以前有效，但现在无效。 我之前在 jsfiddle.net 上测试过它，它也可以工作。但是在我将文件上传到服务器后，它出现了一个错误。 “赞”按钮弹出，然后出现此错误:
我已经读过这个 article已经在 SO 上并遵循了答案，但仍然没有用。对此错误有何看法？
附言: 总而言之，我对此还很陌生。
这是我使用的示例代码:
<?php
include_once("../incs/dbcon.php");
require_once('AppInfo.php');
require_once('utils.php');
require_once('../sdk/src/facebook.php');
//This gets the signed_request from FB which checks the 'liked' status on the current page
$signed_request = $_REQUEST["signed_request"];
list($encoded_sig, $payload) = explode('.', $signed_request, 2);
$data = json_decode(base64_decode(strtr($payload, '-_', '+/')), true);
$app_data = isset($data["app_data"]) ? $data["app_data"] : '';
$_REQUEST["fb_page_id"] = $data["page"]["id"];
$access_admin = $data["page"]["admin"] == 1;
$has_liked = $data["page"]["liked"] == 1;
$facebook = new Facebook(array(
'appId' => AppInfo::appID(),
'secret' => AppInfo::appSecret(),
));
$user_id = $facebook->getUser();
if ($user_id) {
try {
// Fetch the viewer's basic information
$basic = $facebook->api('/me');
} catch (FacebookApiException $e) {
// If the call fails we check if we still have a user. The user will be
// cleared if the error is because of an invalid accesstoken
if (!$facebook->getUser()) {
header('Location: '. AppInfo::getUrl($_SERVER['REQUEST_URI']));
exit();
}
}
// This fetches some things that you like . 'limit=*" only returns * values.
// To see the format of the data you are retrieving, use the "Graph API
// Explorer" which is at https://developers.facebook.com/tools/explorer/
$likes = idx($facebook->api('/me/likes?limit=4'), 'data', array());
// This fetches 4 of your friends.
$friends = idx($facebook->api('/me/friends?limit=4'), 'data', array());
// And this returns 16 of your photos.
$photos = idx($facebook->api('/me/photos?limit=16'), 'data', array());
// Here is an example of a FQL call that fetches all of your friends that are
// using this app
$app_using_friends = $facebook->api(array(
'method' => 'fql.query',
'query' => 'SELECT uid, name FROM user WHERE uid IN(SELECT uid2 FROM friend WHERE uid1 = me()) AND is_app_user = 1'
));
}
// Fetch the basic info of the app that they are using
$app_info = $facebook->api('/'. AppInfo::appID());
$app_name = idx($app_info, 'name', '');

最佳答案
此消息是 Facebook 用来阻止 Like-jacking 和防止垃圾邮件的消息。如果“赞”按钮是第一次添加到网站/域，它也会出现。给它时间，一旦 Facebook 认为您的网站没有执行上述任何操作，消息就会消失。
