我正在尝试为facebook应用添加类似的门。我正在使用最新的facebook PHP SDK，但即使页面被喜欢，也会显示封闭内容。代码如下：
<?php
require 'facebook.php';
$app_id = "xxxxxx";
$app_secret = "xxxxxxxxxx";
$loginNextPage = 'http://www.facebook.com/KillegarStables/'.'?sk=app_'.$app_id;
$facebook = new Facebook(array(
'appId' => $app_id,
'secret' => $app_secret,
'cookie' => true
));
$signed_request = $facebook->getSignedRequest();
$page_id = $signed_request["page"]["id"];
$like_status = $signed_request["page"]["liked"];
if ($like_status) {
// FOR FANS
$session = $facebook->getSession();
$loginUrl = $facebook->getLoginUrl(
array(
'canvas' => 1,
'fbconnect' => 0,
'next' => $loginNextPage,
'req_perms' => 'publish_stream,photo_upload,user_photos,user_photo_video_tags'
)
);
$fbme = null;
if (!$session) {
echo "<script type='text/javascript'>top.location.href = '$loginUrl';</script>";
exit;
}
else {
try {
$access_token = $facebook->getAccessToken();
$fbme = $facebook->api('/me');
$user = $facebook->getUser();
$url = "https://graph.facebook.com/".$user;
$info = file_get_contents($url);
$info = json_decode($info);
$vars = "id=$user&first_name=$info->first_name&last_name=$info->last_name&access_token=$access_token&pathToServer=$pathToServer&appName=$appName";
} catch (FacebookApiException $e) {
echo "<script type='text/javascript'>top.location.href = '$loginUrl';</script>";
exit;
}
// Begin Like Gated Content.

我对这个问题感到困惑。我已经看到提到导致问题的.htaccess，但没有提到解决方案。
答案 0 :(得分：1)
FB的文档说getSignedRequest返回一个字符串，而不是一个数组。
http://developers.facebook.com/docs/reference/php/facebook-getSignedRequest/
更多信息：

正如第二个链接所示，在不使用FB的php sdk的情况下完成此部分（解码请求）非常容易。
