无法将app_data传递到我的Facebook标签页

Question

我尝试了一些解决方案，但似乎无法检索传递给我的Facebook标签页的“ app_data”。

UPDATE ----------------对于我的选项卡式页面，我正在使用以下内容，但它不起作用：

// Connect to Facebook
$facebook = new Facebook(array(
        'appId'  => $FB_APP_ID, 
        'secret' => $FB_APP_SECRET
));
$signed_request = $facebook->getSignedRequest();
echo ($signed_request["app_data"]);//Nothing is output here!

Answer 1

signed_request app_data用于页面标签应用，

对于常规的画布应用程序，这些值应仅可用于$_REQUEST['app_data']

Answer 2

$facebook = new Facebook(array(
    'appId' => '$testapp_id',
    'secret' => '$testapp_skey',
    'cookie' => true
));



$signed_request = $facebook->getSignedRequest();



$page_id = $signed_request["page"]["id"];
$page_admin = $signed_request["page"]["admin"];
$like_status = $signed_request["page"]["liked"];
$country = $signed_request["user"]["country"];
$locale = $signed_request["user"]["locale"];    
$fanpagid =$page_id;    

try {
$page_info  = $facebook->api("/".$page_id."?fields=link");
}catch(Exception $o) {
}

$fanpage=$page_info["link"];
$fullpageurl=$fanpage."?sk=app_".$app_id;

尝试使用此代码...
