Facebook PHP SDK-安装用户应用程序后无app_data

Question

I'm having an issue with passing app_data after a new app install redirect using the Facebook PHP SDK

$loginUrl = $facebook->getLoginUrl( array( 'scope' => 'email,manage_pages', 'redirect_uri' => $fbconfig['appPageUrl'], ) );

$decodedSignedRequest = parse_signed_request($_REQUEST['signed_request'], $fbconfig['secret']); 

if (isset($decodedSignedRequest['app_data'])){
    echo $app_data=$decodedSignedRequest['app_data'];
    header("Location: success.php?id=$app_data");
    die();
}

If the app is installed I get app_data from the signed_request without a problem.

Any suggestions?

Your Location header is wrong , because it requires an absolute URL by definition.

And if you append a query string ?id=1234, then you can access that value via $_GET['id'] in your script.
