webman中检验signature的示例代码：

$symfony_request = new SymfonyRequest($request->get(), $request->post(), [], $request->cookie(), [], [], $request->rawBody());
$symfony_request->headers = new HeaderBag($request->header());
$this->app->setRequestFromSymfonyRequest($symfony_request);
$server = $this->app->getServer();
$data = $server->getDecryptedMessage();
var_dump($data->Encrypt,$data->toArray()); //这个怎么解密
$response = $server->serve();
return $response->getBody();

检验后可以怎么解密吗？求助， 提前感谢您

$data->Encrypt;
