如何在一个tcp的服务中，返回给客户端http json

<?php
require_once __DIR__ . '/vendor/autoload.php';
use Workerman\Worker;
use Workerman\Protocols\Http\Response;
$worker = new Worker('tcp://0.0.0.0:12345');
$worker->onMessage = function($connection, $request)
{
     $data = json_encode(['code' => 0, 'data' => [1,2,3]]);
     $response = new Response(200, ['Content-Type' => 'application/json'], $data);
     $connection->send($response);
};

Worker::runAll();
