2. Detail description about this issue(error/log)

   1： ✘ ykxiao@ip-192-168-43-20  ~  telnet 127.0.0.1 5291
   Trying 127.0.0.1...
   Connected to localhost.
   Escape character is '^]'.
   Welcome to cusService.
   2：监听TCP后，在控制器推送消息时提示："Swoole\WebSocket\Server::push(): the connected client of connection[2] is not a websocket client or closed"

3. Some reproducible code blocks and steps

   use Swoole\WebSocket\Server;
   /**
    * @return JsonResponse
    */
   public function tcpTest(): JsonResponse
   {
       /**@var \Swoole\Http\Server|Server $swoole */
       $swoole = app('swoole');
       $port = $swoole->ports[1];
       foreach ($port->connections as $fd) {
           if ($swoole->isEstablished($fd)) {
               $swoole->push($fd, 'Send TCP message');
           }
       }
       return $this->response->success();
   }

发TCP消息用send()，isEstablished()和push()是针对WebSocket的。
// $swoole->send($fd, 'Send tcp message');
