php - How does swoole's http service call tcp service? Can I open a tcp_client only when the http service is onWorkerStart?

Question

Please tell me how to call the tcp service in swoole's bttp service. Can I only open a tcp_client when http service onWorkerStart?

Some people also say to monitor the port, but it seems that you cannot monitor the http port.

Thanks.

$server->listen("127.0.0.1", 9501, SWOOLE_SOCK_TCP);

For detailed code, you can go to the swoole website to search for the listen keyword
