Laradock

on("start", function ($server) { echo "Swoole http server is started at http://127.0.0.1:9501\n"; }); // 向服务器发送请求时返回响应 // 可以获取请求参数，也可以设置响应头和响应内容 $server->on("request", function ($request, $response) { $response->header("Content-Type", "text/plain"); $response->end("Hello World\n"); }); // 启动 HTTP 服务器 $server->start();

In this way, a most basic The HTTP server is completed. Its working principle is similar to that of industrial-grade Apache and Nginx servers, except that it provides the simplest server monitoring and response functions. We enable this server in the terminal:
