http_server.php

$http = new swoole_http_server("0.0.0.0", 9501);
// 请求监听事件
$http->on('request', function ($request, $response) {
    var_dump($request->get, $request->post);

　0.0.0.0 means monitoring all IP addresses. A server may have multiple IPs at the same time, such as 127.0.0.1Local loopback IP, 192.168.1.100 LAN IP, 210.127.20.2 External network IP, you can also specify a separate IP to monitor here.

1. Start the service

$ /usr/local/php/bin/php http_server.php

2. After starting the service successfully, check netstat

$ ps aux | grep http_server
oosten     952  0.0  2.2 314544 23176 pts/3    Sl+  14:17   0:00 /usr/local/php/bin/php http_server.php
oosten     953  0.0  0.4 240212  4132 pts/3    S+   14:17   0:00 /usr/local/php/bin/php http_server.php
oosten     955  0.0  0.7 242620  7408 pts/3    S+   14:17   0:00 /usr/local/php/bin/php http_server.php　　

3. Simulate http request

$ sudo curl http://127.0.0.1:9501?param=1<h1>Hello Swoole.#1061</h1>

The server prints get/ post request data

$ /usr/local/php/bin/php http_server.php 
array(1) {
  ["param"]=>  string(1) "1"}
