How to test swoole

Swoole's heartbeat detection is very simple. You only need to configure heartbeat_check_interval and heartbeat_idle_time.

heartbeat_check_interval: Indicates that the server detects timeout every few seconds. Be smaller than heartbeat_idle_time. (Recommended learning: swoole video tutorial)

heartbeat_idle_time indicates how much time it takes to disconnect.

The sample code demonstrates, 5s detection, if there is a break within 10s If no data is sent to the server, it will be cut off

<?php
date_default_timezone_set(‘Asia/Shanghai‘);
//创建Server对象，监听 127.0.0.1:9501端口
$serv = new swoole_server("127.0.0.1", 9501);

$serv->set([
    ‘heartbeat_check_interval‘ => 5,
    ‘heartbeat_idle_time‘ => 10,
]);

//监听连接进入事件
$serv->on(‘connect‘, function ($serv, $fd) {
    echo "[".date(‘Y-m-d H:i:s‘)."]Client: Connect.\n";
});

//监听数据接收事件
$serv->on(‘receive‘, function ($serv, $fd, $from_id, $data) {
    $serv->send($fd, "[".date(‘Y-m-d H:i:s‘)."]Server: ".$data);
});

//监听连接关闭事件
$serv->on(‘close‘, function ($serv, $fd) {
    echo "[".date(‘Y-m-d H:i:s‘)."]Client: Close.\n";
});

//启动服务器
$serv->start();

The cli side starts the service.

Client access

The client first sends a request, the time is 2018-08-23 11:39:23, and will not send it later

Technology sharing pictures

The server disconnected the client at 2018-08-23 11:39:33. Exactly 10s
