属性及回调 - eventHandler

说明:

callback BusinessWorker::$eventHandler

(注意：此特性需要GatewayWorker版本>=2.0.2，如何查看版本号参考《常见问题》一章)

(此属性一般不用设置)

设置使用哪个类来处理业务，默认值是Events，即默认使用Events.php中的Events类来处理业务。业务类至少要实现onMessage静态方法，onConnect和onClose静态方法可以不用实现。

(注意：Gateway 2.0.4版本以前业务处理类默认为Event，为了避免和Event扩展冲突，2.0.4版本以后统一改成Events)

范例

Applications项目start_businessworker.php

use WorkermanWorker;
use GatewayWorkerBusinessWorker;
$worker = new BusinessWorker();
$worker->name = 'ChatBusinessWorker';
$worker->count = 4;
$worker->registerAddress = '127.0.0.1:1236';
// 设置处理业务的类为MyEvent
$worker->eventHandler = 'MyEvent';
if(!defined('GLOBAL_START'))
{
    Worker::runAll();
}

Applications项目MyEvent.php

<?php
use GatewayWorkerLibGateway;
// MyEvent类
class MyEvent
{
    public static function onMessage($client_id, $message)
    {
        Gateway::sendToCurrentClient('works');
    }
}
