1.手动监听

<?phpdeclare (strict_types = 1);namespace app\index\controller;use think\facade\Event;class Index{public function __construct(){Event::listen('first', function($param){echo $param . '+';});}public function index(){event('first', 'first success');return '您好！这是一个[index]示例应用';}}

2.监听器监听

<?php/** * Created by PhpStorm. * User: Administrator * Date: 2021/9/18 * Time: 14:46 */namespace app\index\listener;class TestListener{public function handle($event){//echo "testListner监听成功";}}

<?phpdeclare (strict_types = 1);namespace app\index\controller;use think\facade\Event;class Index{public function index(){Event::listen('test', 'app\index\listener\TestListener');event('test');return '您好！这是一个[index]示例应用';}}

3.修改event.php文件,添加事件监听

监听器还是上面的监听器

<?php/** * Created by PhpStorm. * User: Administrator * Date: 2021/9/18 * Time: 14:46 */namespace app\index\listener;class TestListener{public function handle($event){//echo "testListner监听成功";}}

修改event.php

<?php// 这是系统自动生成的event定义文件return ['listen'=> ['test' => ['app\index\listener\TestListener']]];

修改调用的代码

<?phpdeclare (strict_types = 1);namespace app\index\controller;use think\facade\Event;class Index{public function index(){event('test');return '您好！这是一个[index]示例应用';}}

4.事件订阅

添加订阅类

<?php/** * Created by PhpStorm. * User: Administrator * Date: 2021/9/18 * Time: 15:00 */namespace app\index\subscribe;class TestSub{public function onTestSub1(){echo "testSub1";}public function onTestSub2(){echo "testSub2";}}

修改event.php，绑定订阅类

<?php// 这是系统自动生成的event定义文件return ['listen'=> ['test' => ['app\index\listener\TestListener']],'subscribe' => ['app\index\subscribe\TestSub'],];

调用订阅的方法

<?phpdeclare (strict_types = 1);namespace app\index\controller;use think\facade\Event;class Index{public function index(){event('test');event('TestSub1');event('TestSub2');return '您好！这是一个[index]示例应用';}}

效果如下
