thinkphp 事件

使用助手函数注册事件

<?php
namespace app\index\controller;

use app\index\model\User;
class Index
{

    public function Index(){
        // 触发UserLogin事件 使用助手函数
        event('UserLogin');
        return "ming";
    }

}

生成事件类

php think make:event UserLogin

事件类添加方法

<?php

namespace app\event;

use app\index\model\User;

class UserLogin{
    public $user;

    public function _construct(User $user){
        $this->user = $user;
    }
}

这里依赖于model目录下的User类

事件类添加事件标识

此时目录如下

添加标识

// 事件定义文件
return [
    'bind'      => [
        'UserLogin' => 'app\event\UserLogin',
    ],

    'listen'    => [
        'AppInit'  => [],
        'HttpRun'  => [],
        'HttpEnd'  => [],
        'LogLevel' => [],
        'LogWrite' => [],
    ],

    'subscribe' => [
    ],
];

此时访问 http://localhost:8082/ 可以发现已经访问成功

事件监听

手动注册一个事件监听

    /**
     * 事件监听
     */
    public function listen(){
        Event::listen('UserLogin', function ($user){
            
        });
    }

可以使用命令行生成事件监听

php think make:listener UserLogin

事件订阅同理
