提供监听逻辑。命令解析选定的路径以查找所有监听器/订阅者（依赖于ListenerInterface和SubscriberInterface实现）。监听器可以用于单个事件，而订阅者可以用于多个事件。

安装

运行以下命令

php composer.phar require --prefer-dist yiicod/yii2-listener "*"

或者将以下内容添加到你的composer.json文件中

"yii2-listener": "*"

到

Web配置

'bootstrap' => ['listener'],
'components' => [
    'listener' => [
        'class' => 'yiicod\listener\components\Listener'
    ],
]

控制台配置

'controllerMap' => [
    'listener' => [
        'class' => \yiicod\listener\commands\Listener::class
    ],
]

运行命令。此命令将预热和准备所有监听器和订阅。每次创建新的监听器或订阅时，请运行此命令。

listener/parse

要触发事件，请参阅yii手册：https://yiiframework.cn/doc-2.0/guide-concept-events.html#class-level-event-handlers

监听器使用

namespace frontend\observers\listeners;

use yii\db\ActiveRecord;
use yiicod\listener\components\listeners\ListenerAbstract;

class TestListener extends ListenerAbstract
{
   /**
    * Call on event method
    */
   public function handle($event)
   {
       // TODO: Implement handle() method.
   }

   /**
    * Return event name for emit
    * @return string
    */
   public static function event(): string
   {
       return ActiveRecord::class . '@' . ActiveRecord::EVENT_AFTER_FIND;
   }
}

订阅者使用

namespace frontend\observers\subscribers;

use yii\db\ActiveRecord;
use yiicod\listener\components\listeners\SubscriberAbstract;

class TestSubscriber extends SubscriberAbstract
{
   /**
    * @return array
    * [
    *      'event_class@event1' => 'on'
    *      'event_class@event2' => 'on'
    * ]
    */
   public static function subscribe(): array
   {
       return [
           ActiveRecord::class . '@' . ActiveRecord::EVENT_BEFORE_INSERT => 'on',
           ActiveRecord::class . '@' . ActiveRecord::EVENT_AFTER_INSERT => 'on'
       ];
   }

   /**
    * Call on event method
    */
   public function on($event)
   {
       // Handle
   }
}
