YII框架实现自定义第三方扩展操作示例


						本文实例讲述了YII框架实现自定义第三方扩展操作。分享给大家供大家参考，具体如下：



cat.php





<?php

/**

 * Created by PhpStorm.

 * Date: 2016/5/25

 * Time: 15:23

 */

namespace vendor\animal;

use \yii\base\Component;//组件

use \yii\base\Event;//

class myEvent extends Event{

  public $message;

}

class Cat extends Component{

  public function shout(){

    echo "miao miao miao<br>";

    //$this->trigger('miao');//事件命名

    $me = new myEvent();

    $me->message = "hello my Event<br>";

    $this->trigger('miao',$me);

  }

}







Dog.php





<?php

/**

 * Created by PhpStorm.

 * Date: 2016/5/25

 * Time: 17:00

 */

namespace vendor\animal;

use frontend\behaviors\behavior1;

use yii\base\Component;//让一个类拥有接收行为的能力

class Dog extends Component{

  public function behaviors(){

    return [

      Behavior1::className(),

    ];

  }

  public function look()

  {

    echo "I am looking!<br>";

  }

}







Mouse.php





<?php

/**

 * Created by PhpStorm.

 * Date: 2016/5/25

 * Time: 15:23

 */

namespace vendor\animal;

class Mouse{

  public function run($e)

  {

    echo $e->message;

    echo "I am running!<br>";

  }

}







controllers/AnimalController.php 调用第三方类库





<?php

/**

 * Created by PhpStorm.

 * Date: 2016/5/25

 * Time: 15:27

 */

//YII事件绑定

namespace frontend\controllers;

use yii;

use yii\web\Controller;

use vendor\animal\Cat;

use vendor\animal\Mouse;

use vendor\animal\Dog;

use \yii\base\Event;//类级别的事件绑定必须

use frontend\behaviors\Behavior1;//对象的混合

class AnimalController extends Controller{

  public function actionIndex(){

    $cat = new Cat();

    $mouse = new Mouse();

    $dog = new Dog();

    //对象级别的事件绑定

    $cat->on('miao',[$mouse,'run']);

    $cat->on('miao',[$dog,'look']);

//

//    $cat->off('miao',[$dog,'look']);//取消关注

    //类级别的事件绑定

//    Event::on(Cat::className(),'miao',[$mouse,'run']);//所有的老鼠都会监听这个miao事件

//    Event::on(Cat::className(),'miao',function(){

//      echo "miao event has triggerd!<br>";

//    });

    $cat->shout();

    //\Yii::$app是YII实现的单例模式

//    Yii::$app->on(\yii\base\Application::EVENT_AFTER_REQUEST,function(){

//      echo "event after request";

//    });

  }

  public function actionBehavior()//类的混合

  {

    /*板块1

     * $dog = new Dog();

    $dog->look();

    $dog->eat();*/

    $dog=new Dog();

    $dog->trigger("wang");

  }

  public function actionObject()//对象的混合

  {

    $dog = new Dog();

    $behavior1 = new Behavior1();

    $dog->attachBehavior('beh1',$behavior1);//取个别名，防止冲突

    //$dog->detachBehavior('beh1');//移除对象

    $dog->eat();

  }

}
