Minor【 PHP框架】6.代理

6.1 代理

　　Minor提供了一個類似於java中InvocationHandler介面和一個Proxy類的代理模式的實現，具體可參考我的這篇文章：http://www.cnblogs.com/orlion/p/5350752.html

　　6.1.1 使用

class FooController extends Controller
{
    public function bar($productName)
    {
       
        $log = new LogHandler();
        $shop = new Shop();
        $shopProxy = Proxy::newProxyInstance($shop, $log);
        $shopProxy->buy($productName);

    }
}

<?php

namespace App\Lib;

use Minor\Proxy\InvocationHandler;

class LogHandler implements InvocationHandler
{
    public function invoke($target, \ReflectionMethod $method, Array $args = [])
    {
        $this->before();
        $result = $method->invokeArgs($target, $args);
        $this->after();

        return $result;
    }

    public function before()
    {
        echo '[LogHandler] before<br/><br/>';
    }

    public function after()
    {
        echo '[LogHandler] after<br/><br/>';
    }
}

<?php

namespace App\Lib;

class Shop
{

    private $mail = null;

    public function boot(MailProvider $mail)
    {
        $this->mail = $mail;
    }

    public function buy($productName)
    {
        echo '[Shop] buy ' . $productName . '<br/><br/>';
        !is_null($this->mail) && $this->mail->send('DemoUser');
    }
}
