结构型--代理模式

设计模式

• 抽象主题接口
• 真实主题类
• 代理角色

抽象主题接口

<?php
/**
 * Subject.php
 *
 * @author     Luffy <lufei@swoole.com>
 * @date       2019/12/16
 * @copyright  Swoole, Inc.
 * @package    sy-records/design-patterns
 */
namespace Luffy\DesignPatterns\Proxy;
interface Subject
{
    public function get();
    public function put();
}

真实主题类

<?php
/**
 * RealSubject.php
 *
 * @author     Luffy <lufei@swoole.com>
 * @date       2019/12/16
 * @copyright  Swoole, Inc.
 * @package    sy-records/design-patterns
 */
namespace Luffy\DesignPatterns\Proxy;
class RealSubject implements Subject
{
    public function get()
    {
        echo __CLASS__ . " get\n";
    }
    public function put()
    {
        echo  __CLASS__ . " put\n";
    }
}

代理角色

<?php
/**
 * Proxy.php
 *
 * @author     Luffy <lufei@swoole.com>
 * @date       2019/12/16
 * @copyright  Swoole, Inc.
 * @package    sy-records/design-patterns
 */
namespace Luffy\DesignPatterns\Proxy;
class Proxy
{
    /**
     * @var RealSubject
     */
    protected $realSubject;
    /**
     * Proxy constructor.
     */
    public function __construct()
    {
        $this->realSubject = new RealSubject();
    }
    public function __call($name, $arguments)
    {
        return $this->realSubject->{$name}(...$arguments);
    }
//    public function get()
//    {
//        $this->realSubject->get();
//    }
    public function send()
    {
        echo  __CLASS__ . " send\n";
    }
}

客户端调用

<?php
/**
 * Client.php
 *
 * @author     Luffy <lufei@swoole.com>
 * @date       2019/12/16
 * @copyright  Swoole, Inc.
 * @package    sy-records/design-patterns
 */
namespace Luffy\DesignPatterns\Proxy;
include __DIR__ . '/../vendor/autoload.php';
class Client
{
    public static function run()
    {
        $proxy = new Proxy();
        $proxy->get();
        $proxy->put();
        $proxy->send();
    }
}
Client::run();
