关于php:Laravel-应用中快速的创建不同类型的代理

laravel-proxy-manager – 集成 Ocramius/ProxyManager 到 Laravel 利用。

性能

• 疾速创立不同类型的代理实例。
• 疾速绑定不同类型的代理实例到容器。
• 疾速扩大为不同类型的代理实例到容器。

装置

$ composer require guanguans/laravel-proxy-manager -vvv

$ php artisan vendor:publish --provider="Guanguans\\LaravelProxyManager\\ProxyManagerServiceProvider"

应用

获取代理管理器实例

app(\Guanguans\LaravelProxyManager\ProxyManager::class);
resolve(\Guanguans\LaravelProxyManager\ProxyManager::class);

绑定虚构代理示例 (懒初始化)

<?php

namespace App;

use App\Foo;
use Guanguans\LaravelProxyManager\Facades\ProxyManager;
use SebastianBergmann\Timer\ResourceUsageFormatter;
use SebastianBergmann\Timer\Timer;

class Foo
{
    /** @var string */
    private $bar;

    public function __construct(string $bar = 'bar')
    {
        $this->bar = $bar;
        sleep(3);
    }

    public function getBar(): string
    {return $this->bar;}
}

// ProxyManager::bindLazyLoadingValueHolderProxy(Foo::class);
ProxyManager::singletonLazyLoadingValueHolderProxy(Foo::class);

$formatter = new ResourceUsageFormatter();
$timer = new Timer();
$timer->start();
$timer->start();

// 初始代理类时不会调用原类的构造函数
dump($foo = app(Foo::class), $formatter->resourceUsage($timer->stop()));
// 当真正调用时才会调用原类的构造函数
dump($foo->getBar(), $formatter->resourceUsage($timer->stop()));

扩大为拜访拦截器代理示例 (切面)

ProxyManager::extendToAccessInterceptorValueHolderProxy(
