Laravel 应用中快速的创建不同类型的代理
经正祥
laravel-proxy-manager - 集成
Ocramius/ProxyManager到 Laravel 应用。
功能
- 快速创建不同类型的代理实例。
- 快速绑定不同类型的代理实例到容器。
- 快速扩展为不同类型的代理实例到容器。
安装
$ composer require guanguans/laravel-proxy-manager -vvv
$ php artisan vendor:publish --provider="Guanguans\\LaravelProxyManager\\ProxyManagerServiceProvider"
使用
获取代理管理器实例
app(\Guanguans\LaravelProxyManager\ProxyManager::class);
resolve(\Guanguans\LaravelProxyManager\ProxyManager::class);
代理管理器门面方法
<?php
namespace Guanguans\LaravelProxyManager\Facades;
/**

绑定虚拟代理示例(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()));

扩展为访问拦截器代理示例(切面)
ProxyManager::extendToAccessInterceptorValueHolderProxy(
LogManager::class,
[
'error' => static function (
object $proxy,
LogManager $realInstance,
string $method,
array $parameters,
bool &$returnEarly
){
dump('Before executing the error log method.');
}
],
[
'error' => static function (
object $proxy,
LogManager $realInstance,
string $method,
array $parameters,
&$returnValue,
bool &$overrideReturnValue
){
dump('After executing the error log method.');
}
]
);
dump($logger = app(LogManager::class));
$logger->error('What happened?');
