ZF3: SharedEventManager注入EventManager

Question

在ZF2中，使用共享事件管理器在多个控制器之间共享事件。

Module.php

use Zend\Mvc\MvcEvent;

class Module
{
    public function getConfig()
    {
        return include __DIR__ . '/../config/module.config.php';
    }

    public function onBootstrap(MvcEvent $event)
    {
        $services = $event->getApplication()->getServiceManager();
        $sharedEventManager = $eventManager->getSharedManager();

        $sharedEventManager->attach('user', 'log-fail', function($event) use ($services) {
            $username = $event->getParam('username');
            $log = $services->get('log');
            $log->warn('Error logging user: ' . $username);
        });
    }
}

LogController.php

<?php

namespace Application\Controller;

use Zend\Mvc\Controller\AbstractActionController;
use Zend\EventManager\EventManager;

class LogController extends AbstractActionController
{
    public function __construct()
    {
    }

    public function inAction()
    {
        //...
        if (! $isValid) {
            $event = new EventManager('user');
            $event->trigger('log-fail', $this, array('username'=> $username));
            //...
        }
    }
}

但是ZF3要求在实例化时注入共享事件管理器，而不是通过setter注入。https://docs.zendframework.com/zend-eventmanager/migration/changed/

所以我创建了一个日志控制器工厂来注入共享事件管理器，但是我找不到如何执行注入

LogControllerFactory.php

<?php

namespace Application\Controller;

use Interop\Container\ContainerInterface;
use Zend\ServiceManager\Factory\FactoryInterface;

class LogControllerFactory implements FactoryInterface
{
    public function __invoke(ContainerInterface $container, $requestedName, array $options = null)
    {
        $sharedEventManager = ???

        return new LogController($sharedEventManager);
    }
}

您是否知道如何将共享事件管理器实例插入控制器中，以便将其插入控制器__construct函数中？

回答我自己的问题：

1. config.php

配置文件

/..
'controllers' => [
    'factories' => [
        Controller\LogController::class => Controller\LogControllerFactory::class,
        /..
    ],
    'aliases' => [
        'log' => Controller\LogController::class,
        /..
    ]
],
/..
'service_manager' => [
    'factories' => [
        'log' => Service\Log::class,
    ],
],
/..

2. Module.php

模块文件

namespace Application;

use Zend\Mvc\MvcEvent;

class Module
{
    public function getConfig()
    {
        return include __DIR__ . '/../config/module.config.php';
    }

    public function onBootstrap(MvcEvent $event)
    {
        // Get shared service manager
        $services = $event->getApplication()->getServiceManager();
        $sharedEventManager = $eventManager->getSharedManager();

        // Attach listener
        $sharedEventManager->attach('user', 'log-fail', function($event) use ($services) {
            $username = $event->getParam('username');
            $log = $services->get('log');
            $log->warn('Error logging user: ' . $username);
        });
    }
}

3. LogService.php

服务文件

namespace Application\Service;

use Interop\Container\ContainerInterface;
use Zend\ServiceManager\Factory\FactoryInterface;
use Zend\ServiceManager\ServiceLocatorInterface;
use Zend\Log\Logger;
use Zend\Log\Writer\Stream as StreamWriter;
use Zend\Log\Filter\Priority as PriorityFilter;

class Log implements FactoryInterface
{
    public function __invoke(ContainerInterface $container, $requestedName, array $options = null)
    {
        $controllerPluginManager = $container;
        $serviceManager = $controllerPluginManager->get('ServiceManager');

        // Instantiate Zend\Log\Logger
        $log = new Logger();
        // Set stream to write in a log file
        $writer = new StreamWriter('data/logs/audit.log');
        $log->addWriter($writer);

        return $log;
    }
}

4. LogControllerFactory.php*

控制器工厂文件

namespace Application\Controller;

use Interop\Container\ContainerInterface;
use Zend\ServiceManager\Factory\FactoryInterface;

class LogControllerFactory implements FactoryInterface
{
    public function __invoke(ContainerInterface $container, $requestedName, array $options = null)
    {
        $controllerPluginManager = $container;
        $eventManager = $controllerPluginManager->get('EventManager');
        $sharedEventManager = $eventManager->getSharedManager();

        return new LogController($sharedEventManager);
    }
}

5. LogController.php

控制器文件

namespace Application\Controller;

use Zend\Mvc\Controller\AbstractActionController;
use Zend\EventManager\EventManager;
use Zend\EventManager\SharedEventManager;

class LogController extends AbstractActionController
{
    public function __construct(SharedEventManager $sharedEventManager)
    {
        $this->_sharedEventManager = $sharedEventManager;
    }

    public function inAction()
    {
        //...
        if (! $isValid) {
            $event = new EventManager($this->_sharedEventManager, ['user']);
            $event->trigger('log-fail', $this, array('username'=> $username));
            //...
        }
    }
}
