Php 重构ZF2 ServiceLocatorAwareInterface以使用ZF3 in-view helper的最佳方法是什么?
由于Php 重构ZF2 ServiceLocatorAwareInterface以使用ZF3 in-view helper的最佳方法是什么?,php,zend-framework2,dependencies,zend-framework3,zf3,Php,Zend Framework2,Dependencies,Zend Framework3,Zf3,由于ServiceLocatorAwareInterfacedeprecation,我有来自ZF2的view helper,它不再与ZF3一起工作 重构该类的正确方法是什么: <?php namespace Site\View\Helper; use Zend\View\Helper\AbstractHelper; use Zend\ServiceManager\ServiceLocatorAwareInterface; use Zend\ServiceManager\ServiceL
ServiceLocatorAwareInterface
deprecation,我有来自ZF2的view helper,它不再与ZF3一起工作
重构该类的正确方法是什么:
<?php
namespace Site\View\Helper;
use Zend\View\Helper\AbstractHelper;
use Zend\ServiceManager\ServiceLocatorAwareInterface;
use Zend\ServiceManager\ServiceLocatorInterface;
class SlidersList extends AbstractHelper implements ServiceLocatorAwareInterface
{
protected $_serviceLocator;
public function __invoke()
{
return $this->getView()->render(
'partials/sliders',
array('sliders' => $this->getServiceLocator()->getServiceLocator()->get('Sliders/Model/Table/SlidersTable')->fetchAll(true))
);
}
public function setServiceLocator(ServiceLocatorInterface $serviceLocator)
{
$this->_serviceLocator = $serviceLocator;
}
public function getServiceLocator()
{
return $this->_serviceLocator;
}
}
否,您不应该使用工厂来注入ServiceLocator
实例(从不),而应该直接注入依赖项。在您的情况下,您应该插入SlidersTable
服务。你应该这样做:
1)使您的类构造函数依赖于您的滑块表
服务:
<?php
namespace Site\View\Helper;
use Zend\View\Helper\AbstractHelper;
use Sliders\Model\Table\SlidersTable;
class SlidersList extends AbstractHelper
{
protected $slidersTable;
public function __construct(SlidersTable $slidersTable)
{
return $this->slidersTable = $slidersTable;
}
public function __invoke()
{
return $this->getView()->render(
'partials/sliders',
array('sliders' => $this->slidersTable->fetchAll(true))
);
}
}
为什么在视图帮助器中需要服务定位器?问题在于这里,而不是如何将服务定位器提供给视图助手。我已经给出了一个答案。问题在于控制器而不是视图辅助对象,但是过程仍然是一样的。
<?php
namespace Site\View\Helper\Factory;
use Site\View\Helper\SlidersList;
use Interop\Container\ContainerInterface;
use Zend\ServiceManager\Factory\FactoryInterface;
class SlidersListFactory implements FactoryInterface
{
/**
* @param ContainerInterface $container
* @param string $requestedName
* @param array|null $options
* @return mixed
*/
public function __invoke(ContainerInterface $container, $requestedName, array $options = null)
{
$serviceManager = container
$slidersTable= $container->get('Sliders/Model/Table/SlidersTable');
return new SlidersList($slidersTable);
}
}
//...
'view_helpers' => array(
'factories' => array(
'Site\View\Helper\SlidersList' => 'Site\View\Helper\Factory\SlidersListFactory'
)
),
//...
