zf2创建简单服务并通过viewhelper进行访问 [英] zf2 Creation of simple service and access it through viewhelper

问题描述

我正在尝试在zf2中创建一个简单的服务，我可以在viewhelper中使用该服务

I am trying to create a simple service in zf2 which I can access using in viewhelper

第1步.我在src/Application/Service/Service1.php中创建了一个类，如下所示:

Step1. I have craeted a class in src/Application/Service/Service1.php as follow

namespace Application\Service;
    use Zend\ServiceManager\ServiceLocatorAwareInterface;
    use Zend\ServiceManager\ServiceLocatorInterface;

    class Service1 implements ServiceLocatorAwareInterface
    {

        public function __construct()
        {

        }

        public function setServiceLocator(ServiceLocatorInterface $serviceLocator)
        {

        }    

        public function getServiceLocator()
        {

        }

    }

第2步，我在module.php文件中进行了如下设置.

Step2 I set this up in module.php file as below.

public function getServiceConfig()
{    
     return array(
        'factories' => array(
            'Application\Service\Service1' => function ($sm) {
                return new \Application\Service\Service1($sm);
            },
        )
    );   
}

public function onBootstrap($e)
{        
   $serviceManager = $e->getApplication()->getServiceManager();

    $serviceManager->get('viewhelpermanager')->setFactory('Abc', function ($sm) use ($e) {
        return new \Application\View\Helper\Abc($sm); 
    });
}

Step3 最后，我在这样的视图助手src/Application/View/Helper/Abc.php test()方法中得到它，II注释此行$this->sm->get('Application\Service\Service1');没有错误，服务中肯定缺少某些东西吗?

Step3 finally I am geting it in my view helper src/Application/View/Helper/Abc.php test() method like this, I I comment this line $this->sm->get('Application\Service\Service1'); there is no error, there must be something which I am missing in service?

namespace Application\View\Helper;

use Zend\View\Helper\AbstractHelper;

    class Abc extends AbstractHelper 
    {
       protected $sm;

       public function test()
        {
            $this->sm->get('Application\Service\Service1');
        }
        public function __construct($sm) {
            $this->sm = $sm;

        }
    }

Step4 ，然后我在这样的视图之一中调用我的测试视图助手.

Step4 then I am calling my test view helper in one of view like this.

$this->Abc()->test();

我遇到以下错误.

Fatal error: Call to undefined method Application\Service\Service1::setView() in vendor/zendframework/zendframework/library/Zend/View/HelperPluginManager.php on line 127 Call Stack:

我想念什么?

推荐答案

在以下方法中更改行$this->sm->getServiceLocator()->get('Application\Service\Service1');

class Abc extends AbstractHelper 
{
   protected $sm;

   public function test()
    {
        $this->sm->getServiceLocator()->get('Application\Service\Service1');
    }
    public function __construct($sm) {
        $this->sm = $sm;

    }
}
