如何在zf2中获取控制器和操作名称

Dev*_*per 5 php zend-framework2

在zf1中,我们可以使用获取控制器和动作名称

$controller = $this->getRequest()->getControllerName();
$action = $this->getRequest()->getActionName();

我们如何在zf2中实现这一目标?

更新:我试图让他们使用

echo $this->getEvent()->getRouteMatch()->getParam('action', 'NA');
echo $this->getEvent()->getRouteMatch()->getParam('controller', 'NA');

但我收到了错误

Fatal error: Call to a member function getParam() on a non-object

我喜欢在__construct()方法中获取它们;

理想情况下,我想检查是否没有定义Action将执行noaction()方法.我会检查使用php方法method_exists.

更简单:

$controllerName =$this->params('controller');
$actionName = $this->params('action');

您无法在控制器__construct()方法中访问这些变量,但可以在dispatch方法和onDispatch方法中访问它们。

但是如果您想检查操作是否存在,在 zf2 中已经有一个针对 notFoundAction 的内置函数,如下所示

 public function notFoundAction()
{
    parent::notFoundAction();
    $response = $this->getResponse();
    $response->setStatusCode(200);
    $response->setContent("Action not found");
    return $response;   
}

但如果您仍然喜欢手动执行此操作,您可以使用调度方法执行此操作,如下所示

namespace Mynamespace\Controller;

use Zend\Mvc\Controller\AbstractActionController;

use Zend\Stdlib\RequestInterface as Request;
use Zend\Stdlib\ResponseInterface as Response;
use Zend\Mvc\MvcEvent;

class IndexController extends AbstractActionController 
{

    public function __construct()
    {


    }        

      public function notFoundAction()
    {
        parent::notFoundAction();
        $response = $this->getResponse();
        $response->setStatusCode(200);
        $response->setContent("Action not found");
        return $response;   
    }

    public function dispatch(Request $request, Response $response = null)
    {
        /*
         * any customize code here
         */

        return parent::dispatch($request, $response);
    }
    public function onDispatch(MvcEvent $e)
    {
        $action = $this->params('action');
        //alertnatively 
        //$routeMatch = $e->getRouteMatch();
        //$action = $routeMatch->getParam('action', 'not-found');

        if(!method_exists(__Class__, $action."Action")){
           $this->noaction();
        }

        return parent::onDispatch($e);
    }
    public function noaction()
    {        
        echo 'action does not exits';   
    }
}
