How to get controller and action name in zf2
提问by Developer
in zf1, we can get controller and action name using
在 zf1 中，我们可以使用
$controller = $this->getRequest()->getControllerName();
$action = $this->getRequest()->getActionName();
How we can achieve this in zf2?
我们如何在 zf2 中实现这一目标？
UPDATE: I tried to get them using
更新：我试图让他们使用
echo $this->getEvent()->getRouteMatch()->getParam('action', 'NA');
echo $this->getEvent()->getRouteMatch()->getParam('controller', 'NA');
But I am getting error
但我收到错误
Fatal error: Call to a member function getParam() on a non-object
I like to get them in __construct() method;
我喜欢在 __construct() 方法中获取它们；
Ideally I would like to check if there is no Action is defined it will execute noaction() method. I would check using php method method_exists.
理想情况下，我想检查是否没有定义 Action 它将执行 noaction() 方法。我会检查使用 php 方法 method_exists。

you can't access these variables in controller __construct()method, but you can access them in dispatchmethod and onDispatchmethod.
你不能在控制器__construct()方法中访问这些变量，但你可以在dispatch方法和onDispatch方法中访问它们。
but if you would like to check whether action exist or not, in zf2 there is already a built in function for that notFoundAction as below
但是如果你想检查动作是否存在，在 zf2 中已经有一个内置函数用于 notFoundAction 如下
public function notFoundAction()
{
parent::notFoundAction();
$response = $this->getResponse();
$response->setStatusCode(200);
$response->setContent("Action not found");
return $response;
}
but if you still like to do it manually you can do this using dispatch methods as follow
但是如果您仍然喜欢手动执行此操作，则可以使用如下调度方法执行此操作
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';
}
}

Even simpler:
更简单：
$controllerName =$this->params('controller');
$actionName = $this->params('action');

You will get module , controller and action name like this in Zf2 inside your controller...
您将在控制器内的 Zf2 中获得这样的模块、控制器和动作名称...
$controllerClass = get_class($this);
$moduleNamespace = substr($controllerClass, 0, strpos($controllerClass, '\'));
$tmp = substr($controllerClass, strrpos($controllerClass, '\')+1 );
$controllerName = str_replace('Controller', "", $tmp);
//set 'variable' into layout...
$this->layout()->currentModuleName = strtolower($moduleNamespace);
$this->layout()->currentControllerName = strtolower($controllerName);
$this->layout()->currentActionName = $this->params('action');
回答by Piter
$controllerName = strtolower(Zend_Controller_Front::getInstance()->getRequest()->getControllerName());
