如何从ZF2模块中的Route获取参数?(类模块，函数 onBootstrap())

问题描述

在控制器中，我可以使用 $this->params()->fromRoute('param1')
我如何在 Module OnBootstrap() 函数中做到这一点?

In controller I can get parameters from route using $this->params()->fromRoute('param1')
How can I do that in Module OnBootstrap() function?

namespace MyModule;

use Zend\EventManager\EventInterface;

class Module
{
    public function onBootstrap(EventInterface $event)
    {
        // here I need to get parameter from route
    }
}

推荐答案

正如 user2257808 在他的评论中所说，onBootstrap 在路由发生之前被调用，因此没有任何 RouteMatch 可以获取.他建议附加到 EVENT_RENDER，这对您来说可能为时已晚.

As user2257808 said in his comment, onBootstrap is called before routing takes place, so there is not any RouteMatch to get. He suggested attaching to EVENT_RENDER, that may be too late in your case.

我会做这样的事情，附加到 MvcEvent::EVENT_DISPATCH.

I would do something like this, attaching to MvcEvent::EVENT_DISPATCH.

MyModule\Module.php

class Module {
    public function onBootstrap(MvcEvent $e) {

        $e->getApplication()->getEventManager()->attach(MvcEvent::EVENT_DISPATCH,
            function($e){
               var_dump($e->getRouteMatch());
                exit;
            }
         );

    }
}
