从 module.php 转发到另一个控制器/动作 [英] Forward to another controller/action from module.php

问题描述

我正在为 ZF2 中的 ACL 编写一个模块，我几乎完成了.

我遇到的问题是当用户无权访问请求的页面时，我想转发用户到显示403消息的页面.

我已经尝试将用户重定向到403，但它更新了URL，所以现在我正在尝试转发用户.

我想要做的就是从 Module.php.我试过下面的代码 -

Module.php

if (!$isAllowed) {$e->getApplication()->getServiceManager()->get('ControllerPluginManager')->get('forward')->dispatch('acl');}

使用这个我得到以下错误 -

<块引用>

未捕获的异常Zend\Mvc\Exception\DomainException"，消息为转发插件需要一个实现 InjectApplicationEventInterface 的控制器"

我也尝试使用 InjectApplicationEventInterface 来实现 Acl 控制器，但问题仍然存在.

你能解释一下如何从 Module.phpForward 到另一个 Action 吗?
如果您需要更多详细信息，请告诉我.

解决方案

你可以做的是监听 dispatch 事件.您可以在此事件期间更新路由匹配以匹配您自己定义的用于呈现 403 页面的控制器/操作对.

在代码中:

使用MvcEvent；类模块{公共函数 onBootstrap($e){$app = $e->getApplication();$acl = $app->getServiceManager()->get('ACL');//在此处获取您的 ACL如果 (!$acl->isAllowed()) {$em = $app->getEventManager();$em->attach(MvcEvent::EVENT_DISPATCH, function($e) {$routeMatch = $e->getRouteMatch();$routeMatch->setParam('controller', 'my-403-controller');$routeMatch->setParam('action', 'my-403-action');}, 1000);}}}

转发是一种当另一个控制器已经被分派时分派一个控制器的模式.这不是你的情况，因为我是从你的问题中读到的.所以不要使用forward插件，而是在调度之前修改路由匹配.

I am writing a module for ACL in ZF2, And I am almost done with it.

The point where I am stucked is when user is not authorised to access the requested page, I want to forward the user to a page showing 403 message.

I have tried redirecting user to 403 but it updates URL, so now I am tring to forward user.

All I want to do is from Module.php. I have tried below code -

Module.php

if (!$isAllowed) {
    $e->getApplication()->getServiceManager()->get('ControllerPluginManager')->get('forward')->dispatch('acl');
}

Using this I got following error -

Uncaught exception 'Zend\Mvc\Exception\DomainException' with message 'Forward plugin requires a controller that implements InjectApplicationEventInterface'

I have also tried to implement Acl controller with InjectApplicationEventInterface, But the issue remains same.

Can you please explain how to Forward to another Action from Module.php?
Let me know if you need more details.

解决方案

What you can do is to listen for the dispatch event. You can update the route match during this event to match a controller/action pair which is defined by yourself to render the 403 page.

In code:

use MvcEvent;

class Module
{
    public function onBootstrap($e)
    {
        $app = $e->getApplication();
        $acl = $app->getServiceManager()->get('ACL'); // get your ACL here

        if (!$acl->isAllowed()) {
            $em = $app->getEventManager();
            $em->attach(MvcEvent::EVENT_DISPATCH, function($e) {
                $routeMatch = $e->getRouteMatch();

                $routeMatch->setParam('controller', 'my-403-controller');
                $routeMatch->setParam('action', 'my-403-action');
            }, 1000);
        }
    }
}

Forwarding is a pattern to dispatch a controller when another controller has already been dispatched. That is not your case, as I read it from your question. So don't use the forward plugin, but modify the route match before it's dispached.
