PHP-ZF3 / 2-如何捕获在EVENT_DISPATCH侦听器中引发的异常？

有什么方法可以处理EVENT_DISPATCH侦听器中引发的异常？

class Module
{
    public function onBootstrap(EventInterface $event)
    {
        $application    = $event->getTarget();
        $eventManager   = $application->getEventManager();

        $eventManager->attach(MvcEvent::EVENT_DISPATCH, function(MvcEvent $event) {
            throw new ForbiddenException("403 - Fobidden");
        });
    }
}

我有一种常见的服务ForbiddenException的方式,例如设置403,返回JSON等.所有逻辑都附加到MvcEvent :: EVENT_DISPATCH_ERROR侦听器.如何将ForbiddenException传输到调度错误侦听器内的侦听器？将其从调度侦听器中抛出会导致未捕获的异常错误…

任何帮助或技巧如何克服它,将不胜感激！

解决方法:

您应该使用sharedevent管理器来绑定事件.像这样 ：

public function onBootstrap(MvcEvent $e)
{
    $eventManager = $e->getApplication()->getEventManager();
    $moduleRouteListener = new ModuleRouteListener();
    $moduleRouteListener->attach($eventManager);

    $sharedManager = $e->getApplication()->getEventManager()->getSharedManager();
    $sm = $e->getApplication()->getServiceManager();
    $sharedManager->attach(
         'Zend\Mvc\Application', 
         'dispatch.error',
         function($e) use ($sm) {
            //Do what you want here
         }
    );
}

我建议一旦这样工作,就将匿名函数替换为可调用类.
