Zend 框架 2 推荐的错误处理方式

问题描述

我注意到 Zend 提供的 Skeleton Application 不能处理 error 500.我知道在 ZF1 中有一个 ErrorController 来处理这个问题.我在网上做了一些研究，但没有找到明确的解决方案.

I noticed that the Skeleton Application that Zend provides does not handle error 500. I know that in ZF1 there was an ErrorController that took care of that. I have done some research online, but did not find a clear cut solution for this.

那么在 ZF2 中处理错误的最佳方法是什么?是基于每个模块还是某些全局异常/错误处理程序?

So what is the best way for error handling in ZF2. Would it be on per module basis or some global exception/error handler?

我知道另一种解决方案是将 ini_set('display_errors', true); 添加到我的 index.php 中，但我不太喜欢那个解决方案.框架似乎应该提供一些处理错误的方法.

I know that another solution would be to add ini_set('display_errors', true); to my index.php, but I don't really like that solution. It seems that the framework should provide some way for handling errors.

推荐答案

您可以在捕获异常后以任何方式处理异常，例如以下示例，其中全局捕获异常...:

You can handle the exceptions in anyway you want after catching it as the following example in which you are catching the exception globally...:

在你的Module.php中的onBootstrap方法中，你可以附加一个在事件发生时执行的函数，下面附加一个在发生错误时执行的函数(异常)引发:

In the onBootstrap method in your Module.php you can attach a function to execute when an event occurs, the following attach a function to be executed when an error (exception) is raised:

public function onBootstrap(MvcEvent $e)
{
    $application = $e->getApplication();
    $em = $application->getEventManager();
    //handle the dispatch error (exception) 
    $em->attach(endMvcMvcEvent::EVENT_DISPATCH_ERROR, array($this, 'handleError'));
    //handle the view render error (exception) 
    $em->attach(endMvcMvcEvent::EVENT_RENDER_ERROR, array($this, 'handleError'));
}

然后定义函数以任何你想要的方式处理错误，下面是一个例子:

and then define the function to handle the error in any way you want, the following is an example:

public function handleError(MvcEvent $e)
{
    //get the exception
    $exception = $e->getParam('exception');
    //...handle the exception... maybe log it and redirect to another page, 
    //or send an email that an exception occurred...
}
