如何在ZF2控制器中捕获异常？ [英] How to catch exceptions in your ZF2 controllers?

问题描述

我已经使用 ZF 2.0.3 ZendSkeletonApplication c $ c>我无法在控制器中捕获异常。例如，如果我将以下代码放在 module / Application / src / Application / Controller / IndexController.php 中：

public function indexAction（）{
echoBEFORE\\\
;

  
 try {
 throw new \Exception（我的异常）; 
} catch（异常$ e）{
 echo捕获异常$ e\\\
; 
退出; 
} 
  

并访问我获得的页面：

  BEFORE 
发生错误
执行期间发生错误;请稍后再试。 
附加信息：
异常
 
文件：
 
模块/应用程序/ src /应用程序/控制器/ IndexController.php：25 
 
消息：
 
我的例外
  

ViewModel 启动并显示异常，有效阻止我捕获它。

如何捕获<$ c中的异常$ c> ZF2 控制器？

解决方案

您正在扔PHP的通用异常

  throw new \Exception（我的异常）; 
  

但是您从当前命名空间捕获异常

 } catch（Exception $ e）{
  

假设您的控制器位于 Application\Controller 中，您必须声明

 使用\Exception; 
  

您的课程以上将全局异常导入当前命名空间或

  
 
I've setup the ZendSkeletonApplication with ZF 2.0.3 and I am unable to catch exceptions in my controllers. For instance if I put the below piece of code in module/Application/src/Application/Controller/IndexController.php:
public function indexAction() {
    echo "BEFORE\n";
    try {
        throw new \Exception("My exception");
    } catch (Exception $e) {
        echo "Caught exception $e\n";
        exit;
    }
and access the page I get:
BEFORE
An error occurred
An error occurred during execution; please try again later.
Additional information:
Exception

File:

    module/Application/src/Application/Controller/IndexController.php:25

Message:

    My exception
the ViewModel kicks in and displays the exception, effectively preventing me from catching it.

How can I catch exceptions in ZF2 controllers?
解决方案
You are throwing PHP's generic Exception 
throw new \Exception("My exception");
but you catch the Exception from the current namespace
} catch (Exception $e) {
Assuming your controller is in Application\Controller, you either have to declare
use \Exception;
above your class to import the global Exception into the current namespace or
} catch (\Exception $e) {
to catch PHP's global Exception.
