如何记录ZF2控制器异常

问题描述

我正在注册一个用于异常的Zend\Log实例,我将最终通过电子邮件发送所有系统错误,现在它只是一个文件。但是,它在控制器中不起作用,异常会在视图中显示(或不是,取决于 display_exceptions )。我发现这个,没有人似乎很在乎。所以我需要一个解决方法。有没有办法使控制器不要吃我的例外?

 'service_manager'=>数组(
'工厂'=>数组(
'Logger'=>函数($ sm)use($ sRootDir)
{
$ log = new Zend\ Log\Logger();
$ writer = new Zend\Log\Writer\Stream($ sRootDir。'/temp/license.log');
$ log-> addWriter $ writer
Zend\Log\Logger :: registerErrorHandler($ log);
Zend\Log\Logger :: registerExceptionHandler($ log);
return $ log;
},
),


解决方案

您可以附加到发送错误事件:



Module.php {
$ eventManager = $ e-> getApplication()

$ - > getEventManager();
$ moduleRouteListener = new ModuleRouteListener();
$ moduleRouteListener-> attach($ eventManager);
/ **
*记录任何未捕获的错误
* /
$ sharedManager = $ e-> getApplication() - > getEventManager() - > getSharedManager();
$ sm = $ e-> getApplication() - > getServiceManager();
$ sharedManager-> attach('Zend\Mvc\Application','dispatch.error',
function($ e)use($ sm){
if($ e - > getParam('exception')){
$ sm-> get('Logger') - > crit($ e-> getParam('exception'));
}
}
);
}

简单记录器的示例服务配置

 '工厂'=> array(
'Logger'=> function($ sm){
$ logger = new \Zend\Log\Logger;
$ writer = new \Zend\Log \Writer\Stream('./ data / log /'。date('Ym-d').'- error.log');
$ logger-> addWriter($ writer);
return $ logger;
},
// ...
);

您还可以记录堆栈中的所有异常,以更好地了解出现的错误,而不是只显示最后一个例外,可能不包含很多信息。

  public function onBootstrap(MvcEvent $ e)
{
$ eventManager = $ e-> getApplication() - > getEventManager();
$ moduleRouteListener = new ModuleRouteListener();
$ moduleRouteListener-> attach($ eventManager);
/ **
*记录任何未捕获的异常,包括堆栈中的所有异常
* /
$ sharedManager = $ e-> getApplication() - > getEventManager() - > getSharedManager();
$ sm = $ e-> getApplication() - > getServiceManager();
$ sharedManager-> attach('Zend\Mvc\Application','dispatch.error',
function($ e)use($ sm){
if($ e - > getParam('exception')){
$ ex = $ e-> getParam('exception');
do {
$ sm-> get('Logger' ) - > crit(
sprintf(
%s:%d%s(%d)[%s] \\\

$ ex-> getFile()
$ ex-> getLine(),
$ ex-> getMessage(),
$ ex-> getCode(),
get_class($ ex)

);
}
while($ ex = $ ex-> getPrevious());
}
}
);
}


I'm registering a Zend\Log instance for exceptions, I will need all system errors emailed in the end, now it's just goes to a file. However, it doesn't work in controllers, the exception gets displayed in the view (or not, depending on display_exceptions). I found this bug, no one seems to care about it much. So I need a workaround. Is there a way to make controllers not to eat my exceptions?

'service_manager' => array(
    'factories' => array(
        'Logger' => function ($sm) use ($sRootDir)
            {
            $log = new Zend\Log\Logger();
            $writer = new Zend\Log\Writer\Stream($sRootDir . '/temp/license.log');
            $log->addWriter($writer);
            Zend\Log\Logger::registerErrorHandler($log);
            Zend\Log\Logger::registerExceptionHandler($log);
            return $log;
            },
    ),
解决方案

You can attach to the dispatch error event:

Module.php

public function onBootstrap(MvcEvent $e)
{
    $eventManager = $e->getApplication()->getEventManager();
    $moduleRouteListener = new ModuleRouteListener();
    $moduleRouteListener->attach($eventManager);
    /**
     * Log any Uncaught Errors
     */
    $sharedManager = $e->getApplication()->getEventManager()->getSharedManager();
    $sm = $e->getApplication()->getServiceManager();
    $sharedManager->attach('Zend\Mvc\Application', 'dispatch.error',
         function($e) use ($sm) {
            if ($e->getParam('exception')){
                $sm->get('Logger')->crit($e->getParam('exception'));
            }
         }
    );
}

An example service config for a simple logger

'factories' => array(
    'Logger' => function($sm){
        $logger = new \Zend\Log\Logger;
        $writer = new \Zend\Log\Writer\Stream('./data/log/'.date('Y-m-d').'-error.log');
        $logger->addWriter($writer);
        return $logger;
    },
    // ...
);

You can also log all exceptions in the stack to get a better idea of what went wrong down the line, rather than only showing the last exception, which may not include much information.

public function onBootstrap(MvcEvent $e)
{
    $eventManager = $e->getApplication()->getEventManager();
    $moduleRouteListener = new ModuleRouteListener();
    $moduleRouteListener->attach($eventManager);
    /**
     * Log any Uncaught Exceptions, including all Exceptions in the stack
     */
    $sharedManager = $e->getApplication()->getEventManager()->getSharedManager();
    $sm = $e->getApplication()->getServiceManager();
    $sharedManager->attach('Zend\Mvc\Application', 'dispatch.error',
        function($e) use ($sm) {
            if ($e->getParam('exception')){
                $ex = $e->getParam('exception');
                do {
                    $sm->get('Logger')->crit(
                        sprintf(
                           "%s:%d %s (%d) [%s]\n",
                            $ex->getFile(),
                            $ex->getLine(),
                            $ex->getMessage(),
                            $ex->getCode(),
                            get_class($ex)
                        )
                    );
                }
                while($ex = $ex->getPrevious());
            }
        }
    );
}
