Silex 异常处理程序 [英] Silex Exception handler

问题描述

我有一个大问题，我不知道为什么 silex 异常处理程序没有捕获异常?

I have big problem I don't know why exceptions are not catch by silex exception handler ?

我的简单代码如下所示:

My simple Code looks like this:

<?php

use Silex\Application;

use Silex\Provider\ValidatorServiceProvider;
use Silex\Provider\FormServiceProvider;
use Symfony\Component\HttpFoundation\Request;

$app = new Application();

// SPL Logic Exceptions
// Handle other exception as 500 errors
$app->error(function (\Exception $e, $code) {
exit('asd');
});
throw new Exception('test');
return $app;

结果是:

致命错误:未捕获的异常异常"，消息为测试"

推荐答案

error 侦听器只能捕获从控制器或 before 中间件中抛出的异常.这是一个有效的例子:

The error listener is only able to catch exceptions thrown from within a controller or a before middleware. Here's an example that works:

$app = new Silex\Application();

$app->error(function (\Exception $e, $code) {
    exit('asd');
});

$app->before(function ($request) {
    throw new Exception('test');
});

$app->run();
