Question

我有一个启用了调试的应用程序，转换为异常的错误和Monolog记录器服务：

ErrorHandler::register();
ExceptionHandler::register();

$app = new Silex\Application();

$logfile = dirname(__DIR__) . '/var/log/application.log';
$app->register(new Silex\Provider\MonologServiceProvider(), array(
    'monolog.logfile' => $logfile,
    'monolog.level' => Logger::DEBUG,    
));

我想将错误记录到文件中，详见浏览器。

示例：我访问了一个不存在的URL，我在浏览器中收到了下两个错误：

2/2
Not NotFoundHttpException in RouterListener.php line 159:
No route found for "GET /xxx"

1. in RouterListener.php line 159
2. at RouterListener->onKernelRequest(object(GetResponseEvent), 'kernel.request', object(EventDispatcher))
3. at call_user_func(array(object(RouterListener), 'onKernelRequest'), object(GetResponseEvent), 'kernel.request', object(EventDispatcher)) in EventDispatcher.php line 164
...

1/2
ResourceNotFoundException in UrlMatcher.php line 102:
No routes found for "/xxx".

1. in UrlMatcher.php line 102
2. at UrlMatcher->match('/xxx') in RedirectableUrlMatcher.php line 30
3. at RedirectableUrlMatcher->match('/xxx') in LazyUrlMatcher.php line 51
...

但是唯一记录的文字是：

[2016-03-30 21:32:10] myapp.ERROR: Symfony\Component\HttpKernel\Exception\NotFoundHttpException: No route found for "GET /xxx" (uncaught exception) at ...route.../vendor/symfony/http-kernel/EventListener/RouterListener.php line 159 {"exception":"[object] (Symfony\\Component\\HttpKernel\\Exception\\NotFoundHttpException(code: 0): No route found for \"GET /xxx\" at ...route.../vendor/symfony/http-kernel/EventListener/RouterListener.php:159, Symfony\\Component\\Routing\\Exception\\ResourceNotFoundException(code: 0): No routes found for \"/xxx\". at ...route.../vendor/symfony/routing/Matcher/UrlMatcher.php:102)"} []
[2016-03-30 21:32:10] myapp.INFO: < 404 [] []

有没有办法记录抛出的所有错误，包括完整的堆栈跟踪？

您可以编写将格式化错误的日志格式化程序

配置monolog：

$logfile = dirname(__DIR__) . '/var/log/application.log';
$app->register(new Silex\Provider\MonologServiceProvider(), array(
    'monolog.logfile' => $logfile,
    'monolog.level' => Logger::DEBUG,    
));

$app->extend('monolog', function($monolog, $app) {
    static $initialized = false;
    if ($initialized) return $monolog;
    $initialized = true;

    foreach ($monolog->getHandlers() as $handler)
        if ($handler->getFormatter() instanceof \Monolog\Formatter\LineFormatter)
            $handler->setFormatter(new \My\Formatter());

    return $monolog;
});

格式化：

class \My\Formatter extends \Monolog\Formatter\NormalizerFormatter
{
    public function format(array $record)
    {
        $output = ...;
        return $output
    }

    public function formatBatch(array $records)
    {
        $output = ...;
        return $output
    }
}

在Silex中使用Monolog记录错误时包含完整的堆栈跟踪
