symfony2给出内部服务器错误，没有日志

Question

I am trying to setup Symfony2 into an existing project, so I am setting everything up from scratch. I keep getting "500 Internal Server Error" inside Symfony2. There are no logs inside web server logs and Symfony2 does not even create a log file inside the the logs directory (I set it up as ROOT/var/logs using AppKernel). Here is my configuration:

parameters:
    app_locales: en|fr|de|es|cs|nl|ru|uk|ro|pt_BR|pl|it|ja|id|ca
    app.notifications.email_sender: [e-mail]
    locale: en
    secret: "MaEKo3wZsCMIz7tR1uBCyIDGhvJU0EbnYgl0YlhognA"

framework:
    ide: sublime

translator:      { fallback: "%locale%" }
secret:          "%secret%"
router:
    resource: "%kernel.root_dir%/config/routes.yml"
    strict_requirements: ~
form:            ~
csrf_protection: ~
validation:      { enable_annotations: true }
templating:
    engines: ['twig']
default_locale:  "%locale%"
trusted_hosts:   ~
trusted_proxies: ~
session:
    handler_id:  ~
fragments:       ~
http_method_override: true

twig:
    debug:            "%kernel.debug%"
    strict_variables: "%kernel.debug%"


# routes.yml

homepage:
    path: /
    defaults:
        _controller: FrameworkBundle:Controller:template
        template:    default/homepage.html.twig

And here is AppKernel.php:

class AppKernel extends Kernel {

    public function registerBundles() {
        return [
            new Symfony\Bundle\FrameworkBundle\FrameworkBundle,
            new Symfony\Bundle\SecurityBundle\SecurityBundle,
            new Symfony\Bundle\TwigBundle\TwigBundle,
            new Symfony\Bundle\DebugBundle\DebugBundle,
            new Symfony\Bundle\WebProfilerBundle\WebProfilerBundle
        ];
    }

    public function getCacheDir() {
        return $this->rootDir.'/../var/cache';
    }

    public function getLogDir() {
        return $this->rootDir.'/../var/logs';
    }

    public function registerContainerConfiguration(LoaderInterface $loader) {
        $loader->load(__DIR__.'/config/config.yml');
    }

}

What am I missing here?

Answer 1

I dug in Symfony2 source code and found that it was catching the exception before I was sending it. So, for debugging purposes, I changed my handling code to:

$response = $kernel->handle($request, HttpKernelInterface::MASTER_REQUEST, false );
