Symfony2 get current environment in response listener
symfony
Solution
$event->getKernel() returns an object which implements HttpKernelInterface. Whereas Kernel or `AppKernel` implements KernelInterface which have `getEnvironment` method. You have to inject `@kernel` service in your listener.
Problem
I'd like to know if I'm using app_dev.php from within a listener (set up as a service in `config.yml`). It fails at getEnvironment() though this is the method I use in the controller. ``` public function onKernelResponse(FilterResponseEvent $event) { $kernel = $event->getKernel(); $this->isAppDev = ($kernel->getEnvironment() == "dev") ? true : false; } ``` Edit Solution: In my listener class: ``` use Symfony\Component\HttpFoundation\Response; use Symfony\Component\HttpKernel\Event\FilterResponseEvent; use Symfony\Component\HttpKernel\Kernel; private $kernel; public function __construct(Kernel $kernel) { $this->kernel = $kernel } public function onKernelResponse(FilterResponseEvent $event) { $this->isAppDev = ($this->kernel->getEnvironment() == "dev") ? true : false; } ``` At the bottom of config.yml: ``` services: my.listener: class: Path\To\Listener tags: - { name: kernel.event_listener, event: kernel.response } arguments: [@kernel] ```
