2.4 Expression Language Request Stack

Expression Language https://secure.flickr.com/photos/sergiu_bacioiu/3930657923

foo.bar foo.getBar() foo['bar']

$language = new ExpressionLanguage(); echo $language->evaluate('1 + 1'); // will echo 2 echo $language->compile('1 + 2'); // will echo "(1 + 2)"

not foo or bar foo in ['foo', 'bar'] foo ? true : false foo matches "/^foo/i"

The Request Stack https://secure.flickr.com/photos/kemped/3705729840

What is a scope? What is a strict service? What is a synchronized service?

Master Request {{ render(controller('a:b:c')) }} Sub-Request

Request Response response Call Controller response? expection Sub-Request terminate controller view resolve controller resolve arguments request exception “sub-response” content

Call Controller Request Response response response? expection Sub-Request terminate controller view resolve controller resolve arguments request exception “sub-response” content

class FooService { public function __construct(Request $request) { $this->request = $request; } public function doSomething() { $this->request->...(); } }

class FooService { public function __construct(ContainerInterface $container) { $this->container = $container; } public function doSomething() { $this->container->get('request')->...(); } }

Inject the dependencies Not the Container Pro Tip #1

Scopes Strict services Synchronized services

How can I depend on the Request in my services?

use Symfony\Component\HttpFoundation\RequestStack; class FooService { public function __construct(RequestStack $requestStack) { $this->requestStack = $requestStack; } public function doSomething() { $this->requestStack->getCurrentRequest()->...(); } }

$requestStack->getCurrentRequest()

class FooController { public function indexAction(Request $request) { $request->...(); } } class FooListener { public function onKernelRequest(GetResponseEvent $event) { $event->getRequest()->...(); } }

Inject the Request Stack Not the Request Pro Tip #2
