En resumen
1. Se carga un array de ~1.500 elementos.
2. Se crea un objeto SilexApplication.
3. Se ejecuta el register() de todos los servicios.
4. Se crea un objeto Request.
5. Se ejecuta el boot() de todos los servicios.
6. Se crea un objeto Response (con tu controlador).
7. Se envía la respuesta al usuario.
8. Se ejecuta el terminate() de la aplicación.

Ventajas de reutilizar aplicaciones
• Sólo se aplica la seguridad en la
aplicación backend.
• El rendimiento de la parte pública no
se ve afectado.
• En el backend están disponibles todas
las rutas y controladores públicos.

MIDDLEWARES

Middlewares de aplicación
$app->before(function ($request) {
// ...
});
$app->after(function ($request, $response) {
// ...
});
$app->finish(function ($request, $response) {
// ...
});

Middlewares de controlador
$before = function ($request) use ($app) {
// ...
};
$after = function ($request, $response) use ($app) {
// ...
};
$app->get('...', function () {
// ...
})
->before($before)
->after($after);

El middleware before()
public function before($callback, $priority = 0)
{
$this->on(
KernelEvents::REQUEST,
function ($event) use ($callback) {
$ret = call_user_func($callback, $event->getRequest());
if ($ret instanceof Response) {
$event->setResponse($ret);
}
},
$priority
);
}

El middleware before()
public function before($callback, $priority = 0)
{
$this->on(
KernelEvents::REQUEST,
function ($event) use ($callback) {
$ret = call_user_func($callback, $event->getRequest());
if ($ret instanceof Response) {
$event->setResponse($ret);
}
},
$priority
);
}
public function on($eventName, $callback, $priority = 0)
{
// ...
$dispatcher->addListener($eventName, $callback, $priority);
}

Middlewares «obligatorios»
$app->before(function() use ($app) {
if (!$app['security']->isGranted('ROLE_ADMIN')) {
return $app->redirect('/');
}
});

Middlewares «prescindibles»
$app->before(function(Request $request) {
$request->query->set('token', '...');
$request->server->set('SERVER_ADDR', '::1');
});

Mismo ejemplo sin middlewares
require_once __DIR__.'/../vendor/autoload.php';
$app = new SilexApplication();
$app->register( ... );
$app->get('/', function() use($app) {
return $app['twig']->render('portada.twig'),
});
$app->run();

Mismo ejemplo sin middlewares
require_once __DIR__.'/../vendor/autoload.php';
$app = new SilexApplication();
$app->register( ... );
$app->get('/', function() use($app) {
return $app['twig']->render('portada.twig'),
});
$app->run();
public function run(Request $request = null)
{
if (null === $request) {
$request = Request::createFromGlobals();
}
// ...
}

Mismo ejemplo sin middlewares
require_once __DIR__.'/../vendor/autoload.php';
$app = new SilexApplication();
$app->register( ... );
$app->get('/', function() use($app) {
return $app['twig']->render('portada.twig'),
});
$request = Request::createFromGlobals();
$request->query->set('token', '...');
$request->server->set('SERVER_ADDR', '::1');
$app->run($request);

Middlewares «prescindibles»
$app->before(function() use ($app) {
$app['time.start'] = microtime(true);
});
$app->after(function() use ($app) {
$app['time.end'] = microtime(true);
});
$app->finish(function() use ($app) {
$elapsed = $app['time.start'] - $app['time.end'];
$app['monolog']->addDebug(...);
});

Mismo ejemplo «sin middlewares»
$app->finish(function(Request $request) use ($app) {
$elapsed = 1000 * (
microtime(true) - $request->server->get('REQUEST_TIME_FLOAT')
);
$app['monolog']->addDebug(...);
});

SILEX 1.1

Silex 1.0
public function before($callback, $priority = 0)
{
$this['dispatcher']->addListener(
KernelEvents::REQUEST,
function (GetResponseEvent $event) use ($callback) {
// ...
}
Los métodos on(), before(), after(), error() fuerzan la
creación del dispatcher y todas sus dependencias.

Lazy dispatcher
public function before($callback, $priority = 0)
{
$this['dispatcher'] = $this->share($this->extend('dispatcher',
function ($dispatcher, $app) use ($callback, $priority) {
$dispatcher->addListener(
KernelEvents::REQUEST, $callback, $priority
);
return $dispatcher;
}));
}
En Silex 1.1, los métodos on(), before(), after(),
error() crean el dispatcher en el último momento.
