php - Decorate or extend HTTP request class in Silex -

in example, want add additional methods request class, getrequiered*($name) throw exception in case of missed param in request. i'd implement this:

class mysmartrequest extends request {     // ...     function getintrequired($name) {         $res = $this->get($name, null);         if (null === $res) { throw new exception('missed required param'); }         return (int) $res;     } }  // ...  $app->before(function(request $r) {     return new mysmartrequest($r); }); 

is possilbe?

yes, possible (never done this, following tip reading code).

you'll need create subclass of silex\application, , overwrite run() function this:

public function run(request $request = null) {     if (null === $request) {         $request = mysmartrequest::createfromglobals();     }      $response = $this->handle($request);     $response->send();     $this->terminate($request, $response); } 

to avoid duplication, can try this:

public function run(request $request = null) {     if (null === $request) {         $request = mysmartrequest::createfromglobals();     }      parent::run($request);  }
