php - How to receive GET request from external source with CakePHP -

i'm working on project allows external users(coming source server) make request page on server, return json encoded data.

for example, data (not using cake, standard php) sent

wwww.example.com/handlerequest.php 

i'd have like

if(isset($_get['userrequest'])){     //do stuff     echo $json_encoded_stuff; } 

with cakephp i'd post data like

www.example.com/handlerequest 

however, do not want/need view because there nothing see. page purely data exchange. considering this, there special have cake doesn't throw error because it's expecting corresponding view? possible?

it easy disable both layout , view in cakephp putting following line in controller action:

$this->autorender = false; 

if want disable layout, use following line in controller action:

$this->layout = false; 

and if want disable view action, use following line in controller:

$this->render(false); 

note using $this->layout = false; , $this->render(false); in controller action give same results $this->autorender = false;
