Exemple d’un squelette d’API REST avec Zend Framework.

Plugin d’authentification :

class RestAuth extends Zend_Controller_Plugin_Abstract
{
    public function preDispatch(Zend_Controller_Request_Abstract $request)
    {
        $apiKey = $request->getHeader('apikey');

        if ($apiKey != 'secretKey') {
            $this->getResponse()
                 ->setHttpResponseCode(403)
                 ->appendBody('Clef API invalide');

            $request->setModuleName('default')
                    ->setControllerName('error')
                    ->setActionName('access')
                    ->setDispatched(true);
        }
    }
}

Le controller principal qui va gérer l’utilisation de l’API pour les articles :

class ArticleController extends Zend_Rest_Controller
{
    public function init()
    {
        $this->_helper->viewRenderer->setNoRender(true);
    }

    public function indexAction()
    {
         $this->getResponse()
              ->setHttpResponseCode(200)
              ->appendBody('Tous les articles');
    }

    public function getAction()
    {
        $this->getResponse()
             ->setHttpResponseCode(404)
             ->appendBody('Article n°5');
    }

    public function postAction()
    {
        $this->getResponse()
             ->setHttpResponseCode(201)
             ->appendBody('Article créé');
    }

    public function putAction()
    {
        $this->getResponse()
             ->setHttpResponseCode(503)
             ->appendBody('Article remplacé');
    }

    public function deleteAction()
    {
        $this->getResponse()
             ->setHttpResponseCode(204);
    }
}
