Nuevas funcionalidades rest client

Añadimos esto en la vista index:

 <li><?php echo $this->Html->link('Ver producto con ID 1', array('controller' => 'cliente', 'action' => 'rest_view', 1)); ?></li>
<li><?php echo $this->Html->link('Añadir producto', array('controller' => 'cliente', 'action' => 'rest_add')); ?></li>
<li><?php echo $this->Html->link('Actualizar producto 2', array('controller' => 'cliente', 'action' => 'rest_edit', 2)); ?></li>
<li><?php echo $this->Html->link('Borrar producto 3', array('controller' => 'cliente', 'action' => 'rest_delete', 3)); ?></li>

Y esto en el controlador:

  public function rest_view($id){
 
 $link = $this->url.'rest_productos/'.$id.'.json';
 
 $data = null;
 $httpSocket = new HttpSocket();
 $response = $httpSocket->get($link, $data );
 $this->set('response_code', $response->code);
 $this->set('response_body', $response->body);
 
 $this -> render('/Cliente/respuesta');
 }

 public function rest_add(){
 
$link=$this->url."rest_productos.json";
 $data = null;
 $httpSocket = new HttpSocket();
 $data['Producto']['nombre'] = 'Nuevo producto';
 $data['Producto']['referencia'] = 'Nueva referencia';
 //$data['Phone']['name'] = 'New Phone Description';
 $response = $httpSocket->post($link, $data );
 $this->set('response_code', $response->code);
 $this->set('response_body', $response->body);
 
 $this -> render('/Cliente/respuesta');
 }
 public function rest_edit($id){
 
 $link = $this->url.'rest_productos/'.$id.'.json';
 $data = null;
 $httpSocket = new HttpSocket();
 $data['Producto']['nombre'] = 'Actualizado producto';
 $data['Producto']['referencia'] = 'Actualizada referencia';
 $response = $httpSocket->put($link, $data );
 $this->set('response_code', $response->code);
 $this->set('response_body', $response->body);
 
 $this -> render('/Cliente/respuesta');
 }
 
 public function rest_delete($id){
 
 // remotely post the information to the server
 $link = $this->url.'rest_productos/'.$id.'.json';
 $data = null;
 $httpSocket = new HttpSocket();
 $response = $httpSocket->delete($link, $data );
 $this->set('response_code', $response->code);
 $this->set('response_body', $response->body);
 
 $this -> render('/Cliente/respuesta');
 }
