Ako ziskat JSON parametre?

Mam nasledujuci kod:

if ($this->isAjax()) {

			//Neviem, ako ziskat JSON parametre, parametre chcem pouzit dalej do metody getStatuses ale neviem, ako ich ziskat. Odosielane su POSTom;
			?? $this->getPayload(); ??

            $model = new Model\StatusModel($this->context);
            $statuses = $model->getStatuses();
            foreach ($statuses as $status) {
                $this->payload->data[] = $status->toArray();
            }
            $this->payload->total = $model->getStatuses()->count();
            $this->sendPayload();
        }

Neviem, ako ziskat parametre z JSONu.
