Interceptorlar

regular interceptors va web sockets interceptorlari o'rtasida farq yo'q. Quyidagi misolda qo'lda instansiyalangan method-scoped interceptor ishlatiladi. HTTP asosidagi ilovalar kabi, gateway-scoped interceptorlardan ham foydalanishingiz mumkin (ya'ni, gateway klassiga @UseInterceptors() dekoratorini qo'shing).
