Interceptorlar

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