Bu basit durum FastAPI tarafından otomatik olarak ele alınır; çünkü dönüş tipi annotation’ı `Response` class’ıdır (veya onun bir subclass’ı).

Araçlar da memnun olur; çünkü hem `RedirectResponse` hem `JSONResponse`, `Response`’un subclass’ıdır. Yani type annotation doğrudur.

### Bir Response Subclass’ını Annotate Etmek { #annotate-a-response-subclass }

Type annotation içinde `Response`’un bir subclass’ını da kullanabilirsiniz:

## Retornando uma `Response` { #return-a-response }

Você pode retornar uma `Response` ou qualquer subclasse dela.

/// info | Informação

A própria `JSONResponse` é uma subclasse de `Response`.

///

E quando você retorna uma `Response`, o **FastAPI** vai repassá-la diretamente.
