`Field`는 `Query`, `Path`와 `Body`와 같은 방식으로 동작하며, 모두 같은 매개변수들 등을 가집니다.

/// note | "기술적 세부사항"

실제로 `Query`, `Path`등, 여러분이 앞으로 볼 다른 것들은 공통 클래스인 `Param` 클래스의 서브클래스 객체를 만드는데, 그 자체로 Pydantic의 `FieldInfo` 클래스의 서브클래스입니다.

그리고 Pydantic의 `Field` 또한 `FieldInfo`의 인스턴스를 반환합니다.

Aqui nós usamos para criar um `GzipRequest` a partir da requisição original.

```Python hl_lines="18-26"

```

/// note | Detalhes Técnicos

Um `Request` também tem um `request.receive`, que é uma função para "receber" o corpo da requisição.
