# 본문 - 다중 매개변수

지금부터 `Path`와 `Query`를 어떻게 사용하는지 확인하겠습니다.

요청 본문 선언에 대한 심화 사용법을 알아보겠습니다.

## `Path`, `Query` 및 본문 매개변수 혼합

당연하게 `Path`, `Query` 및 요청 본문 매개변수 선언을 자유롭게 혼합해서 사용할 수 있고, **FastAPI**는 어떤 동작을 할지 압니다.

또한, 기본 값을 `None`으로 설정해 본문 매개변수를 선택사항으로 선언할 수 있습니다.

{* ../../docs_src/body_multiple_params/tutorial001.py hl[19:21] *}

/// note | 참고

이 경우에는 본문으로 부터 가져온 `	item`은 기본값이 `None`이기 때문에, 선택사항이라는 점을 유의해야 합니다.

Note que neste caso, nós estamos declarando o parâmetro de path ao lado do parâmetro da requisição.

Assim, o parâmetro de path será extraído, validado, convertido para o tipo especificado e anotado com OpenAPI.

Do mesmo jeito, você pode declarar qualquer outro parâmetro normalmente, e além disso, obter o `Request` também.

src/cmd/go.mod. When a package outside std or cmd is imported
by a package inside std or cmd, the import path is interpreted
as if it had a "vendor/" prefix. For example, within "crypto/tls",
an import of "golang.org/x/crypto/cryptobyte" resolves to
"vendor/golang.org/x/crypto/cryptobyte". When a package with the
same path is imported from a package outside std or cmd, it will
be resolved normally. Consequently, a binary may be built with two
