/// note | Nota

FastAPI sabrá que el valor de `q` no es requerido debido al valor por defecto `= None`.

El `str | None` no es utilizado por FastAPI para determinar que el valor no es requerido, sabrá que no es requerido porque tiene un valor por defecto de `= None`.

먼저, 물론 `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_an_py310.py hl[18:20] *}

/// note | 참고

이 경우에는 본문에서 가져올 `item`이 선택사항이라는 점을 유의하세요. 기본값이 `None`이기 때문입니다.

///

## 다중 본문 매개변수 { #multiple-body-parameters }

이전 예제에서, *경로 처리*는 아래처럼 `Item`의 속성을 가진 JSON 본문을 예상합니다:

首先，毫无疑问地，你可以随意地混合使用 `Path`、`Query` 和请求体参数声明，**FastAPI** 会知道该如何处理。

你还可以通过将默认值设置为 `None` 来将请求体参数声明为可选参数：

{* ../../docs_src/body_multiple_params/tutorial001_an_py310.py hl[18:20] *}

/// note | 注意

请注意，在这种情况下，将从请求体获取的 `item` 是可选的。因为它的默认值为 `None`。

///

## 多个请求体参数 { #multiple-body-parameters }

在上面的示例中，*路径操作*将期望一个具有 `Item` 的属性的 JSON 请求体，就像：

```JSON

    Our workaround is to tell GWT that util.concurrent and all other packages
    have prod supersource, even if they have none. GWT is happy to ignore us
    when we specify a nonexistent path.

    (I hope that this workaround does not cause its own problems in the future.)

/// note

FastAPI will know that the value of `q` is not required because of the default value `= None`.

The `str | None` is not used by FastAPI to determine that the value is not required, it will know it's not required because it has a default value of `= None`.

But the example here uses `PATCH` because it was created for these use cases.

///

/// note

Notice that the input model is still validated.

So, if you want to receive partial updates that can omit all the attributes, you need to have a model with all the attributes marked as optional (with default values or `None`).
