Antes do FastAPI 0.108.0, Starlette 0.29.0, `name` era o primeiro parâmetro.

## `Path`、`Query`とボディパラメータを混ぜる

まず、もちろん、`Path`と`Query`とリクエストボディのパラメータの宣言は自由に混ぜることができ、 **FastAPI** は何をするべきかを知っています。

また、デフォルトの`None`を設定することで、ボディパラメータをオプションとして宣言することもできます:

{* ../../docs_src/body_multiple_params/tutorial001.py hl[19,20,21] *}

/// note | 備考

この場合、ボディから取得する`item`はオプションであることに注意してください。デフォルト値は`None`です。

///

## 複数のボディパラメータ

上述の例では、*path operations*は`item`の属性を持つ以下のようなJSONボディを期待していました:

```JSON
{

## Paramètres optionnels

De la même façon, vous pouvez définir des paramètres de requête comme optionnels, en leur donnant comme valeur par défaut `None` :

{* ../../docs_src/query_params/tutorial002.py hl[9] *}

Ici, le paramètre `q` sera optionnel, et aura `None` comme valeur par défaut.

/// note | Заметка

FastAPI понимает, что значение `q` не является обязательным из-за значения по умолчанию `= None`.

Аннотации типов `str | None` (Python 3.10+) или `Union[str, None]` (Python 3.9+) не используются FastAPI для определения обязательности; он узнает, что параметр не обязателен, потому что у него есть значение по умолчанию `= None`.

    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.)
