**FastAPI** はそれぞれを認識し、適切な場所からデータを取得します。

{* ../../docs_src/body/tutorial004.py hl[18] *}

関数パラメータは以下の様に認識されます:

* パラメータが**パス**で宣言されている場合は、優先的にパスパラメータとして扱われます。
* パラメータが**単数型** (`int`、`float`、`str`、`bool` など)の場合は**クエリ**パラメータとして解釈されます。
* パラメータが **Pydantic モデル**型で宣言された場合、リクエスト**ボディ**として解釈されます。

/// note | 備考

FastAPIは、`= None`があるおかげで、`q`がオプショナルだとわかります。

### 검증

* 다음을 포함한, 대부분의 (혹은 모든?) 파이썬 **데이터 타입** 검증할 수 있습니다:
    * JSON 객체 (`dict`).
    * 아이템 타입을 정의하는 JSON 배열 (`list`).
    * 최소 길이와 최대 길이를 정의하는 문자열 (`str`) 필드.
    * 최솟값과 최댓값을 가지는 숫자 (`int`, `float`), 그 외.

* 다음과 같이 더욱 이색적인 타입에 대해 검증할 수 있습니다:
    * URL.
    * 이메일.
    * UUID.
    * ...다른 것들.

모든 검증은 견고하면서 잘 확립된 **Pydantic**에 의해 처리됩니다.
