*       to construct the sample instances. In case of tie, the candidate constructors or
   *       factories are tried one after another until one can be used to construct sample
   *       instances.
   *   <li>For the constructor or static factory method used to construct instances, it's checked

      When doing so, still annotate nullable parameters and the return type as `@Nullable`.
  * Do not use `@Contract` for public APIs.
  * For polynull public APIs, the solution has to be decided on a case-by-case basis.

Do not remove `null` checks on public API boundaries, even if the annotations (or rather lack of them) suggest this.
Not all client code is compiled with NullAway.

## 複数のパスパラメータとクエリパラメータ { #multiple-path-and-query-parameters }

複数のパスパラメータとクエリパラメータを同時に宣言できます。**FastAPI**はどれがどれかを把握しています。

そして特定の順序で宣言しなくてもよいです。

名前で判別されます:

## 必須のクエリパラメータ { #required-query-parameters }

パスパラメータ以外のパラメータ (今のところ、クエリパラメータのみ見てきました) のデフォルト値を宣言した場合、そのパラメータは必須ではなくなります。

## 요청 본문 + 경로 매개변수 { #request-body-path-parameters }

경로 매개변수와 요청 본문을 동시에 선언할 수 있습니다.

**FastAPI**는 경로 매개변수와 일치하는 함수 매개변수가 **경로에서 가져와야 한다**는 것을 인지하며, Pydantic 모델로 선언된 그 함수 매개변수는 **요청 본문에서 가져와야 한다**는 것을 인지할 것입니다.

## 요청 본문 + 경로 + 쿼리 매개변수 { #request-body-path-query-parameters }
