	// Note: The size of the security token that STS APIs return is not fixed. We

# 헤더 매개변수 모델

관련 있는 **헤더 매개변수** 그룹이 있는 경우, **Pydantic 모델**을 생성하여 선언할 수 있습니다.

이를 통해 **여러 위치**에서 **모델을 재사용** 할 수 있고 모든 매개변수에 대한 유효성 검사 및 메타데이터를 한 번에 선언할 수도 있습니다. 😎

/// note | 참고

이 기능은 FastAPI 버전 `0.115.0` 이후부터 지원됩니다. 🤓

///

## Pydantic 모델을 사용한 헤더 매개변수

**Pydantic 모델**에 필요한 **헤더 매개변수**를 선언한 다음, 해당 매개변수를 `Header`로 선언합니다:

{* ../../docs_src/header_param_models/tutorial001_an_py310.py hl[9:14,18] *}

Ele não será serializado com um modelo, etc.

Garanta que ele tenha toda informação que você deseja, e que os valores sejam um JSON válido (caso você esteja usando `JSONResponse`).

Você também pode utilizar `from starlette.responses import JSONResponse`.
