# Parámetros de Header { #header-parameters }

Puedes definir los parámetros de Header de la misma manera que defines los parámetros de `Query`, `Path` y `Cookie`.

## Importar `Header` { #import-header }

Primero importa `Header`:

{* ../../docs_src/header_params/tutorial001_an_py310.py hl[3] *}

## Declarar parámetros de `Header` { #declare-header-parameters }

# Header-параметри

Ви можете визначати параметри заголовків, так само як визначаєте `Query`, `Path` і `Cookie` параметри.

## Імпорт `Header`

Спочатку імпортуйте `Header`:

{* ../../docs_src/header_params/tutorial001_an_py310.py hl[3] *}

## Оголошення параметрів `Header`

Потім оголосіть параметри заголовків, використовуючи ту ж структуру, що й для `Path`, `Query` та `Cookie`.

ヘッダーのパラメータは、`Query`や`Path`、`Cookie`のパラメータを定義するのと同じように定義できます。

## `Header`をインポート

まず、`Header`をインポートします:

{* ../../docs_src/header_params/tutorial001.py hl[3] *}

## `Header`のパラメータの宣言

次に、`Path`や`Query`、`Cookie`と同じ構造を用いてヘッダーのパラメータを宣言します。

最初の値がデフォルト値で、追加の検証パラメータや注釈パラメータをすべて渡すことができます。

{* ../../docs_src/header_params/tutorial001.py hl[9] *}

/// note | 技術詳細

`Header`は`Path`や`Query`、`Cookie`の「姉妹」クラスです。また、同じ共通の`Param`クラスを継承しています。
