まず、`Header`をインポートします:

```Python hl_lines="3"
{!../../../docs_src/header_params/tutorial001.py!}
```

## `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。

```Python hl_lines="9"
{!../../../docs_src/header_params/tutorial001.py!}
```

!!! 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。

まず、`Cookie`をインポートします:

```Python hl_lines="3"
{!../../../docs_src/cookie_params/tutorial001.py!}
```

## `Cookie`のパラメータを宣言

次に、`Path`や`Query`と同じ構造を使ってクッキ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:

```Python hl_lines="9"
{!../../../docs_src/cookie_params/tutorial001.py!}
```

Ansonsten würde der Pfad für `/users/{user_id}` auch `/users/me` auswerten, und annehmen, dass ein Parameter `user_id` mit dem Wert `"me"` übergeben wurde.

Sie können eine Pfadoperation auch nicht erneut definieren:

```Python hl_lines="6  11"

## `Header` 매개변수 선언

`Path`, `Query` 그리고 `Cookie`를 사용한 동일한 구조를 이용하여 헤더 매개변수를 선언합니다.

첫 번째 값은 기본값이며, 추가 검증이나 어노테이션 매개변수 모두 전달할 수 있습니다:

```Python hl_lines="9"
{!../../../docs_src/header_params/tutorial001.py!}
```

!!! note "기술 세부사항"
    `Header`는 `Path`, `Query` 및 `Cookie`의 "자매"클래스입니다. 이 역시 동일한 공통 `Param` 클래스를 상속합니다.

```Python hl_lines="3"
{!../../../docs_src/cookie_params/tutorial001.py!}
```

## Declare parâmetros de `Cookie`

Então declare os paramêtros de cookie usando a mesma estrutura que em `Path` e `Query`.

O primeiro valor é o valor padrão, você pode passar todas as validações adicionais ou parâmetros de anotação:

```Python hl_lines="9"
{!../../../docs_src/cookie_params/tutorial001.py!}
```
