## `Cookie`をインポート

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!}
```
