Neste exemplo utilizamos cabeçalhos personalizados inventados `X-Keys` e `X-Token`.

Mas em situações reais, como implementações de segurança, você pode obter mais vantagens em usar as [Ferramentas de segurança integradas (o próximo capítulo)](../security/index.md){.internal-link target=_blank}.

# 現在のユーザーの取得

一つ前の章では、（依存性注入システムに基づいた）セキュリティシステムは、 *path operation関数* に `str` として `token` を与えていました:

```Python hl_lines="10"
{!../../docs_src/security/tutorial001.py!}
```

しかし、それはまだそんなに有用ではありません。

現在のユーザーを取得するようにしてみましょう。

## ユーザーモデルの作成

まずは、Pydanticのユーザーモデルを作成しましょう。

ボディを宣言するのにPydanticを使用するのと同じやり方で、Pydanticを別のどんなところでも使うことができます:

```Python hl_lines="5  12-16"
{!../../docs_src/security/tutorial002.py!}
```

                                                key="labels.access_token_token"/></th>

                                    <tr>
                                        <th><la:message key="labels.permissions"/></th>
