レスポンスのトークンエンドポイントで使用するPydanticモデルを定義します。

新しいアクセストークンを生成するユーティリティ関数を作成します。

## 依存関係の更新

`get_current_user`を更新して、先ほどと同じトークンを受け取るようにしますが、今回はJWTトークンを使用します。

受け取ったトークンを復号して検証し、現在のユーザーを返します。

トークンが無効な場合は、すぐにHTTPエラーを返します。

## `/token` パスオペレーションの更新

トークンの有効期限を表す`timedelta`を作成します。

   reported vulnerability and how it might be exploited. Alternatively,
   a well-established vulnerability identifier, e.g. CVE number, can be
   used instead.

Based on the description mentioned above, a MinIO engineer or security team
member investigates:

- Whether the reported vulnerability exists.
- The conditions that are required such that the vulnerability can be exploited.
- The steps required to fix the vulnerability.

# Seguridad { #security }

Hay muchas formas de manejar la seguridad, autenticación y autorización.

Y normalmente es un tema complejo y "difícil".

En muchos frameworks y sistemas, solo manejar la seguridad y autenticación requiere una gran cantidad de esfuerzo y código (en muchos casos puede ser el 50% o más de todo el código escrito).

We are using an invented header to simplify this example.

But in real cases you will get better results using the integrated [Security utilities](security/index.md){.internal-link target=_blank}.
