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。

```Python hl_lines="6  12-14  28-30  78-86"
{!../../docs_src/security/tutorial004.py!}
```

## 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。

```Python hl_lines="89-106"
{!../../docs_src/security/tutorial004.py!}
```

## `/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。

The benefit of raising an exception over `return`ing a value will be more evident in the section about Dependencies and Security.

In this example, when the client requests an item by an ID that doesn't exist, raise an exception with a status code of `404`:

```Python hl_lines="11"
