用權杖有效期建立一個 `timedelta`。

建立真正的 JWT access token 並回傳它。

### 關於 JWT「主體」`sub` 的技術細節 { #technical-details-about-the-jwt-subject-sub }

JWT 規範說有個鍵 `sub`，代表權杖的主體（subject）。

使用它是可選的，但通常會把使用者的識別資訊放在這裡，所以我們在此採用。

JWT 除了用來識別使用者並允許他直接對你的 API 執行操作外，也可用於其他用途。

例如，你可以識別一台「車」或一篇「部落格文章」。

接著可以替該實體加上權限，如「drive」（對車而言）或「edit」（對文章而言）。

用令牌的过期时间创建一个 `timedelta`。

创建一个真正的 JWT 访问令牌并返回它。

### 关于 JWT “主题” `sub` 的技术细节 { #technical-details-about-the-jwt-subject-sub }

JWT 规范中有一个 `sub` 键，表示令牌的“主题”（subject）。

使用它是可选的，但通常会把用户的标识放在这里，所以本例中我们使用它。

JWT 除了用于识别用户并允许其直接在你的 API 上执行操作之外，还可能用于其他场景。

例如，你可以用它来标识一辆“车”或一篇“博客文章”。

然后你可以为该实体添加权限，比如“drive”（用于车）或“edit”（用于博客）。
