## `/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。

JWTアクセストークンを作成し、それを返します。

### JWTの"subject" `sub` についての技術的な詳細

JWTの仕様では、トークンのsubjectを表すキー`sub`があるとされています。

使用するかどうかは任意ですが、`sub`はユーザーの識別情報を入れるように規定されているので、ここで使用します。

JWTは、ユーザーを識別して、そのユーザーがAPI上で直接操作を実行できるようにする以外にも、他の用途で使用されることがあります。

例えば、「車」や「ブログ記事」を識別することができます。

   *
   * Writes are subject to the write window of the stream and the connection. Until there is a
   * window sufficient to send [byteCount], the caller will block. For example, a user of
   * `HttpURLConnection` who flushes more bytes to the output stream than the connection's write
   * window will block.
   *
   * Zero [byteCount] writes are not subject to flow control and will not block. The only use case

### Detalhes técnicos sobre o "sujeito" `sub` do JWT { #technical-details-about-the-jwt-subject-sub }

A especificação JWT diz que existe uma chave `sub`, com o sujeito do token.

É opcional usá-la, mas é onde você colocaria a identificação do usuário, então nós estamos usando aqui.

      valueHolder.name = checkNotNull(name);
      return this;
    }

    // Holder object for values that might be null and/or empty.
    static class ValueHolder {
      @Nullable String name;
      @Nullable Object value;
      @Nullable ValueHolder next;
    }

### Technische Details zum JWT-„Subjekt“ `sub` { #technical-details-about-the-jwt-subject-sub }

Die JWT-Spezifikation besagt, dass es einen Schlüssel `sub` mit dem Subjekt des Tokens gibt.

Die Verwendung ist optional, aber dort würden Sie die Identifikation des Benutzers speichern, daher verwenden wir das hier.

La especificación de JWT dice que hay una clave `sub`, con el sujeto del token.
