把输出复制到变量 `SECRET_KEY`（不要使用示例中的那个）。

创建变量 `ALGORITHM`，设置用于签名 JWT 令牌的算法，这里设为 `"HS256"`。

创建一个变量用于设置令牌的过期时间。

定义一个用于令牌端点响应的 Pydantic 模型。

创建一个生成新访问令牌的工具函数。

그리고 출력 결과를 변수 `SECRET_KEY`에 복사합니다(예제의 값을 사용하지 마십시오).

JWT 토큰을 서명하는 데 사용될 알고리즘을 위한 변수 `ALGORITHM`을 생성하고 `"HS256"`으로 설정합니다.

토큰 만료를 위한 변수를 생성합니다.

응답을 위해 토큰 엔드포인트에서 사용될 Pydantic 모델을 정의합니다.

새 액세스 토큰을 생성하기 위한 유틸리티 함수를 생성합니다.

   * One of the key challenges of this class is to prevent lost signals, while trying hard to
