配置用户登录token的过期时间

自定义配置token过期时间：

JWT_AUTH = {
    'JWT_RESPONSE_PAYLOAD_HANDLER': 'app02.utils.my_jwt_response_payload_handler',
    # 自定配置token过期时间
    # days: float = ...,
    # seconds: float = ...,
    # microseconds: float = ...,
    # milliseconds: float = ...,
    # minutes: float = ...,
    # hours: float = ...,
    # weeks: float = ...,
    'JWT_RESPONSE_DELTA': datetime.timedelta(days=7)  # 过期时间，手动配置
}
