  async redisTest2(req: Request, res: Response) {

    const user_id = 1;
    let data = {};

    // 尝试从 Redis 获取数据
    const user_info_str = await redis.get(`user:${ user_id }`);
    console.log(`user_info_str: ${ user_info_str }`)
    if (user_info_str) {
      const user_info = JSON.parse(user_info_str); // 手动解析为 JSON 对象
      console.log(`user_info: ${ user_info }`)
      data = { user_info }
    }
    ResponseUtil.success(res, data, '查询成功', 20000);
