后台逻辑

定义消息模板类型

 /// <summary>
    /// 订阅模板消息  基本项
    /// </summary>
    public class MpTempleteMessageBaseItem
    {
        public string value { get; set; }

        
    }

/// <summary>
    /// 经营数据通知
    /// </summary>
    public class MpBusinessDataTempleteMessage

        /// <summary>
        /// 商品总额
        /// </summary>

        /// <summary>
        /// 储值总额

        /// 销售单数

        /// <summary>
        /// 统计时间
        /// </summary>
        public MpTempleteMessageBaseItem time5 { get; set; }
    }

订阅消息模型

 /// <summary>
    /// 订阅消息模型

获取 token

 public Result GetAccessToken()
        {
            var _result = new Result();
            try

                _result.success = true;
                _result.data = cacheModel;

            catch (Exception ex)
            {

                _result.message = ex.Message;
            }

            return _result;

        }

封装订阅消息模型

 private MpBusinessDataTempleteMessage GetMpBusinessDataTempleteMessage(SendMessageRequestDto input)
        {
            return new MpBusinessDataTempleteMessage()
            {

                },
                amount2 = new MpTempleteMessageBaseItem()
                {
                    value = input.key_word2
                },
                amount4 = new MpTempleteMessageBaseItem()

                }

            };
        }
