微信小程序后台添加订阅消息，目前大多数服务类目下仅支持一次性订阅，持续更新中。若没有符合的消息模板，申请自定义模板即可，审核周期是挺长的。

填写模板时，一定要注意参数类型。

小程序发送订阅消息必须要获取用户接收消息的授权

小程序需调用

wx.requestSubscribeMessage({
        tmplIds: ['RYdO0OyVwOmFJ5M9whapadK55agtmvWuumc_utFr7D4', 'bgEvkAITRuYbPET0IOPn8QPurVkXP7V6vjfPl7XDzrM'],
        success(res) {
          console.log(res);
          if (res.RYdO0OyVwOmFJ5M9whapadK55agtmvWuumc_utFr7D4 == "accept") {
            console.log('已授权接收订阅消息');
          }
        }
      })
