使用模板的模板ID为"3IUG5I6cXz4SLRNLnr4cWsiRcZY_-Y62iBKnSrzyIeo"(编号:1974),参数包括账单时间{{date1.DATA}}、账单金额{{amount2.DATA}}、抄表度数{{number3.DATA}}、用气量{{number4.DATA}}、用气地址{{thing6.DATA}}

实际提交数据:{"touser":"*******","data":{"amount2":{"value":"201.59"},"thing6":{"value":"测试信息"},"number3":{"value":"91.71"},"number4":{"value":"21.71"},"date1":{"value":"2025-01-20 11:49:01"}},"template_id":"3IUG5I6cXz4SLRNLnr4cWsiRcZY_-Y62iBKnSrzyIeo","miniprogram_state":"trail","lang":"zh_CN"}

但一直返回{"errcode":47001,"errmsg":"data format error rid: 678ded7d-24a918dc-659860eb"}，后来根据网上信息，增加http头部参数Content-Type=multipart/x-www-form-urlencoded或Content-Type=application/x-www-form-urlencoded或Content-Type=application/json都不行。

请问这个问题应该怎么解决，有示例么？
