subscribe_msg_change_event事件推送到服务器发现List并不是数组类型，而是如下的json类型：

{"ToUserName":"gh_bdfaa9af5a04","FromUserName":"oGeAO45Tq8ZWNtI10PsK9kpBvFDU","CreateTime":1696991702,"MsgType":"event","Event":"subscribe_msg_change_event","List":{"SubscribeStatusString":"reject","TemplateId":"UA2FxrBpGqwOwb1I9eymbw-ZGyKtSQFhgAC44Z5AraY"},"Encrypt":"Sq6jOGru+P1CfuBMxHdcknOL4HGwSWn2ZQ/mlyr+2wWfxH49+CQ9D83FC7+vCpPrmN9cakbyOsqBHrgZq7KXbKOeJAc7nLS91fj4HrScBT9CdfaK4dkDIUexWeP4/xsyLfvIUQE5xuUMIGQr2LBfVaLvA2XBt52kgHiwvA97SSYlnm8Sqhas92tjdySs36+ikvd+W09pZxtbpMecQm1RvcTWR1yn8lSW/jTAb0NviBSHBjdZuSzyupItCWW8bG+vhCAXtI9oV2fA7DtYj+iTnVvb7P67EIMnbgh15iaKBZEB2kFhxUlTOjeAdGihSnHHJgWFzCNB6HZV1fSbU3Czc/etnYBCA7qz7UF4KO6QxvAwXnmTzrnDACFzKXcLvK/EKxeGR6lnfHTxcq/dnYuUeL9chlzbi5L2rGI9evTJz6g="}

但是有时候超过1个以上模板修改订阅状态又是数组，这也太神奇了吧。
