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。

比如说监听小程序事件，返回的参数MsgType、Event 有哪些枚举值，哪些是订阅消息？哪些是客服

多了一个 { "template_id": "p4nWjDG_G6VxaybCWr55d83y6XXcMFuK2kSKlhWfZFE", "title": "订阅模板消息", "primary_industry": "", "deputy_industry": "", "content": "{{content.DATA}}", "example": "" }

比如说查询某个小程序消息订阅用户数之类的。
