正常用户向公众号发语音消息，后台服务器接收微信服务器正常回调：

{"appId":"wxe697462f724f2778","type":"voice","event":"","postObj":"{\"ToUserName\":\"gh_d44360---\",\"FromUserName\":\"oFDys6dUeflPxFRPiEI8K0xi_Jbg\",\"CreateTime\":\"1658478922\",\"MsgType\":\"voice\",\"MediaId\":\"egy91alBHTzG6KmMi6JEr5VgRvDoC19Mu66S95-BspFNQuUYEbOd7IKKvCw7x8a-\",\"Format\":\"amr\",\"MsgId\":\"23743709806122844\",\"Recognition\":{}}"}

open_id:oFDys6TEnZqIsvGrsNQzAn015iRo用户的异常回调：

{"appId":"wxe697462f724f2778","type":"event","event":"templatesendjobfinish","postObj":"{\"ToUserName\":\"gh_d44\",\"FromUserName\":\"oFDys6en6FWabzwTxrVvMWS3ELT8\",\"CreateTime\":\"1658479027\",\"MsgType\":\"event\",\"Event\":\"TEMPLATESENDJOBFINISH\",\"MsgID\":\"2497905266931007488\",\"Status\":\"success\"}"}

竟然变成其他用户的模板消息，都乱套了！！！服务器接收不到"MsgType\":\"voice\"的消息，所以现在是接收不到的，微信公众号后台可以看到异常用户的发送过来的语音消息。文本消息服务器能收到回调类型"MsgType\":\"text\"，就是语音消息异常!!!!!
