调用的接口是https://api.weixin.qq.com/cgi-bin/message/mass/sendall?access_token=

传的参数为{"filter":{"is_to_all":"false","tag_id":1},"mpnews":{"media_id":"flkrsp5xoCn6_OQ7JoEDxSOTa3iglJDlB-7beBYP69HmnszeekRGGy8Vhs_tIRIe"},"send_ignore_reprint":0,"msgtype":"mpnews"}

传的格式是json啊，为啥还是通不过json校验

返回报错为{"errcode":40008,"errmsg":"invalid message type rid: 6593c6bf-23b03fa6-12e8dbc9"}
