通过https//api.weixin.qq.com/cgi-bin/media/upload?access_token=access_token&type=image 来上传图片，获得media_id
然后通过 https//api.weixin.qq.com/cgi-bin/message/custom/send?access_token=access_token 给用户发送小程序
{
"touser""'touser",
"msgtype": "miniprogrampage",
"miniprogrampage": {
  "title": "你师傅被抓走了",
   "pagepath": "index",
   "thumb_media_id":"media_id",
  }
}

一直报错invalid media_id hint: [jVjj2a00493941]  access_token 我可以保证是同一个小游戏的，请大佬帮忙解决
