golang table和数组的应用

type Data struct {
   Ts int64 `json:"ts"`
   Status int  `json:"status"`
   Type    int    `json:"type"`
   Msg string `json:"msg"`
   UserId string `json:"userId"`
   ImageId string `json:"imageId"`
}
data := &Data{}
data.Ts = tstimp
data.Status = statu
data.Type = receive.Type
data.Msg = msg
data.UserId = receive.UserId
data.ImageId = ""

var ss = make([]*Data, 0)

payload := make(map[string]interface{})
payload = map[string]interface{}{
   "cmd":  YH_CMD6_DOORSTATUS,
   "data": append(ss,data),
}
