	MsgType_Heart   MsgType = 4
)

type POINT

type POINT struct {
	//Id uint32
	X float64 `json:"x"`
	Y float64 `json:"y"`
}

以下为约定结构

type ReqGetIDMsg

type ReqGetIDMsg struct {
	DeviceId string `json:"deviceId"`
	Ip       string `json:"ip"`
}

ReqGetIDMsg 客户请求 json 设备信息和ip地址 存在redis中

type RetGetIDMsg

type RetGetIDMsg struct {
	Id uint32 `json:"id"`
