利用Go语言开发上门做菜系统的配送员位置实时监控功能有哪些创新之处？

package main

import (
    "log"
    "net/http"

    "GitHub.com/gorilla/websocket"
)

var upgrader = websocket.Upgrader{} // 创建一个WebSocket升级器

func wsHandler(w http.ResponseWriter, r *http.Request) {
    conn, err := upgrader.Upgrade(w, r, nil) // 升级HTTP连接为WebSocket连接
    if err != nil {
        log.Println(err)

        // 发送位置更新给客户端
