route evaluated but not used

func route(w http.ResponseWriter, r *http.Request) {
    //设置路由
    http.HandleFunc("/", home.Index) //首页

    err := http.ListenAndServe(":80", nil) //设置监听的端口
    if err != nil {
        fmt.Println(msg.Msg_maintenance)
    }
}

func Init() {
    route
}

报错 route evaluated but not used 怎么解决？
