## README

为了开发方便，封装了一个小小的不像引擎的模板引擎
建议在main里只注册一个http.Handle("/")，在回调函数里对engine进行初始化，因为NewEngine是单例模式
例如：engine:=tplEngine.NewEngine(w,r,fs)
注意fs参数，可以调用tplEngine.fs.NewEmbedFS(embedFs)来嵌入静态资源目录
或调用tplEngine.fs.NewLocalFS(dir)来调用本地文件系统

编译时加参数：-ldflags="-X main.DEBUG=1" 开启调试模式，作用是对html文件的修改即时生效，否则编译后，html文件内嵌到可执行文件里

例子：
//go:embed html
var embedFS embed.FS
func main() {
	var mfs fs.FS
	if DEBUG == "1" {
		mfs = tfs.NewLocalFS("./html")
	} else {
		mfs = tfs.NewEmbedFS(embedFS)
	}

	ignoreAuthPath := []string{"/login"}

	http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
		engine := tplEngine.NewEngine(w, r, mfs)
		if !engine.StaticFile() {
			ignoreAuth := false
			for _, p := range ignoreAuthPath {
				if r.URL.Path == p {
					ignoreAuth = true
				}
			}
			if !ignoreAuth {
				auth(tplEngine.Handle(r.URL.Path), engine)(w, r)
			}else{
				tplEngine.Handle(r.URL.Path)(engine)
			}
		}
	})
	var listen net.Listener
	var err error
	if goframe.AppConf.GetString("global.listen")!="" {
		listen,err = net.Listen("tcp",goframe.AppConf.GetString("global.listen"))
	}else{
		listen,err = net.Listen("tcp","127.0.0.1:0")
	}
	if err != nil {
		log.Fatal(err.Error())
		return
	}
	fmt.Printf("listen on %s\n",listen.Addr())
	fmt.Printf("url http://%s\n",listen.Addr())
	log.Fatal(http.Serve(listen,nil))
