	// If you need to configure the validator, you can use the following
	//go_tagexpr.MustRegTypeUnmarshal
	h := server.New(server.WithCustomBinder(binder))
	h.GET("/ping", func(c context.Context, ctx *app.RequestContext) {
		var req Test
		err := ctx.BindAndValidate(&req)
		if err != nil {
			fmt.Println(err)
			ctx.String(400, err.Error())
			return
		}
		fmt.Println(req)
		ctx.JSON(200, req)
	})

	go h.Spin()
	time.Sleep(100 * time.Millisecond)
	hc := http.Client{Timeout: 1000 * time.Second}
	hc.Get("http://127.0.0.1:8888/ping?q=99")
