+	}
+	globalSession.RegisterEventHandler(&MyEventHandler{})
+	globalSession.Start()
+}
+
+type MyEventHandler struct {
+	event.BaseEventHandler
+}
+
+// DoKMarkDown 一个简单的Kook机器人实现,接受到新消息时会发送回对应频道/私聊
+func (h *MyEventHandler) DoKMarkDown(event *model.Event) {
+	content := event.Content
+	log.Infof("event:%v", event)
+	extra := event.GetUserExtra()
+	if extra.Author.Bot {
