菜单处理

创建菜单

    err := wx.Menu.Create(
		menu.RootMenu{
			Menus: []menu.Item{
				&menu.ClickMenu{
					Name: "点击测试",
					Key:  "click_test",
				},
				&menu.SubMenu{
					Name: "二级菜单",
					Menus: []menu.Item{
						&menu.ViewMenu{
							Name: "博客",
							Url:  "https://dreamer2q.wang",
						},
						&menu.ClickMenu{
							Name: "关于我",
							Key:  "click_about",
						},
						&menu.ClickMenu{
							Name: "点我没反应",
							Key:  "noempty",
						},
					},
				},
			},
		})
	if err != nil {
		log.Panic(err)
    }

处理菜单事件

方法一，订阅事件

	wx.On("event.CLICK.click_test", func(msg wc.MessageReceive) wc.MessageReply {
		return wc.Text{Content: "点击菜单测试"}
	})
	wx.On("event.CLICK.click_about", func(msg wc.MessageReceive) wc.MessageReply {
		return wc.Text{Content: "关于我： 我是傻逼开发者"}
	})
	wx.On("event.CLICK.noempty", func(msg wc.MessageReceive) wc.MessageReply {
		return nil //no reply
	})
	wx.On("event.VIEW.https://dreamer2q.wang", func(msg wc.MessageReceive) wc.MessageReply {
		log.Printf("view event") //记录事件
		return nil
	})

方法二，在总事件中处理

    wx.SetEventHandler(func(m wc.MessageReceive) wc.MessageReply {
		log.Printf("EventHandler: user %s: %s\n", m.FromUserName, m.Event)
		switch m.Event {
		case wc.EvClick:
			switch m.EventKey {
			case "click_test":
				return wc.Text{Content: "点击菜单测试"}
			case "click_about":
				return wc.Text{Content: "关于我，我是xxxx"}
			case "noempty":
				return nil
			}
		case wc.EvView:
			log.Printf("view event: %s", m.EventKey)
		}
		return nil
	})

订阅事件优先级高，以高优先级处理结果为准。
