4.1)菜单栏相关API

包括如下接口：

• createMenu - 创建菜单栏
• deleteMenu - 删除菜单栏
• getMenu - 获取菜单栏
• getMenuCurInfo - 获取当前菜单栏配置信息

1. createMenu 创建菜单栏

        WxMenu menu = new WxMenu();
        List<WxMenuButton> btnList = new ArrayList<>();

        //设置CLICK类型的按钮1
        WxMenuButton btn1 = new WxMenuButton();
        btn1.setType(WxConsts.BUTTON_CLICK);
        btn1.setKey("btn1_key");
        btn1.setName("CLICK按钮1");

        //设置VIEW类型的按钮2
        WxMenuButton btn2 = new WxMenuButton();
        btn2.setType(WxConsts.BUTTON_VIEW);
        btn2.setUrl("http://www.baidu.com");
        btn2.setName("VIEW按钮2");

        //设置含有子按钮的按钮3
        List<WxMenuButton> subList = new ArrayList<>();
        //子按钮
        WxMenuButton btn3_1 = new WxMenuButton();
        btnbtn3_1 .setType(WxConsts.BUTTON_VIEW);
        btnbtn3_1 .setUrl("http://www.baidu.com");
        btnbtn3_1 .setName("子按钮3_1");
        WxMenuButton btn3_2 = new WxMenuButton();
        btn3_2.setType(WxConsts.BUTTON_VIEW);
        btn3_2.setUrl("http://www.baidu.com");
        btn3_2.setName("子按钮3_2");
        subList.add(btn3_1);
        subList.add(btn3_2);
        //把子按钮列表设置进按钮3
        WxMenuButton btn3 = new WxMenuButton();
        btn3.setName("子按钮3");
        btn3.setSub_button(subList);

        //将三个按钮设置进btnList
        btnList.add(btn1);
        btnList.add(btn2);
        btnList.add(btn3);
        //设置进菜单类
        menu.setButton(btnList);
        //调用API即可
        try {
            //参数1--menu  ，参数2--是否是个性化定制。如果是个性化菜单栏，需要设置MenuRule
            iService.createMenu(menu, false);
        } catch (WxErrorException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        //个性化菜单栏
        WxMenuRule rule = new WxMenuRule();
        rule.setProvince("广东");
        menu.setMatchrule(rule);

        try {
            //参数1--menu  ，参数2--是否是个性化定制。如果是个性化菜单栏，需要设置MenuRule
            iService.createMenu(menu, true);
        } catch (WxErrorException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

2. deleteMenu 删除菜单栏

        try {
            iService.deleteMenu();
        } catch (WxErrorException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        //如果是删除个性化菜单栏，需要传入MenuID
        try {
            iService.deleteMenu("MenuID");
        } catch (WxErrorException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

3. getMenu 获取菜单栏

        try {
            WxMenuResult result = iService.getMenu();
            System.out.println(result.toString());
        } catch (WxErrorException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

4. getMenuCurInfo 获取现有菜单栏配置

        try {
            WxCurMenuInfoResult result = iService.getMenuCurInfo();
            System.out.println(result.toString());
        } catch (WxErrorException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
