    // main 函数生成快捷键 psvm
    public static void main(String[] args) {
        // 创建按钮
        // 创建一级菜单
        Button button=new Button();
        List buttons = new ArrayList<>();
        // 一级菜单中第一个按钮
        ClickButton clickButton=new ClickButton("查看爆料");
        clickButton.setKey("1");
        // 1-2
        ViewButton viewButton=new ViewButton("baidu","http://www.baidu.com");
        // 1-3  二级菜单
        SubButton subButton=new SubButton("更多");
        List subButtons=new ArrayList<>();
        // 2-1
        subButtons.add(new ViewButton("千锋","http://www.qfedu.cn"));
        // 2-2
        subButtons.add(new PhotoOrAlbumButton("上传图片","2"));
        subButton.setSub_button(subButtons);
        // 把一级菜单的三个按钮添加进集和
        buttons.add(clickButton);
        buttons.add(viewButton);
        buttons.add(subButton);

        // 把集合添加到一级菜单中
        button.setButton(buttons);

        // 转换为json字符串   可以考虑使用fastjson
        JSONObject jsonObject = JSONObject.fromObject(button);
        String json = jsonObject.toString();
        String url = String.format("https://api.weixin.qq.com/cgi-bin/menu/create?access_token=%s", TokenUtil.getAccessToken());
        //发送请求
        String result = HttpUtil.doPost(url, json);
        System.out.println("result以获取：");
        System.out.println(result);
    }
}

这里提示报错：

result以获取：

{"errcode":40020,"errmsg":"invalid button url size rid: 66250498-6dc28843-47afdcb9"}
