C#-MVC开发微信应用(8)--菜单管理的实现

之前讲解了微信后台管理页面的操作来管理菜单，下面我们在简单的来看一下，代码是如何实现的。

我们要实现获取微信的菜单、创建菜单、删除菜单等操作。

01.首先定义菜单操作的接口：

 /// <summary>
    /// 菜单的相关操作
    /// </summary>
    public interface IMenuApi
    {
        /// <summary>
        /// 获取菜单数据
        /// </summary>
        /// <param name="accessToken">调用接口凭证</param>
        /// <returns></returns>
        MenuJson GetMenu(string accessToken);

        /// <summary>
        /// 创建菜单
        /// </summary>
        /// <param name="accessToken">调用接口凭证</param>
        /// <param name="menuJson">菜单对象</param>
        /// <returns></returns>
        CommonResult CreateMenu(string accessToken, MenuJson menuJson);

        /// <summary>
        /// 删除菜单
        /// </summary>
        /// <param name="accessToken">调用接口凭证</param>
        /// <returns></returns>
        CommonResult DeleteMenu(string accessToken);
    }

02.实现接口如下：

 /// <summary>
    /// 菜单的相关操作
    /// </summary>
    public class MenuApi : IMenuApi
    {
        #region 获取菜单数据 GetMenu(string accessToken)
        /// <summary>
        /// 获取菜单数据
        /// </summary>
        /// <param name="accessToken">调用接口凭证</param>
        /// <returns></returns>
        public MenuJson GetMenu(string accessToken)
        {
            string jsonStr = BasicAPI.RequestGetUrl(string.Format("https://api.weixin.qq.com/cgi-bin/menu/get?access_token={0}", accessToken));

            MenuListJson listMenu = JsonConvert.DeserializeObject<MenuListJson>(jsonStr);
            if (listMenu != null)
            {
                return listMenu.menu;
            }

            return null;
        }
        #endregion

        #region 创建菜单 CreateMenu(string accessToken, MenuJson menuJson)
        /// <summary>
        /// 创建菜单
        /// </summary>
        /// <param name="accessToken">调用接口凭证</param>
        /// <param name="menuJson">菜单对象</param>
        /// <returns></returns>
        public CommonResult CreateMenu(string accessToken, MenuJson menuJson)
        {
            var url = string.Format("https://api.weixin.qq.com/cgi-bin/menu/create?access_token={0}", accessToken);
            string postData = menuJson.ToJson();
            return BasicAPI.RequestUrlPostDataResult(url, postData);
        }
        #endregion

        #region 删除菜单 DeleteMenu(string accessToken)
        /// <summary>
        /// 删除菜单
        /// </summary>
        /// <param name="accessToken">调用接口凭证</param>
        /// <returns></returns>
        public CommonResult DeleteMenu(string accessToken)
        {
            string jsonStr = BasicAPI.RequestGetUrl(string.Format("https://api.weixin.qq.com/cgi-bin/menu/delete?access_token={0}", accessToken));
            return new CommonResult(jsonStr);
        }
        #endregion
    }

03.还需要定义出菜单对应的实体类

 /// <summary>
    /// 菜单基本信息
    /// </summary>
    public class MenuInfo
    {
        /// <summary>
        /// 参数化构造函数,用于构造子菜单
        /// </summary>
        public MenuInfo()
        {
        }
/// <summary>
        /// 参数化构造函数,用于构造子菜单
        /// </summary>
        /// <param name="name">按钮名称</param>
        /// <param name="sub_button">子菜单集合</param>
        public MenuInfo(string name, IEnumerable<MenuInfo> sub_button)
        {
            this.name = name;
            this.sub_button = new List<MenuInfo>();
            this.sub_button.AddRange(sub_button);
        }

        /// <summary>
        /// 参数化构造函数,用于构造子菜单
        /// </summary>
        /// <param name="name">按钮名称</param>
        public MenuInfo(string name)
        {
            this.name = name;
            this.sub_button = new List<MenuInfo>();
        }

        /// <summary>
        /// 按钮描述，既按钮名字，不超过16个字节，子菜单不超过40个字节
        /// </summary>
        [JsonProperty(NullValueHandling = NullValueHandling.Ignore)]
        public string name { get; set; }

        /// <summary>
        /// 按钮类型（click或view）
        /// </summary>
        [JsonProperty(NullValueHandling = NullValueHandling.Ignore)]
        public string type { get; set; }

        /// <summary>
        /// 按钮KEY值，用于消息接口(event类型)推送，不超过128字节
        /// </summary>
        [JsonProperty(NullValueHandling = NullValueHandling.Ignore)]
        public string key { get; set; }

        /// <summary>
        /// 网页链接，用户点击按钮可打开链接，不超过256字节
        /// </summary>
        [JsonProperty(NullValueHandling = NullValueHandling.Ignore)]
        public string url { get; set; }

        /// <summary>
        /// 子按钮数组，按钮个数应为2~5个
        /// </summary>
        [JsonProperty(NullValueHandling = NullValueHandling.Ignore)]
        public List<MenuInfo> sub_button { get; set; }

    }

04.还会用到，区分是事件类型的枚举值

public enum ButtonType
    {
        click, //
        view   //
    }

05. 那么如果调用呢

//01.创建菜单
            List<MenuInfo> lis = new List<MenuInfo>();
            lis.Add(new MenuInfo("代码生成工具", ButtonType.click, "CodeGenerator"));
            lis.Add(new MenuInfo("通用审核流", ButtonType.click, "WorkFlow"));
            lis.Add(new MenuInfo("单据编码生成器", ButtonType.click, "CodeRule"));

            MenuInfo productInfo2 = new MenuInfo("软件产品", lis);

            MenuInfo productInfo = new MenuInfo("软件产品", new MenuInfo[] {
                new MenuInfo("代码生成工具", ButtonType.click, "CodeGenerator"),
                new MenuInfo("通用审核流", ButtonType.click, "WorkFlow"),
                new MenuInfo("单据编码生成器", ButtonType.click, "CodeRule")
            });

            MenuInfo frameworkInfo = new MenuInfo("框架产品", new MenuInfo[] {
                new MenuInfo("Win开发框架", ButtonType.click, "WinForm"),
                new MenuInfo("Web开发框架", ButtonType.click, "MVC"),
                new MenuInfo("微信开发框架", ButtonType.click, "WeiXin"),
                new MenuInfo("代码生成工具", ButtonType.click, "CodeGenerator")
            });

            MenuInfo relatedInfo = new MenuInfo("相关链接", new MenuInfo[] {
                new MenuInfo("公司介绍", ButtonType.click, "Event_Company"),
                new MenuInfo("官方网站", ButtonType.view, "http://www.cnblogs.com/spring_wang"),
                //new MenuInfo("提点建议", ButtonType.click, "Event_Suggestion"),
                new MenuInfo("联系客服", ButtonType.click, "Event_Contact"),
                new MenuInfo("发邮件", ButtonType.view, "http://mail.qq.com/cgi-bin/qm_share?t=qm_mailme&email=cElAQ0ZDSUBGRzABAV4THx0")
            });

            MenuJson menuJson = new MenuJson();
            menuJson.button.AddRange(new MenuInfo[] { productInfo, frameworkInfo, relatedInfo });

            MenuApi mapi = new MenuApi();

            //测试获取 acessToken
            //string accessToken = string.Empty;
            //WeiXinUserToNoEntity weixinUser = BasicAPI.GetWeiXinUser(this.UserInfo);
            //dynamic accToken = BasicAPI.GetAccessToken(weixinUser.AppID, weixinUser.Appsecret);
            //if (accToken.access_token != null) {
            //    accessToken = accToken.access_token as string;
            //}

            CommonResult result = mapi.CreateMenu(BasicAPI.GetWeiXinAccessToken(this.UserInfo), menuJson);
            Console.WriteLine("创建菜单：" + (result.Success ? "成功" : "失败:" + result.ErrorMessage));
            result = mapi.DeleteMenu(BasicAPI.GetWeiXinAccessToken(this.UserInfo));
            Console.WriteLine("删除菜单：" + (result.Success ? "成功" : "失败:" + result.ErrorMessage));

06.运行效果如下
