{ "button": [ { "name": "链接", "sub_button": [ { "type": "view", "name": "搜索", "url": "http://www.baidu.com/" }, { "type": "view", "name": "视频", "url": "http://v.qq.com/" }, { "type": "click", "name": "赞一下我们", "key": "BTN_GOOD" } ] }, { "name": "查询天气", "sub_button": [ { "type": "click", "name": "武汉", "key": "BTN_TQ_WUHAN" }, { "type": "click", "name": "上海", "key": "BTN_TQ_SHANGHAI" }, { "type": "click", "name": "北京", "key": "BTN_TQ_BEIJING" } ] }, { "type": "click", "name": "帮助", "key": "BTN_HELP" } ] }
3、管理菜单
因为菜单的变更没有那么频繁，因此通过txt文件来设置菜单，并通过管理界面来管理菜单。
主要的管理功能：
1）从文件加载菜单
2）创建菜单。即将菜单通知微信服务端，并更新至微信客户端
3）查询菜单。获取当前系统的菜单。
4）删除菜单。从微信服务器删除菜单，也可以删除后再创建。
实现代码如下：
public class MenuManager { /// <summary> /// 菜单文件路径 /// </summary> private static readonly string Menu_Data_Path = System.AppDomain.CurrentDomain.BaseDirectory + "/Data/menu.txt"; /// <summary> /// 获取菜单 /// </summary> public static string GetMenu() { string url = string.Format("https://api.weixin.qq.com/cgi-bin/menu/get?access_token={0}", Context.AccessToken); return HttpUtility.GetData(url); } /// <summary> /// 创建菜单 /// </summary> public static void CreateMenu(string menu) { string url = string.Format("https://api.weixin.qq.com/cgi-bin/menu/create?access_token={0}", Context.AccessToken); //string menu = FileUtility.Read(Menu_Data_Path); HttpUtility.SendHttpRequest(url, menu); } /// <summary> /// 删除菜单 /// </summary> public static void DeleteMenu() { string url = string.Format("https://api.weixin.qq.com/cgi-bin/menu/delete?access_token={0}", Context.AccessToken); HttpUtility.GetData(url); } /// <summary> /// 加载菜单 /// </summary> /// <returns></returns> public static string LoadMenu() { return FileUtility.Read(Menu_Data_Path); } }
4、基本方法
上面的代码，其实我们对一些公共功能做了封装。如进行get请求、POST提交等操作，读取文件等。
这里我们提供进行get、Post提交的方法案例代码，如果使用，建议优化。
using System; using System.IO; using System.Net; using System.Text; using System.Web; namespace Yank.WeiXin.Robot.Utility { /// <summary> /// Http帮助类 /// </summary> class HttpUtility { /// <summary> /// 发送请求 /// </summary> /// <param>Url地址</param> /// <param>数据</param> public static string SendHttpRequest(string url, string data) { return SendPostHttpRequest(url,"application/x-www-form-urlencoded",data); } /// <summary> /// /// </summary> /// <param></param> /// <returns></returns> public static string GetData(string url) { return SendGetHttpRequest(url,"application/x-www-form-urlencoded"); } /// <summary> /// 发送请求 /// </summary> /// <param>Url地址</param> /// <param>方法（post或get）</param> /// <param>数据类型</param> /// <param>数据</param> public static string SendPostHttpRequest(string url,string contentType,string requestData) { WebRequest request = (WebRequest)HttpWebRequest.Create(url); request.Method = "POST"; byte[] postBytes = null; request.ContentType = contentType; postBytes = Encoding.UTF8.GetBytes(requestData); request.ContentLength = postBytes.Length; using (Stream outstream = request.GetRequestStream()) { outstream.Write(postBytes, 0, postBytes.Length); } string result = string.Empty; using (WebResponse response = request.GetResponse()) { if (response != null) { using (Stream stream = response.GetResponseStream()) { using (StreamReader reader = new StreamReader(stream, Encoding.UTF8)) { result = reader.ReadToEnd(); } } } } return result; } /// <summary> /// 发送请求 /// </summary> /// <param>Url地址</param> /// <param>方法（post或get）</param> /// <param>数据类型</param> /// <param>数据</param> public static string SendGetHttpRequest(string url, string contentType) { WebRequest request = (WebRequest)HttpWebRequest.Create(url); request.Method = "GET"; request.ContentType = contentType; string result = string.Empty; using (WebResponse response = request.GetResponse()) { if (response != null) { using (Stream stream = response.GetResponseStream()) { using (StreamReader reader = new StreamReader(stream, Encoding.UTF8)) { result = reader.ReadToEnd(); } } } } return result; } } }
