requestXML是我單獨(dú)創(chuàng)建的一個(gè)類，該類聲明了消息中常用的屬性字段，如下：

 /// <summary>
 /// 接收消息的實(shí)體類
 /// </summary>
 public class RequestXML
 {
 private String toUserName = String.Empty;

 /// <summary>
 /// 本公眾號(hào)
 /// </summary>
 public String ToUserName{get;set;}

 /// <summary>
 /// 用戶微信號(hào)
 /// </summary>
 public String FromUserName{get;set;}

 /// <summary>
 /// 創(chuàng)建時(shí)間
 /// </summary>
 public String CreateTime{get;set;}

 /// <summary>
 /// 信息類型 
 /// </summary>
 public String MsgType{get;set;}

 /// <summary>
 /// 信息內(nèi)容
 /// </summary>
 public String Content{get;set;}

 

 /*以下為事件類型的消息特有的屬性*/
 /// <summary>
 /// 事件名稱
 /// </summary>
 public String EventName{get;set;}
 /// <summary>
 /// 事件值
 /// </summary>
 public string EventKey { get; set; }

 


 /*以下為圖文類型的消息特有的屬性*/
 /// <summary>
 /// 圖文消息的個(gè)數(shù)
 /// </summary>
 public int ArticleCount { get; set; }
 /// <summary>
 /// 圖文消息的標(biāo)題
 /// </summary>
 public string Title { get; set; }
 /// <summary>
 /// 圖文消息的簡(jiǎn)介
 /// </summary>
 public string Description { get; set; }
 /// <summary>
 /// 圖文消息圖片的鏈接地址
 /// </summary>
 public string PicUrl { get; set; }
 /// <summary>
 /// 圖文消息詳情鏈接地址
 /// </summary>
 public string Url { get; set; }
 /// <summary>
 /// 圖文消息集合
 /// </summary>
 public List<RequestXML> Articles { get; set;}

 

 /*以下為地理位置類型的消息特有的屬性*/
 /// <summary>
 /// 地理位置緯度
 /// </summary>
 public String Location_X { get; set; }

 /// <summary>
 /// 地理位置經(jīng)度
 /// </summary>
 public String Location_Y { get; set; }

 /// <summary>
 /// 地圖縮放比例
 /// </summary>
 public String Scale { get; set; }

 /// <summary>
 /// 地圖位置說明
 /// </summary>
 public String Label { get; set; }

 　　/// <summary>
 /// 語音消息特有字段
 /// </summary>
 public String Recognition { get; set; }


 
 }

繼續(xù)關(guān)注 ResponseMsg(requestXML);方法如下

 private void ResponseMsg(RequestXML requestXML)
 {
 string MsgType = requestXML.MsgType;

 try
 {
 //根據(jù)消息類型判斷發(fā)送何種類型消息
 switch (MsgType)
 {
  case "text":
  SendTextCase(requestXML);//發(fā)送文本消息
  break;
  case "event"://發(fā)送事件消息
  if (!string.IsNullOrWhiteSpace(requestXML.EventName) && requestXML.EventName.ToString().Trim().Equals("subscribe"))
  {
  SendWelComeMsg(requestXML);//關(guān)注時(shí)返回的圖文消息
  }
  else if (!string.IsNullOrWhiteSpace(requestXML.EventName) && requestXML.EventName.ToString().Trim().Equals("CLICK"))
  {
  SendEventMsg(requestXML);//發(fā)送事件消息
  }
  break;

　　　　　　　　 case "voice":
  SendVoiceMsg(requestXML);//發(fā)送語音消息
  break;
  case "location"://發(fā)送位置消息
  SendMapMsg(requestXML);
  break;
  default:
  break;

 }
 }
 catch (Exception ex)
 {
 HttpContext.Current.Response.Write(ex.ToString());
 }
 }

先來關(guān)注發(fā)送文本消息，SendTextCase(requestXML);//發(fā)送文本消息

 /// <summary>
 /// 發(fā)送文本
 /// </summary>
 /// <param name="requestXML"></param>
 private void SendTextCase(RequestXML requestXML)
 {
  string responseContent = FormatTextXML(requestXML.FromUserName, requestXML.ToUserName, requestXML.Content);

  HttpContext.Current.Response.ContentType = "text/xml";
  HttpContext.Current.Response.ContentEncoding = Encoding.UTF8;
  HttpContext.Current.Response.Write(responseContent);
  HttpContext.Current.Response.End();
 }

FormatTextXML方法制定格式

 /// <summary>
 /// 返回格式化的Xml格式內(nèi)容
 /// </summary>
 /// <param name="p1">公眾號(hào)</param>
 /// <param name="p2">用戶號(hào)</param>
 /// <param name="p3">回復(fù)內(nèi)容</param>
 /// <returns></returns>
 private string FormatTextXML(string p1, string p2, string p3)
 {
 return "<xml><ToUserName><![CDATA[" + p1 + "]]></ToUserName><FromUserName><![CDATA[" + p2 + "]]></FromUserName><CreateTime>" + DateTime.Now.Subtract(new DateTime(1970, 1, 1, 8, 0, 0)).TotalSeconds.ToString() + "</CreateTime><MsgType><![CDATA[text]]></MsgType><Content><![CDATA[" + p3 + "]]></Content><FuncFlag>1</FuncFlag></xml>";
 }

這樣就能實(shí)現(xiàn)消息的應(yīng)答，如果用戶點(diǎn)擊的按鈕，如下代碼：

 case "event"://發(fā)送事件消息
  if (!string.IsNullOrWhiteSpace(requestXML.EventName) && requestXML.EventName.ToString().Trim().Equals("subscribe"))
  {
  SendWelComeMsg(requestXML);//關(guān)注時(shí)返回的圖文消息
  }
  else if (!string.IsNullOrWhiteSpace(requestXML.EventName) && requestXML.EventName.ToString().Trim().Equals("CLICK"))
  {
  SendEventMsg(requestXML);//發(fā)送事件消息
  }
  break;

 /// <summary>
 /// 發(fā)送響應(yīng)事件消息
 /// </summary>
 /// <param name="requestXML"></param>
 private void SendEventMsg(RequestXML requestXML)
 {
 string keyStr = requestXML.EventKey.ToString();

 switch (keyStr)
 {
 case "mypay":
  SendPayDetails(requestXML);//發(fā)送薪資賬單
  break;
 case "tianqiyubao":
  SendWeaterMessage(requestXML);//發(fā)送天氣預(yù)報(bào)
  break;
 case "kaixinyixiao":
  SendKaiXinMessage(requestXML);//發(fā)送開心一笑結(jié)果集
  break;
 case "updateMessage":
  SendUpdateMessage(requestXML);//發(fā)送修改信息鏈接
  break;
 case "yuangonghuodong":
  SendYuanGongHuoDong(requestXML);//發(fā)送學(xué)生活動(dòng)
  break;
 case "yuangongtongzhi":
  SendYuanGongTongZhi(requestXML);//發(fā)送員工通知
  break;
 case "youwenbida":
  SendWenti(requestXML);//發(fā)送員工提交問題鏈接
  break;
 case "mywen":
  SendWentiList(requestXML);//發(fā)送問題列表鏈接
  break;
 case "PhoneSerices":
  SendKeFuMessage(requestXML);//接入客服
  break;
 default:
  String responseContent = String.Empty;
  responseContent = FormatTextXML(requestXML.FromUserName, requestXML.ToUserName,"此功能暫未開放！敬請(qǐng)期待！");
  HttpContext.Current.Response.ContentType = "text/xml";
  HttpContext.Current.Response.ContentEncoding = Encoding.UTF8;
  HttpContext.Current.Response.Write(responseContent);
  HttpContext.Current.Response.End();
  break;
 }
 }

SendWelComeMsg(requestXML);//關(guān)注時(shí)返回的圖文消息

 /// <summary>
 /// 發(fā)送關(guān)注時(shí)的圖文消息
 /// </summary>
 /// <param name="requestXML"></param>
 private void SendWelComeMsg(RequestXML requestXML)
 {
 String responseContent = String.Empty;

 string newdate = DateTime.Now.Subtract(new DateTime(1970, 1, 1, 8, 0, 0)).TotalSeconds.ToString();


 string PUrlfileName = "http://www.deqiaohr.com.cn/weixin/welcome.jpg";

 responseContent = string.Format(Message_News_Main, requestXML.FromUserName, requestXML.ToUserName, newdate, "1",
 string.Format(Message_News_Item, "歡迎關(guān)注德橋員工服務(wù)中心", "蘇州德橋人力資源創(chuàng)立于2002年...", PUrlfileName, "http://www.deqiaohr.com.cn/weixin/WxGsjianjie.aspx"));


 HttpContext.Current.Response.ContentType = "text/xml";
 HttpContext.Current.Response.ContentEncoding = Encoding.UTF8;
 HttpContext.Current.Response.Write(responseContent);
 HttpContext.Current.Response.End();
 }

Message_News_Main 和Message_News_Item是圖文消息格式化

 /// <summary>
 /// 返回圖文消息主體
 /// </summary>
 public static string Message_News_Main
 {
 get
 {
 return @"<xml>
  <ToUserName><![CDATA[{0}]]></ToUserName>
  <FromUserName><![CDATA[{1}]]></FromUserName>
  <CreateTime>{2}</CreateTime>
  <MsgType><![CDATA[news]]></MsgType>
  <ArticleCount>{3}</ArticleCount>
  <Articles>
  {4}
  </Articles>
  </xml> ";
 }
 }
 /// <summary>
 /// 返回圖文消息項(xiàng)
 /// </summary>
 public static string Message_News_Item
 {
 get
 {
 return @"<item>
  <Title><![CDATA[{0}]]></Title> 
  <Description><![CDATA[{1}]]></Description>
  <PicUrl><![CDATA[{2}]]></PicUrl>
  <Url><![CDATA[{3}]]></Url>
  </item>";
 }
 }

 /// <summary>
 /// 發(fā)送響應(yīng)語音識(shí)別結(jié)果
 /// </summary>
 /// <param name="requestXML"></param>
 private void SendVoiceMsg(RequestXML requestXML)
 {
 string responseContent = FormatTextXML(requestXML.FromUserName, requestXML.ToUserName, "您剛才說的語音消息識(shí)別結(jié)果為：" + requestXML.Recognition.ToString());
 HttpContext.Current.Response.ContentType = "text/xml";
 HttpContext.Current.Response.ContentEncoding = Encoding.UTF8;
 HttpContext.Current.Response.Write(responseContent);
 HttpContext.Current.Response.End();
 }
