asp.net微信開發(fā)（自定義會話管理）

更新時間：2015年11月17日 15:46:01 作者：將哥

這篇文章主要介紹了asp.net微信開發(fā)中有關(guān)自定義會話管理的相關(guān)內(nèi)容，需要的朋友可以參考下

和微信用戶的溝通少不了，總覺得看起來微信官網(wǎng)后臺管理中的會話回復(fù)消息有點呆板，所以我這里就自定義了一個會話管理功能，最終效果圖如下：

因為我試使用富文本文件CKEDITOR來進行編寫，你看到穩(wěn)中可能會有<P></p>字段，后臺獲取數(shù)據(jù)內(nèi)容時，替換為空字符即可：如下

 string txtcontent = this.txtMessage.Value.ToString().Replace("<p>", "");
   StringBuilder sb = new StringBuilder();
   sb.Append(txtcontent.Replace("</p>\r\n", ""));

在我個人理解，做會話管理，無非就是將用戶對話信息（用戶發(fā)過來的數(shù)據(jù)，發(fā)給用戶的數(shù)據(jù)）存入數(shù)據(jù)庫，根據(jù)用戶的數(shù)據(jù)時間和回復(fù)用戶數(shù)據(jù)的時間來和當(dāng)天系統(tǒng)的時間做對比，如果大于多少分鐘或者多少個小時就不可以再主動和用戶對話，就算我這里是根據(jù)微信官網(wǎng)48小時來進行限制的，超過48小時禁用控件，如下圖：

廢話少說，上代碼：需要用到的兩個類，數(shù)據(jù)庫也要創(chuàng)建和類相同的名字（至少我試這么做的）

/// <summary>
 /// 微信會話記錄類，用戶存儲會話記錄列表
 /// </summary>
 public class WeixinKeFuInfo
 {
 public int UId { get; set; }//編號
 public string UserOpenId { get; set; }//用戶的OpenID
 public string UserContent { get; set; }//用戶內(nèi)容
 public string CreaterDate { get; set; }//創(chuàng)建時間
 }

 

 /// <summary>
 /// 與微信用戶會話的消息記錄類
 /// </summary>
 public class WxMessageInfo
 {
 public int msgId { get; set; }//消息ID
 public string FromUser { get; set; }//發(fā)送用戶
 public string ToUser { get; set; }//接收用戶
 public string Content { get; set; }//發(fā)送內(nèi)容
 public string FaSongDate { get; set; }//發(fā)送時間
 public string UId { get; set; }//會話用戶的UId,微信會話記錄類外鍵
 }

 /// <summary>
 /// 發(fā)送文本。。。。。。。。。。。。。還記得這個方法嗎？就是根據(jù)用戶發(fā)送過來的消息類型進行判斷后，如果是文本就回復(fù)發(fā)送此方法內(nèi)的內(nèi)容
 /// </summary>
 /// <param name="requestXML"></param>
 private void SendTextCase(RequestXML requestXML)
 {

　　　　 　WeixinKeFuService wkfs = new WeixinKeFuService();//自己寫的服務(wù)類
  //根據(jù)openId查詢數(shù)據(jù)庫會話記錄是否存在
  WeixinKeFuInfo wkfinfoinfo = wkfs.GetWeixinKeFuInfoByOpenId(requestXML.FromUserName.ToString());
  if (wkfinfoinfo != null)
  {
   //如果存在直接保存消息記錄
   WxMessageService wms = new WxMessageService();
   WxMessageInfo wminfo = new WxMessageInfo();
   wminfo.FromUser = requestXML.FromUserName.ToString();
   wminfo.ToUser = "我";
   wminfo.Content = requestXML.Content.ToString();
   wminfo.FaSongDate = System.DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss");
   wminfo.UId = wkfinfoinfo.UId.ToString();
   wms.AddWxMessageInfo(wminfo);
  }
  else
  {
   //如果不存在新建會話記錄
   WeixinKeFuInfo wkfinfo = new WeixinKeFuInfo();
   wkfinfo.UserOpenId = requestXML.FromUserName.ToString();
   wkfinfo.UserContent = requestXML.Content.ToString();
   wkfinfo.CreaterDate = System.DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss");
   wkfs.AddWeixinKeFuInfo(wkfinfo);

   string responseContent = FormatTextXML(requestXML.FromUserName, requestXML.ToUserName, "正在接入.請稍候.....");

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

　　}

以上代碼實現(xiàn)了數(shù)據(jù)庫的插入，那么取出來，顯示的頁面，核心代碼：WeiXinSessionList.aspx，前臺代碼如下：
