asp.net微信開發第三篇----自定義會話管理
和微信用戶的溝通少不了，總以爲看起來微信官網後臺管理中的會話回覆消息有點呆板，因此我這裏就自定義了一個會話管理功能，最終效果圖以下：javascript
由於我試使用富文本文件CKEDITOR來進行編寫，你看到穩中可能會有<P></p>字段，後臺獲取數據內容時，替換爲空字符便可：以下css
string txtcontent = this.txtMessage.Value.ToString().Replace("<p>", "");
StringBuilder sb = new StringBuilder();
sb.Append(txtcontent.Replace("</p>\r\n", ""));html
在我我的理解，作會話管理，無非就是將用戶對話信息（用戶發過來的數據，發給用戶的數據）存入數據庫，根據用戶的數據時間和回覆用戶數據的時間來和當天系統的時間作對比，若是大於多少分鐘或者多少個小時就不能夠再主動和用戶對話，就算我這裏是根據微信官網48小時來進行限制的，超過48小時禁用控件，以下圖：java
廢話少說，上代碼：須要用到的兩個類，數據庫也要建立和類相同的名字（至少我試這麼作的）jquery
/// <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; }//用戶內容 public string CreaterDate { get; set; }//建立時間 } /// <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; }//發送用戶 public string ToUser { get; set; }//接收用戶 public string Content { get; set; }//發送內容 public string FaSongDate { get; set; }//發送時間 public string UId { get; set; }//會話用戶的UId,微信會話記錄類外鍵 }
/// <summary> /// 發送文本。。。。。。。。。。。。。還記得這個方法嗎？就是根據用戶發送過來的消息類型進行判斷後，若是是文本就回復發送此方法內的內容 /// </summary> /// <param name="requestXML"></param> private void SendTextCase(RequestXML requestXML) { WeixinKeFuService wkfs = new WeixinKeFuService();//本身寫的服務類 //根據openId查詢數據庫會話記錄是否存在 WeixinKeFuInfo wkfinfoinfo = wkfs.GetWeixinKeFuInfoByOpenId(requestXML.FromUserName.ToString()); if (wkfinfoinfo != null) { //若是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 { //若是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(); } }
以上代碼實現了數據庫的插入，那麼取出來，顯示的頁面，核心代碼：WeiXinSessionList.aspx，前臺代碼以下：web

以上就是會話管理功能的所有核心代碼，僅供參考！另外若是因使用富文本編輯器報下列錯誤：
A potentially dangerous Request.Form value was detected from the client
解決方法：
用戶在頁面上提交表單到服務器時，服務器會檢測到一些潛在的輸入風險，例如使用富文本編輯器控件（RichTextBox、 FreeTextBox、CuteEditor等）編輯的內容中包含有HTML標記或腳本標記，ASP.NET頁面會拋出一個"A potentially dangerous Request.Form value was deceted from the client"的異常。這個是ASP.NET頁面爲了防範頁面注入功能的一種保護機制，要取消這種保護，常規的作法是在.aspx文件 的<%@Page %>部分加入ValidateRequest="false"屬性。可是從.NET 4.0開始你可能須要多修改一個地方，在網站的web.config文件中加入這行配置：
<system.web> <compilation debug="true" targetFramework="4.0"/> <httpRuntime requestValidationMode="2.0"/> </system.web>
同時，你還須要確保頁面上用戶輸入的部分不會存在任何注入攻擊的代碼，經常使用的作法是使用Encode處理。
