這篇文章詳解微信公眾平臺開發(fā)之發(fā)送文本消息.Net代碼解析方法

.Net實現(xiàn)微信公共服務(wù)平臺開發(fā)中的發(fā)送文本消息功能，具體內(nèi)容如下

首先建立一個微信消息類。?

class wxmessage 
{ 
 public string FromUserName { get; set; } 
 public string ToUserName { get; set; } 
 public string MsgType { get; set; } 
 public string EventName { get; set; } 
 public string Content { get; set; }
 public string EventKey { get; set; } 
}

后臺代碼如下：

protected void Page_Load(object sender, EventArgs e)
  {
   wxmessage wx = GetWxMessage();
   string res = "";
 
   if (!string.IsNullOrEmpty(wx.EventName) && wx.EventName.Trim() == "subscribe")
   {//剛關(guān)注時的時間，用于歡迎詞
    string content = "";
    content = "/:rose歡迎北京永杰友信科技有限公司/:rose\n直接回復(fù)“你好”";
    res = sendTextMessage(wx, content);
   }
   else
   {
    if (wx.MsgType == "text" && wx.Content == "你好")
    {
     res = sendTextMessage(wx, "你好,歡迎使用北京永杰友信科技有限公司公共微信平臺!");
    }
    else
    {
     res = sendTextMessage(wx, "你好,未能識別消息!");
    }
   }
 
   Response.Write(res);
  }
 
 private wxmessage GetWxMessage()
  {
   wxmessage wx = new wxmessage();
   StreamReader str = new StreamReader(Request.InputStream, System.Text.Encoding.UTF8);
   XmlDocument xml = new XmlDocument();
   xml.Load(str);
   wx.ToUserName = xml.SelectSingleNode("xml").SelectSingleNode("ToUserName").InnerText;
   wx.FromUserName = xml.SelectSingleNode("xml").SelectSingleNode("FromUserName").InnerText;
   wx.MsgType = xml.SelectSingleNode("xml").SelectSingleNode("MsgType").InnerText;
   if (wx.MsgType.Trim() == "text")
   {
    wx.Content = xml.SelectSingleNode("xml").SelectSingleNode("Content").InnerText;
   }
   if (wx.MsgType.Trim() == "event")
   {
    wx.EventName = xml.SelectSingleNode("xml").SelectSingleNode("Event").InnerText;
   }
 
    
   return wx;
  }
 
/// 
  /// 發(fā)送文字消息 
  /// 
  /// 獲取的收發(fā)者信息 
  /// 內(nèi)容 
  /// 
  private string sendTextMessage(wxmessage wx, string content)
  {
   string res = string.Format(@" ",
    wx.FromUserName, wx.ToUserName, DateTime.Now, content);
   return res;
  }
