微信公众平台开发之发送图文消息.Net代码解析


            之前我们讲过让微信发送给我们普通的文本信息,下面我们来看看如何发送图文信息,需要注意的是这里说的是,让微信发给我们,而不是我们拍个图片发给微信处理,我们上传图片在以后的章节介绍.下面是发送图文消息的函数,涉及title(标题),description(摘要),picurl(图片),链接(url)几个关键的参数: 







protected string sendPicTextMessage(Msg _mode,string title,string description,string picurl,string url)

  {

    

    string res = string.Format(@"<xml>

    <ToUserName><![CDATA[{0}]]></ToUserName>

    <FromUserName><![CDATA[{1}]]></FromUserName>

    <CreateTime>{2}</CreateTime>

    <MsgType><![CDATA[news]]></MsgType>

    <ArticleCount>1</ArticleCount>

    <Articles>

     <item>

     <Title><![CDATA[{3}]]></Title> 

     <Description><![CDATA[{4}]]></Description>

     <PicUrl><![CDATA[{5}]]></PicUrl>

     <Url><![CDATA[{6}]]></Url>

     </item>

     </Articles>

     </xml> ",

      _mode.FromUserName, _mode.ToUserName, DateTime.Now,title, description, picurl, url);



    return res;



   }







直接在调用函数即可: 









protected void Page_Load(object sender, EventArgs e)

   {

    

     MyMenu();

     wxmessage wx = GetWxMessage();

     string res = "";



     if (!string.IsNullOrEmpty(wx.EventName) && wx.EventName.Trim() == "subscribe")

     {

       string content = "";

       content = "/:rose欢迎北京永杰友信科技有限公司/:rose\n直接回复“你好”";

       res = sendTextMessage(wx, content);

     }

     else if (!string.IsNullOrEmpty(wx.EventName) && wx.EventName.Trim() == "CLICK")

     {

       if(wx.EventKey=="Hello")

         res = sendTextMessage(wx, "你好,欢迎使用北京永杰友信科技有限公司公共微信平台!");

       if(wx.EventKey=="P1")

         res = sendTextMessage(wx, "你好,点击了产品1");

       if(wx.EventKey=="P2")

         res = sendTextMessage(wx, "你好,点击了产品2");

     }

     else

     {

       if (wx.MsgType == "text" && wx.Content == "你好")

       {

         res = sendTextMessage(wx, "你好,欢迎使用北京永杰友信科技有限公司公共微信平台!");

       }

       if (wx.MsgType == "text" && wx.Content == "图文")

       {

         res = sendPicTextMessage(wx,"这里是一个标题","这里是摘要","http://mp.weixin.qq.com/wiki/skins/common/images/weixin_wiki_logo.png","http://www.4ugood.net");

       }

       else if (wx.MsgType == "voice")

       {

         res = sendTextMessage(wx, wx.Recognition);

       }

       else

       {

         res = sendTextMessage(wx, "你好,未能识别消息!");

       }

     }



     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;

       wx.EventKey = xml.SelectSingleNode("xml").SelectSingleNode("EventKey").InnerText;

     }

     if (wx.MsgType.Trim() == "voice")

     {

       wx.Recognition = xml.SelectSingleNode("xml").SelectSingleNode("Recognition").InnerText;

     }

     

     return wx;

   }
