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 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.jpg","http://www.4ugood"); } 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; }
