微信开发通过.Net发送图文消息实例解析

这篇文章主要为大家详细解析了微信公众平台开发之发送图文消息.Net代码，感兴趣的小伙伴们可以参考一下

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/:rosen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;}以上就是微信开发通过.Net发送图文消息实例解析的详细内容，更多请关注小潘博客其它相关文章！
