微信公共平台开发-(.net实现)4--发送图文消息
之前说了让微信发送给关注我们的粉丝普通的文本信息,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,上传图片在以后的再讲.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:
格式如下:(此为多图文形式)
其实格式呢就和上篇http://www.cnblogs.com/QLJ1314/p/3855371.html格式一样。
1 protected string sendPicTextMessage(Msg _mode,string title,string description,string picurl,string url) 2 { 3 4 string res = string.Format(@"<xml> 5 <ToUserName><![CDATA[{0}]]></ToUserName> 6 <FromUserName><![CDATA[{1}]]></FromUserName> 7 <CreateTime>{2}</CreateTime>//时间,可以转成int类型,类似与时间戳 8 <MsgType><![CDATA[news]]></MsgType> 9 <ArticleCount>1</ArticleCount>//数量 10 <Articles> 11 <item> 12 <Title><![CDATA[{3}]]></Title> //图文标题 13 <Description><![CDATA[{4}]]></Description>//图文描述 14 <PicUrl><![CDATA[{5}]]></PicUrl>//图片路径 15 <Url><![CDATA[{6}]]></Url>//链接地址 16 </item> 17 </Articles> 18 </xml> ", 19 _mode.FromUserName, _mode.ToUserName, DateTime.Now,title, description, picurl, url); 20 21 return res; 22 23 }
1 protected void Page_Load(object sender, EventArgs e) 2 { 3 4 MyMenu(); 5 wxmessage wx = GetWxMessage(); //获取微信所需信息 6 string res = ""; 7 8 if (!string.IsNullOrEmpty(wx.EventName) && wx.EventName.Trim() == "subscribe") //关注事件 9 { 10 string content = ""; 11 content = "你好,感谢你关注QLJ1314博客"; 12 res = sendTextMessage(wx, content); 13 } 14 else if (!string.IsNullOrEmpty(wx.EventName) && wx.EventName.Trim() == "CLICK") 15 { 16 if(wx.EventKey=="Hello") 17 res = sendTextMessage(wx, "请说中文!"); 18 if(wx.EventKey=="P1") 19 res = sendTextMessage(wx, "你好,点击了我的博文1"); 20 } 21 else 22 { 23 if (wx.MsgType == "text" && wx.Content == "你好") 24 { 25 res = sendTextMessage(wx, "你好,感谢你关注QLJ1314博客"); 26 } 27 if (wx.MsgType == "text" && wx.Content == "图文") //此为图文回复 28 { 29 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"); 30 } 31 else if (wx.MsgType == "voice") //此为语音回复,稍后讲或者直接看开发者文档自己试试 32 { 33 res = sendTextMessage(wx, wx.Recognition); 34 } 35 else 36 { 37 res = sendTextMessage(wx, "你好,未能识别消息!"); 38 } 39 } 40 41 Response.Write(res); 42 }
1 private wxmessage GetWxMessage() 2 { 3 wxmessage wx = new wxmessage(); //实例化微信类 4 StreamReader str = new StreamReader(Request.InputStream, System.Text.Encoding.UTF8); 5 XmlDocument xml = new XmlDocument(); //实例化微信的xml类 6 xml.Load(str); //读取数据流 7 //取所需的节点值 8 wx.ToUserName = xml.SelectSingleNode("xml").SelectSingleNode("ToUserName").InnerText; 9 wx.FromUserName = xml.SelectSingleNode("xml").SelectSingleNode("FromUserName").InnerText; 10 wx.MsgType = xml.SelectSingleNode("xml").SelectSingleNode("MsgType").InnerText; 11 if (wx.MsgType.Trim() == "text") //文本类型 12 { 13 wx.Content = xml.SelectSingleNode("xml").SelectSingleNode("Content").InnerText; 14 } 15 if (wx.MsgType.Trim() == "event") //事件,关注 16 { 17 wx.EventName = xml.SelectSingleNode("xml").SelectSingleNode("Event").InnerText; 18 wx.EventKey = xml.SelectSingleNode("xml").SelectSingleNode("EventKey").InnerText; 19 } 20 if (wx.MsgType.Trim() == "voice") //语音 21 { 22 wx.Recognition = xml.SelectSingleNode("xml").SelectSingleNode("Recognition").InnerText; 23 } 24 25 return wx; 26 }
写了这么多了,相信你也能照葫芦画瓢接着往下进行回复语音消息、视频、音乐消息喽,或者是再深一点的,相信自己,一定能成功,可以大胆尝试一下。
