這篇文章主要為大家詳細(xì)解析了微信公眾平臺(tái)開發(fā)之發(fā)送圖文消息.Net代碼，感興趣的小伙伴們可以參考一下
之前我們講過讓微信發(fā)送給我們普通的文本信息,下面我們來看看如何發(fā)送圖文信息,需要注意的是這里說的是,讓微信發(fā)給我們,而不是我們拍個(gè)圖片發(fā)給微信處理,我們上傳圖片在以后的章節(jié)介紹.下面是發(fā)送圖文消息的函數(shù),涉及title(標(biāo)題),description(摘要),picurl(圖片),鏈接(url)幾個(gè)關(guān)鍵的參數(shù):
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;
}
直接在調(diào)用函數(shù)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 (!string.IsNullOrEmpty(wx.EventName) && wx.EventName.Trim() == "CLICK")
{
if(wx.EventKey=="Hello")
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(tái)!");
if(wx.EventKey=="P1")
res = sendTextMessage(wx, "你好,點(diǎn)擊了產(chǎn)品1");
if(wx.EventKey=="P2")
res = sendTextMessage(wx, "你好,點(diǎn)擊了產(chǎn)品2");
}
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(tái)!");
}
if (wx.MsgType == "text" && wx.Content == "圖文")
{
res = sendPicTextMessage(wx,"這里是一個(gè)標(biāo)題","這里是摘要","http://pic02.newdu.com/uploads/202504/02/weixin_wiki_logo2812.png","http://www.4ugood.net");
}
else if (wx.MsgType == "voice")
{
res = sendTextMessage(wx, wx.Recognition);
}
else
{
res = sendTextMessage(wx, "你好,未能識(shí)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;
wx.EventKey = xml.SelectSingleNode("xml").SelectSingleNode("EventKey").InnerText;
}
if (wx.MsgType.Trim() == "voice")
{
wx.Recognition = xml.SelectSingleNode("xml").SelectSingleNode("Recognition").InnerText;
}
return wx;
}
