C#.net 微信公众账号接口开发 微信越来越火,微信公众平台成为开发成新宠,本文用C#.net开发微信公众信号接口。
微信接口地址代码:
weixin _wx = new weixin(); string postStr = ""; if (Request.HttpMethod.ToLower() == "post") { Stream s = System.Web.HttpContext.Current.Request.InputStream; byte[] b = new byte[s.Length]; s.Read(b, 0, (int)s.Length); postStr = Encoding.UTF8.GetString(b);
if (!string.IsNullOrEmpty(postStr)) //请求处理 { _wx.Handle(postStr); } } else { _wx.Auth(); }
微信处理类:public class weixin { private string Token = "weixin_token"; //换成自己的token public void Auth() { string echoStr = System.Web.HttpContext.Current.Request.QueryString["echoStr"]; if (CheckSignature()) { if (!string.IsNullOrEmpty(echoStr)) { System.Web.HttpContext.Current.Response.Write(echoStr); System.Web.HttpContext.Current.Response.End(); } } }
public void Handle(string postStr) { //封装请求类 XmlDocument doc = new XmlDocument(); doc.LoadXml(postStr); XmlElement rootElement = doc.DocumentElement;
XmlNode MsgType = rootElement.SelectSingleNode("MsgType");
RequestXML requestXML = new RequestXML(); requestXML.ToUserName = rootElement.SelectSingleNode("ToUserName").InnerText; requestXML.FromUserName = rootElement.SelectSingleNode("FromUserName").InnerText; requestXML.CreateTime = rootElement.SelectSingleNode("CreateTime").InnerText; requestXML.MsgType = MsgType.InnerText;

说明: 其中用到的mijiya类,主要是调用数据库进行关键词匹配自动回复内容,可以根据自己的业务情况编写。
