这篇文章主要介绍了C#.net 微信公众账号接口开发,需要的朋友可以参考下
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;
if (requestXML.MsgType == "text")
{
requestXML.Content = rootElement.SelectSingleNode("Content").InnerText;
}
else if (requestXML.MsgType == "location")
{
requestXML.Location_X = rootElement.SelectSingleNode("Location_X").InnerText;
requestXML.Location_Y = rootElement.SelectSingleNode("Location_Y").InnerText;
requestXML.Scale = rootElement.SelectSingleNode("Scale").InnerText;
requestXML.Label = rootElement.SelectSingleNode("Label").InnerText;
}
else if (requestXML.MsgType == "image")
{
requestXML.PicUrl = rootElement.SelectSingleNode("PicUrl").InnerText;
}
//回复消息
ResponseMsg(requestXML);
}
/// <summary>

/// </summary>
/// * 将token、timestamp、nonce三个参数进行字典序排序
/// * 将三个参数字符串拼接成一个字符串进行sha1加密

private bool CheckSignature()
{
string signature = System.Web.HttpContext.Current.Request.QueryString["signature"];
string timestamp = System.Web.HttpContext.Current.Request.QueryString["timestamp"];
string nonce = System.Web.HttpContext.Current.Request.QueryString["nonce"];
string[] ArrTmp = { Token, timestamp, nonce };
Array.Sort(ArrTmp); //字典排序
string tmpStr = string.Join("", ArrTmp);
tmpStr = FormsAuthentication.HashPasswordForStoringInConfigFile(tmpStr, "SHA1");
tmpStr = tmpStr.ToLower();
if (tmpStr == signature)
{
return true;
}
else
{
return false;
}
