C#.net 微信公眾賬號接口開發(fā)_

1、C#.net 微信公眾賬號接口開發(fā)_ 微信越來越火，微信公眾平臺成為開發(fā)成新寵，本文用C#.net開發(fā)微信公眾信號接口。 微信接口地址代碼: weixin _wx = new weixin(); string postStr = ; if (Request.HttpMethod.ToLower() = post) Stream s = System.Web.HttpContext.Current.Request.InputStream; byte b = new bytes.Length; s.Read(b, 0, (int)s.Length); postStr = Encoding.UTF8

2、.GetString(b); if (!string.IsNullOrEmpty(postStr) /懇求處理 _wx.Handle(postStr); else _wx.Auth(); 微信處理類： public class weixin private string Token = weixin_token; /換成自己的token public void Auth() string echoStr = System.Web.HttpContext.Current.Request.QueryStringechoStr; if (CheckSignature() if (!string.Is

3、NullOrEmpty(echoStr) System.Web.HttpContext.Current.Response.Write(echoStr); System.Web.HttpContext.Current.Response.End(); public void Handle(string postStr) /封裝懇求類 XmlDocument doc = new XmlDocument(); doc.LoadXml(postStr); XmlElement rootElement = doc.DocumentElement; XmlNode MsgType = rootElement

4、.SelectSingleNode(MsgType); RequestXML requestXML = new RequestXML(); requestXML.ToUserName = rootElement.SelectSingleNode(ToUserName).InnerText; requestXML.FromUserName = rootElement.SelectSingleNode(FromUserName).InnerText; requestXML.CreateTime = rootElement.SelectSingleNode(CreateTime).InnerText

5、; 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.Selec

6、tSingleNode(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; /回復消息 ResponseMsg(requestXML

7、); / summary / 驗證微信簽名 / /summary / * 將token、timestamp、nonce三個參數進行字典序排序 / * 將三個參數字符串拼接成一個字符串進行sha1加密 / * 開發(fā)者獲得加密后的字符串可與signature對比，標識該懇求來源于微信。 / returns/returns private bool CheckSignature() string signature = System.Web.HttpContext.Current.Request.QueryStringsignature; string timestamp = System.Web.

8、HttpContext.Current.Request.QueryStringtimestamp; string nonce = System.Web.HttpContext.Current.Request.QueryStringnonce; string ArrTmp = Token, timestamp, nonce ; Array.Sort(ArrTmp); /字典排序 string tmpStr = string.Join(, ArrTmp); tmpStr = FormsAuthentication.HashPasswordForStoringInConfigFile(tmpStr,
