How to use .net to realize the authentication function developed by Wechat public service platform

This article is about how to use .net to implement the authentication function developed by Wechat public service platform. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

.net realizes the authentication of the development of Wechat public service platform and becomes a developer. The details are as follows.

This code will be used once for authentication, and will not be used later:

Const string Token = "XXXXX"; / / your token protected void Page_Load (object sender, EventArgs e) {string postStr = ""; if (Request.HttpMethod.ToLower () = = "post") {System.IO.Stream s = System.Web.HttpContext.Current.Request.InputStream; byte [] b = new byte [s.Length]; s.Read (b, 0, (int) s.Length); postStr = System.Text.Encoding.UTF8.GetString (b) If (! string.IsNullOrEmpty (postStr)) {/ / ResponseMsg (postStr); Response.Write (ResponseMsg (postStr)); Response.End ();} / / WriteLog ("postStr:" + postStr);} else {Valid () }} / verify Wechat signature / * sort the three parameters token, timestamp and nonce in lexicographic order / * concatenate the three parameter strings into a string for sha1 encryption / * the encrypted string obtained by the developer can be compared with signature to indicate that the request originated from Wechat. / / private bool CheckSignature () {string signature = Request.QueryString ["signature"] .ToString (); string timestamp = Request.QueryString ["timestamp"] .ToString (); string nonce = Request.QueryString ["nonce"] .ToString (); string [] ArrTmp = {Token, timestamp, nonce}; Array.Sort (ArrTmp); / / in dictionary order string tmpStr = string.Join ("", ArrTmp); tmpStr = FormsAuthentication.HashPasswordForStoringInConfigFile (tmpStr, "SHA1"); tmpStr = tmpStr.ToLower () If (tmpStr = = signature) {return true;} else {return false;} .private void Valid () {string echoStr = Request.QueryString ["echoStr"] .private void Valid (); if (CheckSignature ()) {if (! string.IsNullOrEmpty (echoStr)) {Response.Write (echoStr); Response.End () }} / write log (for tracking) / private void WriteLog (string strMemo) {string filename = Server.MapPath ("/ logs/log.txt"); if (! Directory.Exists (Server.MapPath ("/ / logs//")) Directory.CreateDirectory ("/ / logs//"); StreamWriter sr = null Try {if (! File.Exists (filename)) {sr = File.CreateText (filename);} else {sr = File.AppendText (filename);} sr.WriteLine (strMemo);} catch {} finally {if (sr! = null) sr.Close ();}} Thank you for reading!
