(SQL Server) Duplicate TLS 1.2 SOAP Request that uses .NET HttpWebRequestThis example shows how to duplicate a SOAP request that uses .NET's HttpWebRequest and requires TLS 1.2. string xmlRequest = "...envelope..." System.Net.ServicePointManager.SecurityProtocol = (SecurityProtocolType)3072; string url = "https://www3.gsis.gr/webtax2/wsgsis/RgWsPublic/RgWsPublicPort?WSDL"; HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url); req.Method = "POST"; req.ContentType = "text/xml;charset=UTF-8"; byte[] reqBytes = new System.Text.UTF8Encoding().GetBytes(xmlRequest); req.ContentLength = reqBytes.Length; try { using (System.IO.Stream reqStream = req.GetRequestStream()) { reqStream.Write(reqBytes, 0, reqBytes.Length); reqStream.Flush(); reqStream.Close(); } } catch (Exception ex) { actionLogger.AddError(ex.Message, null); actionLogger.Validate(); } string xmlResponse = null; using (HttpWebResponse resp = (HttpWebResponse)req.GetResponse()) { try { using (System.IO.StreamReader sr = new System.IO.StreamReader(resp.GetResponseStream())) { xmlResponse = sr.ReadToEnd(); sr.Close(); } } catch (Exception ex) { actionLogger.AddError(ex.Message, null); actionLogger.Validate(); } finally { resp.Close(); } } Note: This example requires Chilkat v11.0.0 or greater.
