  1. POAnother (400) bad request with C# REST Client: How to POST pure XML?
    text
    copied!<p>I'm having a hard time to get a simple RESTful web service application working with my C# REST client. I'm trying to send pure XML using the POST method. </p> <p>I have created a WCF Rest Service which is up and running (I can see the Service test page in my browser). Also I can call my WCF Rest Service via Fiddler and it responds correctly (I'll get a return value).</p> <p>But the big problem is the REST client. I've done everything using all kinds of guides. In addition, the same client code works with the Java-based REST service. But in .NET all I get is the error "The remote server returned an error: (400) Bad Request." This exception happens after Request.GetResponse()</p> <p>As I have developed WCF services I've used to specify configuration settings for both client (app.config) and server (web.config) but how is the situation with .NET-based RESTful web services? I mean, do I need to specify identical binding settings (webHttpBinding) for both, client (app.config) and server (web.config)?</p> <p>Here is the client-side code:</p> <pre><code>XmlDocument TestDocument = new XmlDocument(); TestDocument.Load(XMLFilePath); byte[] RequestBytes = Encoding.GetEncoding("iso-8859-1").GetBytes(TestDocument.OuterXml); Uri uri = new Uri("http://localhost:2319/MyRESTService.svc/receive"); HttpWebRequest Request = (HttpWebRequest)HttpWebRequest.Create(uri); Request.ContentLength = RequestBytes.Length; Request.Method = "POST"; Request.ContentType = "text/xml"; Stream RequestStream = Request.GetRequestStream(); RequestStream.Write(RequestBytes, 0, RequestBytes.Length); RequestStream.Close(); HttpWebResponse response = (HttpWebResponse)Request.GetResponse(); StreamReader reader = new StreamReader(response.GetResponseStream()); string ResponseMessage = reader.ReadToEnd(); response.Close(); </code></pre> <p>The web.config for my WCF REST Service looks like this (should I specify the same settings in the app.config in the C# REST client?): </p> <pre><code>&lt;system.serviceModel&gt; &lt;services&gt; &lt;service name="MyRESTService.MyRESTService"&gt; &lt;endpoint binding="webHttpBinding" contract="MyRESTService.IMyRESTService" behaviorConfiguration="webHttp"/&gt; &lt;/service&gt; &lt;/services&gt; &lt;behaviors&gt; &lt;endpointBehaviors&gt; &lt;behavior name="webHttp"&gt; &lt;webHttp/&gt; &lt;/behavior&gt; &lt;/endpointBehaviors&gt; &lt;/behaviors&gt; </code></pre> <p></p> <p>The interface for my WCF REST Service looks like this:</p> <pre><code>[ServiceContract] public interface IMyRESTService [OperationContract] [WebInvoke( Method = "POST", UriTemplate = "/receive", RequestFormat = WebMessageFormat.Xml, ResponseFormat = WebMessageFormat.Xml, BodyStyle=WebMessageBodyStyle.Bare)] string Receive(string xml); </code></pre> <p>As I understand this is a client-side problem and the exception is raised due to problems found on the client-side. But what is specifically causing this exception in my C# Rest Client? </p> <p>The XML looks like this:</p> <pre><code>&lt;?xml version="1.0" encoding="iso-8859-1"?&gt; &lt;MATMAS02&gt; &lt;IDOC BEGIN="1"&gt; &lt;EDI_DC40 SEGMENT="1"&gt; ...... </code></pre>
