WCF Rest不接受请求中的xml声明

Question

I am developing a WCF REST service to receive input from a third party company. It works fine if I send a plain xml-structure, but fails if the xml declaration is present in the request. Unfortunately I have no control over what is being sent, so I have to make this work WITH the declaration.

My service interface and implementation looks like this:

[ServiceContract(Namespace = "")]
public interface IService1
{
    [OperationContract]
    [WebInvoke(Method = "POST",
        ResponseFormat = WebMessageFormat.Xml,
        RequestFormat = WebMessageFormat.Xml,
        BodyStyle = WebMessageBodyStyle.Bare,
    UriTemplate = "report")]
    ResponseData Report(testclass req);
}

public class Service : IService1
{
    public string Report(testclass req)
    {
        return req.operatorStatusMessage;
    }
}

This is my testclass:

  [DataContract(Namespace = "", Name = "testclass")]
    public partial class testclass
    {
        [DataMember]
        public ushort id { get; set; }

        [DataMember]
        public byte statusCode { get; set; }

        [DataMember]
        public string statusMessage { get; set; }

        public testclass()
        { }
    }

..and this is my Web.config

 <system.serviceModel>
<services>
  <service name="SMSRep.Service" behaviorConfiguration="serviceBehavior">
    <endpoint address="" binding="webHttpBinding" contract="SMSRep.IService" behaviorConfiguration="webHttp" />
  </service>
</services>
<bindings>
  <webHttpBinding>
    <binding name="webHttpBinding" maxReceivedMessageSize="50000" />
  </webHttpBinding>
</bindings>
<behaviors>
  <serviceBehaviors>
    <behavior name="serviceBehavior">
      <serviceMetadata httpGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="false"/>
    </behavior>
  </serviceBehaviors>
  <endpointBehaviors>
    <behavior name="webHttp">
      <webHttp />
    </behavior>
  </endpointBehaviors>
</behaviors>
<serviceHostingEnvironment aspNetCompatibilityEnabled="false" multipleSiteBindingsEnabled="true"/>

The xml I am trying to send is this

<?xml version = "1.0" encoding="UTF8" ?>
<testclass>
   <id>6789</id>
   <statusCode>200</statusCode>
   <statusMessage>Some message</statusMessage>
 </testclass>

As I mentioned, without the xml declaration it works fine, if included I get an error '400 Bad Request'. The InnerException of the WebException says 'Protocol error'.

My testapp for sending looks like this:

const string url = "http://localhost:4337/Service.svc/Report";

    string txt = File.ReadAllText(xmlfile);
    byte[] requestBytes = Encoding.UTF8.GetBytes(txt);

    HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
    req.Method = "POST";
    req.ContentType = "text/xml;charset=utf-8";
    req.Timeout = 10000;
    req.ContentLength = requestBytes.Length;

    using (Stream streamWriter = req.GetRequestStream())
    {
        streamWriter.Write(requestBytes, 0, requestBytes.Length);
    }

    HttpWebResponse res = (HttpWebResponse)req.GetResponse();
    using (var streamReader = new StreamReader(res.GetResponseStream()))
    {
        var result = streamReader.ReadToEnd();
        txtReceive.Text = result;
    }

Have been Googling for days, please give me a hint someone!

Answer 1

The xml file should have the schema instance. Try adding like this

<testclass xmlns:i=\"http://www.w3.org/2001/XMLSchema-instance\">
 <id>6789</id>
 <statusCode>200</statusCode>
 <statusMessage>Some message</statusMessage>
</testclass>

Note: Remove the root xml node.

If this also fails. Try doing a data contract serialization of the contract in service using DataContractSerializer and then check if the xml string matches with what you have given in your request.
