Question

There is a self hosted WCF REST service, need to send an xml post message to it.
Seems like this question was asked and answered several times, but after trying every solution I still didn`t get any success.

Server: interface

[ServiceContract]
public interface ISDMobileService
{
    [OperationContract]
    [WebInvoke(Method = "POST", BodyStyle=WebMessageBodyStyle.Bare, RequestFormat = WebMessageFormat.Xml, ResponseFormat=WebMessageFormat.Xml)]
    int ProcessMessage(string inputXml);
}

Server: class

public class Service : ISDMobileService
{
    public int ProcessMessage(string inputXml)
    {
        Console.WriteLine( "ProcessMessage : " + inputXml );
        return 0;
     }  
}

Server: hosting

class Program
{
    static void Main(string[] args)
    {
        WebServiceHost          host    =   new WebServiceHost(typeof(Service), new Uri("http://172.16.3.4:7310"));
        WebHttpBinding          webbind = new WebHttpBinding(WebHttpSecurityMode.None);

        ServiceEndpoint         ep      = host.AddServiceEndpoint(typeof(ISDMobileService), webbind, "");
        ServiceDebugBehavior    stp     =   host.Description.Behaviors.Find<ServiceDebugBehavior>();
        stp.HttpsHelpPageEnabled    =   false;

        host.Open();
        Console.WriteLine("Service is up and running. Press 'Enter' to quit >>>");
        Console.ReadLine();

        host.Close();
    }
}

Request from fiddler without anything in the “Request Body” works just fine and fires break point inside ProcessMessage method of Service class, any variant of data in “Request Body”,
e.g.: test || <inputXml>test</inputXml> || inputXml=”test” || <?xml version=”1.0″ encoding=”UTF-8″ ?><inputXml>test</inputXml> etc. gives HTTP/1.1 400 Bad Request

Will appreciate any help with this

A few things:

• Since you’re using WebServiceHost, you don’t need to explicitly add the service endpoint (call to host.AddServiceEndpoint(...) in your Main.
• The operation takes a string parameter; if you want to send it in XML, you need to wrap the string in the appropriate element. Try this body and it should work:

Body:

<string xmlns="http://schemas.microsoft.com/2003/10/Serialization/">This is a string encoded in XML</string>

You can also send it in different formats, such as JSON. This request should work as well

POST http://.../ProcessMessage
Host: ...
Content-Type: application/json
Content-Length: <the actual length>

"This is a string encoded in JSON"
