WCF REST服务-不在合同中传递其他参数

Question

I'm about to set up a RESTful web service in WCF.

My question is how can you create a Service Host using a Service contact as the basis of the request, but also pass in additional parameters in the querystring that are not declared in the contact.

Can you access the headers to access the querystring from the service implementation? Is there a way of intercepting the request and compiling a Dictionary for the additional querystring params, and then pass this in to the operation?

Here's a sample ServiceContact I found.

[ServiceContract]
public interface ITest
{
  [OperationContract]
  [WebGet(UriTemplate = "Test?format=XML&code={code}", ResponseFormat = WebMessageFormat.Xml)]
  string TestXml(string code);
}

Taking this example I'd either need to be able to access the querystring params from the TestXml method or pass an additional dictionary/generic object as a parameter.

Thanks in advance,

Sam
