Optional query string parameters in URITemplate in WCF?
- by Shafique
I'm developing some RESTful services in WCF 4.0. I've got a method as below:
[OperationContract]
[WebGet(UriTemplate = "Test?format=XML&records={records}", ResponseFormat=WebMessageFormat.Xml)]
public string TestXml(string records)
{
return "Hello XML";
}
So if i navigate my browser to http://localhost:8000/Service/Test?format=XML&records=10, then everything works as exepcted.
HOWEVER, i want to be able to navigate to http://localhost:8000/Service/Test?format=XML and leave off the "&records=10" portion of the URL. But now, I get a service error since the URI doesn't match the expected URI template.
So how do I implement defaults for some of my query string parameters? I want to default the "records" to 10 for instance if that part is left off the query string.
