如何在WCF REST服务中使用可选参数？

Question

What I am looking for is a way I can pass anything to a specific url so I can parse it myself. Something like this :

    [OperationContract]
    [WebGet(UriTemplate = "/whatever/blabla/{query}", RequestFormat = WebMessageFormat.Xml)]
    string AddRouteForUser(string query);

Afterwards I can parse query myself to have the values I need. Is it possible ? Is there a better way ?

Thanks

Answer 1

One option would be to use query string params since by definition, they're sort of an optional property bag of options tagged onto a query. That leaves the path to being an immutable identifier for your rest resource.

/whatever/blabla?some=data&whichis=optional

It's hard to say though without sepcific knowledge of the data and the rest resources

EDIT:

QueryStrings can be optional.
See comment from Anand @ https://connect.microsoft.com/VisualStudio/feedback/details/451296/rest-wcf-uritemplate-optional-querystring-parameters

"You can get the desired effect by omitting the Query string from the UriTemplate on your WebGet or WebInvoke attribute, and using WebOperationContext.Current.IncomingRequest.UriTemplateMatch.QueryParameters"

Answer 2

At the end I am going to use OperationContext to get the complete url and parse it myself. I just put in WebGet this /whatever/{query} so I know what I want to treat.
