What is correct format for WCF PUT request?

Question

I'm struggling sending a PUT request to WCF in format that it expects. I was thinking I could send it much like a GET with a QueryString, but that just kicked back errors.

    //Put operation
    [OperationContract]
    [WebInvoke(UriTemplate = "?tid={transcriptId}&qId={quizId}&cid={choice}&mid={mbox}&status={status}", Method = "PUT", RequestFormat=WebMessageFormat.Json)]
    vTranscript UpdateTranscript(string transcriptId, string quizId, string choice, string mbox, string status);

I also tried sending as XML and JSON file using CURL, but the values from those files weren't picked up by the service (values were null).

[DataContract]
public class vTranscript
{
    [DataMember]
    public bool validUser;
    [DataMember]
    public bool correctAnswer;
    [DataMember]
    public bool recorded;
  }

I'm assuming that my vTranscript does not have to match the parameters I pass in, though I even tried that.

I'm not sure what I'm doing incorrectly. Any suggestions would be greatly appreciated. Thank you.

Try setting the bodystyle as below.

 [WebInvoke(Method = "PUT", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.WrappedRequest)]

Assuming all your parameters are posted you just need the following: (note that the posted names must match the method parameter names)

//Put operation
[OperationContract]
[WebInvoke(Method = "PUT", RequestFormat=WebMessageFormat.Json)]
vTranscript UpdateTranscript(string transcriptId, string quizId, string choice, string mbox, string status);

UriTemplate is to define parameters that are embedded in the url itself.

Thank you for your help. That worked, however now I'm getting "405 Method Not Allowed". This seems to have a lot of possible causes when I google for the error message. I'm running everything from within VS2010 so I doubt if it has to do with the cross domain issue I keep seeing. – Trebor Oct 30 '13 at 17:15
The PUT and DELETE verbs are disabled by default. This thread (http://stackoverflow.com/a/10907343/2711582) provides information on how to enable them. A workaround on the client side is to do a POST and add the X-HTTP-Method-Override header to specify the actual verb. – Wagner DosAnjos Oct 30 '13 at 18:05
After working on this some more, I was able to solve this. I was wrapping my JSON as a JSON array, and not as a simple JSON string. Thank you for your help. – Trebor Oct 30 '13 at 21:20
