Rest APi with Post method returns "Method not allowed" error

Question

I am creating a REST API in .net with Post method as I want to extend getting data from the client ( Note I dont want to use GET method).

Here is my simple REST API which returns error " Method not allowed" . WHat is missing ??

[OperationContract]
 [WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json, UriTemplate = "/Test/{id}")]
        void Test(string id);

Url call is http://localhost/RestTestWebService.svc/json/Test/abs. This call returns Method not allowed error.

Web.config file

<system.web>
    <compilation debug="true" targetFramework="4.0" />

    <!--<authentication mode="Forms">
      <forms loginUrl="~/Account/Login.aspx" timeout="2880" />

UriTemplate must be "/Test". Your operation contract should look like:

[OperationContract]
[WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json, UriTemplate = "/Test")]
 void Test(string id);

Your URL call should be:

var myTestUrl = 'http://localhost/RestTestWebService.svc/json/Test'

You should send 'id' in the 'data' parameter of the ajax call:

$.ajax({
    url: myTestUrl,
    contentType: "application/json; charset=utf-8",
    type: 'POST',       
    data: JSON.stringify({ 'id': 12345}),
    dataType: 'json'
}).done(function (response) {
    console.log('done');
});

(Also, address="json" on service endpoint is not necessary, you can simply have adress="" and url = http://localhost/RestTestWebService.svc/Test)

UPDATE Sending the id in the url isn't incorrect, it is in my opinion not like the HTTP protocol

Thank you this works. What if the webservice for Test is Test(int i, string s) . If I use DHC Client to send the request and use the data as json string { "id":1, "i":1 } . I also tried 1,2 as data from DHC Client. – user476566 Jun 04 '14 at 14:41
Updated my answer above. Also, having an integer parameter doesn't work for me either. I send only datacontracts (objects) or string which i later on convert it to int ... not quite sure why ... yet – ralucarer Jun 04 '14 at 16:01

And also remember to add `BodyStyle = WebMessageBodyStyle.WrappedRequest` to the operation contract attributes in the case of sending multiple parametrs via POST in the message body – ralucarer Jun 04 '14 at 16:16
Thank you this has been so helpful. I was able to send int data for my Rest request , no changed needed from my end. Any suggestions for a good book on REST. – user476566 Jun 04 '14 at 17:59
I'm glad ... I don't have any books :( just killing myself over the internet too – ralucarer Jun 05 '14 at 08:21
