I can able to get result ,if i called the WCF service only when i run the WCF alone.So WCF service is working fine

This a actual URL to get the Result :

http://localhost:57946/MaterialIssueService.svc/MaterialServiceJson/GetMaterialIssued/2015-01-25/2015-01-29/1/1

these are the parameters
/2015-01-25/2015-01-29/1/1

but when i make a request through AJAX,The HTTP request generating like below.

http://localhost:57946/MaterialIssueService.svc/MaterialServiceJson/GetMaterialIssued?{2015-01-25/2015-01-29/1/1}

So ,I'm not able to get a result ,How do i pass parameter ?

What I have tried:

$(function () {
           $('#btnSubmit').click(function () {
               var params = {
                   'FromDate': "2015-01-01",
                   'ToDate': "2015-01-29",
                   'PageIndex': "1",
                   'PageSize': "1"

               }
               debugger;
               $.ajax({
                   url: "http://localhost:57946/MaterialIssueService.svc/MaterialServiceJson/GetMaterialIssued",
                   type: "Get",
                   data: JSON.stringify(params),
                   dataType: "json",
                  contentType: "application/json; charset=utf-8",
                   success: function (data) {
                       if (data.status == "Success") {
                           alert("Done");

                       } else {
                           alert("Error occurs on the Database level!");
                       }
                   },
                   error: function (ex) {
                       debugger;
                       alert(ex.responseText);

                   }
               });
           });
       });
