Question

This problem has been presented in a number of posts in similar ways without a viable solution to mine.

My service endpoint in ManagerDiscountService looks like:

[ServiceBehavior]
[ServiceContract(Namespace = "Cart")]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class ManagerDiscountService : CartService

    [OperationContract]
    // also tried [WebInvoke(RequestFormat=WebMessageFormat.Json)]
    // also tried [WebInvoke(RequestFormat=WebMessageFormat.Json, Method="POST")]
    public MyObject ToggleMode(string userId, string pwd, string domain)

web.config:

<service name="Cart.ManagerDiscountService">
    <endpoint address="" behaviorConfiguration="Item.ItemAspNetAjaxBehavior"
     binding="webHttpBinding" bindingConfiguration="wsSecureHttp" 
     contract="Cart.ManagerDiscountService" />
</service>
<!-- tried adding a similar wsHttp binding since the POST is not SSL, no luck -->

I’m trying to post userId, pwd and domain to this endpoint, but all I see are 500’s. Why doesn’t this method of posting work? When I debug in Chrome, error is always the next execution in $.ajax:

params = { "userId": "user", "pwd": "password", "domain": "mydomain" };
$.ajax({
    type: "POST",
    url: "/Ajax/Cart/ManagerDiscountService.svc/ToggleMode",
    dataType: "json",
    data: JSON.stringify(params, null, null),
    contentType: "application/json; charset=utf-8",
    success: function (data) {
        // ...
    },
    error: function() {
        // ...
    }
});

::sigh:: this was corrected by replacing the wsSecureHttp binding with wsHttp

<endpoint address="" behaviorConfiguration="Item.ItemAspNetAjaxBehavior"
 binding="webHttpBinding" bindingConfiguration="wsHttp" 
 contract="Cart.ManagerDiscountService" />
