No ajax call on WCF service with method

Question

I am sending a simple ajax call with WCF method, whenit is returning bad-request but without method it is showing status to success

Ajax Call

$(document).ready(function(){
            $.get("http://localhost:1347/Service1.svc/DoWork", //this shows bad-request
          //$.get("http://localhost:1347/Service1.svc", //this shows success
function(data, status){

                alert("Data: " + data + "\nStatus: " + status);
        });

Operation Contract

namespace WcfService1
{
    [ServiceContract]
    public interface IService1
    {
        [OperationContract]
        string DoWork();
    }
}

Implementation

public class Service1 : IService1
    {

        public string DoWork()
        {
            return string.Format("This is DoWork()");
        }
    }

Global.asax

protected void Application_BeginRequest(object sender, EventArgs e)
        {
            HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "*");
            if (HttpContext.Current.Request.HttpMethod == "OPTIONS")
            {
                HttpContext.Current.Response.AddHeader("Access-Control-Allow-Methods", "GET, POST");
                HttpContext.Current.Response.AddHeader("Access-Control-Allow-Headers", "Content-Type, Accept");
                HttpContext.Current.Response.AddHeader("Access-Control-Max-Age", "1728000");
                HttpContext.Current.Response.End();
            }
        }

First, make sure that you enable GET in your contract.

namespace WcfService1
{
    [ServiceContract]
    public interface IService1
    {
        [OperationContract]
        [WebGet(UriTemplate = "DoWork", ResponseFormat = WebMessageFormat.Json)]
        string DoWork();
    }
}

And then make sure to add webHttp in your config.

  <endpointBehaviors>
    <behavior>
      <webHttp />
    </behavior>
  </endpointBehaviors>

You also might need to set your binding to webHttpBindig .

I usually define my endpoints, but I think you can manage without it. This should be a complete example.

  <system.serviceModel>
    <services>
      <service name="WcfService1.IService1" behaviorConfiguration="myServiceBehavior">
        <endpoint address="" binding="webHttpBinding" behaviorConfiguration="myWebBehavior" contract="WcfService1.IService1" />
      </service>
    </services>
    <behaviors>
      <endpointBehaviors>
        <behavior name="myWebBehavior">
          <webHttp />
        </behavior>
      </endpointBehaviors>
      <serviceBehaviors>
        <behavior name="myServiceBehavior">
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <protocolMapping>
      <add binding="basicHttpsBinding" scheme="https"/>
    </protocolMapping>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true"/>
  </system.serviceModel>
