How to access WCF service methods from a browser?

Question

This is the code that was created in Visual Studio 2013 by default. In the project properties, I decided to use Local IIS. WCF test test successfully tested. But if I access the page

http://localhost/WcfService1/Service1.svc/GetTime

in the browser, then I see a blank browser screen, and Fiddler shows "HTTP / 1.1 400 Bad Request". I understand that I need to change web.config and the attributes for the method in the interface, but I don’t know how to do it. Could you help me? Thank.

IService1.cs

using System.Runtime.Serialization;
using System.ServiceModel;
namespace WcfService1
{
    [ServiceContract]
    public interface IService1
    {
        [OperationContract]
        string GetTime();
    }
}

Service1.svc.cs

using System;
namespace WcfService1
{
    public class Service1 : IService1
    {
        public string GetTime()
        {
            return DateTime.Now.ToShortTimeString();
        }
    }
}

web.config

<?xml version="1.0"?>
<configuration>

  <appSettings>
    <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
  </appSettings>
  <system.web>
