I got a mail asking question, “How could we remove .SVC from a WCF REST Service?

For example, instead of

clip_image001

We need to remove, .svc extension from address of the WCF service.

Let us say, you have a WCF REST Service up and running

http://localhost:58230/Service1.svc/GetMessage

With output

clip_image003

Read here: How to create a WCF REST Service

To remove service extension, we will write a HTTP Module and remove the extension and rewrite the path.

Now to remove .svc follows below steps

1. Add a class in WCF Application project.

2. Add the namespace System.Web

3. Implement the class from IHttpModule

4. Before starting of current context take the context path and rewrite the URL.

Full source code for

RemoveSvc.cs


using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace WcfService7
{
    public class Removesvc : IHttpModule
    {
        public void Dispose()
        {
        }
        public void Init(HttpApplication context)
        {
            context.BeginRequest += delegate
            {
                HttpContext cxt = HttpContext.Current;
                string path = cxt.Request.AppRelativeCurrentExecutionFilePath;
                int i = path.IndexOf('/', 2);
                if (i > 0)
                {
                    string a = path.Substring(0, i) + ".svc";
                    string b = path.Substring(i, path.Length - i);
                    string c = cxt.Request.QueryString.ToString();
                    cxt.RewritePath(a, b, c, false);
                }
            };
        }
    }
}

5. Now we need to add the HTTP Module in configuration file of WCF Service.

clip_image008

Where, RemoveSvc is name of the class implementing IHttpModule and WcfService7 is the project name (namespace)

Web.Config


<?xml version="1.0"?>
<configuration>
  <system.web>
    <compilation debug="true" targetFramework="4.0" />
  </system.web>
  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
          <serviceMetadata httpGetEnabled="true"/>
          <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
  </system.serviceModel>
 <system.webServer>
    <modules>
      <add name ="removesvc" type ="WcfService7.Removesvc,WcfService7"/>
   </modules>      
  </system.webServer
</configuration>


6. Now host the service in IIS. [Read here : Hosting WCF Service in IIS ]

Now when you open WCF REST Service in browser, you can see you are able to call the service without extension ,

http://localhost:4567/Service1/GetMessage
