ASP.NET MVC5: Role Base Accessibility

Role base accessibility is another integral part of web development because it provides encapsulation for designated information accessibility to designated credential.
Microsoft MVC paradigm provides a very simple and effective mechanism to achieve role base accessibility. So, for today's discussion, I will be demonstrating role base accessibility using ASP.NET MVC5 technology.


Following are some prerequisites before you proceed any further in this tutorial:

Prerequisites: 

1) Knowledge about ASP.NET MVC5.  
2) Knowledge about ADO.NET.
3) Knowledge about entity framework.
4) Knowledge about OWIN.
5) Knowledge about Claim Base Identity Model.
6) Knowledge about C# programming.
7) Knowledge about C# LINQ.

You can download the complete source code for this tutorial or you can follow the step by step discussion below. The sample code is developed in Microsoft Visual Studio 2013 Ultimate. I am using SQL Server 2008 as database.

Download Now!

Let's Begin now.

1) First you need to create a sample database with "Login" & "Role" tables, I am using following scripts to generate my sample database. My database name is "RoleBaseAccessibility", below is the snippet for it:


USE [RoleBaseAccessibility]  
 GO  
 /****** Object: ForeignKey [R_10]  Script Date: 04/30/2016 16:32:55 ******/  
 IF EXISTS (SELECT * FROM sys.foreign_keys WHERE object_id = OBJECT_ID(N'[dbo].[R_10]') AND parent_object_id = OBJECT_ID(N'[dbo].[Login]'))  
 ALTER TABLE [dbo].[Login] DROP CONSTRAINT [R_10]  
 GO  
 /****** Object: StoredProcedure [dbo].[LoginByUsernamePassword]  Script Date: 04/30/2016 16:32:59 ******/

 GO  

Here I have created a simple login & role tables with sample data and a store procedure to retrieve the data.

2) Create new visual studio web MVC project and name it "RoleBaseAccessibility".  
3) You need to create database connectivity using "Entity Framework Database First Approach". You can visit here for details.  
4) You also need to create basic "Login" interface, I am not going to show you how you can create a basic login application by using Claim Base Identity Model. You can either download source code for this tutorial or you can go through detail tutorial here for better understanding.  
5) Now, open "App_Start->Startup.Auth.cs" file and replace it with following code:
 
using Microsoft.AspNet.Identity;  
 using Microsoft.AspNet.Identity.EntityFramework;  
 using Microsoft.AspNet.Identity.Owin;  
 using Microsoft.Owin;  
 using Microsoft.Owin.Security.Cookies;  
 using Microsoft.Owin.Security.DataProtection;  
 using Microsoft.Owin.Security.Google;  
 using Owin;  
 using System;  
 using RoleBaseAccessibility.Models;  
 namespace RoleBaseAccessibility  
 {  
   public partial class Startup  
   {  
     // For more information on configuring authentication, please visit http://go.microsoft.com/fwlink/?LinkId=301864  
     public void ConfigureAuth(IAppBuilder app)  
     {  
       // Enable the application to use a cookie to store information for the signed in user  
       // and to use a cookie to temporarily store information about a user logging in with a third party login provider  
       // Configure the sign in cookie  
       app.UseCookieAuthentication(new CookieAuthenticationOptions  
       {  
         AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,  
         LoginPath = new PathString("/Account/Login"),  
         LogoutPath = new PathString("/Account/LogOff"),  
         ExpireTimeSpan = TimeSpan.FromMinutes(5.0),  
         ReturnUrlParameter = "/Home/Index"  
       });  
       app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);  
       // Uncomment the following lines to enable logging in with third party login providers  
       //app.UseMicrosoftAccountAuthentication(  
       //  clientId: "",  
       //  clientSecret: "");  
       //app.UseTwitterAuthentication(  
       //  consumerKey: "",  
       //  consumerSecret: "");  
       //app.UseFacebookAuthentication(  
       //  appId: "",  
       //  appSecret: "");  
       //app.UseGoogleAuthentication(new GoogleOAuth2AuthenticationOptions()  
       //{  
       //  ClientId = "",  
       //  ClientSecret = ""  
       //});  
     }  
   }  
 }  

In above code following line of code will redirect the user to home page if he/she tries to access a link which is not authorized to him/her:


ReturnUrlParameter = "/Home/Index"

6) Create new controller, name it "AccountController.cs" under "Controller" folder and replace it with following code:

     #endregion  
     #endregion  
   }  
 }  

In above code, following piece of code is important i.e.


   #region Sign In method.  
     /// <summary>  
     /// Sign In User method.  
     /// </summary>  
     /// <param name="username">Username parameter.</param>

     private void SignInUser(string username, int role_id, bool isPersistent)  
     {  
       // Initialization.  
       var claims = new List<Claim>();  
       try  
       {  
         // Setting  
         claims.Add(new Claim(ClaimTypes.Name, username));  
         claims.Add(new Claim(ClaimTypes.Role, role_id.ToString()));  
         var claimIdenties = new ClaimsIdentity(claims, DefaultAuthenticationTypes.ApplicationCookie);  
         var ctx = Request.GetOwinContext();  
         var authenticationManager = ctx.Authentication;  
         // Sign In.  
         authenticationManager.SignIn(new AuthenticationProperties() { IsPersistent = isPersistent }, claimIdenties);  
       }  
       catch (Exception ex)  
       {  
         // Info  
         throw ex;  
       }  
     }  
     #endregion  

Here, along with claiming "Username" in OWIN security layer, we are also claiming "role_id" to provide role base accessibility:


claims.Add(new Claim(ClaimTypes.Role, role_id.ToString()));  

7) Now, create new controller under "Controller" folder, name it "HomeController.cs" and replace it with following code i.e.


// <copyright file="HomeController.cs" company="None">  
 //   Copyright (c) Allow to distribute this code.  
 // </copyright>  
 // <author>Asma Khalid</author>  
 //-----------------------------------------------------------------------  
 namespace RoleBaseAccessibility.Controllers  
 {  
   using System;  
   using System.Collections.Generic;  
   using System.Linq;  
   using System.Web;  
   using System.Web.Mvc;  
   /// <summary>  
   /// Home controller class.  
   /// </summary>  
   [Authorize]  
   public class HomeController : Controller  
   {  
     #region Index method.  
     /// <summary>  
     /// Index method.  
     /// </summary>  
     /// <returns>Returns - Index view</returns>  
     public ActionResult Index()  
     {  
       return this.View();  
     }  
     #endregion  
     #region Admin Only Link  
     /// <summary>  
     /// Admin only link method.  
     /// </summary>  
     /// <returns>Returns - Admin only link view</returns>  
     [Authorize(Roles = "1")]  
     public ActionResult AdminOnlyLink()  
     {  
       return this.View();  
     }  
     #endregion  
   }  
 }  

In above code, we have simply created two views, one is accessible to all the user which is "Index" view and second method is accessible to only "Admin" role user with role_id = 1. Following piece of code will translate the role base accessibility in OWIN security layer i.e.


[Authorize(Roles = "1")]  

If you want to define role accessibility for multiple roles you can achieve it like following:


[Authorize(Roles = "1, 2, 3")]  

where, 2, 3 are role id(s). 8) Replace following code in "_LoginPartial.cshtml" file:


@*@using Microsoft.AspNet.Identity*@  
 @if (Request.IsAuthenticated)  
 {  
   using (Html.BeginForm("LogOff", "Account", FormMethod.Post, new { id = "logoutForm", @class = "navbar-right" }))  
   {  
     @Html.AntiForgeryToken()  
     <ul class="nav navbar-nav navbar-right">  
       @if (Convert.ToInt32(this.Session["role_id"]) == 1)  
       {   
         <li>  
           @Html.ActionLink("Admin Only Link", "AdminOnlyLink", "Home")  
         </li>  
       }  
       <li>  
         @Html.ActionLink("Hello " + User.Identity.Name + "!", "Index", "Home", routeValues: null, htmlAttributes: new { title = "Manage" })  
       </li>  
       <li><a href="javascript:document.getElementById('logoutForm').submit()">Log off</a></li>  
     </ul>  
   }  
 }  
 else  
 {  
   <ul class="nav navbar-nav navbar-right">  
     <li>@Html.ActionLink("Log in", "Login", "Account", routeValues: null, htmlAttributes: new { id = "loginLink" })</li>  
   </ul>  
 }  
   
9) Execute the project and you will see following:
 

10) When you login as admin account you will able to see a link that only admin can see as follow:



11) When you login as non-admin account you won't see the link that admin can see but, if you try to open the link which supposedly you do not have access of, you will be redirected to your home page as follow:



That's about it!!

Enjoy coding!!!
