Role-based Authorization in ASP.NET CORE Example

March 04 2022 by Admin

In this article, we will explain how to use Role-based Authorization in ASP.NET CORE with an example and sample code.

In this article, we will explain how to use Role-based Authorization in ASP.NET CORE with Example. Here we are using Role-based Authorization to controller authorize. We have taken login page and Dashboard page for this activity only admin will access Dashboard page because we are using Role based Authorization on Controller.

Required Namespaces

We will need to use the following namespaces.

using System.Security.Claims;

using Microsoft.AspNetCore.Authentication.Cookies;

using Microsoft.AspNetCore.Authentication;

using Microsoft.AspNetCore.Http;

LoginController

we have created login controller and we are assigning Name and Role value into claims.

public class LoginController : Controller

{

public IActionResult Index()

{

return View();

}

[HttpPost]

public IActionResult Index(LoginModel loginModel)

{

var claimsIdentity = new ClaimsIdentity(new Claim[]

{

new Claim(ClaimTypes.Name, "Admin"),

new Claim(ClaimTypes.Role, "Admin")

}, CookieAuthenticationDefaults.AuthenticationScheme);

var authProperties = new AuthenticationProperties

{

IsPersistent = true,

RedirectUri = "/index"

};

HttpContext.SignInAsync(

CookieAuthenticationDefaults.AuthenticationScheme,

new ClaimsPrincipal(claimsIdentity),

authProperties);

CookieOptions option = new CookieOptions();

option.Expires = DateTime.Now.AddDays(1);

Response.Cookies.Append("UserName", $"{loginModel?.UserName}", option);

return RedirectToAction("Index", "Dashboard");

}

Index.Cshtml

We have created login html page you can see below.

@model Articles.Models.LoginModel

}

<head>

<title>User Login </title>

</head>

<label class="control-label visible-ie8 visible-ie9">Username</label>

</div>

<label class="control-label visible-ie8 visible-ie9">Password</label>

</div>

<button type="submit" class="btn green uppercase" asp-action="Index" asp-controller="Login">Login</button>

</div>

</form>

</div>

</body>

</html>

DashboardController

We have created Dashboard page only admin role can access page because we are using Role based Authorization on Controller..

[Authorize(Roles = "Admin")]

public class Dashboard : Controller

{

public IActionResult Index()

{

if (User.Identity.IsAuthenticated)

{

return Redirect("~/Dashboard/HomePage");

}

return Redirect("/Login/index");

}

public IActionResult HomePage()

{

return View();

}

HomePage.Cshtml

We have created HomePage

}

Startup.cs

We have added yellow highlight code inside Startup.cs .

public class Startup

{

public Startup(IConfiguration configuration)

{

Configuration = configuration;

}

public IConfiguration Configuration { get; }

// This method gets called by the runtime. Use this method to add services to the container.

public void ConfigureServices(IServiceCollection services)

{

services.AddMvc();

services.AddAuthentication(x =>

{

x.DefaultAuthenticateScheme = CookieAuthenticationDefaults.AuthenticationScheme;

x.DefaultChallengeScheme = CookieAuthenticationDefaults.AuthenticationScheme;

}).AddCookie(x =>

{

x.LoginPath = "/Login/index";

x.Cookie.Path = "/";

x.Cookie.HttpOnly = true;

x.ExpireTimeSpan = TimeSpan.FromMinutes(1);

x.SlidingExpiration = true;

});

}

// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.

public void Configure(IApplicationBuilder app, IHostingEnvironment env)

{

if (env.IsDevelopment())

{

app.UseDeveloperExceptionPage();

}

else

{

app.UseExceptionHandler("/Home/Error");

}

app.UseStaticFiles();

app.UseAuthentication();

app.UseMvc(routes =>

{

routes.MapRoute(

name: "default",

template: "{controller=Login}/{action=Index}/{id?}");

});

}
