Asp net core mvc guest page authorized pages

ASP.NET is a popular programming language used for developing web applications. It provides a powerful framework for building and websites. One common requirement in web development is to have certain pages accessible only to authorized users, while allowing guest users to access pages. In this article, we will explore how to guest pages and authorized pages in an ASP.NET Core MVC application.

To begin, let's first understand the concept of ASP.NET Core MVC. MVC stands for Model-View-Controller, which is a design used to separate the concerns of an application. The model represents the data and business logic, the view represents the user interface, and the controller handles the user and coordinates the model and view.

In an ASP.NET Core MVC application, we can define routes that map URLs to specific controllers and actions. This allows us to different pages with different functionalities. To implement guest pages and authorized pages, we can leverage the built-in authentication and authorization features of ASP.NET Core.

Guest Pages

Guest pages are accessible to all users, including those who are not authenticated. These pages typically provide general information about the website or allow users to sign up or log in. To create a guest page, we can simply define a controller action and a corresponding view.

Let's consider an example we want to create a guest page that displays general information about our website. We can define a controller action called “” in a HomeController:


public class HomeController : Controller
{
    public IActionResult Index()
    {
        return View();
    }
}

In the above code, we have defined a controller called “HomeController” that inherits from the base Controller class provided by ASP.NET Core. The “Index” action simply returns a view.

To create the corresponding view, we can add a new Razor view file called “Index.cshtml” in the “Views/Home” folder. Inside this view, we can add HTML markup to display the general information about our website.


@{
    ViewData["Title"] = "Home";
}

Welcome to our website!

This is a guest page that provides general information about our website.

In the above code, we have used Razor syntax to define the title of the page and display the welcome message.

Authorized Pages

Authorized pages, on the other hand, are accessible only to authenticated users. These pages typically contain sensitive information or provide functionality that requires user authentication. To create an authorized page, we need to implement authentication and authorization in our ASP.NET Core MVC application.

ASP.NET Core provides various authentication schemes, such as cookie authentication and JWT authentication. In this example, let's consider cookie authentication, which is a commonly used authentication scheme.

To enable cookie authentication, we need to configure it in the “Startup.cs” file. We can add the following code inside the “ConfigureServices” method:


services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
    .AddCookie(options =>
    {
        options.LoginPath = "/Account/Login";
        options.AccessDeniedPath = "/Account/AccessDenied";
    });

In the above code, we have added cookie authentication using the default authentication scheme. We have also specified the login path and access denied path, which will be used for redirecting users to the login page and access denied page, respectively.

Next, we need to decorate our authorized controller actions with the “Authorize” . This attribute ensures that only authenticated users can access the corresponding actions.

Let's consider an example where we want to create an authorized page that displays user-specific information. We can define a controller action called “Profile” in a UserController:


[Authorize]
public class UserController : Controller
{
    public IActionResult Profile()
    {
        return View();
    }
}

In the above code, we have added the “Authorize” attribute to the UserController class, which ensures that only authenticated users can access any action within this controller. The “Profile” action simply returns a view.

To create the corresponding view, we can add a new Razor view file called “Profile.cshtml” in the “Views/User” folder. Inside this view, we can add HTML markup to display the user-specific information.


@{
    ViewData["Title"] = "Profile";
}

Welcome to your profile!

This is an authorized page that displays user-specific information.

In the above code, we have used Razor syntax to define the title of the page and display the welcome message.

Conclusion

In this article, we have explored how to implement guest pages and authorized pages in an ASP.NET Core MVC application. We have seen how to create a guest page that is accessible to all users and an authorized page that is accessible only to authenticated users. By leveraging the authentication and authorization features provided by ASP.NET Core, we can easily control access to different pages based on user authentication.
