Asp.net Core Mvc Login Page Example

Log in here

As an avid programmer, I have always been fascinated by the power of web development frameworks. One framework that has caught my attention is ASP.NET Core MVC. In this article, I will walk you through an example of creating a login page using ASP.NET Core MVC. So sit back, grab your favorite coding beverage, and let’s dive into the world of ASP.NET Core MVC!

Setting up the Project

Before we get started with creating the login page, we need to set up our project. To do this, we first need to ensure that we have the necessary tools installed. Open up your command prompt and type the following command:

dotnet new mvc -n MyLoginApp

This command will create a new ASP.NET Core MVC project with the name “MyLoginApp”. Next, navigate into the project directory by typing:

cd MyLoginApp

Now that we are inside the project directory, let’s open it up in our favorite code editor. I personally prefer Visual Studio Code, but feel free to use whichever editor you are comfortable with.

Creating the Login Controller

To start creating our login page, we need to create a new controller. In ASP.NET Core MVC, controllers are responsible for handling HTTP requests and returning the appropriate response. In our case, we want to create a controller that handles the login functionality.

Inside the “Controllers” folder, create a new file called “LoginController.cs”. In this file, add the following code:

using Microsoft.AspNetCore.Mvc;

namespace MyLoginApp.Controllers
{
public class LoginController : Controller
{
public IActionResult Index()
{
return View();
}
}
}

This code defines a new controller called “LoginController” that inherits from the “Controller” class provided by ASP.NET Core MVC. Inside the controller, we have a single action method called “Index” that returns a view.

Creating the Login View

Now that we have our controller set up, let’s create the login view. Views in ASP.NET Core MVC are responsible for rendering the HTML that is sent back to the client.

Inside the “Views” folder, create a new folder called “Login”. Inside the “Login” folder, create a new file called “Index.cshtml”. In this file, add the following code:

<h2>Login</h2>

<form method="post" asp-action="Login">
<div>
<label for="username">Username:</label>
<input type="text" id="username" name="username" />
</div>
<div>
<label for="password">Password:</label>
<input type="password" id="password" name="password" />
</div>
<button type="submit">Login</button>
</form>

This code defines a simple login form with two input fields for the username and password, and a submit button. The form is set to use the “post” method and submit to the “Login” action of the “LoginController”.

Handling the Login

Now that we have our login page set up, we need to handle the login logic in our controller. In the “LoginController.cs” file, add the following code:

using Microsoft.AspNetCore.Mvc;

return RedirectToAction("Index", "Home");
}
}
}

In this code, we have added a new action method called “Login” that handles the POST request from the login form. Inside this method, you can implement your own login logic. For simplicity, we are just redirecting the user to the “Index” action of the “HomeController”.

Conclusion

In this article, we have explored how to create a login page using ASP.NET Core MVC. We started by setting up the project, then created a login controller and a login view. Finally, we handled the login logic in our controller. ASP.NET Core MVC provides a powerful and flexible framework for building web applications, and the login page example we’ve discussed here is just the tip of the iceberg. So go ahead, experiment, and unleash your creativity with ASP.NET Core MVC!
