Https Session Authentication in asp.net Core

In ASP.NET Core, you can implement session-based authentication using the built-in session middleware and cookie authentication. Here's a step-by-step guide on how to set it up:

Step 1: Configure session services
In your Startup.cs file, configure the session services by adding the following code inside the ConfigureServices method:

public void ConfigureServices(IServiceCollection services)
{
    services.AddSession(options =>
    {
        // Configure session options
        options.Cookie.Name = "YourCookieName";
        options.IdleTimeout = TimeSpan.FromMinutes(30);
        options.Cookie.IsEssential = true;
    });

    services.AddControllers();
    // other services...
}

Step 2: Enable session middleware
Inside the Configure method in Startup.cs, add the session middleware after the authentication middleware:

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    // other middleware...

    app.UseAuthentication();
    app.UseAuthorization();
    app.UseSession();

    // other configuration...
}

Step 3: Configure authentication
Configure cookie authentication by adding the following code inside the ConfigureServices method in Startup.cs:

public void ConfigureServices(IServiceCollection services)
{
    // other services...

    services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
        .AddCookie(options =>
        {
            options.Cookie.Name = "YourCookieName";
            options.ExpireTimeSpan = TimeSpan.FromMinutes(30);
            options.SlidingExpiration = true;
        });

    // other services...
}

Step 4: Authenticate the user
Inside your controller or action method, you can use the HttpContext.Session property to access the session and perform authentication checks. Here's an example:

public class YourController : ControllerBase
{
    public IActionResult Authenticate(string username, string password)
    {
        // Perform your authentication logic here
        if (IsValidUser(username, password))
        {
            HttpContext.Session.SetString("Username", username);
            return Ok();
        }

        return Unauthorized();
    }

    private bool IsValidUser(string username, string password)
    {
        // Your authentication logic here
    }
}

Step 5: Restrict access to authenticated users
You can apply the [Authorize] attribute to your controller or specific action methods to restrict access to authenticated users only:

[ApiController]
[Route("api/[controller]")]
[Authorize]
public class YourController : ControllerBase
{
    // Actions...
}

These steps outline how to implement session-based authentication using cookies in ASP.NET Core. Remember to adjust the configuration and authentication logic based on your specific requirements.
