Signin Authentication Pages

Set Up the Model

Registration will be build around the following model. Add the model to your Models/ folder.

Models/SignIn.cs

No need to run a migration via Update Database as the table for this data was created in the last step.

In the pages/Secure folder, create a page called SignIn.cshtml. Do so via:

Add > Razor Page

This will create a .cshtml page and an associated .cshtml.cs page model file.

Edit the Page Model Pages/Secure/SignIn.cshtml.cs

PAGE MODEL: Pages/Secure/SignIn.cshtml.cs

public class SignInModel : PageModel
    {
        [BindProperty]
        public SignIn SignInData { get; set; }

private readonly SignInManager<AppIdentityUser> signinManager;

public SignInModel(SignInManager<AppIdentityUser> signinManager
            )
        {
            this.signinManager = signinManager;
        }

public void OnGet()
        {

}

public async Task<IActionResult> OnPostAsync()
        {
            if (ModelState.IsValid)
            {
                var result = await signinManager.PasswordSignInAsync
                (SignInData.UserName, SignInData.Password,
                    SignInData.RememberMe, false);

if (result.Succeeded)
                {
                    return RedirectToPage("/Secure/AddFilm");
                }
                else
                {
                    ModelState.AddModelError("", "Invalid user details");
                }
            }
            return Page();
        }

}

Next edit the Page Pages/Secure/SignIn.cshtml

PAGE: Pages/Secure/SignIn.cshtml

Note - this is controlled by a Cookie I think called .AspNetCore.Identity.Application. The Cookie controlling the Identity framework can be renamed in Startup.cs in the options for the ConfigureApplicationCookie using an option value of Cookie.Name
