How to login user based on email and password? - asp.net-mvc

Question

I am trying to create a login page and struggling to find a solution. Here is what I have so far. I have tried to different things like use passwordAsync and EmailAsync but not working. I am using entity core framework.
Controller
public class AccountController : Controller
{
private readonly SignUpContext _signUp;
private readonly LoginContext _login;
public AccountController(SignUpContext signUp, LoginContext login)
{
_signUp = signUp;
_login = login;
}
[HttpGet]
public IActionResult Login()
{
return View();
}
[HttpPost]
[ValidateAntiForgeryToken]
public IActionResult Login(Login login)
{
if (ModelState.IsValid)
{
}
return View(login);
}
[HttpGet]
public IActionResult SignUp()
{
return View();
}
[HttpPost]
public async Task<IActionResult> SignUp([Bind("UserID,FirstName,LastName,Address1,Address2,City,State,Zipcode,Phone,Email,Password")]SignUp users)
{
if (ModelState.IsValid)
{
_signUp.Add(users);
await _signUp.SaveChangesAsync();
return RedirectToAction("Login");
}
return View(users);
}
}
}

Answer 1

Kindly provide the code you are trying to do the authentication inside ModelState.IsValid
[HttpPost]
[ValidateAntiForgeryToken]
public IActionResult Login(Login login)
{
if (ModelState.IsValid)
{
}
return View(login);
}
However, you can use the method below to do the authentication:
ApplicationUser signedUser = UserManager.FindByEmail(model.Email);
var result = await SignInManager.PasswordSignInAsync(signedUser.UserName, model.Password, model.RememberMe, shouldLockout: false);
switch (result)
{
case SignInStatus.Success:
return RedirectToLocal(returnUrl);
case SignInStatus.LockedOut:
return View("Lockout");
case SignInStatus.RequiresVerification:
return RedirectToAction("SendCode", new { ReturnUrl = returnUrl, RememberMe = model.RememberMe });
case SignInStatus.Failure:
default:
ModelState.AddModelError("", "Invalid login attempt.");
return PartialView(model);
}
