SignInManager бросает нуль при попытке войти в систему

Question

Я реализую идентификацию asp.net. Я переопределил классы по умолчанию с помощью первичного ключа int, а не по умолчанию String. Я выполнил следующую статью, чтобы сделать это: Article

Извините за весь код, однако я был застрял на этой глупой ошибке в течение некоторого времени, поэтому я скорее дал больше информации, чем меньше.

У меня есть следующие классы:

public class FskUser : IdentityUser<int, FskUserLogin, FskUserRole, FskUserClaim> 
{ 
    ... 
    public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<FskUser, int> manager) 
    { 
        // Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType 
     var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie); 
     // Add custom user claims here 
     return userIdentity; 
    } 
} 

Мой заказ SignInManager

public class FskSignInManager : SignInManager<FskUser,int> 
{ 
    public FskSignInManager(FskUserManager userManager, IAuthenticationManager authenticationManager) 
     : base(userManager, authenticationManager) 
    { 
    } 

    public override Task<ClaimsIdentity> CreateUserIdentityAsync(FskUser user) 
    { 
     return user.GenerateUserIdentityAsync((FskUserManager)UserManager); 
    } 

    public static FskSignInManager Create(IdentityFactoryOptions<FskSignInManager> options, IOwinContext context) 
    { 
     return new FskSignInManager(context.GetUserManager<FskUserManager>(), context.Authentication); 
    } 
} 

Мои StartUp.Auth.cs

public void ConfigureAuth(IAppBuilder app) 
    { 
     // Configure the db context, user manager and signin manager to use a single instance per request 
     app.CreatePerOwinContext(IdentityDbContext.Create); 
     app.CreatePerOwinContext<FskUserManager>(FskUserManager.Create); 
     app.CreatePerOwinContext<FskSignInManager>(FskSignInManager.Create); 

     // Enable the application to use a cookie to store information for the signed in user 
     // and to use a cookie to temporarily store information about a user logging in with a third party login provider 
     // Configure the sign in cookie 
     app.UseCookieAuthentication(new CookieAuthenticationOptions 
     { 
      AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie, 
      LoginPath = new PathString("/Account/Login"), 
      Provider = new CookieAuthenticationProvider 
      { 
       // Enables the application to validate the security stamp when the user logs in. 
       // This is a security feature which is used when you change a password or add an external login to your account. 
       OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<FskUserManager, FskUser, int>(
      validateInterval: TimeSpan.FromMinutes(30), 
      regenerateIdentityCallback: (manager, user) => 
       user.GenerateUserIdentityAsync(manager), 
      getUserIdCallback: (id) => (id.GetUserId<int>()))     
      } 
     });   app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);  
      } 

Вот мой аккаунт контроллер упрощена:

[Authorize] 
public class AccountController : Controller 
{ 
    private FskSignInManager _signInManager; 
    private FskUserManager _userManager; 

    public AccountController() 
    { 
    } 

    public AccountController(FskUserManager userManager, FskSignInManager signInManager) 
    { 
     UserManager = userManager; 
     SignInManager = signInManager; 
    } 

    public FskSignInManager SignInManager 
    { 
     get 
     { 
      if (_signInManager == null) 
      { 
       //split for debug purposes 
       var cntx = HttpContext.GetOwinContext(); 
       var tmp = cntx.Get<FskSignInManager>(); 
       return tmp; 
      } 
      else 
      { 
       return _signInManager; 
      } 
     } 
     private set 
     { 
      _signInManager = value; 
     } 
    } 

    public FskUserManager UserManager 
    { 
     get 
     { 
      return _userManager ?? HttpContext.GetOwinContext().GetUserManager<FskUserManager>(); 
     } 
     private set 
     { 
      _userManager = value; 
     } 
    } 

    // 
    // POST: /Account/Login 
    [HttpPost] 
    [AllowAnonymous] 
    [ValidateAntiForgeryToken] 
    public async Task<ActionResult> Login(LoginViewModel model, string returnUrl) 
    { 
     if (!ModelState.IsValid) 
     { 
      return View(model); 
     } 
     *** line below causes the error ***    
     var result = await SignInManager.PasswordSignInAsync(model.Email, 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 View(model); 
     } 
    } 
} 

И это сообщение об ошибке, которое я получаю, когда я пытаюсь Войти:

Answer 1

Для меня это был результат нулевой ClaimValue

user.Claims.Add(new IdentityUserClaim<string> 
      { 
       ClaimType = item.Key, 
       ClaimValue = item.Value 
      }); 

Я решил его, изменив код

user.Claims.Add(new IdentityUserClaim<string> 
      { 
       ClaimType = item.Key, 
       ClaimValue = item.Value != null ? item.Value : "" 
      });
