CreateIdentityAsync，RavenDb.AspNet.Identity。例外情況：UserId找不到

Question

我已經看到了這個主題中的其他問題，但似乎我錯過了某些我從其他問題找不到的東西。也許它與RavenDb.AspNet.Identity有關。無論如何，我無法看到我的代碼在哪裏做錯了。

當我註冊一個用戶。一切順利，保存到RavenDb IdentityUserByUserName和ApplicationUser。但是當它登錄到await SignInManager.SignInAsync(user, isPersistent: false, rememberBrowser: false); 時出現問題。並引發錯誤：「找不到UserId」。

public class ApplicationUser : IdentityUser 
    { 
     public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> 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; 
     } 
    } 

     //from AccountController start 
     [AllowAnonymous] 
    [ValidateAntiForgeryToken] 
    public async Task<ActionResult> Register(RegisterViewModel model) 
    { 
     if (ModelState.IsValid) 
     { 
      var user = new ApplicationUser { UserName = model.Email, Email = model.Email, Id = "RavenDbUsers/" + model.Email }; 

      var result = await UserManager.CreateAsync(user, model.Password); 
      await AsyncDataSession.SaveChangesAsync(); 

      if (result.Succeeded) 
      { 
       await SignInManager.SignInAsync(user, isPersistent: false, rememberBrowser: false); 

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

     // If we got this far, something failed, redisplay form 
     return View(model); 
    } 
    //from AccountController end 


    public class ApplicationSignInManager : SignInManager<ApplicationUser, string> 
    { 
     public ApplicationSignInManager(ApplicationUserManager userManager, IAuthenticationManager authenticationManager) 
      : base(userManager, authenticationManager) 
     { 
     } 

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

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

UPDATE：

//構造函數，SingInManager，控制器的UserManager

 private ApplicationSignInManager _signInManager; 
    private UserManager<ApplicationUser> _userManager; 

    public AccountController() 
    { 
     _userManager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(() => AsyncDataSession)); 
    } 

    public ApplicationSignInManager SignInManager 
    { 
     get 
     { 
      return _signInManager ?? HttpContext.GetOwinContext().Get<ApplicationSignInManager>(); 
     } 
     private set 
     { 
      _signInManager = value; 
     } 
    } 

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

//更新時間：ApplicationUserManager

public class ApplicationUserManager : UserManager<ApplicationUser> 
    { 
    public ApplicationUserManager(IUserStore<ApplicationUser> store) 
      : base(store) 
    { 
    } 

    public static ApplicationUserManager Create(IdentityFactoryOptions<ApplicationUserManager> options, IOwinContext context) 
    { 
     var session = context.Get<IAsyncDocumentSession>(); 
     session.Advanced.UseOptimisticConcurrency = true; 

     var manager = new ApplicationUserManager(new UserStore<ApplicationUser>(session)); 
     manager.UserValidator = new UserValidator<ApplicationUser>(manager) 
     { 
      AllowOnlyAlphanumericUserNames = false, 
      RequireUniqueEmail = true 
     }; 

     manager.PasswordValidator = new PasswordValidator 
     { 
      RequiredLength = 6, 
      RequireNonLetterOrDigit = true, 
      RequireDigit = true, 
      RequireLowercase = true, 
      RequireUppercase = true, 
     }; 

     manager.UserLockoutEnabledByDefault = true; 
     manager.DefaultAccountLockoutTimeSpan = TimeSpan.FromMinutes(5); 
     manager.MaxFailedAccessAttemptsBeforeLockout = 5; 

     manager.RegisterTwoFactorProvider("Phone Code", new PhoneNumberTokenProvider<ApplicationUser> 
     { 
      MessageFormat = "Your security code is {0}" 
     }); 
     manager.RegisterTwoFactorProvider("Email Code", new EmailTokenProvider<ApplicationUser> 
     { 
      Subject = "Security Code", 
      BodyFormat = "Your security code is {0}" 
     }); 
     manager.EmailService = new EmailService(); 
     manager.SmsService = new SmsService(); 
     var dataProtectionProvider = options.DataProtectionProvider; 
     if (dataProtectionProvider != null) 
     { 
      manager.UserTokenProvider = 
        new DataProtectorTokenProvider<ApplicationUser>(dataProtectionProvider.Create("ASP.NET Identity")); 
     } 
     return manager; 
    }

RavenDB.AspNet.Identity的作者在這裏。

當你到這一行時，user.Id的值是什麼？

await SignInManager.SignInAsync(user, isPersistent: false, rememberBrowser: false); 

此外，您可以驗證用戶實際存在數據庫之前，該代碼執行？

我的心理調試技巧告訴我你的UserManager可能使用與accountController.AsyncDataSession不同的IAsyncDocumentSession，因此，當你進行SignInAsync調用時，用戶實際上並不在數據庫中。
