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

Question

我已经看到了这个主题中的其他问题，但似乎我错过了某些我从其他问题找不到的东西。也许它与RavenDb.AspNet.Identity有关。无论如何，我无法看到我的代码在哪里做错了。

当我注册一个用户。一切顺利，保存到RavenDb IdentityUserByUserName和ApplicationUser。但是当它登录到await SignInManager.SignInAsync(user, isPersistent: false, rememberBrowser: false); 时出现问题。并引发错误：“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：

//构造函数，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; 
     } 
    } 

//更新时间：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的作者在这里。

当你到这一行时，user.Id的值是什么？

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

此外，您可以验证用户实际存在数据库之前，该代码执行？

我的心理调试技巧告诉我你的UserManager可能使用与accountController.AsyncDataSession不同的IAsyncDocumentSession，因此，当你进行SignInAsync调用时，用户实际上并不在数据库中。
