asp.net-mvc-5 - 在GenerateUserIdentityAsync方法的aspnet Identity中找不到UserId错误

Question

在注册用户和登录后，我收到 UserId not found 错误。此外，注册后，数据将保存到数据库和 dbo.AspNetUsers 表中，id 列自动递增，返回类型为 int。AspNetUserClaims 表中有 UserId 列。它有 4 Col---Id、UserId、ClaimType、ClaimValue。它的 Id 列自动递增，而不是 userId。我最初通过以下链接成功地将主键从 string 更改为 int --- http://www.asp.net/identity/overview/extensibility/change-primary-key-for-users-in-aspnet-identity .

它之前运行成功，但现在它在这一行给我错误---

  public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser, 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;
    }

异常详细信息:System.InvalidOperationException:找不到 UserId。这是完整的堆栈跟踪。你可以在这里看到----http://pastebin.com/0hp5eAnp

它之前工作正常，但现在当我添加与其他表的外键关系时，我不知道那里缺少什么。在数据库中，所有表都已正确创建，它们之间的关系也正确，但这里缺少一些东西。

我的ApplicationUser类是这样的-----

 public class ApplicationUser : IdentityUser<int, CustomUserLogin, CustomUserRole, CustomUserClaim>
 {
    public ApplicationUser()
    {
        this.Posts = new HashSet<Post>();
    }
    [Key]
    [DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)]
    public int Id { get; set; }
    public virtual ICollection<Post> Posts { get; set; }
    public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser, 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;
    }
    public class CustomUserRole : IdentityUserRole<int> { }
    public class CustomUserClaim : IdentityUserClaim<int> { }
    public class CustomUserLogin : IdentityUserLogin<int> { }

    public class CustomRole : IdentityRole<int, CustomUserRole>
   {
    public CustomRole() { }
    public CustomRole(string name) { Name = name; }
}

public class CustomUserStore : UserStore<ApplicationUser, CustomRole, int,
    CustomUserLogin, CustomUserRole, CustomUserClaim>
{
    public CustomUserStore(ApplicationDbContext context)
        : base(context)
    {
    }
}

public class CustomRoleStore : RoleStore<CustomRole, int, CustomUserRole>
{
    public CustomRoleStore(ApplicationDbContext context)
        : base(context)
    {
    }
} 

我的 IdentityConfig.cs 类文件是这样的 ------

     // Configure the application user manager used in this application. UserManager is defined in ASP.NET Identity and is used by the application.
public class ApplicationUserManager : UserManager<ApplicationUser, int>
{
    public ApplicationUserManager(IUserStore<ApplicationUser, int> store)
        : base(store)
    {
    }

    public static ApplicationUserManager Create(IdentityFactoryOptions<ApplicationUserManager> options, IOwinContext context) 
    {
        var manager = new ApplicationUserManager(new CustomUserStore(context.Get<ApplicationDbContext>()));
        // Configure validation logic for usernames
        manager.UserValidator = new UserValidator<ApplicationUser, int>(manager)
        {
            AllowOnlyAlphanumericUserNames = false,
            RequireUniqueEmail = true
        };

        // Configure validation logic for passwords
        manager.PasswordValidator = new PasswordValidator
        {
            RequiredLength = 1,
            //RequireNonLetterOrDigit = true,
            //RequireDigit = true,
            //RequireLowercase = true,
            //RequireUppercase = true,
        };

        // Configure user lockout defaults
        manager.UserLockoutEnabledByDefault = true;
        manager.DefaultAccountLockoutTimeSpan = TimeSpan.FromMinutes(5);
        manager.MaxFailedAccessAttemptsBeforeLockout = 5;

        // Register two factor authentication providers. This application uses Phone and Emails as a step of receiving a code for verifying the user
        // You can write your own provider and plug it in here.
        manager.RegisterTwoFactorProvider("Phone Code", new PhoneNumberTokenProvider<ApplicationUser, int>
        {
            MessageFormat = "Your security code is {0}"
        });
        manager.RegisterTwoFactorProvider("Email Code", new EmailTokenProvider<ApplicationUser, int>
        {
            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, int>(dataProtectionProvider.Create("ASP.NET Identity"));
        }
        return manager;
    }
}

// Configure the application sign-in manager which is used in this application.
public class ApplicationSignInManager : SignInManager<ApplicationUser, int>
{
    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);
    }
}

我已经看过很多 stackoverflow 答案，但没有让它发挥作用。有人可以看看缺少什么吗，我现在应该做什么。提前致谢。在这里，在 applicationUser 类的 Id 列中，它在工具提示中显示一些警告和消息，如下所示 ----- models.ApplicationUSer.ID 隐藏继承成员 Microsoft.Aspnet.Identity.EntityFramework.IDentity 用户身份。使当前成员覆盖该实现，否则添加 override 关键字添加新关键字，其中 x 只是命名空间。

我的App_Start文件夹中的StartUp.Auth.cs是这样的-----

     public partial class Startup
    {
     public void ConfigureAuth(IAppBuilder app)
     {
        // Configure the db context, user manager and signin manager to use a single instance per request
        app.CreatePerOwinContext(ApplicationDbContext.Create);
        app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
        app.CreatePerOwinContext<ApplicationSignInManager>(ApplicationSignInManager.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<ApplicationUserManager, ApplicationUser, int>(
                    validateInterval: TimeSpan.FromMinutes(30),
                    regenerateIdentityCallback: (manager, user) => user.GenerateUserIdentityAsync(manager), getUserIdCallback:(id)=>(id.GetUserId<int>()))
            }
        });            
        app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);

        // Enables the application to temporarily store user information when they are verifying the second factor in the two-factor authentication process.
        app.UseTwoFactorSignInCookie(DefaultAuthenticationTypes.TwoFactorCookie, TimeSpan.FromMinutes(5));

        // Enables the application to remember the second login verification factor such as phone or email.
        // Once you check this option, your second step of verification during the login process will be remembered on the device where you logged in from.
        // This is similar to the RememberMe option when you log in.
        app.UseTwoFactorRememberBrowserCookie(DefaultAuthenticationTypes.TwoFactorRememberBrowserCookie);

        // Uncomment the following lines to enable logging in with third party login providers
        //app.UseMicrosoftAccountAuthentication(
        //    clientId: "",
        //    clientSecret: "");......................................................................

我的startUp.cs文件是这样的----

   [assembly: OwinStartupAttribute(typeof(WebApp.Startup))]
   namespace WebApp
   {
    public partial class Startup
   {
    public void Configuration(IAppBuilder app)
    {
        ConfigureAuth(app);
    }
   }
  }

您将必须拿出您的 ApplicationUserManager 使其美观、干净并实现更多方法...例如，请参阅以下帖子(它使用您的自定义键(示例中的 TKey)实现了所有方法:

http://www.symbolsource.org/MyGet/Metadata/aspnetwebstacknightly/Project/Microsoft.AspNet.Identity.Core/2.0.0-beta1-140211/Release/Default/Microsoft.AspNet.Identity.Core/Microsoft.AspNet.Identity.Core/UserManager.cs?ImageName=Microsoft.AspNet.Identity.Core

您将看到您收到的错误 GetSecurityStampAsync 也已在那里实现。
