Question

我正在使用ASP.Net Identity 2和EF6代码首次迁移此项目，我正在努力创建一个表来链接其他3个表。我有以下内容：

公司
ApplicationUser（AspNetUsers）
ApplicationRole（AspNetRoles）
AspNetUserRoles

棘手的一点是将AspNetUserRoles与Company表相关联，因为用户可以在不同的公司中拥有角色，并且还可以拥有与任何公司无关的角色。理想情况下，我需要的结果表是：

CompanyUserRoles（companyId，UserRoleId [this is not roleID]）或甚至（companyId，roleid，userid）

另一个选择是将另一个字段（companyId）添加到AspNetUserRoles表。

如何通过代码优先实现这一点以及它对UserManager和RoleManager有什么影响（我是否需要创建自定义代码？），这有点令人困惑。

非常感谢任何指导。

根据相同的源代码编写代码自己现在走的假设。首先，使用mvc（c＃）在vs中创建新项目，并在mvc上选择项目类型。然后，在创建项目之后，您应该更改一些类Identity。我希望更改在表UserId中输入Nvarchar(128)到Bigint的{{1}}。第一步到第七步在AspNetUsers。

第一步：根据以下内容将类IdentityModels.cs更改为：

IdentityModels.cs

更改为：ApplicationUser : IdentityUser。

第二步：创建类：

ApplicationUser : IdentityUser<long, CustomUserLogin, CustomUserRole, CustomUserClaim>

第三步：根据：

更改课程

public class CustomUserRole : IdentityUserRole<long> { }
public class CustomUserClaim : IdentityUserClaim<long> { }
public class CustomUserLogin : IdentityUserLogin<long> { }

第四步：根据以下内容更改课程：

public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser, long> manager)

第五步：根据以下内容改变课程：

 public class CustomRole : IdentityRole<long, CustomUserRole>

第六步：根据以下内容改变课程：

 public class CustomUserStore : UserStore<ApplicationUser, CustomRole, long, CustomUserLogin, CustomUserRole, CustomUserClaim>

第七步：根据以下内容改变课程：

public class CustomRoleStore : RoleStore<CustomRole, long, CustomUserRole>

并根据您的表格字段将以下方法添加到public class ApplicationDbContext : IdentityDbContext<ApplicationUser, CustomRole, long, CustomUserLogin, CustomUserRole, CustomUserClaim>：

IdentityModels.cs

在protected override void OnModelCreating(DbModelBuilder modelBuilder) { base.OnModelCreating(modelBuilder); //modelBuilder.Entity<CustomUserLogin>() //.HasKey(r => new { r.UserId }) //.ToTable("tblRoles"); //modelBuilder.Entity<CustomUserLogin>() // .HasKey(l => new { l.LoginProvider, l.ProviderKey, l.UserId }) // .ToTable("tblMembers"); modelBuilder.Entity<IdentityUser>().HasKey(r => new { r.Id }).ToTable("tblMembers1").Property(p => p.Id).HasColumnName("UserID"); modelBuilder.Entity<ApplicationUser>().HasKey(r => new { r.Id }).ToTable("tblMembers").Property(p => p.Id).HasColumnName("UserID"); modelBuilder.Entity<IdentityUserRole>().HasKey(r => new { r.RoleId }).ToTable("tblRoless"); modelBuilder.Entity<IdentityUserLogin>().HasKey(r => new { r.UserId }).ToTable("tblLogins"); modelBuilder.Entity<IdentityUserClaim>().HasKey(r => new { r.Id }).ToTable("tblUserClaims"); modelBuilder.Entity<IdentityRole>().HasKey(r => new { r.Id }).ToTable("tblRoloess"); }根据以下内容进行更改

AccountControllers.cs

private bool HasPassword() { var user = UserManager.FindById(User.Identity.GetUserId<long>()); if (user != null) { return user.PasswordHash != null; } return false; } public virtual ActionResult RemoveAccountList() { var linkedAccounts = UserManager.GetLogins(User.Identity.GetUserId<long>()); ViewBag.ShowRemoveButton = HasPassword() || linkedAccounts.Count > 1; return PartialView("_RemoveAccountPartial", linkedAccounts); } public virtual async Task<ActionResult> Disassociate(string loginProvider, string providerKey) { ManageMessageId ? message = null; IdentityResult result = await UserManager.RemoveLoginAsync( User.Identity.GetUserId<long>(), new UserLoginInfo(loginProvider, providerKey)); if (result.Succeeded) { var user = await UserManager.FindByIdAsync(User.Identity.GetUserId<long>()); await SignInAsync(user, isPersistent: false); message = ManageMessageId.RemoveLoginSuccess; } else { message = ManageMessageId.Error; } return RedirectToAction("Manage", new { Message = message }); } private async Task SignInAsync(ApplicationUser user, bool isPersistent) { AuthenticationManager.SignOut(DefaultAuthenticationTypes.ExternalCookie); AuthenticationManager.SignIn(new AuthenticationProperties() { IsPersistent = isPersistent }, await user.GenerateUserIdentityAsync(UserManager)); }根据以下内容发生变化：

IdentityConfig.cs

然后，在工具菜单的Windows 程序包管理器控制台中编写以下命令以添加迁移：

  public class EmailService : IIdentityMessageService
{
    public Task SendAsync(IdentityMessage message)
    {
        // Plug in your email service here to send an email.
        return Task.FromResult(0);
    }
}

public class SmsService : IIdentityMessageService
{
    public Task SendAsync(IdentityMessage message)
    {
        // Plug in your SMS service here to send a text message.
        return Task.FromResult(0);
    }
}

// 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, long>
{
    public ApplicationUserManager(IUserStore<ApplicationUser, long> 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, long>(manager)
        {
            AllowOnlyAlphanumericUserNames = false,
            RequireUniqueEmail = true
        };
        // Configure validation logic for passwords 
        manager.PasswordValidator = new PasswordValidator
        {
            RequiredLength = 6,
            RequireNonLetterOrDigit = true,
            RequireDigit = true,
            RequireLowercase = true,
            RequireUppercase = true,
        };
        // 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 in here. 
        manager.RegisterTwoFactorProvider("PhoneCode",
            new PhoneNumberTokenProvider<ApplicationUser, long>
            {
                MessageFormat = "Your security code is: {0}"
            });
        manager.RegisterTwoFactorProvider("EmailCode",
            new EmailTokenProvider<ApplicationUser, long>
            {
                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, long>(
                    dataProtectionProvider.Create("ASP.NET Identity"));
        }
        return manager;
    }

    // Configure the application sign-in manager which is used in this application.
}

public class ApplicationSignInManager : SignInManager<ApplicationUser, long>
{
    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);
    }
}

然后：

最好的问候。

如何首先使用EF6代码在AspNetUserRoles和其他表之间创建关系？
