Question

默认情况下，VS 2015中的ASP.NET身份使用字符串作为AspNet ***表的主键。我想改用int-typed id。经过一些研究后发现，开箱即用的框架支持不同类型的id。在下面的答案中，我将展示为实现这一目标所做的改变。

更新：在添加我的回答后，我在asp.net网站上发现了这篇博文，描述了相同但更全面的内容：http://www.asp.net/identity/overview/extensibility/change-primary-key-for-users-in-aspnet-identity

Answer 1

IdentityModels.cs更改为：

// New derived classes
public class UserRole : IdentityUserRole<int>
{
}

public class UserClaim : IdentityUserClaim<int>
{
}

public class UserLogin : IdentityUserLogin<int>
{
}

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

public class UserStore : UserStore<ApplicationUser, Role, int,
    UserLogin, UserRole, UserClaim>
{
    public UserStore(ApplicationDbContext context): base(context)
    {
    }
}

public class RoleStore : RoleStore<Role, int, UserRole>
{
    public RoleStore(ApplicationDbContext context): base(context)
    {
    }
}

// You can add profile data for the user by adding more properties to your ApplicationUser class, please visit http://go.microsoft.com/fwlink/?LinkID=317594 to learn more.
public class ApplicationUser : IdentityUser<int, UserLogin, UserRole, UserClaim>
{
    public DateTime? ActiveUntil;

    public async Task<ClaimsIdentity> GenerateUserIdentityAsync(ApplicationUserManager 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 ApplicationDbContext : IdentityDbContext<ApplicationUser, Role, int,
    UserLogin, UserRole, UserClaim>
{
    public ApplicationDbContext()
        : base("DefaultConnection")
    {
    }

    public static ApplicationDbContext Create()
    {
        return new ApplicationDbContext();
    }
}

在`App_Start \ IdentityConfig.cs中，更改以下类：

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 UserStore(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 = 8,
            // 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);
    }
}

在App_Start\Startup.Auth.cs将OnValidateIdentity属性更改为：

OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<ApplicationUserManager, ApplicationUser, int>(
    validateInterval: TimeSpan.FromMinutes(30),
    regenerateIdentityCallback: (manager, user) => user.GenerateUserIdentityAsync(manager),
    getUserIdCallback: id => id.GetUserId<int>())

更改ManageController以使用新的pk类型：

将User.Identity.GetUserId()的所有条目替换为User.Identity.GetUserId<int>()

可能会有一些字符串id参数需要更改为int，但这就是它。

Answer 2

使用ASP.NET核心标识的每this blog post进行以下更改：

首先，转到Data\Migrations文件夹并删除其中的所有内容。

在Startup.cs中，在ConfigureServices方法中，将services.AddIdentity更改为

services.AddIdentity<ApplicationUser, IdentityRole<int>>()
   .AddEntityFrameworkStores<ApplicationDbContext, int>()
   .AddDefaultTokenProviders();

在ApplicationDbContext.cs中将基类从IdentityDbContext<ApplicationUser>更改为

public class ApplicationDbContext
  : IdentityDbContext<ApplicationUser, IdentityRole<int>, int>

最后，将ApplicationUser.cs中的基类从IdentityUser更改为

public class ApplicationUser : IdentityUser<int>

然后运行add-migration -o Data\Migrations和update-database。如果迁移导致任何问题，请使用VS中的Sql Server Management Studio或SqlServerObjectExplorer删除数据库（不仅使用文件系统），重新删除迁移，然后重试。 / p>
