在VS2015中的ASP.NET标识中将用户标识类型更改为int

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更改.

更新:在添加我的答案后,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-在-ASPNET身份

IdentityModels.cs 改为:

// New derived classes
public class UserRole : IdentityUserRole
{
}

public class UserClaim : IdentityUserClaim
{
}

public class UserLogin : IdentityUserLogin
{
}

public class Role : IdentityRole
{
    public Role() { }
    public Role(string name) { Name = name; }
}

public class UserStore : UserStore
{
    public UserStore(ApplicationDbContext context): base(context)
    {
    }
}

public class RoleStore : RoleStore
{
    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
{
    public DateTime? ActiveUntil;

    public async Task 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
{
    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
{
    public ApplicationUserManager(IUserStore store)
        : base(store)
    {
    }

    public static ApplicationUserManager Create(IdentityFactoryOptions options, IOwinContext context) 
    {
        var manager = new ApplicationUserManager(new UserStore(context.Get()));
        // Configure validation logic for usernames
        manager.UserValidator = new UserValidator(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
        {
            MessageFormat = "Your security code is {0}"
        });
        manager.RegisterTwoFactorProvider("Email Code", new EmailTokenProvider
        {
            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(dataProtectionProvider.Create("ASP.NET Identity"));
        }
        return manager;
    }
}

// Configure the application sign-in manager which is used in this application.
public class ApplicationSignInManager : SignInManager
{
    public ApplicationSignInManager(ApplicationUserManager userManager, IAuthenticationManager authenticationManager)
        : base(userManager, authenticationManager)
    {
    }

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

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

在App_Start\Startup.Auth.cs更改OnValidateIdentity属性中:

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

更改ManageController以使用新的pk类型:

替换的所有条目User.Identity.GetUserId()来User.Identity.GetUserId()

可能有一些id需要更改的字符串参数int,但这就是它.

如果您可以准确地突出显示代码中创建int id的内容，那将是非常好的。

根据此博客文章,使用ASP.NET Core Identity,进行以下更改:

首先,转到该Data\Migrations文件夹并删除其中的所有内容.

在Startup.cs,ConfigureServices方法中,services.AddIdentity改为

services.AddIdentity>()
   .AddEntityFrameworkStores()
   .AddDefaultTokenProviders();

在ApplicationDbContext.cs改变从基类IdentityDbContext到

public class ApplicationDbContext
  : IdentityDbContext, int>

最后,在更改基类ApplicationUser.cs从IdentityUser到

public class ApplicationUser : IdentityUser

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(不要只使用文件系统),重新删除迁移,然后重试.

对于.NET Core 2. *及更高版本，将`.AddEntityFrameworkstores <ApplicationDbContext，int>（）`更改为`.AddEntityFrameworkStores <ApplicationDbContext>（）`即可。
