Mengubah Kunci Primer untuk Pengguna di identitas ASP.NET

oleh Tom FitzMacken

Di Visual Studio 2013, aplikasi web default menggunakan nilai string untuk kunci untuk akun pengguna. ASP.NET Identity memungkinkan Anda mengubah jenis kunci untuk memenuhi persyaratan data Anda. Misalnya, Anda dapat mengubah jenis kunci dari string menjadi bilangan bulat.

Topik ini menunjukkan cara memulai dengan aplikasi web default dan mengubah kunci akun pengguna menjadi bilangan bulat. Anda dapat menggunakan modifikasi yang sama untuk mengimplementasikan semua jenis kunci dalam proyek Anda. Ini menunjukkan cara membuat perubahan ini di aplikasi web default, tetapi Anda dapat menerapkan modifikasi serupa ke aplikasi yang disesuaikan. Ini menunjukkan perubahan yang diperlukan saat bekerja dengan MVC atau Formulir Web.

Versi perangkat lunak yang digunakan dalam tutorial

  • Visual Studio 2013 dengan Pembaruan 2 (atau yang lebih baru)
  • ASP.NET Identity 2.1 atau yang lebih baru

Untuk melakukan langkah-langkah dalam tutorial ini, Anda harus memiliki Visual Studio 2013 Update 2 (atau yang lebih baru), dan aplikasi web yang dibuat dari templat Aplikasi Web ASP.NET. Templat berubah di Pembaruan 3. Topik ini memperlihatkan cara mengubah templat di Pembaruan 2 dan Pembaruan 3.

Topik ini berisi bagian berikut:

Mengubah jenis kunci di kelas pengguna Identitas

Dalam proyek Anda yang dibuat dari templat aplikasi web ASP.NET, tentukan bahwa kelas ApplicationUser menggunakan bilangan bulat untuk kunci untuk akun pengguna. Di IdentityModels.cs, ubah kelas ApplicationUser untuk mewarisi dari IdentityUser yang memiliki jenis int untuk parameter generik TKey. Anda juga meneruskan nama tiga kelas yang disesuaikan yang belum Anda terapkan.

public class ApplicationUser : IdentityUser<int, CustomUserLogin, CustomUserRole, 
    CustomUserClaim> 
{ 
    ...

Anda telah mengubah jenis kunci, tetapi, secara default, sisa aplikasi masih mengasumsikan kuncinya adalah string. Anda harus secara eksplisit menunjukkan jenis kunci dalam kode yang mengasumsikan string.

Di kelas ApplicationUser , ubah metode GenerateUserIdentityAsync untuk menyertakan int, seperti yang ditunjukkan pada kode yang disorot di bawah ini. Perubahan ini tidak diperlukan untuk proyek Formulir Web dengan templat Pembaruan 3.

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; 
}

Menambahkan kelas Identitas yang dikustomisasi yang menggunakan jenis kunci

Kelas Identitas lainnya, seperti IdentityUserRole, IdentityUserClaim, IdentityUserLogin, IdentityRole, UserStore, RoleStore, masih disiapkan untuk menggunakan kunci string. Buat versi baru kelas ini yang menentukan bilangan bulat untuk kunci. Anda tidak perlu memberikan banyak kode implementasi di kelas-kelas ini, Anda terutama hanya mengatur int sebagai kunci.

Tambahkan kelas berikut ke file IdentityModels.cs Anda.

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) 
    { 
    } 
}

Mengubah kelas konteks dan manajer pengguna untuk menggunakan jenis kunci

Di IdentityModels.cs, ubah definisi kelas ApplicationDbContext untuk menggunakan kelas baru yang disesuaikan dan int untuk kunci, seperti yang ditunjukkan dalam kode yang disorot.

public class ApplicationDbContext : IdentityDbContext<ApplicationUser, CustomRole, 
    int, CustomUserLogin, CustomUserRole, CustomUserClaim> 
{ 
    ...

Parameter ThrowIfV1Schema tidak lagi valid di konstruktor. Ubah konstruktor sehingga tidak melewati nilai ThrowIfV1Schema.

public ApplicationDbContext() 
    : base("DefaultConnection") 
{ 
}

Buka IdentityConfig.cs, dan ubah kelas ApplicationUserManger untuk menggunakan kelas penyimpanan pengguna baru Anda untuk menyimpan data dan int untuk kunci.

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 = 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, int> 
        { 
            MessageFormat = "Your security code is: {0}" 
        }); 
        manager.RegisterTwoFactorProvider("EmailCode", 
            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; 
    } 
}

Di templat Pembaruan 3, Anda harus mengubah kelas ApplicationSignInManager.

public class ApplicationSignInManager : SignInManager<ApplicationUser, int>
{ ... }

Mengubah konfigurasi start-up untuk menggunakan jenis kunci

Di Startup.Auth.cs, ganti kode OnValidateIdentity, seperti yang disorot di bawah ini. Perhatikan bahwa definisi getUserIdCallback, mengurai nilai string menjadi bilangan bulat.

app.UseCookieAuthentication(new CookieAuthenticationOptions 
    { 
        AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie, 
        LoginPath = new PathString("/Account/Login"), 
        Provider = new CookieAuthenticationProvider 
        { 
            OnValidateIdentity = SecurityStampValidator
                .OnValidateIdentity<ApplicationUserManager, ApplicationUser, int>( 
                    validateInterval: TimeSpan.FromMinutes(30), 
                    regenerateIdentityCallback: (manager, user) => 
                        user.GenerateUserIdentityAsync(manager), 
                    getUserIdCallback:(id)=>(id.GetUserId<int>()))
        } 
    });

Jika proyek Anda tidak mengenali implementasi generik metode GetUserId , Anda mungkin perlu memperbarui paket ASP.NET Identity NuGet ke versi 2.1

Anda telah membuat banyak perubahan pada kelas infrastruktur yang digunakan oleh ASP.NET Identity. Jika Anda mencoba mengkompilasi proyek, Anda akan melihat banyak kesalahan. Untungnya, kesalahan yang tersisa semuanya serupa. Kelas Identitas mengharapkan bilangan bulat untuk kunci, tetapi pengontrol (atau Formulir Web) meneruskan nilai string. Dalam setiap kasus, Anda perlu mengonversi dari string ke dan bilangan bulat dengan memanggil getUserId<int>. Anda dapat bekerja melalui daftar kesalahan dari kompilasi atau mengikuti perubahan di bawah ini.

Perubahan yang tersisa bergantung pada jenis proyek yang Anda buat dan pembaruan mana yang telah Anda instal di Visual Studio. Anda dapat langsung masuk ke bagian yang relevan melalui tautan berikut

Untuk MVC dengan Pembaruan 2, ubah AccountController untuk meneruskan jenis kunci

Buka file AccountController.cs. Anda perlu mengubah metode berikut.

public async Task<ActionResult> ConfirmEmail(int userId, string code) 
{ 
    if (userId == default(int) || code == null)  
    { 
        return View("Error"); 
    } 

    IdentityResult result = await UserManager.ConfirmEmailAsync(userId, code); 
    if (result.Succeeded) 
    { 
        return View("ConfirmEmail"); 
    } 
    else 
    { 
        AddErrors(result); 
        return View(); 
    } 
}

        User.Identity.GetUserId<int>(), 
        new UserLoginInfo(loginProvider, providerKey)); 
    if (result.Succeeded) 
    { 
        var user = await UserManager.FindByIdAsync(User.Identity.GetUserId<int>()); 
        await SignInAsync(user, isPersistent: false); 
        message = ManageMessageId.RemoveLoginSuccess; 
    }

                model.NewPassword); 
            if (result.Succeeded) 
            { 
                var user = await UserManager.FindByIdAsync(
                  User.Identity.GetUserId<int>()); 
                await SignInAsync(user, isPersistent: false); 
                return RedirectToAction("Manage", new { 
                    Message = ManageMessageId.ChangePasswordSuccess }); 
            } 
            else 
            { 
                AddErrors(result); 
            } 
        } 
    } 
    else 
    { 
        // User does not have a password so remove any validation errors caused 
        // by a missing OldPassword field 
        ModelState state = ModelState["OldPassword"]; 
        if (state != null) 
        { 
            state.Errors.Clear(); 
        } 

        if (ModelState.IsValid) 
        { 
            IdentityResult result = await UserManager.AddPasswordAsync(
                User.Identity.GetUserId<int>(), model.NewPassword); 
            if (result.Succeeded) 
            { 
                return RedirectToAction("Manage", new { 
                    Message = ManageMessageId.SetPasswordSuccess }); 
            } 
            else 
            { 
                AddErrors(result); 
            } 
        } 
    } 

    // If we got this far, something failed, redisplay form 
    return View(model); 
}

        User.Identity.GetUserId());
    if (loginInfo == null)
    {
        return RedirectToAction("Manage", new { Message = ManageMessageId.Error });
    }
    IdentityResult result = await UserManager.AddLoginAsync(
        User.Identity.GetUserId<int>(), loginInfo.Login);
    if (result.Succeeded)
    {
        return RedirectToAction("Manage");
    }
    return RedirectToAction("Manage", new { Message = ManageMessageId.Error });
}

Metode RemoveAccountList

public ActionResult RemoveAccountList()
{
    var linkedAccounts = UserManager.GetLogins(User.Identity.GetUserId<int>());
    ViewBag.ShowRemoveButton = HasPassword() || linkedAccounts.Count > 1;
    return (ActionResult)PartialView("_RemoveAccountPartial", linkedAccounts);
}

Metode HasPassword

Menjalankan aplikasi

Anda telah menyelesaikan semua perubahan yang diperlukan pada templat Aplikasi Web default. Jalankan aplikasi dan daftarkan pengguna baru. Setelah mendaftarkan pengguna, Anda akan melihat bahwa tabel AspNetUsers memiliki kolom Id yang merupakan bilangan bulat.

kunci primer baru

Jika sebelumnya Anda telah membuat tabel ASP.NET Identity dengan kunci primer yang berbeda, Anda perlu membuat beberapa perubahan tambahan. Jika memungkinkan, cukup hapus database yang ada. Database akan dibuat ulang dengan desain yang benar saat Anda menjalankan aplikasi web dan menambahkan pengguna baru. Jika penghapusan tidak dimungkinkan, jalankan migrasi pertama kode untuk mengubah tabel. Namun, kunci primer bilangan bulat baru tidak akan disiapkan sebagai properti IDENTITAS SQL dalam database. Anda harus mengatur kolom Id secara manual sebagai IDENTITY.
