自定义ASP.NET Identity（二）- 修改ASP.NET Identity的用户主键

在Visual Studio 2013中,默认Web应用使用字符串作为用户账号的主键类型。ASP.NET Identity允许你根据你的数据需要改变这个主键的类型。泪如，你可以将主键类型有字符创类型修改为整数类型。

本章的主题将向你展示怎样开始默认的Web应用程序并且修改用户账户主键到整数类型。你可以使用相同的修改方法在你的工程中实现任意类型的用户账户主键。展示了在默认Web应用中怎样完成这些修改，你可以应用类似的修改方法定制应用。还将展示MVC或者Web Forms中所应该做的修改。

在本教程中学习的步骤，你必须使用Visual Studio 2013 Update2（或者更高版本），从ASP.NET Web 应用模板创建一个Web应用。Update3中的模板改变了，本主题将展示怎样在Update2和Update3中修改模板。

本章包含以下章节：

修改身份用户类主键类型 修改自定义身份类的主键类型 修改上下文类和用户管理器的主键类型 修改主键类型的启动配置 MVC with Update 2, 修改AccountController的主键类型 MVC with Update 3, 修改AccountController和ManageController的主键类型 Web Forms Update 2, 修改Account页面的主键类型 Web Forms Update 3, 修改Account页面的主键类型 运行应用

修改身份用户类主键类型

应用ASP.NET应用模板创建工程，指定ApplicationUser类的用户账号主键为整数类型。在IndentityModels.cs文件中，修改ApplicationUser类的继承接口IdentityUser的泛型参数TKey的类型为int类型。一也可以修改其它三个尚未实现的自定义类的名称。

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

你已经修改了主键类型，但是应用的其余部分这个主键仍然是字符串类型。你必须在代码中明确声明主键的类型。

在ApplicationUser类中，修改GenerateUserIdentityAsync方法使其包含int类型，如下高亮显示的代码。这个修改在Update 3的Web Forms工程中不是必要的。

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;
}

修改自定义身份类的主键类型

其它的Identity类，如：IdentityUserRole, IdentityUserClaim, IdentityUserLogin, IdentityRole, UserStore, RoleStore, 仍然使用字符串作为主键。使用整数类型作为主键创建这些类的新的版本。你不需要在这些类中实现太多的代码，你只需要设置int作为主键。

添加下面的类到你的IdentityModels.cs文件。

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)
{
}
}

修改上下文类和用户管理器的主键类型

在IdentityModels.cs文件中使用新的自定义类和int类型主键修改ApplicationDbContext类的定义。如下高亮代码所示：

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

ThrowIfV1Schema 参数在构造器中不在有效。修改构造器使其不再使用ThrowIfV1Schema 参数值。

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

打开IdentityConfig.cs文件，使用新的带有int类型主键的用户存储类修改ApplicationUserManger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 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;
}
}

在Update 3的模板中，你必须修改ApplicationSignInManager 类。

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

修改主键类型的启动配置

在Startup.Auth.cs文件中，替换OnValidateIndentity的代码，如下面高亮所示。注意getUserIdCallback的定义，解析字符串值到整整。

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>()))
}
});

如果你的工程不识别GetUserId方法的实现，你可能需要更新ASP.NET Identity的NuGet包到2.1版本。

你已经对ASP.NET Identity的基础类做了很多的修改。如果试着编译工程，你将被提示很多的错误。幸运的是，出现的错误都是相似的。Identity类期待一个整型主键值，但是控制器（或者Web Form）传递了一个字符串值。每一种情况下你都需要将字符串转换为整型来调用GetUserId<int>方法。你可以根据编译错误列表或者按照下面的进行修改来处理错误。

剩下的修改取决于工程类型，你正在创建和在Visual Studio中安装的更新版本。你可以通过下面的连接直接找到相关的处理方法。

}
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);
}

public async Task<ActionResult> LinkLoginCallback()
{
var loginInfo = await AuthenticationManager.GetExternalLoginInfoAsync(XsrfKey,
User.Identity.GetUserId());
if (loginInfo == null)
{
return RedirectToAction("Manage", new { Message = ManageMessageId.Error });
}
IdentityResult result = await UserManager.AddLoginAsync(

运行应用

你已经修改了默认Web应用模板所有需要修改的位置。运行应用并且注册一个新用户。注册之后，你将会注意到AspNetUsers表中有一个Id列是整型的。



如果你之前已经创建的ASP.NET Identity表使用了不同类型主键，你需要做一些附加的修改。如果可能，尽量删除已经存在的数据库。当你运行Web应用并且添加一个新用户是，数据库将被使用修正后的设计进行重建。如果无法删除，可以运行代码优先迁移修改这些表。然而，你的整型主键在数据库中将不会被设置为SQL IDENTITY属性。你必须手动设置Id列作为IDENTITY。
