ASP.. NET Identity: ApplicationUserRole的附加属性

Question

我为ApplicationUserRole添加了一个额外的属性，如下所示:

public class ApplicationUserRole : IdentityUserRole<int>
    {
        public string RoleAssigner { get; set; }
    }

现在我要给一个用户分配一个角色，如下所示:

[HttpPost]
    public ActionResult Create(UserRoleViewModel userRoleViewModel)
    {
        if (ModelState.IsValid)
        {
            using (var context = new ApplicationDbContext())
            {
                var userRole = new ApplicationUserRole
                {
                    UserId = userRoleViewModel.UserId,
                    RoleId = userRoleViewModel.RoleId,
                    RoleAssigner = userRoleViewModel.RoleAssigner
                };
                context.ApplicationUserRoles.Add(userRole);
                context.SaveChanges();
                return RedirectToAction("Index");
            }               
        }
        return View(userRoleViewModel);
    }

这个工作得很好!

在添加额外的"RoleAssigner"属性之前，我可以使用AddToRoles()方法为用户分配角色，如下所示:

[HttpPost]
    public ActionResult Create(UserRoleViewModel userRoleViewModel)
    {
        if (ModelState.IsValid)
        {      
             UserManager.AddToRoles(userRoleViewModel.Id,   userRoleViewModel.RoleName);
            return RedirectToAction("Index");
         }
        return View(userRoleViewModel);
    }

我的问题是:添加了一个额外的属性，如"RoleAssigner"，是否有任何方法来分配一个角色给用户使用AddToRoles()方法，这也将插入额外的"RoleAssigner"值"RoleAssigner"列在数据库中。

使用工作示例编辑:

我认为你可以通过在IdentityConfig创建一个扩展方法来做到这一点。我做了类似的事情，通过用户名或电话号码

查找用户

在我能够理解你想要调用UserManager.AddToRoles(…)和填写新的角色属性

要做到这一点(与前面的示例类似)，您需要扩展到user manager。你可以这样做:

public static class UserManagerExtens
{
    public static IdentityResult AddToRole(this ApplicationUserManager userManager,string userId,string[] roles,string assigner)
    {
        try
        {
            ApplicationUserRole role = null;
            using (ApplicationDbContext context = new ApplicationDbContext())
            {
                foreach (var item in roles)
                {
                    role = new ApplicationUserRole();
                    role.UserId = userId;
                    role.RoleAssigner = assigner;
                    role.RoleId = item;
                    context.AspNetUserRoles.Add(role);
                }
                context.SaveChanges();
            }
            return new IdentityResult() { };
        }
        catch (Exception ex)
        {
            return new IdentityResult(ex.Message);
        }
    }
}

这是一个工作的例子，使用UserManager你可以调用它定义参数:

string[] roles = new string[] { /*your roles here*/ };
UserManager.AddToRole(/*UserIdHere*/, roles, /*assigerId here*/);

与此类似，您可以实现async或UserManager的其他方法

如果你在startup.cs中使用asp.net core应用程序，你应该注入适当的存储模型

services.AddIdentity<ApplicationUser, YOURROLEMODEL(ApplicationUserRole )>()

如果你正在使用asp.net应用程序应该有IdentityConfig.cs文件你应该实现你的UserStore这将让你的角色模型作为通用。您可以看到我已经创建了AppUserStore类，并且它将MyIdentityRole模型作为泛型类型。并更改ApplicationUserManager使用我的AppUserStore类。

 public static ApplicationUserManager Create(IdentityFactoryOptions<ApplicationUserManager> options, IOwinContext context) 
    {
        var manager = new ApplicationUserManager(new AppUserStore(context.Get<ApplicationDbContext>()));
        // Configure validation logic for usernames
        manager.UserValidator = new UserValidator<ApplicationUser>(manager)
        {
            AllowOnlyAlphanumericUserNames = false,
            RequireUniqueEmail = true
        };
        // Configure validation logic for passwords
        manager.PasswordValidator = new PasswordValidator
        {
            RequiredLength = 6,
            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>
        {
            MessageFormat = "Your security code is {0}"
        });
        manager.RegisterTwoFactorProvider("Email Code", new EmailTokenProvider<ApplicationUser>
        {
            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>(dataProtectionProvider.Create("ASP.NET Identity"));
        }
        return manager;
    }
}
public class AppUserStore :
    UserStore<ApplicationUser, MyIdentityRole, string, IdentityUserLogin, IdentityUserRole, IdentityUserClaim>, IUserStore<ApplicationUser>
{
    public AppUserStore(DbContext context) : base(context)
    {
    }
}
public class MyIdentityRole : IdentityRole
{
    public string MyProperty { get; set; }
}
