AspNet.Identity自定义用户和自定义角色应该很简单; 我错过了什么？

Question

使用http://www.asp.net/identity中的示例我已经走到了这一步.这些RoleManager作品完美无瑕,我对待它UserManager也是如此.我认为一切都是正确的,但我似乎无法UserManager在控制器中正确地创新.怎么了？有一次,我成功地UserManager开始工作,但是EntityValidationError在创建一个新用户时发出了一个说法"Id is required",UserManager.Create(user, password);在这个问题中发布了UserManager.Create(用户,密码)thowing EntityValidationError说Id是必需的？

所以经过一段时间的点击和未命中,我已经创建了如下所示的所有内容但是在编写时错误new ApplicationUserManager(new ApplicationUserStore(new MyAppDb()))说"最好的重载方法匹配'MyApp.Models.ApplicationUserManager.ApplicationUserManager(Microsoft.AspNet.Identity. IUserStore)'尝试在我的控制器中创建'UserManager'时'有一些无效的参数':

这是控制器:

namespace MyApp.Controllers
{
    [Authorize]
    public class AccountController : BaseController
    {
        public AccountController()
            : this(new ApplicationUserManager(new ApplicationUserStore(new MyAppDb())))
        {
        }

        public AccountController(ApplicationUserManager userManager)
        {
            UserManager = userManager;
        }

        public ApplicationUserManager UserManager { get; private set; }
...
}

这是模型:

namespace MyApp.Models
{
    public class ApplicationUser : IdentityUser<string, ApplicationUserLogin, ApplicationUserRole, ApplicationUserClaim>
    {
        [Required]
        [StringLength(50)]
        public string FirstName { get; set; }

        [Required]
        [StringLength(50)]
        public string LastName { get; set; }


        public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> 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 ApplicationUserLogin : IdentityUserLogin<string>
    {
    }

    public class ApplicationUserClaim : IdentityUserClaim<string>
    {
    }

    public class ApplicationUserRole : IdentityUserRole<string>
    {
    }

    public class ApplicationRole : IdentityRole<string, ApplicationUserRole>
    {
        [Required]
        [StringLength(50)]
        public string ProperName { get; set; }

        [Required]
        public string Description { get; set; }
    }


    public class MyAppDb : IdentityDbContext<ApplicationUser, ApplicationRole, string, ApplicationUserLogin, ApplicationUserRole, ApplicationUserClaim>
    {
        public MyAppDb()
            : base("MyAppDb")
        {
        }
    }


    public class ApplicationUserManager : UserManager<ApplicationUser>
    {
        public ApplicationUserManager(IUserStore<ApplicationUser> store)
            : base(store)
        {
            this.PasswordValidator = (IIdentityValidator<string>)new MinimumLengthValidator(8);
            this.UserValidator = new UserValidator<ApplicationUser>(this) { AllowOnlyAlphanumericUserNames = false, RequireUniqueEmail = true };
        }

    }

    public class ApplicationUserStore : UserStore<ApplicationUser, ApplicationRole, string, ApplicationUserLogin, ApplicationUserRole, ApplicationUserClaim>
    {
        public ApplicationUserStore(MyAppDb context)
            : base(context)
        {
        }

        public override async Task CreateAsync(ApplicationUser user)
        {
            await base.CreateAsync(user);

        }
    }


    public class ApplicationRoleStore : RoleStore<ApplicationRole, string, ApplicationUserRole>
    {
        public ApplicationRoleStore(MyAppDb context)
            : base(context)
        {
        }
    }

    public class ApplicationRoleManager : RoleManager<ApplicationRole>
    {
        public ApplicationRoleManager(IRoleStore<ApplicationRole, string> store)
            : base(store)
        {
        }

    }
}

更新:UserManager通过更改此设置,我可以通过创建来消除错误:

public class ApplicationUserManager : UserManager<ApplicationUser>
{
    public ApplicationUserManager(IUserStore<ApplicationUser> store)
        : base(store)
    {
        this.PasswordValidator = (IIdentityValidator<string>)new MinimumLengthValidator(8);
        this.UserValidator = new UserValidator<ApplicationUser>(this) { AllowOnlyAlphanumericUserNames = false, RequireUniqueEmail = true };
    }
}

对此:

public class ApplicationUserManager : UserManager<ApplicationUser>
{
    public ApplicationUserManager(IUserStore<ApplicationUser, string> store)
        : base(store)
    {
        this.PasswordValidator = (IIdentityValidator<string>)new MinimumLengthValidator(8);
        this.UserValidator = new UserValidator<ApplicationUser>(this) { AllowOnlyAlphanumericUserNames = false, RequireUniqueEmail = true };
    }
}

注意我刚刚添加, string,但它然后将错误"最佳重载方法匹配"Microsoft.AspNet.Identity.UserMaager.UserManager(Microsoft.AspNet.Identity.IUserStore)'有一些无效的参数"on base(store).

更新2:我改变了这个:

public class ApplicationUserManager : UserManager<ApplicationUser>
    {
        public ApplicationUserManager(IUserStore<ApplicationUser, string> store)
        ...
    }

对此:

public class ApplicationUserManager : UserManager<ApplicationUser, string>
    {
        public ApplicationUserManager(IUserStore<ApplicationUser, string> store)
        ...
    }

注意' string在public class ApplicationUserManager : UserManager<ApplicationUser, string>.但现在,猜猜怎么着？你猜对了 - 回到这个问题:UserManager.Create(用户,密码)thowing EntityValidationError说Id是必需的？

我错过了什么？

试试这种方式.我有同样的问题,你需要提供id.

    //
    // POST: /Account/Register
    [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public async Task<ActionResult> Register(RegisterViewModel model)
    {
        if (ModelState.IsValid)
        {
            var user = new ApplicationUser() { 
                UserName = model.UserName,
                Id = Guid.NewGuid().ToString(),
                Created = DateTime.Now,
                LastLogin = null
            };

            var result = await UserManager.CreateAsync(user, model.Password);
            if (result.Succeeded)
            {
                await SignInAsync(user, isPersistent: false);
                return RedirectToAction("Index", "Home");
            }
            else
            {
                AddErrors(result);
            }



        }

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