自定义成员资格与Microsoft.AspNet.Identity - CreateLocalUser失败 [英] Custom Membership with Microsoft.AspNet.Identity - CreateLocalUser fails

问题描述

我一直试图在ASP.NET 4.5（Microsoft.AspNet.Identity）实施的新的标识功能的定制版本，使用Visual Studio 2013多个小时与此玩弄后，我已经简化我的得到它运行在努力code没有错误。我在下面列出了我的code。当进行本地注册，数据库表的创建，但CreateLocalUser方法失败。我希望有人能帮助我确定所需的更改。

I've been trying to implement a custom version of the new Identity features in ASP.NET 4.5 (Microsoft.AspNet.Identity), using Visual Studio 2013. After many hours of playing around with this, I've simplified my code in an effort to get it running without errors. I've listed my code below. When doing a Local Registration, the database tables are created, but the CreateLocalUser method fails. I'm hoping that someone can help me identify the changes needed.

using Microsoft.AspNet.Identity;
using Microsoft.AspNet.Identity.EntityFramework;
using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;
using System.Data.Entity;
using System.Linq;
using System.Web;

namespace thePulse.web.Models
{
    public class PulseUser : IUser
    {
        public PulseUser() { }
        public PulseUser(string userName) 
        {
            UserName = userName;
        }

        [Key]
        public string Id { get; set; }
        [Required]
        [StringLength(20)]
        public string UserName { get; set; }
        [StringLength(100)]
        public string Email { get; set; }
        [Column(TypeName = "Date")]
        public DateTime? BirthDate { get; set; }
        [StringLength(1)]
        public string Gender { get; set; }
    }

    public class PulseUserClaim : IUserClaim
    {
        public PulseUserClaim() { }

        [Key]
        public string Key { get; set; }
        public string UserId { get; set; }
        public string ClaimType { get; set; }
        public string ClaimValue { get; set; }

    }

    public class PulseUserSecret : IUserSecret
    {
        public PulseUserSecret() { }
        public PulseUserSecret(string userName, string secret)
        {
            UserName = userName;
            Secret = secret;
        }

        [Key]
        public string UserName { get; set; }
        public string Secret { get; set; }

    }

    public class PulseUserLogin : IUserLogin
    {
        public PulseUserLogin() { }
        public PulseUserLogin(string userId, string loginProvider, string providerKey) 
        {
            LoginProvider = LoginProvider;
            ProviderKey = providerKey;
            UserId = userId;
        }

        [Key, Column(Order = 0)]
        public string LoginProvider { get; set; }
        [Key, Column(Order = 1)]
        public string ProviderKey { get; set; }
        public string UserId { get; set; }
    }

    public class PulseRole : IRole
    {
        public PulseRole() { }
        public PulseRole(string roleId)
        {
            Id = roleId;
        }

        [Key]
        public string Id { get; set; }
    }

    public class PulseUserRole : IUserRole
    {
        public PulseUserRole() { }

        [Key, Column(Order = 0)]
        public string RoleId { get; set; }
        [Key, Column(Order = 1)]
        public string UserId { get; set; }
    }

    public class PulseUserContext : IdentityStoreContext
    {
        public PulseUserContext(DbContext db) : base(db)
        {
            Users = new UserStore<PulseUser>(db);
            Logins = new UserLoginStore<PulseUserLogin>(db);
            Roles = new RoleStore<PulseRole, PulseUserRole>(db);
            Secrets = new UserSecretStore<PulseUserSecret>(db);
            UserClaims = new UserClaimStore<PulseUserClaim>(db);
        }
    }

    public class PulseDbContext : IdentityDbContext<PulseUser, PulseUserClaim, PulseUserSecret, PulseUserLogin, PulseRole, PulseUserRole>
    {
    }
}

更改控制器/ AccountController.cs

public AccountController() 
{

    IdentityStore = new IdentityStoreManager(new PulseUserContext(new PulseDbContext()));
    AuthenticationManager = new IdentityAuthenticationManager(IdentityStore);
}

//
// POST: /Account/Register
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Register(RegisterViewModel model)
{
    if (ModelState.IsValid)
    {
        try
        {
            // Create a profile, password, and link the local login before signing in the user
            PulseUser user = new PulseUser(model.UserName);
            if (await IdentityStore.CreateLocalUser(user, model.Password))
            {
                await AuthenticationManager.SignIn(HttpContext, user.Id, isPersistent: false);
                return RedirectToAction("Index", "Home");
            }
            else
            {
                ModelState.AddModelError("", "Failed to register user name: " + model.UserName);
            }
        }
        catch (IdentityException e)
        {
            ModelState.AddModelError("", e.Message);
        }
    }

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

正如我前面所说，这种实现当CreateLocalUser方法失败（Microsoft.AspNet.Identity.EntityFramework）失败。我想不通为什么。

As I said above, this implementation fails when the CreateLocalUser method fails (Microsoft.AspNet.Identity.EntityFramework). I cannot figure out why.

推荐答案

这里的问题是，IdentityStoreManager对身份EF模型的默认实现很强的依赖性。例如，CreateLocalUser方法将创建UserSecret和用户登陆的对象，并将它们保存到商店，如果商店是不使用默认模式类型，将无法正常工作。所以，如果你定制机型，它不会顺利，IdentityStoreManager工作。

The issue here is that IdentityStoreManager has strong dependency on the default implementation of identity EF models. For example, the CreateLocalUser method will create UserSecret and UserLogin objects and save them to stores, which won't work if the store is not using the default model type. So if you customize the model type, it won't work smoothly with IdentityStoreManager.

由于您只定制IUSER模式，我简化了code继承从默认用户身份的自定义用户和身份EF车型重用等车型。

Since you only customize the IUser model, I simplified the code to inherit custom user from default identity user and reuse other models from identity EF models.

using Microsoft.AspNet.Identity;
using Microsoft.AspNet.Identity.EntityFramework;
using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;
using System.Data.Entity;
using System.Linq;
using System.Web;

namespace WebApplication11.Models
{
    public class PulseUser : User
    {
        public PulseUser() { }
        public PulseUser(string userName) : base(userName)
        {
        }

        [StringLength(100)]
        public string Email { get; set; }
        [Column(TypeName = "Date")]
        public DateTime? BirthDate { get; set; }
        [StringLength(1)]
        public string Gender { get; set; }
    }

    public class PulseUserContext : IdentityStoreContext
    {
        public PulseUserContext(DbContext db) : base(db)
        {
            this.Users = new UserStore<PulseUser>(this.DbContext);
        }
    }

    public class PulseDbContext : IdentityDbContext<PulseUser, UserClaim, UserSecret, UserLogin, Role, UserRole>
    {
    }
}

在code以上应与身份API的preVIEW版本。

The code above should work with preview version of Identity API.

在即将发布的IdentityStoreManager API已经意识到这个问题，并且改变了所有的非EF依赖code到一个基类，这样你可以从它继承自定义。它应该在这里解决所有的问题。谢谢你。

The IdentityStoreManager API in upcoming release is already aware of this issue and changed all the non-EF dependency code into a base class so that you can customize it by inheriting from it. It should solve all the problems here. Thanks.
