我一直在尝试使用Visual Studio 2013在ASP.NET 4.5(Microsoft.AspNet.Identity)中实现新的Identity功能的自定义版本。经过许多个小时的播放，我已经简化了我的代码努力让它运行没有错误。我在下面列出了我的代码做本地注册时，创建数据库表，但CreateLocalUser方法失败。我希望有人可以帮助我识别所需的变化。
Models / MembershipModel.cs
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>
{
}
}
对控制器/ AccountController.cs的更改
public AccountController()
{
IdentityStore = new IdentityStoreManager(new PulseUserContext(new PulseDbContext()));
AuthenticationManager = new IdentityAuthenticationManager(IdentityStore);
}
//
// POST: /Account/Register
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Register(Register@R_404_93@l 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);
}
如上所述，当CreateLocalUser方法失败(Microsoft.AspNet.Identity.EntityFramework)时，此实现将失败。我不知道为什么。
解决方法
这里的问题是IdentityStoreManager对身份EF模型的默认实现有很强的依赖性。例如，CreateLocalUser方法将创建UserSecret和UserLogin对象并将其保存到存储中，如果存储不使用默认模型类型，则不起作用。因此，如果您自定义模型类型，它将无法顺利使用IdentityStoreManager。
由于您只自定义IUser模型，所以我简化了代码以从默认身份用户继承自定义用户，并从身份EF模型重用其他模型。
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>
{
}
}
上述代码可以使用Identity API的预览版本。
即将发布的IdentityStoreManager API已经意识到此问题，并将所有非EF依赖代码更改为基类，以便您可以通过继承来自定义它。应该解决这里的一切问题。谢谢。
