我正在实施asp.net身份。我使用int主键而不是默认String覆盖了默认类。我按照以下文章进行了操作：Article
很抱歉所有的代码，但是我已经坚持了一段时间这个愚蠢的错误，所以我宁愿给出更多的信息而不是更少。
我有以下课程：
public class FskUser : IdentityUser<int, FskUserLogin, FskUserRole, FskUserClaim>
{
...
public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<FskUser, 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;
}
}
我的自定义SignInManager
public class FskSignInManager : SignInManager<FskUser,int>
{
public FskSignInManager(FskUserManager userManager, IAuthenticationManager authenticationManager)
: base(userManager, authenticationManager)
{
}
public override Task<ClaimsIdentity> CreateUserIdentityAsync(FskUser user)
{
return user.GenerateUserIdentityAsync((FskUserManager)UserManager);
}
public static FskSignInManager Create(IdentityFactoryOptions<FskSignInManager> options, IOwinContext context)
{
return new FskSignInManager(context.GetUserManager<FskUserManager>(), context.Authentication);
}
}
我的StartUp.Auth.cs
public void ConfigureAuth(IAppBuilder app)
{
// Configure the db context, user manager and signin manager to use a single instance per request
app.CreatePerOwinContext(IdentityDbContext.Create);
app.CreatePerOwinContext<FskUserManager>(FskUserManager.Create);
app.CreatePerOwinContext<FskSignInManager>(FskSignInManager.Create);
// Enable the application to use a cookie to store information for the signed in user
// and to use a cookie to temporarily store information about a user logging in with a third party login provider
// Configure the sign in cookie
app.UseCookieAuthentication(new CookieAuthenticationOptions
{
AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
LoginPath = new PathString("/Account/Login"),
Provider = new CookieAuthenticationProvider
{
// Enables the application to validate the security stamp when the user logs in.
// This is a security feature which is used when you change a password or add an external login to your account.
OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<FskUserManager, FskUser, int>(
validateInterval: TimeSpan.FromMinutes(30),
regenerateIdentityCallback: (manager, user) =>
user.GenerateUserIdentityAsync(manager),
getUserIdCallback: (id) => (id.GetUserId<int>()))
}
}); app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);
}
这是我的帐户控制器简化：
[Authorize]
public class AccountController : Controller
{
private FskSignInManager _signInManager;
private FskUserManager _userManager;
public AccountController()
{
}
public AccountController(FskUserManager userManager, FskSignInManager signInManager)
{
UserManager = userManager;
SignInManager = signInManager;
}
public FskSignInManager SignInManager
{
get
{
if (_signInManager == null)
{
//split for debug purposes
var cntx = HttpContext.GetOwinContext();
var tmp = cntx.Get<FskSignInManager>();
return tmp;
}
else
{
return _signInManager;
}
}
private set
{
_signInManager = value;
}
}
public FskUserManager UserManager
{
get
{
return _userManager ?? HttpContext.GetOwinContext().GetUserManager<FskUserManager>();
}
private set
{
_userManager = value;
}
}
//
// POST: /Account/Login
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Login(LoginViewModel model, string returnUrl)
{
if (!ModelState.IsValid)
{
return View(model);
}
*** line below causes the error ***
var result = await SignInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe, shouldLockout: false);
switch (result)
{
case SignInStatus.Success:
return RedirectToLocal(returnUrl);
case SignInStatus.LockedOut:
return View("Lockout");
case SignInStatus.RequiresVerification:
return RedirectToAction("SendCode", new { ReturnUrl = returnUrl, RememberMe = model.RememberMe });
case SignInStatus.Failure:
default:
ModelState.AddModelError("", "Invalid login attempt.");
return View(model);
}
}
}

对我而言，这是null ClaimValue
的结果user.Claims.Add(new IdentityUserClaim<string>
{
ClaimType = item.Key,
ClaimValue = item.Value
});
我通过将代码修改为
解决了这个问题user.Claims.Add(new IdentityUserClaim<string>
{
ClaimType = item.Key,
ClaimValue = item.Value != null ? item.Value : ""
});

我坚持SignInManager无法以相同的错误登录新创建的用户。
解决方案：
我发现，仅在创建角色时向用户提供角色即可解决问题。
await userManager.AddToRoleAsync(user, UserRoles.Basic.ToString());
