Question

此代码在很多次之前有效，但在为Identity 2.1中的用户添加了几个新属性后，它已经停止工作。我收到UserId未找到错误，尽管在UserId的调试器中可以看到一个值。任何人都知道为什么突然发生这种情况？至少看到它是非常令人沮丧的。

这里的代码：（控制器）

 // POST: /Account/Register
    [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public async Task<ActionResult> Register(RegisterViewModel model)
    {
        model.BackgroundOnFile = false;

        if (ModelState.IsValid)
        {
            var userDetails = new ApplicationUser { UserName = model.Email, Title = model.Title, Email = model.Email, FirstName = model.FirstName, LastName = model.LastName, LEAID = model.LEAID, SchoolID = model.SchoolID, Address1 = model.Address1, Address2 = model.Address2, City = model.City, State = model.State, PostCode = model.PostCode, BackgroundOnFile = model.BackgroundOnFile, BoardStart = model.BoardStart, BoardEnd = model.BoardEnd, PhoneNumber = model.PhoneNumber };
            var result = await UserManager.CreateAsync(userDetails, model.Password);


            //Assign Role
            UserManager.AddToRole(userDetails.Id, "User");

            if (result.Succeeded)
            {
                await SignInManager.SignInAsync(userDetails, isPersistent:false, rememberBrowser:false);

                // For more information on how to enable account confirmation and password reset please visit http://go.microsoft.com/fwlink/?LinkID=320771
                // Send an email with this link
                // string code = await UserManager.GenerateEmailConfirmationTokenAsync(user.Id);
                // var callbackUrl = Url.Action("ConfirmEmail", "Account", new { userId = user.Id, code = code }, protocol: Request.Url.Scheme);
                // await UserManager.SendEmailAsync(user.Id, "Confirm your account", "Please confirm your account by clicking <a href=\"" + callbackUrl + "\">here</a>");

                return RedirectToAction("Index", "Home");
            }
            AddErrors(result);
        }

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

模特：

public class ApplicationUser : IdentityUser
{

    //Extra items required to register
    public string Title { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public int LEAID { get; set; }
    public int SchoolID { get; set; }
    public string Address1 { get; set; }
    public string Address2 { get; set; }
    public string City { get; set; }
    public string State { get; set; }
    //Post Code is a string to accomodate future possible Canadian style post codes
    public string PostCode { get; set; }
    public bool BackgroundOnFile { get; set; }
    public System.DateTime BoardStart { get; set; }
    public System.DateTime BoardEnd { get; set; }
    public string NominatedBy { 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;
    }
}

错误：

UserId not found.

Answer 1

现在有同样的错误！我最近采取的唯一相关措施是更新套餐通过NuGet：

EntityFramework 6.1.1至6.1.3
Microsoft ASP.NET IdentityCore 2.1.0至2.2.1
Microsoft ASP.NET Identity EntityFramework 2.1.0到2.2.1
Microsoft ASP.NET Identity Owin 2.1.0至2.2.1

仍在调查......

<强>更新

在我的情况下，我试图在保存用户之前生成确认令牌。我了解到UserManager.GenerateEmailConfirmationTokenAsync(userID)在保存的ID上生成令牌，而不是在内存中生成令牌。

希望这会有所帮助。

Answer 2

Application User类不生成此异常，此类中没有名为UserID的属性。（Id而非UserId）

因此，Identity数据库中有两个表包含UserID

列

IdentityRole
IdentityUserRole

因此，在这些表中插入期间会引发异常，ApplicationUser.Id没有任何问题。确保该角色名称为＆＃34; User＆＃34;存在。还要检查姓名案例，即"User"/"user"

Answer 3

如果像我一样，你很难在不完全理解所有细节的情况下让身份框架工作，这可能会有所帮助。我正在使用此行来获取对用户的引用：

var user = new ApplicationUser { UserName = ...

这会创建一个新用户。我应该做的就是使用这一行：

var user = UserManager.FindByEmail( ...

然后您可以重置密码：

string code = UserManager.GeneratePasswordResetToken(user.Id);
var result = UserManager.ResetPassword(user.Id, code, model.Password);

请注意，这没有错误检查。

身份2.1 - UserId未找到但之前正在工作
