身份2.1 -用户id没有找到，但之前工作

Question

这段代码以前工作过很多次，但是在Identity 2.1中为用户添加了几个新属性之后，它突然停止工作了。我得到一个UserId未发现错误，尽管有一个值在调试器中为UserId可见。有人知道为什么会突然发生这种事吗?

下面的代码:(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);
    }

And the Model:

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;
    }
}

和错误:

Answer 1

现在有同样的错误!我最近所做的唯一相关的操作是更新了软件包通过NuGet:

• 实体框架6.1.1至6.1.3
• 微软的ASP。. NET IdentityCore 2.1.0到2.2.1
• 微软的ASP。. NET Identity EntityFramework 2.1.0到2.2.1
• 微软的ASP。. NET Identity Owin 2.1.0到2.2.1

仍在调查…

在我的例子中，我试图在保存用户之前生成确认令牌。我了解到UserManager.GenerateEmailConfirmationTokenAsync(userID)根据保存的ID生成令牌，而不是内存中的那个。

Answer 2

此异常不是由Application User类生成的，该类中没有名为UserID的属性。(是Id不是UserId)

所以在Identity数据库中有两个表包含UserID的列

1. IdentityRole
2. IdentityUserRole

因此，在这些表中插入时引发异常，ApplicationUser.Id没有任何问题。确保名称为"User"的角色存在。还要检查名称大小写，即"User"/"user"

Answer 3

如果您像我一样，在没有充分了解所有细节的情况下努力使身份框架工作，那么这可能会有所帮助。我使用这一行来获取对用户的引用:

var user = new ApplicationUser { UserName = ...

创建一个新用户。我应该做的是使用这一行:

var user = UserManager.FindByEmail( ...

你可以像这样重置密码:

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