此代码之前曾多次运行，但在为 Identity 2.1 中的用户添加了几个新属性后，它突然停止运行。我收到一个 UserId not found 错误，尽管在调试器中有一个 UserId 的可见值。任何人都知道为什么会突然发生这种情况？看到最少的东西是非常令人沮丧的。

代码如下: ( Controller )

 // 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);
    }

和模型:

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.

最佳答案

现在有同样的错误! 我最近所做的唯一相关操作是更新包 通过 NuGet:

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

无论如何仍在调查......

更新

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

希望这能以某种方式有所帮助。

关于c# - Identity 2.1 - 未找到 UserId 但之前在工作，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/30354508/
