身份2.1 – 未找到UserId但之前正在使用

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值。 任何人都知道为什么会突然发生这种情况？ 至少看到它是非常令人沮丧的。

这是代码:(控制器）

// POST: /Account/Register [HttpPost] [AllowAnonymous] [ValidateAntiForgeryToken] public async Task 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 here"); return RedirectToAction("Index", "Home"); } AddErrors(result); } // If we got this far, something failed, redisplay form return View(model); } 

而型号：

 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 GenerateUserIdentityAsync(UserManager 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; } } 

而错误：

Answer 1

现在有同样的错误！ 我最近采取的相关行动是通过NuGet更新软件包：

• EntityFramework 6.1.1至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

还在调查……

UPDATE

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的令牌。

希望这会有所帮助，不知何故。

Answer 2

Application User类不生成此exception，此类中没有名为UserID属性。 （它的Id不是UserId ）

因此， Identity数据库中有两个表包含具有UserID列

1. IdentityRole
2. IdentityUserRole

因此，在这些表中插入期间会引发exception， ApplicationUser.Id没有任何问题。 确保名称为“User”的角色存在。 还检查名称案例即"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使身份框架工作，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。 我应该做的是使用这一行：

 var user = UserManager.FindByEmail( ... 

然后，您可以重置密码，如下所示：

 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。
