“令牌无效”错误，同时电子邮件确认 ASP.NET MVC

我正在尝试将注册和登录逻辑封装到MVC中的文件中。一切正常，但我总是收到"无效令牌"。 电子邮件确认程序后出错 :(

拜托，你能帮忙吗？在寻找解决方案两天后，我变得疯狂了！

我注意到 GenerateEmailConfirmationToken 方法总是生成不同的令牌，因为它显示在日志文件中。可以吗？如果未存储令牌，则它应该始终相同，对吗？

这是我准备 ASP.NET 管理器的存储库构造函数：

    UserStore<MyUser> store = null;
    UserManager<MyUser, string> userManager = null;
    SignInManager<MyUser, string> signInManager = null;
    IAuthenticationManager authenticationManager = null;
    AbstractLogger logger = AbstractLogger.GetInstance();
public MyUserRepository(MyDbContext context) : base(context)
        {
            store = new UserStore<MyUser>(context);
            userManager = new UserManager<MyUser>(store);
            authenticationManager = HttpContext.Current.GetOwinContext().Authentication;
            signInManager = new SignInManager<MyUser, string>(userManager, authenticationManager);
            userManager.PasswordValidator = new PasswordValidator()
            {
                RequireDigit = false,
                RequiredLength = 6,
                RequireLowercase = false,
                RequireNonLetterOrDigit = false,
                RequireUppercase = false
            };
            userManager.UserValidator = new UserValidator<MyUser>(userManager)
            {
                RequireUniqueEmail = true,
                AllowOnlyAlphanumericUserNames = true
            };
            // Configure user lockout defaults
            userManager.UserLockoutEnabledByDefault = true;
            userManager.DefaultAccountLockoutTimeSpan = TimeSpan.FromMinutes(5);
            userManager.MaxFailedAccessAttemptsBeforeLockout = 5;
            userManager.EmailService = new EmailService();

            var provider = new DpapiDataProtectionProvider("MyApp.org");
            userManager.UserTokenProvider = new DataProtectorTokenProvider<MyUser, string>(provider.Create("UserToken")) as IUserTokenProvider<MyUser, string>;
        }

以下是注册方法：

public void Register(MyUser user, string password)
        {
            IdentityResult result = userManager.Create(user, password);
            //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 = string.Empty;
            for (int i = 0; i < 10; i++)
            {
                code = userManager.GenerateEmailConfirmationToken(user.Id);
                logger.LogInfo("USER: " + user.Id + " CODE: " + code);
            }

            logger.LogInfo(
                string.Format(
                "New user {0}; {1}; {2}",
                user.Email,
                user.Id,
                code
                ));

            string callbackUrl = string.Format("http://localhost:5320/Account/ConfirmEmail?userId={0}&code={1}", user.Id, code); // }, protocol: HttpContext.Current.Request.Url.Scheme);
            userManager.SendEmail(user.Id, "Potvrzení registrace", "Please confirm your account by clicking <a href='"" + callbackUrl + "'">here</a>");
        }

这是确认方法：

    public IdentityResult ConfirmEmail(string userId, string code)
            {
                return userManager.ConfirmEmail(userId, code);
            }

以下是日志输出：
