asp.net-mvc-5 - Store 没有实现 IUserLockoutStore

Question

我正在尝试使用我需要的功能为 asp.net Identity 2.0 实现自己的 DAL。我不需要帐户锁定功能。但是当我尝试打电话时

var result = await SignInManager.PasswordSignInAsync(model.Login, model.Password, model.RememberMe, shouldLockout: false);

我得到 System.NotSupportedException:Store does not implement IUserLockoutStore<TUser>.

那么，如果我不需要 IUserLockoutStore，为什么还需要实现它呢？

查看此答案:When implementing your own IUserStore, are the "optional" interfaces on the class actually optional?

您将需要欺骗或重写您尝试在商店中调用的方法，以实现不使用“可选”锁定商店的方法。

您可能会惊讶地发现您还需要为双因素实现“可选”接口(interface)。使用下面相同的答案来这样做，除非你确实有双因素的方法。

不过，首先，这里是默认实现:

public virtual async Task<SignInStatus> PasswordSignInAsync(string userName, string password, bool isPersistent, bool shouldLockout)
        {
           ...
            if (await UserManager.IsLockedOutAsync(user.Id).WithCurrentCulture())
            {
                return SignInStatus.LockedOut;
            }
            if (await UserManager.CheckPasswordAsync(user, password).WithCurrentCulture())
            {
                return await SignInOrTwoFactor(user, isPersistent).WithCurrentCulture();
            }
            ...
            return SignInStatus.Failure;
        }

一个答案:创建无用的商店。

    #region LockoutStore
    public Task<int> GetAccessFailedCountAsync(MyUser user)
    {
        throw new NotImplementedException();
    }

    public Task<bool> GetLockoutEnabledAsync(MyUser user)
    {
        return Task.Factory.StartNew<bool>(() => false);
    }

    public Task<DateTimeOffset> GetLockoutEndDateAsync(MyUser user)
    {
        throw new NotImplementedException();
    }

    public Task<int> IncrementAccessFailedCountAsync(MyUser user)
    {
        throw new NotImplementedException();
    }

    public Task ResetAccessFailedCountAsync(MyUser user)
    {
        throw new NotImplementedException();
    }

    public Task SetLockoutEnabledAsync(MyUser user, bool enabled)
    {
        throw new NotImplementedException();
    }

    public Task SetLockoutEndDateAsync(MyUser user, DateTimeOffset lockoutEnd)
    {
        throw new NotImplementedException();
    }
    #endregion
}

另一种解决方案:重写以不使用它。

public virtual async Task<SignInStatus> PasswordSignInAsync(string userName, string password, bool isPersistent, bool shouldLockout)
        {
           ...
            if (false)
            {
                return SignInStatus.LockedOut;
            }
            if (await UserManager.CheckPasswordAsync(user, password).WithCurrentCulture())
            {
                return await SignInOrTwoFactor(user, isPersistent).WithCurrentCulture();
            }
            ...
            return SignInStatus.Failure;
        }
