我正在使用Web API 2，并且希望使用Microsoft ASP.NET Identity 2.2.2保护我的api；一切都很好，直到我为数据库中的用户启用2fa。
这样做之后，当我在signInHelper方法的GetVerifiedUserIdAsync类中跟踪代码时，结果始终为空。

// Enable the application to use a cookie to store information for the signed in user
// and to use a cookie to temporarily store information about a user logging in with a third party login provider

// Enable the application to use bearer tokens to authenticate users
app.UseOAuthBearerTokens(OAuthOptions);
// Enables the application to temporarily store user information when they are verifying the second factor in the two-factor authentication process.
app.UseTwoFactorSignInCookie(DefaultAuthenticationTypes.TwoFactorCookie, TimeSpan.FromMinutes(5));
// Enables the application to remember the second login verification factor such as phone or email.
// Once you check this option, your second step of verification during the login process will be remembered on the device where you logged in from.
// This is similar to the RememberMe option when you log in.
