如何阅读MVC OWIN AuthenticationProperties? [英] How to read MVC OWIN AuthenticationProperties?

问题描述

我在登录用户时正在设置IsPersistent，如何读回该值?

I'm setting IsPersistent when signing the user in, how to read that value back?

var identity = await UserManager.CreateIdentityAsync(appUser, DefaultAuthenticationTypes.ApplicationCookie);
HttpContext.GetOwinContext().Authentication.SignIn(new AuthenticationProperties() { IsPersistent = false }, identity);

推荐答案

AspNet.Identity使您可以访问会话的IsPersistent的bool值.读取其值的最直接方法是调用AuthenticateAsync():

AspNet.Identity gives you access to the bool value of IsPersistent for the session. The most direct way to read its value is to call AuthenticateAsync():

@using Microsoft.AspNet.Identity;
var authenticateResult = await HttpContext.GetOwinContext()
                           .Authentication.AuthenticateAsync(
                               DefaultAuthenticationTypes.ApplicationCookie
                           );
var isPersistent = authenticateResult.Properties.IsPersistent; //// true or false

请注意，您需要将其包装在async方法中，例如:

Note that you will need to wrap this in an async method, such as:

@using System.Threading.Tasks;
public async Task<ActionResult> SomeMethodName(...) { //etc }
