MVC 5 AddToRole需要注销它工作过吗？ [英] MVC 5 AddToRole requires logout before it works?

问题描述

我发现，如果我将用户添加到在ASP中身份的作用，它没有，直到我注销并重新登录才能生效。有什么我需要做的刷新用户的角色，不强制用户先注销？

I'm finding that if I add a user to a role in ASP Identity, it doesn't take effect until I log out and log back in. Is there something I need to do to refresh a user's roles without forcing a user to log off first?

下面是我如何将用户添加到角色。

Here's how I'm adding the user to the role.

var userManager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(new ApplicationDbContext()));
var userId = HttpContext.Current.User.Identity.GetUserId();

userManager.AddToRole(userId, roleName);

然后，几乎立刻，我将用户重定向到这个操作方法。我可以说我已经加入到正确的角色数据库中告诉我们，但仍MVC我重定向到登录页面。不过，如果我注销，重新登录，并尝试去这个操作方法，它工作得很好。

Then, almost immediately, I redirect the user to this action method. I can tell in the database that I've been added to the correct role, but MVC still redirects me to the login page. However, if I log out, log back in, and attempt to go to this action method, it works just fine.

    [Authorize(Roles = RecoveryStandardRoles.ServiceProvider)]

    public partial class CertifyController : Controller

{
    #region Public Methods and Operators

    public virtual ActionResult CompanyProfile()
    {
        return this.View();
    }

    #endregion
}

感谢您抽出时间来看看我的问题！

Thank you for taking time to look at my question!

推荐答案

@凯文 - 荣汉斯你的回答使我对正确的答案。这code显示了如何将用户在MVC 5添加到角色，并自动获得该角色生效。

@kevin-junghans your answer lead me to the correct answer. This code shows how to add a user to a role in MVC 5 and to have that role automatically take effect.

var userManager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(new ApplicationDbContext()));
var userId = HttpContext.Current.User.Identity.GetUserId();

userManager.AddToRole(userId, roleName);

var authenticationManager = HttpContext.Current.GetOwinContext().Authentication;

authenticationManager.SignOut(DefaultAuthenticationTypes.ExternalCookie);

var user = userManager.FindById(userId);
var identity = userManager.CreateIdentity(user, DefaultAuthenticationTypes.ApplicationCookie);

authenticationManager.SignIn(new AuthenticationProperties { IsPersistent = false }, identity);
