问题描述

如何从ASP.NET MVC 4应用程序中注销特定用户?我更喜欢使用User.Id属性来执行此操作.

How can I logout a specific user from my ASP.NET MVC 4 application? I prefer to perform this with the User.Id property.

推荐答案

基于您的评论，您的问题在于更改/更新/添加一个人的角色，但是您希望通过注销该人来体现这一点. 由于该添加/更改，新角色不会反映在用户的cookie中，而只会反映在数据库中.这就是他需要注销并再次登录才能进行此修改的原因.

Well, your problem, based on your comments, is about changing/updating/adding a person's role, but you wish to reflect this by logging him out. Because of that addition/change, the new role is not reflected into user's cookie, only in the database. That is the reason he needs to be log out and login again in order this modification to take place.

本质上，如果您正在使用cookie身份验证，那么在Startup.Auth.cs中尝试该操作如何:

Essentially, if you are using cookie authentication, what about trying this in your Startup.Auth.cs:

app.UseCookieAuthentication(new CookieAuthenticationOptions {
    AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
    LoginPath = new PathString("/Account/Login"),
    Provider = new CookieAuthenticationProvider {
        // Enables the application to validate the security stamp when the user logs in.
        // This is a security feature which is used when you change a password or add an external login to your account.  
        OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<ApplicationUserManager, ApplicationUser>(
            validateInterval: TimeSpan.FromMinutes(1),
            regenerateIdentity: (manager, user) => user.GenerateUserIdentityAsync(manager))
    }
});

使用OnValidateIdentity将每隔validateInterval分钟验证一次用户请求，因此在上方的代码中，Cookie将每1分钟更新一次.如果提供TimeSpan.FromMinutes(0)，则表示cookie将根据每个用户的请求进行更新.

Using the OnValidateIdentity will validate user's request every validateInterval minutes, so in the code above the cookie will be updated every 1 minute. If you provide a TimeSpan.FromMinutes(0) will mean that the cookie will be updated in each user's request.
