ASP.NET核心身份和饼干 [英] ASP.NET Core Identity & Cookies

问题描述

我有一个使用AspNetCore.Identity.EntityFrameworkCore 1.1.1和cookie来授权/验证我的用户的ASP.NET Core网站.不管我在下面的代码中选择什么设置，cookie都会在20分钟后过期，我不知道为什么.除非您关闭浏览器并清除历史记录/Cookie，否则网站将无法正常工作.有什么想法吗?

I have an ASP.NET Core site using AspNetCore.Identity.EntityFrameworkCore 1.1.1 and cookies to authorize/authenticate my users. No matter what I choose as my setting in the code below, the cookie expires after about 20 minutes and I can't figure why. The website will then no longer work unless you close the browser and clear the history/cookies. Any ideas?

services.AddIdentity<ApplicationUser, IdentityRole>(config =>
{
    //  Require a confirmed email in order to log in
    config.SignIn.RequireConfirmedEmail = true;
})
    .AddEntityFrameworkStores<ApplicationDbContext>()
    .AddDefaultTokenProviders();

app.UseIdentity();

//  Add cookie middleware to the configure an identity request and persist it to a cookie.
app.UseCookieAuthentication(new CookieAuthenticationOptions
{
    AuthenticationScheme = "Cookie",
    LoginPath = new PathString("/Account/Login/"),
    AccessDeniedPath = new PathString("/Account/Forbidden/"),
    AutomaticAuthenticate = true,
    AutomaticChallenge = true,
    ExpireTimeSpan = TimeSpan.FromMinutes(20),
    SlidingExpiration = true,

});

我还有一些剃须刀代码，用于控制是否在_layout页面上显示管理菜单.当Cookie过期时，这会崩溃，因为用户突然没有任何声明.有更好的方法来解决这个问题吗?

I also have some razor code that controls whether to show the admin menu on the _layout page. This crashes when the cookie expires as the users suddenly has no claims. Is there a better way to handle this?

// If user is admin then show drop down with admin navigation
@if (User.HasClaim(System.Security.Claims.ClaimTypes.Role, "admin"))
{
    <ul class="nav navbar-nav">
        @*etc*@
    </ul>
}

推荐答案

在使用ASPNET身份时，您不需要单独的CookieAuthentication中间件. UseIdentity()将为您执行此操作并生成一个cookie.您可以像这样在应用程序的AddIdentity块中设置"cookie options":

You do not need a separate CookieAuthentication middleware when you are using ASPNET identity. UseIdentity() will do that for you and generate a cookie. You can set the "cookie options" in the AddIdentity block of the application like so:

     services.AddIdentity<ApplicationUser, IdentityRole>(config =>
            {
                //  Require a confirmed email in order to log in
                config.SignIn.RequireConfirmedEmail = true;

               // Your Cookie settings
              config.Cookies.ApplicationCookie.ExpireTimeSpan = TimeSpan.FromDays(1);
              config.Cookies.ApplicationCookie.LoginPath = "/Account/LogIn";
              config.Cookies.ApplicationCookie.LogoutPath = "/Account/LogOut";
            }).AddEntityFrameworkStores<ApplicationDbContext().AddDefaultTokenProviders();
