.Net Core Identity外面使用Cookie中间件

1、在 app.UseMvc 前面加上app.UseCookieAuthentication

app.UseCookieAuthentication(new CookieAuthenticationOptions()
            {
                AuthenticationScheme = "IdeaCoreUser",
                LoginPath = new PathString("/Login/Login/"),
                AccessDeniedPath = new PathString("/Account/Forbidden/"),
                AutomaticAuthenticate = true,
                AutomaticChallenge = true,
                CookieDomain=""
            });

2、登录

var claims = new List<Claim> {
    new Claim("FullName", customer.Username,ClaimValueTypes.String),
    new Claim("Role", "注册用户",ClaimValueTypes.String),
};
var userIdentity = new ClaimsIdentity(claims, "Customer");
var userPrincipal = new ClaimsPrincipal(userIdentity);
HttpContext.Authentication.SignInAsync("IdeaCoreUser", userPrincipal,
    new AuthenticationProperties
    {
        ExpiresUtc = DateTime.UtcNow.AddMinutes(),
        IsPersistent = false,
        AllowRefresh = false
    });

3、退出登录

HttpContext.Authentication.SignOutAsync("IdeaCoreUser");

4、判断是否已经登录

var bol =HttpContext.User.Identity.IsAuthenticated;

5、使用IIdentity拓展方法来获取存的值

    public static class IdentityExtension
    {
        public static string FullName(this IIdentity identity)
        {
            var claim = ((ClaimsIdentity)identity).FindFirst("FullName");
            return (claim != null) ? claim.Value : string.Empty;
        }
        public static string Role(this IIdentity identity)
        {
            var claim = ((ClaimsIdentity)identity).FindFirst("Role");
            return (claim != null) ? claim.Value : string.Empty;
        }
    }

var fullname = HttpContext.User.Identity.FullName();
