在ASP.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(20),
                            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();
