MVC6 OWin Microsoft Identity 自定义验证

1、 Startup.cs中修改默认的验证设置

            //app.UseIdentity();

            app.UseCookieAuthentication(options => {
                //options.AuthenticationScheme = CookieAuthenticationDefaults.AuthenticationScheme;// "MyCookieMiddlewareInstance";
                options.LoginPath = new PathString("/Account/Unauthorized/");
                options.AccessDeniedPath = new PathString("/Account/Forbidden/");
                options.AutomaticAuthenticate = true;
                options.AutomaticChallenge = true;
            });

using System.Security.Claims;
using Microsoft.AspNet.Authentication.Cookies;
using Microsoft.AspNet.Identity;

2、Controller中的登录代码

        public async Task<IActionResult> Login()
        {
            var claims = new List<Claim>();
            claims.Add(new Claim(ClaimTypes.Name, "Admin"));   // value of this.User.GetUserName() or  this.User.Identity.Name
            claims.Add(new Claim(ClaimTypes.NameIdentifier, "10001"));  // value of  this.User.GetUserId();
            claims.Add(new Claim("SelfDefined1", "value1"));

            var ci = new System.Security.Claims.ClaimsIdentity(claims, IdentityCookieOptions.ApplicationCookieAuthenticationType);
            var cp = new System.Security.Claims.ClaimsPrincipal(ci); 
              
            await HttpContext.Authentication.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme, cp );

            return View("Index");
        }

注意，在创建ClaimsIdentity时， AuthenticationType 参数是必须的。

因为 this.User.IsSignedIn(); 是靠这个参数带验证是否登录的。

3、Controller中取登录信息的代码：

            bool signed = this.User.IsSignedIn();
            string userName = this.User.Identity.Name;
            userName = this.User.GetUserName();

为了使用方便，常定义一些  ClaimsPrincipal（this.User） 的扩展方法来取各种登录时保存的变量。
