使用ClaimsIdentity来实现登录授权

背景:以前做登录时用的都是FormsAuthentication.SetAuthCookie(model.UID, IsRemeber),但是有一个不好,不能存储多个值,有时候我们既想存储登录用户的UID又想存储用户名,以前都是将两者拼接成字符串,用的时候在split出来,比较麻烦,现在用ClaimsIdentity就很方便。

1、登录时验证通过存储

  ClaimsIdentity ci = new ClaimsIdentity(DefaultAuthenticationTypes.ApplicationCookie);
                    ci.AddClaim(new Claim(ClaimsIdentity.DefaultNameClaimType, model.UserName));
                    ci.AddClaim(new Claim(ClaimTypes.NameIdentifier, model.UID));
                    ci.AddClaim(new Claim("HspUID", model.HspUID));
                    AuthenticationManager.SignIn(new AuthenticationProperties { IsPersistent = IsRemeber }, ci);

需要用到下面的

 private IAuthenticationManager AuthenticationManager
        {
            get
            {
                return HttpContext.GetOwinContext().Authentication;
            }
        }

2、获取值

//获取UID
User.Identity.GetUserId();
//获取Name
User.Identity.Name;
//获取HspUID
var claimIdentity = (ClaimsIdentity)User.Identity;
var HspUID = claimIdentity.FindFirstValue("HspUID");

3、App_Start里创建Startup.Auth.cs

using Microsoft.AspNet.Identity;
using Microsoft.Owin;
using Microsoft.Owin.Security.Cookies;
using Owin;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace Yuwell.PressureManage.Web
{
    public partial class Startup
    {
        public void ConfigureAuth(IAppBuilder app)
        {


            // 使应用程序可以使用 Cookie 来存储已登录用户的信息
            // 并使用 Cookie 来临时存储有关使用第三方登录提供程序登录的用户的信息
            // 配置登录 Cookie
            app.UseCookieAuthentication(new CookieAuthenticationOptions
            {
                AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
                LoginPath = new PathString("/Account/Login"),              
            });
       
        }
    }
}

4、Web项目里添加Startup类

using Hangfire;
using Hangfire.MemoryStorage;
using Microsoft.Owin;
using Owin;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

[assembly: OwinStartupAttribute(typeof(Test.Web.Startup))]
namespace Yuwell.PressureManage.Web
{
    public partial class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            ConfigureAuth(app);
            GlobalConfiguration.Configuration.UseMemoryStorage();
            app.UseHangfireServer();
            app.UseHangfireDashboard();
        }
    }
}

 

需要用到的包

 记得Web.config里configSections节点下加下面的配置

  <system.webServer>
    <modules>
      <remove name="FormsAuthentication" />
    </modules>
  </system.webServer>

好了,好像就这么多了,结束!!!!!!
