摘要: 两个概念:1、OWIN的英文全称是Open Web Interface for .NET。.NET开放的Web接口。2、Microsoft.AspNet.Identity是微软在MVC 5.0中新引入的一种membership框架,和之前ASP.NET传统的membership以及WebPage所带来的SimpleMembership(在MVC 4中使用)都有所不同。本文以自定义数据库表来实现用户的登录授权。不依赖MemberShip和EF框架。

关于AspNet.Identity,参考:http://www.cnblogs.com/shanyou/p/3918178.html

关于OWIN,可以阅读:http://www.cnblogs.com/dudu/p/what-is-owin.html

  OWIN使ASP.NET应用运行在其它平台上称为可能。对ASP.NET程序和IIS进行解耦。我们可以在没有安装IIS的情况下,运行ASP.NET程序。在这里http://katanaproject.codeplex.com/可以下载源码。

  另一个概念就是基于声明(Claim)的认证机制。


什么是Claims-based(基于声明)的认证

    首先,这种机制并非微软特有的,Claims-based认证和授权在国外被广泛使用,包括微软的ADFS,Google,Facebook等。


Claims-based认证的主要特点:

  • 将认证与授权拆分成独立的服务
  • 服务调用者(一般是网站),不需要关注你如何去认证,你用Windows认证也好,用令牌手机短信也好,与我无关。
  • 如果用户成功登录的话,认证服务(假如是QQ) 会返回给我们一个令牌。
  • 令牌当中包含了服务调用者所需要的信息,用户名,以及角色信息等等。
     总的来说就是,我再也不用管你怎么登录,怎么样去拿你有哪些角色了,我只需要把你跳到那个登录站点上,然后它返回给我令牌信息,我从令牌上获取需要的信息来确定你是谁,你拥有什么角色就可以了。


    接下来,我们会使用到两个对象Microsoft.AspNet.Identity.UserManager和Microsoft.AspNet.Identity.Owin.SignInManager,当然,在不使用Microsoft.AspNet.Identity.Owin.SignInManager的情况下,我们依然可以完成认证工作。在这里,我手动创建了两个类,分别集成前两个类。代码如下:


TiKuSignInManager 类:

                }

                if (ByteEqual(buffer3, buffer4))
                {

                }

                if (b1 == null || b2 == null) return false;
                for (int i = 0; i < b1.Length; i++)
                {
                    if (b1[i] != b2[i])
                    {
                        return false;
                    }
                }
                return true;
            }
        }
    }
}
这两个类,为我们提供了用户认证常用的方法。接下来,你在创建UserManager类的时候,发现,需要提供Microsoft.AspNet.Identity.IUserStore<TiKuUser, Guid>类型对象来构造UserManager对象,于是我继承了这个Microsoft.AspNet.Identity.IUserStore<TiKuUser, Guid>接口:

using System.Collections.Generic;
using System.Data;
using System.Data.SqlClient;
using System.Linq;
using System.Threading.Tasks;

下面,我们看看注册方法该怎么写,在这里,我用MVC5作为代码示例,在解决方案中,创建AccountController控制器:
[Authorize]
    public class AccountController : Controller
    {

        /// <summary>
        ///注册:这里省事,没有写UI
        /// </summary>
        /// <param name="user"></param>
        /// <returns></returns>
        [AllowAnonymous]
        public async Task<ActionResult> Register()
        {

            //user
            TiKuUser user = new TiKuUser { Id = Guid.NewGuid(), UserName = "chaoqiangli", Password = "XXXX" };

            //Context
            Microsoft.Owin.IOwinContext OwinContext = HttpContext.GetOwinContext();

            //用户储存
            Models.TiKuUserStore userStore = new Models.TiKuUserStore();

            //UserManager
            TiKuUserManager UserManager = new TiKuUserManager(userStore);

            IdentityResult result = await UserManager.CreateAsync(user, user.Password);
            if (result.Succeeded)
            {
                Response.Write("注册成功!");
            }
            return View();
        }
}




我们来看看,Models.TiKuUserStore 对象都完成了那些工作。

        }
    }
}
现在,我们可以编写用户注册的方法了,这是,我们会用到另一个对象,TiKuUser,它继承自Microsoft.AspNet.Identity.IUser<Guid>接口,根据实际情况,我们可以去拓展它。



using Microsoft.AspNet.Identity;
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Linq;
using System.Web;

namespace AspNetIdentity.Models
{
    public class TiKuUser : Microsoft.AspNet.Identity.IUser<Guid>
    {
        /// <summary>
        /// 用户编号
        /// </summary>
        public Guid Id
        {
            get;
            set;
        }

        /// <summary>
        /// 
        /// </summary>
        [DisplayName("登录名")]
        public string UserName
        {
            get;
            set;
        }

        /// <summary>
        /// 密码
        /// </summary>
        [DisplayName("密码")]
        public string Password { get; set; }

        /// <summary>
        /// 昵称
        /// </summary>
        [DisplayName("昵称")]
        public string Nick { get; set; }


    }
}
这样,就完成了用户的注册。接下来,就是用户认证的过程了。这时,你会发现,Microsoft.AspNet.Identity.Owin.SignInManager为我们提供了丰富的方法,来完成用户的认证。认证成功后,会向客户端发送加密的Cookie。这时,我们可通过HttpContext.Current.User对象,来获取认证信息。


登录代码如下:


/// <summary>
        /// 登陆
        /// </summary>
        /// <param name="user"></param>
        /// <returns></returns>
        [HttpPost]
        [AllowAnonymous]
        public async Task<ActionResult> Login(TiKuUser @user)
        {

            if (string.IsNullOrEmpty(@user.UserName)) { return View(); }
            if (string.IsNullOrEmpty(@user.Password)) { return View(); }

            //Context
            Microsoft.Owin.IOwinContext OwinContext = HttpContext.GetOwinContext();

            //实例化UserStore对象
            Models.TiKuUserStore userStore = new Models.TiKuUserStore();

            //UserManager
            TiKuUserManager UserManager = new TiKuUserManager(userStore);

            //signInManager
            TiKuSignInManager signInManager = new TiKuSignInManager(UserManager, AutherticationManager);


            //登录
            Microsoft.AspNet.Identity.Owin.SignInStatus SignInStatus = await signInManager.PasswordSignInAsync(@user.UserName,
                                                                                                               @user.Password,
                                                                                                               true,
                                                                                                               shouldLockout: false);

            //状态
            switch (SignInStatus)
            {
                //成功
                case Microsoft.AspNet.Identity.Owin.SignInStatus.Success:

                    //标示
                    //System.Security.Claims.ClaimsIdentity identity = UserManager.CreateIdentity(user, DefaultAuthenticationTypes.ApplicationCookie);

                    //授权登陆
                    //AutherticationManager.SignIn(new Microsoft.Owin.Security.AuthenticationProperties { IsPersistent = true }, identity);
                    return RedirectToAction("index", "home");
                //锁定
                case Microsoft.AspNet.Identity.Owin.SignInStatus.LockedOut:
                    Response.Write("LockedOut!");
                    break;
                //要求验证
                case Microsoft.AspNet.Identity.Owin.SignInStatus.RequiresVerification:
                    Response.Write("RequiresVerification!");
                    break;
                //登录失败
                case Microsoft.AspNet.Identity.Owin.SignInStatus.Failure:
                    Response.Write("Failure!");
                    break;

            }

            return View(@user);
        }
    }
我们来看看实际效果吧。


这里,做了个简单的登录表单。登录成功后,会发现,客户端多了一长串Cookie。

这是加密后的用户登录凭据。这样,用户认证成功后,就可以访问到[Authorize]的Action了。

    我们在创建MVC项目的时候,有两个文件需要注意下,就是根目录下的Startup.cs和App_Start目录下的Startup.Auth.cs两个类,它们以分布类的形式,存放于解决方案不同目录中。我们看看Startup都做了那些工作。

        }
    }

    {
        // 有关配置身份验证的详细信息,请访问 http://go.microsoft.com/fwlink/?LinkId=301864
        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
            app.UseCookieAuthentication(new CookieAuthenticationOptions
            {
                AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
                LoginPath = new PathString("/Account/Login"),
                CookieHttpOnly = true,
                CookieName = "__KaoLaTicketSid"
            });

            // Use a cookie to temporarily store information about a user logging in with a third party login provider
            app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);

        }
    }
}

有了这个两个启动类,应用程序在启动的时候,就会触发Configuration方法,完成OWIN的配置工作。

 如果你有更多疑问,不妨说出来,我们共同探讨。

在口令验证过程中,SignInManager的PasswordSignInAsync里面你直接调用了基类函数,然后调用UserManager中的OldSystemPasswordHasher中的VerifyHashedPassword完成检验,可VerifyHashedPassword返回的是PasswordVerificationResult类型,而PasswordSignInAsync返回的则是SignInStatus类型,两者是如何转换的?如果VerifyHashedPassword返回PasswordVerificationResult.SuccessRehashNeeded系统就会异常!不知道如何处理
