Microsoft.AspNet.Identity.Core 包含 ASP.NET Identity 核心接口
Microsoft.AspNet.Identity.EntityFramework ASP.NET Identity 的实体框架提供程序
添加用户注册代码
var userStore = new UserStore<IdentityUser>();
var manager = new UserManager<IdentityUser>(userStore); var user = new IdentityUser() { UserName = ... };
IdentityResult result = manager.Create(user, ...); if (result.Succeeded)
{
}
else
{
}

- IUserStore，公布用户管理的基本 api
- IUserLoginStore，此接口将用户映射到 login 提供程序，例如 Google, Facebook, Twitter
- IUserClaimStore 保存声明。
- IUserRoleStore 此接口将用户映射到角色
- IdentityUser 实现在 ASP.NET Identity Core 中定义的 IUser 接口，IUser 接口表示用户。
- UserManager 公布向 UserStore 保存更改的 API。
- IdentityResult 在 ASP.NET Identity Core 中定义，表示操作结果。

安装 Owin 程序包
Microsoft.AspNet.Identity.Owin 包含一组 OWIN 扩展类，用于管理和配置 OWIN 身份验证中间件，这些类由 ASP.NET Identity.Core 程序包使用。
Microsoft.Owin.Host.SystemWeb 包含一个 OWIN 服务器，使基于 OWIN 的应用程序可在 IIS 集成管道内运行。
添加 OWIN 启动类和身份验证配置类
[assembly: OwinStartup(typeof(Startup))] public partial class Startup
{
public void Configuration(IAppBuilder app)
{
app.UseCookieAuthentication(new CookieAuthenticationOptions
{
AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
LoginPath = new PathString("/Account/Login"),
Provider = new CookieAuthenticationProvider
{
// 当用户登录时使应用程序可以验证安全戳。
// 这是一项安全功能，当你更改密码或者向帐户添加外部登录名时，将使用此功能。
OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<ApplicationUserManager, ApplicationUser>(
validateInterval: TimeSpan.FromMinutes(),
regenerateIdentity: (manager, user) => user.GenerateUserIdentityAsync(manager))
}
}); }
}
OwinStartupAttribute 用于配置启动类，默认情况下会调用名为 Configuration 的方法，也可通过 MethodName 指定不同的方法名。
修改用户注册代码
使用户在注册后自动登录
var userStore = new UserStore<IdentityUser>();
var manager = new UserManager<IdentityUser>(userStore); var user = new IdentityUser() { UserName = ... };
IdentityResult result = manager.Create(user, ...); if (result.Succeeded)
{
var authenticationManager = this.HttpContext.GetOwinContext().Authentication;
var userIdentity = manager.CreateIdentity(user, DefaultAuthenticationTypes.ApplicationCookie);
authenticationManager.SignIn(new AuthenticationProperties() { }, userIdentity);
}
else
{
}
ASP.NET Identity 和 OWIN Cookie Authentication 是基于声明的，因此需要为用户生成 ClaimsIdentity 对象。ClaimsIdentity 包含用户所有的声明信息，例如，用户属于哪些角色。可以在这里为用户添加更多声明。通过调用 AuthenticationManager.SignIn 方法使用户登录。IAuthenticationManager 接口在 OWIN 中定义。这段代码会产生一个 cookie，类似于 Forms 身份验证的 FormAuthentication.SetAuthCookie 方法。
添加登录代码
var userStore = new UserStore<IdentityUser>();
var userManager = new UserManager<IdentityUser>(userStore);
var user = userManager.Find(...); if (user != null)
{
var authenticationManager = this.HttpContext.GetOwinContext().Authentication;
var userIdentity = userManager.CreateIdentity(user, DefaultAuthenticationTypes.ApplicationCookie); authenticationManager.SignIn(new AuthenticationProperties() { IsPersistent = false }, userIdentity);
// 登录成功
}
else
{
// 登录失败
}
GetOwinContext 是一个扩展方法，在 Microsoft.Owin.Host.SystemWeb 程序集中定义，它返回 IOwinContext 对象，OwinContext 公布 IAuthenticationManager 属性，表示对本次请求可用的身份验证中间件。
添加注销代码
var authenticationManager = this.HttpContext.GetOwinContext().Authentication;
authenticationManager.SignOut();
