针对 IPrincipal 的扩展： public static bool ClaimExists(this IPrincipal principal, string claimType) { var ci = principal as ClaimsPrincipal; if (ci == null) { return false; } var claim = ci.Claims.FirstOrDefault(x => x.Type == claimType); return

Before doing this tutorial you should first complete Create a secure ASP.NET MVC 5 web app with log in, email confirmation and password reset. This tutorial contains more details and will show you how to set up email for local account confirmation and allow users to reset their forgotten password in

我们知道，在Asp.Net Identity体系中，实体数据模型均为基于Entityframework执行操作的。本文就以此来分析微软对EF实际应用中的封装方案，以对比市面上大部分对EF封装，探讨EF使用的架构方案。RoleStore Class:public class RoleStore<trole , TKey, TUserRole> : IQueryableRoleStore</trole><trole , TKey>, IRoleStore</trole><trole , TKey>, IDisposable

在MVC5项目中可以方便的添加第三方开放平台的登陆。本文方法介绍了在用户通过第三方登陆后，存储其AccessToken，以便下次直接使用此AccessToken值获取相关信息的方式。开启第三方登陆app.UseFacebookAuthentication( appId: "", appSecret: "");经过这一步，用户已经可以顺利登陆了，但还可以把用户登陆后获取到的accessToken添加到identity claim中，以便下次取用。添加 AccessToken 到 identity claimpublic partial class Startup{ // For

方法如下：ApplicationDbContext dbContext = context.OwinContext.Get<ApplicationDbContext>();ApplicationUserManager userManager = context.OwinContext.GetUserManager<ApplicationUserManager>(); 

因为在Identity数据库中初始化用户数据，需要设计密码的加密转换，所以尽管与其它数据初始化相同都是发生在EF数据迁移配置的Seed() 方法中，但因此稍有不同。方法1：protected override void Seed(SimpleOAuthSample.Models.OAuthDbContext context){ context.Clients.AddOrUpdate( client => client.Name, new Client { Id = "42ff5dad3c274c97a3a7c3d44b

在MVC5 OWin 中间件对 OAuth 提供了比较全面的支持，其中就包括通过客户端 ClientId 与 SecretKey 进行验证的 client credentials 验证方式。与常见的开放平台登陆机制一致， client credentials验证是作为对服务开放整体服务授权的一种策略。客户端通过 ClientId 与 SecretKey 获得 accessToken 。client credentials 请求实例：GET https://mydomain.com/token HTTP/1.1Content-type:application/x-www-form-urlenco

For the last couple of weeks, I’ve been involved with a project which includes several sub-projects that will need to communicate with each other, and with a credit card processor (Authorize.net).  In addition, other applications will call into this one to handle payment processing business logic.
