 protected void SetLoginCookie(string username, string roles) { System.Web.Security.FormsAuthentication.SetAuthCookie(username, false); System.Web.Security.FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(1, username, DateTime.Now, DateTime.Now.AddDays(1), false, roles, "/"); string hashTicket = FormsAuthentication.Encrypt(ticket); HttpCookie userCookie = new HttpCookie(FormsAuthentication.FormsCookieName, hashTicket); HttpContext.Current.Response.SetCookie(userCookie); }

 protected void Application_AuthenticateRequest(object sender, EventArgs e) { HttpApplication app = (HttpApplication)sender; HttpContext ctx = app.Context; //获取本次Http请求的HttpContext对象 if (ctx.User != null) { if (ctx.Request.IsAuthenticated == true) //验证过的一般用户才能进行角色验证 { System.Web.Security.FormsIdentity fi = (System.Web.Security.FormsIdentity)ctx.User.Identity; System.Web.Security.FormsAuthenticationTicket ticket = fi.Ticket; //取得身份验证票 string userData = ticket.UserData;//从UserData中恢复role信息 string[] roles = userData.Split(','); //将角色数据转成字符串数组,得到相关的角色信息 ctx.User = new System.Security.Principal.GenericPrincipal(fi, roles); //这样当前用户就拥有角色信息了 } } }
