asp.net程序开发，用户根据角色访问对应页面以及功能。
项目结构如下图：
根目录 Web.config 代码：
<?xml version="1.0" encoding="utf-8"?> <!-- 有关如何配置 ASP.NET 应用程序的详细消息，请访问 ?LinkId=169433 --> <configuration> <system.web> <compilation debug="true" targetFramework="4.0" /> <authentication mode="Forms"> <forms loginUrl="login.aspx"></forms> </authentication> <!--<authorization> <allow users="*"></allow> </authorization>--> </system.web> </configuration>
admin文件夹中 Web.config 代码：
<?xml version="1.0"?> <configuration> <system.web> <authorization> <allow roles="admin" /> <deny users="*"/> </authorization> </system.web> </configuration>
teacher文件夹中 Web.config 代码：
<?xml version="1.0"?> <configuration> <system.web> <authorization> <allow roles="teacher" /> <deny users="*"/> </authorization> </system.web> </configuration>
student文件夹中 Web.config 代码：
<?xml version="1.0"?> <configuration> <system.web> <authorization> <allow roles="student" /> <deny users="*"/> </authorization> </system.web> </configuration>
Login.aspx中登录成功后设置Cookie，设置Cookie代码：
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, "https://www.jb51.net/"); string hashTicket = FormsAuthentication.Encrypt(ticket); HttpCookie userCookie = new HttpCookie(FormsAuthentication.FormsCookieName, hashTicket); HttpContext.Current.Response.SetCookie(userCookie); }
Global.asax 中进行身份验证：
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 } } }
