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 http://go.microsoft.com/fwlink/?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, "/");
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 }
}
}
