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
}
}
}
