【源码】继承pagebase 权限判断
public partial class TopFrame : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Func.GetAllObjectList();
(new Func()).GetRolePermission();
}
}
PageBase的全局调用
override protected void OnInit(EventArgs e)
{
InitializeComponent();
Func.CheckThisPage(); //步骤3： 每次页面载入调用检查权限
base.OnInit(e);
}
全局检查session
public void CheckUserPurview()
{
if (System.Web.HttpContext.Current.Session["UserID"] == null)
{
this.RegisterStartupScript("relogin", "<script language=javascript>window.top.location.href='index.aspx'</script>");
}
}
鉴权逐出
public void DenyAccess()
{
System.Web.HttpContext.Current.Response.Write("<center><br><br><br><br><br><br>" + "您没有权限进入" + "<br><br>3 秒钟后返回......</center>");
System.Web.HttpContext.Current.Response.Write("<meta http-equiv=\"refresh\" content=\"3;URL=" + "Sysmain.aspx" + "\" />");
System.Web.HttpContext.Current.Response.Write("<body bgcolor='white'>");
System.Web.HttpContext.Current.Response.End();
}
框架顶页面 登录后调用一次，驻留
public partial class TopFrame : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Func.GetAllObjectList();
(new Func()).GetRolePermission();
}
}
