I have some problem with authorization:
The AuthorizeWebForm
codes work when loading the page, I am not in the admin group so I don't have the access, which is great. But when I refresh the page, I have access to the page, and the code AuthorizeWebFormAttribute
doesn't run when refresh. Any solution to this?
[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, Inherited = true, AllowMultiple = true)]
public class AuthorizeWebFormAttribute : System.Attribute
{
public AuthorizeWebFormAttribute(string Roles = null)
{
IPrincipal user = HttpContext.Current.User;
if (user.Identity.IsAuthenticated)
{
if (Roles == null)
return;
if (user.IsInRole("admin"))
return;
string[] roleArray = Roles.Split(',');
foreach (var role in roleArray)
{
if (user.IsInRole(role))
return;
}
}
HttpContext.Current.Server.TransferRequest("~/Unauthorized", false);
}
}
namespace Crew
{
[AuthorizeWebForm("admin")]
protected void Page_Load(object sender, EventArgs e)
{
if (string.IsNullOrEmpty(Session["EmpNo_User"].ToString()))
{
Response.Redirect("~/ErrorPage.aspx?CustError=This page expired. Please close the broswer and open again.");
}
Page.MaintainScrollPositionOnPostBack = true;
}
}
Thank you very much!
You are reinventing the wheel here. There's a perfectly good AuthorizeAttribute
class you can use: https://docs.microsoft.com/en-us/dotnet/api/system.web.mvc.authorizeattribute?view=aspnet-mvc-5.2
Also take a look at https://docs.microsoft.com/en-us/aspnet/web-forms/overview/older-versions-security/roles/role-based-authorization-cs for role-based security in general.
