我在授权方面遇到了一些问题:

AuthorizeWebForm代码在加载页面时有效,我不在admin组中,所以我没有访问权限,这很好。但是刷新页面时,我可以访问页面,刷新时代码AuthorizeWebFormAttribute不会运行。有什么解决办法吗?

 [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;
    }

}

非常感谢您!

您正在这里重新发明轮子。您可以使用一个非常好的Object { "key": "PastHireDetails", "params": undefined, "routeName": "PastHireDetails", } 类:https://docs.microsoft.com/en-us/dotnet/api/system.web.mvc.authorizeattribute?view=aspnet-mvc-5.2

另外,请参阅https://docs.microsoft.com/en-us/aspnet/web-forms/overview/older-versions-security/roles/role-based-authorization-cs,了解基于角色的安全性。
