WindowsImpersonationContext &在 ASP.Core 中找不到 Impersonate()

问题描述

我在 .NET Framework 4.0 程序集中有以下内容:

I had the following in a .NET Framework 4.0 assembly:

var newId = new WindowsIdentity(duplicateTokenHandle);
WindowsImpersonationContext newId = ImpersonatedIdentity.Impersonate();

我正在将它移植到 ASP.Core，但是没有找到 WindowsImpersonationContext 和 WindowsIdentity.Impersonate().

I'm porting it to ASP.Core, but WindowsImpersonationContext and WindowsIdentity.Impersonate() aren't found.

我尝试添加以下内容:

类型	版本
System.Security.Claims	4.3.0
System.Security.Principal	4.3.0
System.Security.Principal.Windows	4.3.0

如何在 ASP.Core 中执行模拟?

How do I perform impersonation in ASP.Core?

更新

看起来它在 .NET Core 或 .NET Standard 中不受支持 - 是否有解决方法，或者我是否必须辞职以针对框架?

It looks like it's not supported in .NET Core or .NET Standard - is there a work-around or do I have to resign to targeting the framework?

推荐答案

Necromancing.
像这样:

Necromancing.
Like this:

using System.Security.Principal;


namespace regeditor
{


    public class WindowsLogin : System.IDisposable
    {
        protected const int LOGON32_PROVIDER_DEFAULT = 0;
        protected const int LOGON32_LOGON_INTERACTIVE = 2;

        public WindowsIdentity Identity = null;
        private System.IntPtr m_accessToken;


        [System.Runtime.InteropServices.DllImport("advapi32.dll", SetLastError = true)]
        private static extern bool LogonUser(string lpszUsername, string lpszDomain,
        string lpszPassword, int dwLogonType, int dwLogonProvider, ref System.IntPtr phToken);

        [System.Runtime.InteropServices.DllImport("kernel32.dll", CharSet = System.Runtime.InteropServices.CharSet.Auto)]
        private extern static bool CloseHandle(System.IntPtr handle);


        // AccessToken ==> this.Identity.AccessToken
        //public Microsoft.Win32.SafeHandles.SafeAccessTokenHandle AT
        //{
        //    get
        //    {
        //        var at = new Microsoft.Win32.SafeHandles.SafeAccessTokenHandle(this.m_accessToken);
        //        return at;
        //    }
        //}


        public WindowsLogin()
        {
            this.Identity = WindowsIdentity.GetCurrent();
        }


        public WindowsLogin(string username, string domain, string password)
        {
            Login(username, domain, password);
        }


        public void Login(string username, string domain, string password)
        {
            if (this.Identity != null)
            {
                this.Identity.Dispose();
                this.Identity = null;
            }


            try
            {
                this.m_accessToken = new System.IntPtr(0);
                Logout();

                this.m_accessToken = System.IntPtr.Zero;
                bool logonSuccessfull = LogonUser(
                   username,
                   domain,
                   password,
                   LOGON32_LOGON_INTERACTIVE,
                   LOGON32_PROVIDER_DEFAULT,
                   ref this.m_accessToken);

                if (!logonSuccessfull)
                {
                    int error = System.Runtime.InteropServices.Marshal.GetLastWin32Error();
                    throw new System.ComponentModel.Win32Exception(error);
                }
                Identity = new WindowsIdentity(this.m_accessToken);
            }
            catch
            {
                throw;
            }

        } // End Sub Login


        public void Logout()
        {
            if (this.m_accessToken != System.IntPtr.Zero)
                CloseHandle(m_accessToken);

            this.m_accessToken = System.IntPtr.Zero;

            if (this.Identity != null)
            {
                this.Identity.Dispose();
                this.Identity = null;
            }

        } // End Sub Logout


        void System.IDisposable.Dispose()
        {
            Logout();
        } // End Sub Dispose


    } // End Class WindowsLogin


} // End Namespace

用法:

*// WindowsIdentity user = (WindowsIdentity)context.User.Identity;
// using (WindowsIdentity user = WindowsIdentity.GetCurrent())

using (WindowsLogin wi = new WindowsLogin("Administrator", System.Environment.MachineName, "TOP_SECRET"))
{
    #if NET461
    using (user.Impersonate())
    #else
    WindowsIdentity.RunImpersonated(wi.Identity.AccessToken, () =>
    #endif
    {
        WindowsIdentity useri = WindowsIdentity.GetCurrent();
        System.Console.WriteLine(useri.Name);
    }
    #if !NET461
    );
    #endif

}*
