ASP.NET：对VMWare上的域进行模拟

问题描述

我需要在VMWare机器上运行的ASP.NET应用程序中将自己模拟为域用户。由于VMWare机器本身不在域中，ASP.NET无法解析用户令牌（在web.config中指定）。有没有办法这样做？

I need to impersonate myself as a domain user in a ASP.NET application running on VMWare machine. Since the VMWare machine is not itself in the domain, ASP.NET is unable to resolve the user token (specified in web.config). Is there a way to do that?

提前感谢

我使用这个我一直写的这个类，它的作用就像一个魅力！

I use this class I wrote all the time and it works like a charm!

using System;
using System.Security.Principal;

/// <summary>
/// Changes the security context the application runs under.
/// </summary>
public class ImpersonateHelper : IDisposable
{
    [System.Runtime.InteropServices.DllImport("Kernel32")]
    private extern static Boolean CloseHandle(IntPtr handle);

    private IntPtr _token = IntPtr.Zero;
    private WindowsImpersonationContext _impersonatedUser = null;

    public IntPtr Token
    {
        get { return _token; }
        set { _token = value; }
    }

    public ImpersonateHelper(IntPtr token)
    {
        _token = token;
    }

    /// <summary>
    /// Switch the user to that set by the Token property
    /// </summary>
    public void Impersonate()
    {
        if (_token == IntPtr.Zero)
            _token = WindowsIdentity.GetCurrent().Token;

        _impersonatedUser = WindowsIdentity.Impersonate(_token);
    }

    /// <summary>
    /// Revert to the identity (user) before Impersonate() was called
    /// </summary>
    public void Undo()
    {
        if (_impersonatedUser != null)
            _impersonatedUser.Undo();
    }

    #region IDisposable Members
    private bool _isDisposed;

    public void Dispose()
    {
        Dispose(true);
        GC.SuppressFinalize(this);
    }

    protected virtual void Dispose(bool disposing)
    {
        if (!_isDisposed)
        {
            if (disposing)
            {
                if (_impersonatedUser != null)
                    _impersonatedUser.Dispose();

            }
            CloseHandle(_token);
            _token = IntPtr.Zero;
        }
        _isDisposed = true;
    }

    ~ImpersonateHelper()
    {
        Dispose(false);
    }
    #endregion
}

然后你从客户端类作为：

Then you call it from the client class as:

//Run task as the impersonated user and not as NETWORKSERVICE or ASPNET (in IIS5)
try{
   impersonate.Impersonate();
   //Do work that needs to run as domain user here...
}
finally
{
            //Revert impersonation to NETWORKSERVICE or ASPNET
            if (impersonate != null)
            {
                impersonate.Undo();
                impersonate.Dispose();
            }
}

祝你好运！
