模拟ASP.NET声明身份到Windows身份

但现在我需要模拟当前的请求/线程,以便我可以访问不是声明感知的服务.我该怎么办？

我应该在Application_PostAuthenticate事件中获取一个WindowsImpersonationContext并将其保存在HttpContext.Items中,然后在Application_EndRequest中调用Undo方法吗？

或者还有其他首选方式吗？

更新：因为我没有得到任何关于模仿的首选方式的提示我尝试了自己的建议.我在global.asax.cs中创建了这段代码：

private static readonly string WICKey = typeof(System.Security.Principal.WindowsImpersonationContext).AssemblyQualifiedName;

    protected void Application_PostAuthenticateRequest()
    {
        var wid = User.Identity as System.Security.Principal.WindowsIdentity;
        if (wid != null)
        {
            HttpContext.Current.Trace.Write("PostAuthenticateRequest PreImpersonate: " + System.Security.Principal.WindowsIdentity.GetCurrent().Name);
            HttpContext.Current.Items[WICKey] = wid.Impersonate();
            HttpContext.Current.Trace.Write("PostAuthenticateRequest PostImpersonate: " + System.Security.Principal.WindowsIdentity.GetCurrent().Name);
        }
    }

    protected void Application_EndRequest()
    {
        var wic = HttpContext.Current.Items[WICKey] as System.Security.Principal.WindowsImpersonationContext;
        if (wic != null)
        {
            HttpContext.Current.Trace.Write("EndRequest PreUndoImpersonate: " + System.Security.Principal.WindowsIdentity.GetCurrent().Name);
            wic.Undo();
            HttpContext.Current.Trace.Write("EndRequest PostUndoImpersonate: " + System.Security.Principal.WindowsIdentity.GetCurrent().Name);
        }
    }

当我查看跟踪日志时,我看到了这一点

PostAuthenticateRequest PreImpersonate: NT AUTHORITYNETWORK SERVICE   
PostAuthenticateRequest PostImpersonate: MyDomainCorrectUser
Home: NT AUTHORITYNETWORK SERVICE
EndRequest PreUndoImpersonate: NT AUTHORITYNETWORK SERVICE
EndRequest PostUndoImpersonate: NT AUTHORITYNETWORK SERVICE

因此,在第二行中,您可以看到线程被正确模拟.但是在下一行中你会看到模仿已经丢失. (第三行来自控制器).

当我使用以下代码在本地模拟时,它工作正常：

var wid = User.Identity as System.Security.Principal.WindowsIdentity;
        if (wid != null)
        {
            using (var ctx = wid.Impersonate())
            {
                //Do something
            }
        }

但我想模仿整个请求的生命周期.
我该怎么办？
