【问题描述】:
我正在尝试使用模拟测试同时与不同用户连接的 ASP.NET MVC4 Web 应用程序。因此,测试的想法是执行驱动程序的多个实例,每个实例都有不同的模拟用户。这在概念上听起来很简单......
但是,如果在使用与当前用户不同的用户调用 LogonUser 之后运行 IEDriverServer,则在启动时会显示应用程序错误对话框。这是EventLog中注册的信息:
Faulting application name: IEDriverServer.exe, version: 2.44.0.0, time stamp: 0x54496690
Faulting module name: IED7543.tmp, version: 0.0.0.0, time stamp: 0x5449668c
Exception code: 0xc0000005
Fault offset: 0x000000000009d609
Faulting process id: 0x760
Faulting application start time: 0x01d00e3d12f93475
Faulting application path: ...\bin\IEDriverServer.exe
Faulting module path: C:\Users\user\AppData\Local\Temp\IED7543.tmp
Report Id: 5383a54d-7a30-11e4-b39c-000c29b46927
这是我用于模拟的代码。它基于我找到的所有示例,所以我并不感到意外......我们还尝试使用 SimpleImpersonation 包,结果相同:
public class ImpersonationHelper
{
public enum LogonType
{
Interactive = 2,
Network = 3,
Batch = 4,
Service = 5,
Unlock = 7,
Cleartext = 8, // Win2K or higher
NewCredentials = 9 // Win2K or higher
};
public enum LogonProvider
{
Default = 0,
Winnt35 = 1,
Winnt40 = 2,
Winnt50 = 3
};
public enum ImpersonationLevel
{
SecurityAnonymous = 0,
SecurityIdentification = 1,
SecurityImpersonation = 2,
SecurityDelegation = 3
}
[DllImport("advapi32.dll", SetLastError = true, CharSet = CharSet.Unicode)]
public static extern bool LogonUser(String lpszUsername, String lpszDomain, String lpszPassword,
int dwLogonType, int dwLogonProvider, out IntPtr phToken);
[DllImport("kernel32.dll")]
[ReliabilityContract(Consistency.WillNotCorruptState, Cer.Success)]
[SuppressUnmanagedCodeSecurity]
[return: MarshalAs(UnmanagedType.Bool)]
private static extern bool CloseHandle(IntPtr handle);
[DllImport("advapi32.dll", CharSet = CharSet.Auto, SetLastError = true)]
public static extern int DuplicateToken(IntPtr hToken,
int impersonationLevel, ref IntPtr hNewToken);
public sealed class Impersonator : IDisposable
{
public string Domain { get; private set; }
public string User { get; private set; }
public string Password { get; private set; }
public LogonType Type { get; private set; }
public LogonProvider Provider { get; private set; }
private WindowsImpersonationContext _context;
private IntPtr _token;
[PermissionSetAttribute(SecurityAction.Demand, Name = "FullTrust")]
public Impersonator(string domain, string user, string password,
LogonType type = LogonType.Interactive,
LogonProvider provider = LogonProvider.Default)
{
Domain = domain;
User = user;
Password = password;
Type = type;
Provider = provider;
_token = IntPtr.Zero;
Logon();
}
public void Dispose()
{
Undo();
}
private void Logon()
{
try
{
if (!LogonUser(User, Domain, Password, (int)Type, (int)Provider, out _token))
{
int ret = Marshal.GetLastWin32Error();
throw new Exception(String.Format("LogonUser failed with error code : {0}", ret));
}
_context = WindowsIdentity.Impersonate(_token);
}
catch (Exception exception)
{
var message = exception.Message;
Undo();
}
}
private void Undo()
{
try
{
if (_token != IntPtr.Zero)
{
CloseHandle(_token);
_token = IntPtr.Zero; // Clean _token so Undo() could be called several times
}
if (_context != null)
{
_context.Undo();
_context = null; // Clean _context so Undo() could be called several times
}
}
catch (Exception exception)
{
var message = exception.Message;
// Releasing resources failed...
}
}
}
}
引发异常的代码是:
using (new ImpersonationHelper.Impersonator("WIN-NKLTTMMUEPD", "tester", "tester"))
{
using (IWebDriver driver = new InternetExplorerDriver())
{
driver.Url = _appAddress;
return null;
}
}
有人知道如何防止出现此错误吗?非常感谢您。
