通过文件共享,用户身份验证通过网络复制文件

Question

我正在构建一个.net C#控制台程序,以将文件部署到Windows文件共享服务器(正在共享的文件夹).路径是::\\192.168.0.76\htdocs\public

在运行时我收到错误:

[09:35:29]: [Step 1/3] Unhandled Exception: System.UnauthorizedAccessException: Access to the path '\\192.168.0.76\htdocs\public' is denied.
[09:35:29]: [Step 1/3]    at DeployFileShare.Program.CopyDir(String source, String dest, String[] exclude, Boolean overwrite)
[09:35:29]: [Step 1/3]    at DeployFileShare.Program.Deploy(String num, String source)
[09:35:29]: [Step 1/3]    at DeployFileShare.Program.Main(String[] args)
[09:35:29]: [Step 1/3] Process exited with code -532459699

我想我需要对自己进行身份验证.我遇到过这个:

AppDomain.CurrentDomain.SetPrincipalPolicy(PrincipalPolicy.WindowsPrincipal);
WindowsIdentity idnt = new WindowsIdentity(username, password);
WindowsImpersonationContext context = idnt.Impersonate();

我也尝试过:

AppDomain.CreateDomain("192.168.0.76").SetPrincipalPolicy(PrincipalPolicy.WindowsPrincipal);
WindowsIdentity idnt = new WindowsIdentity("user", "pass");
WindowsImpersonationContext context = idnt.Impersonate();

我不知道如何使用它.当我运行应用程序时,我得到:

C:\Users\Administrator>DeployFileShare 1 R:\BuildOutput\_PublishedWebsites\Web 2
1
Deploy Started Web, version 21
-- Deploy Prepared
-- Deploying to 1

Unhandled Exception: System.Security.SecurityException: There are currently no l
ogon servers available to service the logon request.

   at System.Security.Principal.WindowsIdentity.KerbS4ULogon(String upn)
   at System.Security.Principal.WindowsIdentity..ctor(String sUserPrincipalName,
 String type)

   at DeployFileShare.Program.Deploy(String num, String source)
   at DeployFileShare.Program.Main(String[] args)
The Zone of the assembly that failed was:
MyComputer

这是基本代码:

static void Main()
{
Copy();
}
static void Copy()
{
AppDomain.CreateDomain(GetServerInfo(server, "server")).SetPrincipalPolicy(PrincipalPolicy.WindowsPrincipal);
            WindowsIdentity idnt = new WindowsIdentity(GetServerInfo(server, "user"), GetServerInfo(server, "pass"));
            WindowsImpersonationContext context = idnt.Impersonate();
string source = "C:\\someDir";
string dest = "\\192.168.0.76\shareFolder"
string[] sourceFiles = Directory.GetFiles(source, "*", SearchOption.AllDirectories);
            foreach (string file in sourceFiles)
            {
                string local = file.Replace(source, "");
                if (exclude.Contains(local))
                    continue;
                if (!Directory.Exists(Path.GetDirectoryName(dest + "\\" + local)))
                    Directory.CreateDirectory(Path.GetDirectoryName(dest + "\\" + local));
                File.Copy(file, dest + "\\" + local, overwrite);
                Console.WriteLine("-- -- [copied] {0} -> {1}", file, dest + "\\" + local);
            }
}

for循环中的代码复制系统工作,我已经在我的本地系统上测试过了.

如果有人知道我应该如何使用WindowsIdentity和WindowsIdentity来实现这一点,请赐教.我一直在环顾四周,窗口的文档没有多大帮助.

基本上我如何通过登录系统复制到共享的远程目录？

Answer 1

VB但很容易翻译成C#.在复制之前执行此操作:

Private Sub Open_Remote_Connection(ByVal strComputer As String, ByVal strUserName As String, ByVal strPassword As String)
    Dim ProcessStartInfo As New System.Diagnostics.ProcessStartInfo
    ProcessStartInfo.FileName = "net"
    ProcessStartInfo.Arguments = "use \\" & strComputer & "\c$ /USER:" & strUsername & " " & strPassword
    ProcessStartInfo.WindowStyle = ProcessWindowStyle.Hidden
    System.Diagnostics.Process.Start(ProcessStartInfo)
    System.Threading.Thread.Sleep(2000)
End Sub

如果要对远程计算机进行身份验证以移动文件,可以使用LogonUser函数和WindowsIdentity来模拟您的用户.

/// <summary>
/// Exécute une fonction en empruntant les credentials
/// </summary>
private T ApplyCredentials<T>(Func<T> func)
{
    IntPtr token;

    if (!LogonUser(
        _credentials.UserName,
        _credentials.Domain,
        _credentials.Password,
        LOGON32_LOGON_INTERACTIVE,
        LOGON32_PROVIDER_DEFAULT,
        out token))
    {
        Marshal.ThrowExceptionForHR(Marshal.GetHRForLastWin32Error());
    }

    try
    {
        // On doit être impersonifié seulement le temps d'ouvrir le handle.
        using (var identity = new WindowsIdentity(token))
        using (var context = identity.Impersonate())
        {
            return func();
        }
    }
    finally
    {
        CloseHandle(token);
    }
}

// ...

if (_credentials != null)
{
    return this.ApplyCredentials(() => File.Open(path, mode, access, share));
}

return File.Open(path, mode, access, share);
