编辑:
我在 windows server 2008 上使用我的应用程序,一些文件需要为我的应用程序读取/写入权限,但我有这样的错误,所以我需要解决这个问题,我的来源是:
public override void Process(NPHandler client)
{
var fileName = Message.fileName;
var fileData = Message.fileData;
var npid = (long)Message.npid;
var fsFile = StorageUtils.GetFilename(fileName, npid);
_client = client;
_fileName = fileName;
_npid = npid;
if (!client.Authenticated)
{
ReplyWithError(1);
return;
}
if (client.NPID != (long)npid)
{
ReplyWithError(1);
return;
}
if (!Directory.Exists(Path.GetDirectoryName(fsFile)))
{
Directory.CreateDirectory(Path.GetDirectoryName(fsFile));
}
// are we allowed to write this type of file?
if (!_fileHooks.ContainsKey(fileName))
{
ReplyWithError(1);
return;
}
string backupFile = null;
int result = _fileHooks[fileName](fileData, fsFile, out backupFile);
if (result > 0)
{
ReplyWithError(result);
return;
}
Log.Info(string.Format("Got a request for writing {0} bytes to file {1} for user {2}.", fileData.Length, fileName, npid.ToString("X16")));
try
{
var stream = File.Open(fsFile, FileMode.Create, FileAccess.Write);
stream.BeginWrite(fileData, 0, fileData.Length, WriteCompleted, stream);
if (backupFile != null)
{
var backupStream = File.Open(backupFile, FileMode.Create, FileAccess.Write);
backupStream.BeginWrite(fileData, 0, fileData.Length, BackupWriteCompleted, backupStream);
}
}
catch (Exception ex)
{
Log.Error(ex.ToString());
ReplyWithError(2);
}
}
