我需要创建一个命名管道,用于客户端和服务器之间的通信(在同一主机中),这里是代码:
WCHAR wszPipeName[MAX_FILE_LENGTH];
swprintf_s(wszPipeName, MAX_FILE_LENGTH, L"\\\\.\\pipe\\TEST%d", uniqueID);
pipe = CreateNamedPipe(
wszPipeName, // name of the pipe
PIPE_ACCESS_DUPLEX,
PIPE_TYPE_MESSAGE | PIPE_READMODE_MESSAGE | PIPE_NOWAIT,
1,
MAX_MSG_SIZE,
MAX_MSG_SIZE , //inbound buffer
MAX_READ_DATA_TIMEOUT,
NULL // use default security attributes
);
处理程序返回总是INVALID_HANDLE_VAULE,错误是ERROR_ACCESS_DENIED。
这里有什么不对吗?它在Windows 7/8上运行。

这是Python代码,但这将为本地用户设置安全描述符,并拒绝远程用户:
dacl = ACL()
# Deny NT AUTHORITY\NETWORK SID
sid = CreateWellKnownSid(WinNetworkSid)
dacl.AddAccessDeniedAce(ACL_REVISION, GENERIC_ALL, sid)
# Allow current user SID
token = OpenProcessToken(GetCurrentProcess(), TOKEN_QUERY)
sid = GetTokenInformation(token, TokenUser)[0]
dacl.AddAccessAllowedAce(ACL_REVISION, GENERIC_READ | GENERIC_WRITE, sid)
security_descriptor = SECURITY_DESCRIPTOR()
security_descriptor.SetSecurityDescriptorDacl(True, dacl, False)
security_attributes = SECURITY_ATTRIBUTES()
security_attributes.SECURITY_DESCRIPTOR = security_descriptor
pipe = CreateNamedPipe(
<your other params here>
security_attributes
)
