我需要在Delphi中获取域中Windows机器的完全限定域名。
我尝试使用LookupAccountSid
,但它仅提供NetBIOS域名,在我的情况下是"intranet",但我需要完整的"intranet.companyname.com"。
有什么想法吗?

尝试使用Windows API函数GetUserNameEx
。
const
NameUnknown = 0;
NameFullyQualifiedDN = 1;
NameSamCompatible = 2;
NameDisplay = 3;
NameUniqueId = 6;
NameCanonical = 7;
NameUserPrincipal = 8;
NameCanonicalEx = 9;
NameServicePrincipal = 10;
NameDnsDomain = 12;
function GetUserNameExString(ANameFormat: DWORD): string;
var
Buf: array[0..256] of Char;
BufSize: DWORD;
GetUserNameEx: function (NameFormat: DWORD; lpNameBuffer: LPSTR;
var nSize: ULONG): BOOL; stdcall;
begin
Result := '';
BufSize := SizeOf(Buf) div SizeOf(Buf[0]);
GetUserNameEx := GetProcAddress(GetModuleHandle('secur32.dll'), 'GetUserNameExA');
if Assigned(GetUserNameEx) then
if GetUserNameEx(ANameFormat, Buf, BufSize) then
Result := Buf;
end;
例如使用NameDnsDomain
格式,如果您已登录到"www.mydomain.com"域,将会得到www.mydomain.com\user_name
。
由于我现在已经根据自己的需要在我们的应用程序中实现了这一点,@iPath的评论是正确的。最好使用GetComputerNameEx
,并为自己的需求指定一个COMPUTER_NAME_FORMAT
。
Delphi实现代码如下(Unicode版本):
interface
...
type
COMPUTER_NAME_FORMAT = (
ComputerNameNetBIOS,
ComputerNameDnsHostname,
ComputerNameDnsDomain,
ComputerNameDnsFullyQualified,
ComputerNamePhysicalNetBIOS,
ComputerNamePhysicalDnsHostname,
ComputerNamePhysicalDnsDomain,
ComputerNamePhysicalDnsFullyQualified,
ComputerNameMax);
function GetComputerNameExString(ANameFormat: COMPUTER_NAME_FORMAT): WideString;
implementation
...
function GetComputerNameExW(NameType: COMPUTER_NAME_FORMAT; lpBuffer: LPWSTR;
var nSize: DWORD): BOOL; stdcall; external kernel32 name 'GetComputerNameExW';
function GetComputerNameExString(ANameFormat: COMPUTER_NAME_FORMAT): WideString;
var
nSize: DWORD;
begin
nSize := 1024;
SetLength(Result, nSize);
if GetComputerNameExW(ANameFormat, PWideChar(Result), nSize) then
SetLength(Result, nSize)
else
Result := '';
end;
我尝试了以上所有方法,但都没有成功。最终,我只好获取环境变量来解决问题。
uses jclSysInfo;
function GetDomain:string;
begin
result:=GetEnvironmentVariable('USERDNSDOMAIN');
end;
NetGetJoinInformation
应该可以正常工作。

NetGetJoinInformation := TNetGetJoinInformationFunction(GetProcAddress(NetApi, 'NetGetJoinInformation'));
NetWkstaGetInfo := TNetWkstaGetInfoFunction( GetProcAddress(NetApi, 'NetWkstaGetInfo'));
if @NetApiBufferFree <> nil then
begin
if @NetSetupJoinStatus <> nil then
begin
if NetGetJoinInformation(nil, NameBuffer, NetSetupJoinStatus) = NERR_SUCCESS then
begin
if NetSetupJoinStatus = NetSetupDomainName then
begin

end;
NetApiBufferFree(NameBuffer);
end;

end;
FreeLibrary(NetApi);

NetGetJoinInformation
获取一个简单的域名。 - Ondrej Kelle.companyname.com
结尾,那么这是正确的。在这种情况下,对IP地址进行反向DNS查找可能会得到FQDN,这也可能是OP想要的。 - Jens MühlenhoffPDOMAIN_CONTROLLER_INFOW pdomInfo ;
auto result1 = ::DsGetDcNameW(nullptr, nullptr, nullptr, nullptr, DS_DIRECTORY_SERVICE_PREFERRED | DS_RETURN_DNS_NAME, &pdomInfo);
if (result1 == ERROR_SUCCESS) {
auto retVal = SysAllocString(pdomInfo->DomainName);
::NetApiBufferFree(pdomInfo);
}
DomainA
帐户或DomainB
帐户登录到计算机上。当您使用GetUserNameEx
时,您将获得用户所在域的名称(如果有的话),这可能与计算机加入的域不同。您可以调用NetGetJoinInformation
来获取计算机加入的域/工作组/无的名称,但它返回 NetBIOS 域名。 - Ian Boyd
