UE4获取硬件信息

前言

本文记录UE4获取硬件信息和地址等常用方法

Mac地址

GetMacAddressString()方法已经在4.15版本后被彻底废弃, 所以UE目前(4.26)版本无法获取Mac地址

我们之前UE4获取第三方库文章中有用到使用自己用原生cpp获取到mac地址, 然后导出成动态或者静态库到UE4再封装成插件的形式来获取mac地址, 此方法也是目前比较快捷的一个方法

下面贴DLL/Lib的代码

//.h
#pragma once


#define DLL_EXPORT __declspec(dllexport)	//shortens __declspec(dllexport) to DLL_EXPORT

#ifdef __cplusplus		//if C++ is used convert it to C to prevent C++'s name mangling of method names
extern "C"
{
#endif
	int DLL_EXPORT GetMac(char * mac);
#ifdef __cplusplus
}
#endif

//cpp
#pragma once

#include "string.h"
#include "ThirdPartyDLL.h"


#include <windows.h>
#include <wincon.h>
#include <stdlib.h>
#include <stdio.h>
#include <time.h>
#include <Nb30.h>
#pragma comment(lib,"netapi32.lib")

int  GetMac(char * mac)
{
	NCB ncb;
	typedef struct _ASTAT_
	{
		ADAPTER_STATUS   adapt;
		NAME_BUFFER   NameBuff[30];
	}ASTAT, *PASTAT;

	ASTAT Adapter;

	typedef struct _LANA_ENUM
	{
		UCHAR   length;
		UCHAR   lana[MAX_LANA];
	}LANA_ENUM;

	LANA_ENUM lana_enum;
	UCHAR uRetCode;
	memset(&ncb, 0, sizeof(ncb));
	memset(&lana_enum, 0, sizeof(lana_enum));
	ncb.ncb_command = NCBENUM;
	ncb.ncb_buffer = (unsigned char *)&lana_enum;
	ncb.ncb_length = sizeof(LANA_ENUM);
	uRetCode = Netbios(&ncb);

	if (uRetCode != NRC_GOODRET)
		return uRetCode;

	for (int lana = 0; lana < lana_enum.length; lana++)
	{
		ncb.ncb_command = NCBRESET;
		ncb.ncb_lana_num = lana_enum.lana[lana];
		uRetCode = Netbios(&ncb);
		if (uRetCode == NRC_GOODRET)
			break;
	}

	if (uRetCode != NRC_GOODRET)
		return uRetCode;

	memset(&ncb, 0, sizeof(ncb));
	ncb.ncb_command = NCBASTAT;
	ncb.ncb_lana_num = lana_enum.lana[0];
	strcpy((char*)ncb.ncb_callname, "*");
	ncb.ncb_buffer = (unsigned char *)&Adapter;
	ncb.ncb_length = sizeof(Adapter);
	uRetCode = Netbios(&ncb);

	if (uRetCode != NRC_GOODRET)
		return uRetCode;

	sprintf(mac, "%02X-%02X-%02X-%02X-%02X-%02X",
		Adapter.adapt.adapter_address[0],
		Adapter.adapt.adapter_address[1],
		Adapter.adapt.adapter_address[2],
		Adapter.adapt.adapter_address[3],
		Adapter.adapt.adapter_address[4],
		Adapter.adapt.adapter_address[5]);

	return 0;
}

CPU信息

最常用的方法是获取CPU的品牌信息, 即用如下方法即可获取

Brand = FPlatformMisc::GetCPUBrand();

对比cmd中的信息

另外UE中还封装了其他一些CPU信息, 比如供应商等, 分别可以用如下方法去获取

	 Chipset = FPlatformMisc::GetCPUChipset();
	 Info = FPlatformMisc::GetCPUInfo();
	 Vendor = FPlatformMisc::GetCPUVendor();

GPU信息

GPU信息相比就多一些, 通过两个方法来获取

Brand = FPlatformMisc::GetPrimaryGPUBrand();//获取品牌信息,我这边获取的就是NVIDIA
//通过品牌信息获取其他设备信息,如供应商,驱动版本等
FGPUDriverInfo info = FPlatformMisc::GetGPUDriverInfo(Brand);
ProviderName = info.ProviderName;
VendorID = info.VendorId;
InternalDriverVersion = info.InternalDriverVersion;
UserDriverVersion = info.UserDriverVersion;
DriverDate = info.DriverDate;
RHIName = info.RHIName;

统统打印出来是如下

IP地址

需要包含库Sockets

#include "SocketSubsystem.h"

FString UFlib_DeviceInfo::GetIpAddress(bool bHasPort /*= true*/)
{
	FString IpAddr("NONE");

	bool canBind = false;
	`TSharedRef<FInternetAddr>`LocalIp = ISocketSubsystem::Get(PLATFORM_SOCKETSUBSYSTEM)->GetLocalHostAddr(*GLog, canBind);

	if (LocalIp->IsValid())
	{
		IpAddr = LocalIp->ToString(bHasPort); 
	}

	return IpAddr;
}
