c++ windows 获取mac地址-阿里云开发者社区

Windows平台下用C++代码取得机器的 MAC地址并不是一件简单直接的事情。到目前为止，作者尚未发现有任何一个通用的100%的适用于所有Windows平台的方法可以稳定的取得MAC地址。而有些应用（比如 MMORPG）则需要稳定的得到机器的MAC地址，解决方案往往是通过多种方法依次使用来提高成功率。

以下方法只会返回多网卡的第一个MAC地址。

网上有很多文章和源码来解决该问题，大多不全或有问题。本篇所有方法均经过整理调试，可直接使用。

作者也不喜欢满篇帖代码，本篇贴代码是方便直接使用，请读者谅解。

下面奉上几种常用的方法：

方法一：通过NetBIOS

[ Netbios is not supported on Windows Vista, Windows Server 2008, and subsequent versions of the operating system]

#include <windows.h>

#pragma comment(lib, "Netapi32.lib")

namespace

{

bool GetAdapterInfo(int adapterNum, std::string& macOUT)

{

NCB Ncb;

memset(&Ncb, 0, sizeof(Ncb));

Ncb.ncb_command = NCBRESET; // 重置网卡，以便我们可以查询

Ncb.ncb_lana_num = adapterNum;

if ( Netbios(&Ncb) != NRC_GOODRET)

return false;

// 准备取得接口卡的状态块

memset(&Ncb, sizeof(Ncb), 0);

Ncb.ncb_command = NCBASTAT;

Ncb.ncb_lana_num = adapterNum;

strcpy((char *) Ncb.ncb_callname, "*");

struct ASTAT

{

ADAPTER_STATUS adapt;

NAME_BUFFER nameBuff[30];

}adapter;

memset(&adapter,sizeof(adapter), 0);

Ncb.ncb_buffer = (unsigned char *)&adapter;

Ncb.ncb_length = sizeof(adapter);

if ( Netbios(&Ncb) != 0)

return false;

char acMAC[32];

sprintf(acMAC, "%02X-%02X-%02X-%02X-%02X-%02X",

int (adapter.adapt.adapter_address[0]),

int (adapter.adapt.adapter_address[1]),

int (adapter.adapt.adapter_address[2]),

int (adapter.adapt.adapter_address[3]),

int (adapter.adapt.adapter_address[4]),

int (adapter.adapt.adapter_address[5]));

macOUT = acMAC;

return true;

}

}

bool GetMacByNetBIOS(std::string& macOUT)

{

// 取得网卡列表

LANA_ENUM adapterList;

NCB Ncb;

memset(&Ncb, 0, sizeof(NCB));

Ncb.ncb_command = NCBENUM;

Ncb.ncb_buffer = (unsigned char *)&adapterList;

Ncb.ncb_length = sizeof(adapterList);

Netbios(&Ncb);

// 取得MAC

for (int i = 0; i < adapterList.length; ++i)

{

if (GetAdapterInfo(adapterList.lana[i], macOUT))

return true;

}

return false;

}

方法二：通过对控制台ipconfig /all命令重定向

#include <Windows.h>

#include <boost\regex.hpp>

namespace

{

#if 0

{

static const std::string beginMarkOfMAC("Physical Address. . . . . . . . . : ");

size_t begin = str.find(beginMarkOfMAC);

if(begin != std::string::npos)

{

begin += beginMarkOfMAC.size();

size_t end = str.find(endMarkOfMAC, begin);

if(end != std::string::npos)

{

macOUT = str.substr(begin, end - begin - 1);

return true;

}

}

return false;

}

#else

/// @brief 采用 boost::regex来提取MAC

bool ParseMac(const std::string& str, std::string& macOUT)

boost::regex::perl | boost::regex::icase);

boost::cmatch what;

if(boost::regex_search(str.c_str(), what, expression))

{

macOUT = what[1] + "-" + what[2] + "-" + what[3] + "-" + what[4] + "-" + what[5] + "-" + what[6];

return true;

}

return false;

}

#endif

}

bool GetMacByCmd(std::string& macOUT)

{

bool ret = false;

//初始化返回MAC地址缓冲区

SECURITY_ATTRIBUTES sa;

sa.bInheritHandle = TRUE;

//创建管道

if( CreatePipe(&hReadPipe, &hWritePipe, &sa, 0) == TRUE)

{

//控制命令行窗口信息

STARTUPINFO si;

//返回进程信息

PROCESS_INFORMATION pi;

si.cb = sizeof(STARTUPINFO);

GetStartupInfo(&si);

si.hStdError = hWritePipe;

si.hStdOutput = hWritePipe;

si.wShowWindow = SW_HIDE; //隐藏命令行窗口

si.dwFlags = STARTF_USESHOWWINDOW | STARTF_USESTDHANDLES;

//创建获取命令行进程

if (CreateProcess(NULL, "ipconfig /all", NULL, NULL, TRUE, 0, NULL, NULL, &si, &pi) == TRUE)

{

WaitForSingleObject(pi.hProcess, 3000); // 设置超时时间，防止Vista、Win7等操作系统卡死

unsigned long count;

CloseHandle(hWritePipe);

std::string strBuffer(1024 * 10, '\0'); // 准备足够大的缓冲区

if(ReadFile(hReadPipe, const_cast<char*>(strBuffer.data()), strBuffer.size() - 1, &count, 0) == TRUE)

{

strBuffer.resize(strBuffer.find_first_of('\0')); // 截掉缓冲区后面多余的'\0'

ret = ParseMac(strBuffer, macOUT);//提取MAC地址串

}

CloseHandle(pi.hThread);

CloseHandle(pi.hProcess);

}

CloseHandle(hWritePipe); // VS2010下调试，此处会有“An invalid handle was specified”的中断，直接运行正常，原因未知。VS2008上正常。

CloseHandle(hReadPipe);

}

return ret;
