C++ 硬件信息 获取CPU序列号

标签：硬件   cpu   序列号   

    获取计算机CPU序列号的方法很多，这里采用的是命令行的形式获取，可以获取CPU的序列号，很简单，直接上代码。

【1】头文件

#if !defined(AFX_14BEC153_17B9_47BE_845F_71A27BF26B59__INCLUDED_)
#define AFX_14BEC153_17B9_47BE_845F_71A27BF26B59__INCLUDED_

#if _MSC_VER > 1000
#pragma once
#endif // _MSC_VER > 1000

#include <iostream>
#include <string>
#include <windows.h>

using namespace std;

//--------------------------------------------------------------
//						CPU序列号
//--------------------------------------------------------------
BOOL GetCpuByCmd(char *lpszCpu, int len=128);


#endif // !defined(AFX_14BEC153_17B9_47BE_845F_71A27BF26B59__INCLUDED_)

【2】CPP

#include "stdafx.h"
#include "CpuID.h"


//--------------------------------------------------------------
//						CPU序列号
//--------------------------------------------------------------
BOOL GetCpuByCmd(char *lpszCpu, int len/*=128*/)
{	
    const long MAX_COMMAND_SIZE = 10000; // 命令行输出缓冲大小	
    WCHAR szFetCmd[] = L"wmic cpu get processorid"; // 获取CPU序列号命令行	
    const string strEnSearch = "ProcessorId"; // CPU序列号的前导信息

    BOOL   bret = FALSE;
    HANDLE hReadPipe = NULL; //读取管道
    HANDLE hWritePipe = NULL; //写入管道	
    PROCESS_INFORMATION pi;   //进程信息	
    STARTUPINFO			si;	  //控制命令行窗口信息
    SECURITY_ATTRIBUTES sa;   //安全属性

    char			szBuffer[MAX_COMMAND_SIZE + 1] = { 0 }; // 放置命令行结果的输出缓冲区
    string			strBuffer;
    unsigned long	count = 0;
    long			ipos = 0;

    memset(&pi, 0, sizeof(pi));
    memset(&si, 0, sizeof(si));
    memset(&sa, 0, sizeof(sa));

    pi.hProcess = NULL;
    pi.hThread = NULL;
    si.cb = sizeof(STARTUPINFO);
    sa.nLength = sizeof(SECURITY_ATTRIBUTES);
    sa.lpSecurityDescriptor = NULL;
    sa.bInheritHandle = TRUE;

    //1.0 创建管道
    bret = CreatePipe(&hReadPipe, &hWritePipe, &sa, 0);
    if (!bret)
    {
        goto END;
    }

    //2.0 设置命令行窗口的信息为指定的读写管道
    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;

    //3.0 创建获取命令行的进程
    bret = CreateProcess(NULL, szFetCmd, NULL, NULL, TRUE, 0, NULL, NULL, &si, &pi);
    if (!bret)
    {
        goto END;
    }

    //4.0 读取返回的数据
    WaitForSingleObject(pi.hProcess, 500/*INFINITE*/);
    bret = ReadFile(hReadPipe, szBuffer, MAX_COMMAND_SIZE, &count, 0);
    if (!bret)
    {
        goto END;
    }

    //5.0 查找CPU序列号
    bret = FALSE;
    strBuffer = szBuffer;
    ipos = strBuffer.find(strEnSearch);

    if (ipos < 0) // 没有找到
    {
        goto END;
    }
    else
    {
        strBuffer = strBuffer.substr(ipos + strEnSearch.length());
    }

    memset(szBuffer, 0x00, sizeof(szBuffer));
    strcpy_s(szBuffer, strBuffer.c_str());

    //去掉中间的空格 \r \n
    int j = 0;
    for (int i = 0; i < strlen(szBuffer); i++)
    {
        if (szBuffer[i] != ' ' && szBuffer[i] != '\n' && szBuffer[i] != '\r')
        {
            lpszCpu[j] = szBuffer[i];
            j++;
        }
    }

    bret = TRUE;

END:
    //关闭所有的句柄
    CloseHandle(hWritePipe);
    CloseHandle(hReadPipe);
    CloseHandle(pi.hProcess);
    CloseHandle(pi.hThread);

    return(bret);
}
