     1、打印网卡Mac地址 (HardwareAddress)

void MAC()
{
    
    
    foreach (QNetworkInterface netInterface, QNetworkInterface::allInterfaces())
    {
    
    
        	//设备名
            qDebug() << "Device:" << netInterface.name();

            //MAC地址
            qDebug() << "HardwareAddress:" << netInterface.hardwareAddress();

            QList<QNetworkAddressEntry> entryList = netInterface.addressEntries();

            //遍历每一个IP地址(每个包含一个IP地址，一个子网掩码和一个广播地址)
            foreach(QNetworkAddressEntry entry, entryList)
            {
    
    
                //IP地址
                qDebug() << "IP Address:" << entry.ip().toString();

                //子网掩码
                qDebug() << "Netmask:" << entry.netmask().toString();

                //广播地址
                qDebug() << "Broadcast:" << entry.broadcast().toString();
            }

            qDebug() << "\n\n";
    }
}

 

     2、打印CPU的ID - 纯C

          （注意:在release下可能会出错）

/// CpuId
#include <arpa/inet.h>
#include <fstream>
#include <unistd.h>
#include <cstring>

static bool get_cpu_id_by_asm(std::string & cpu_id)
{
    
    
    cpu_id.clear();

    unsigned int s1 = 0;
    unsigned int s2 = 0;
    asm volatile
    (
        "movl $0x01, %%eax; \n\t"
        "xorl %%edx, %%edx; \n\t"
        "cpuid; \n\t"
        "movl %%edx, %0; \n\t"
        "movl %%eax, %1; \n\t"
        : "=m"(s1), "=m"(s2)
    );

    if (0 == s1 && 0 == s2)
    {
    
    
        return(false);
    }

    char cpu[32] = {
    
     0 };
    snprintf(cpu, sizeof(cpu), "%08X%08X", htonl(s2), htonl(s1));
    std::string(cpu).swap(cpu_id);

    return(true);
}

static void parse_cpu_id(const char * file_name, const char * match_words, std::string & cpu_id)
{
    
    
    cpu_id.c_str();

    std::ifstream ifs(file_name, std::ios::binary);
    if (!ifs.is_open())
    {
    
    
        return;
    }

    char line[4096] = {
    
     0 };
    while (!ifs.eof())
    {
    
    
        ifs.getline(line, sizeof(line));
        if (!ifs.good())
        {
    
    
            break;
        }

        const char * cpu = strstr(line, match_words);
        if (NULL == cpu)
        {
    
    
            continue;
        }
        cpu += strlen(match_words);

        while ('\0' != cpu[0])
        {
    
    
            if (' ' != cpu[0])
            {
    
    
                cpu_id.push_back(cpu[0]);
            }
            ++cpu;
        }

        if (!cpu_id.empty())
        {
    
    
            break;
        }
    }

    ifs.close();
}

static bool get_cpu_id_by_system(std::string & cpu_id)
{
    
    
    cpu_id.c_str();

    const char * dmidecode_result = ".dmidecode_result.txt";
    char command[512] = {
    
     0 };
    snprintf(command, sizeof(command), "dmidecode -t 4 | grep ID > %s", dmidecode_result);

    if (0 == system(command))
    {
    
    
        parse_cpu_id(dmidecode_result, "ID:", cpu_id);
    }

    unlink(dmidecode_result);

    return(!cpu_id.empty());
}

static bool get_cpu_id(std::string & cpu_id)
{
    
    
    if (get_cpu_id_by_asm(cpu_id))
    {
    
    
        return(true);
    }
    if (0 == getuid())
    {
    
    
        if (get_cpu_id_by_system(cpu_id))
        {
    
    
            return(true);
        }
    }
    return(false);
}
///

 

     3、打印硬盘的ID

/// 获取硬盘Id
#include <stdio.h>		

#include <sys/ioctl.h>			//ioctl()的声明头文件
#include <linux/hdreg.h>		//硬盘参数头文件， hd_driveid结构声明头文件
#include <sys/fcntl.h>			//文件控制头文件

static void getDiskId()
{
    
    
    qDebug() << endl << "------------------------begin------------------------" << endl;

    QProcess process;
    process.start("hdparm -i /dev/sda");					//  核心
    process.waitForStarted();
    process.waitForFinished();
    QString str = process.readAllStandardOutput();
    int NoPos = str.indexOf("SerialNo=");
    int CoPos = str.indexOf("Config=");
    if(NoPos != -1 && CoPos != -1)
    {
    
    
        QString nStr = str.mid(NoPos+9,CoPos-NoPos-9);
        QString dStr;
        for(short index=0;index<nStr.size();++index)
        {
    
    
            char chr = nStr[index].toLatin1();
            if((chr >= '0' && chr <= '9') || (chr >= 'A' && chr <= 'Z') || (chr >= 'a' && chr <= 'z'))
            {
    
    
                dStr.append(chr);
            }
        }
        qDebug() << "result:" << dStr << endl;
    }
    qDebug() << endl << "------------------------end------------------------" << endl;
}
