Qt获取CPU编号和硬盘序列号

windows下执行命令除了用cmd之外，还有个东西叫WMIC，非常强大，可以通过他获取很多信息，包括硬件信息。

QString frmMain::getWMIC(const QString &cmd)
{
    //获取cpu名称：wmic cpu get Name
    //获取cpu核心数：wmic cpu get NumberOfCores
    //获取cpu线程数：wmic cpu get NumberOfLogicalProcessors
    //查询cpu序列号：wmic cpu get processorid
    //查询主板序列号：wmic baseboard get serialnumber
    //查询BIOS序列号：wmic bios get serialnumber
    //查看硬盘：wmic diskdrive get serialnumber
    QProcess p;
    p.start(cmd);
    p.waitForFinished();
    QString result = QString::fromLocal8Bit(p.readAllStandardOutput());
    QStringList list = cmd.split(" ");
    result = result.remove(list.last(), Qt::CaseInsensitive);
    result = result.replace("\r", "");
    result = result.replace("\n", "");
    result = result.simplified();
    return result;
}

QString frmMain::getCpuName()
{
    return getWMIC("wmic cpu get name");
}

QString frmMain::getCpuId()
{
    return getWMIC("wmic cpu get processorid");
}

QString frmMain::getDiskNum()
{
    return getWMIC("wmic diskdrive where index=0 get serialnumber");
}
