Qt獲取CPU編號和硬盤序列號

windows下執行命令除了用cmd之外，還有個東西叫WMIC，非常強大，可以通過他獲取很多信息，包括硬件信息。

QString frmMain::getWMIC(const QString &cmd)
{
    //獲取cpu名稱：wmic cpu get Name
    //獲取cpu核心數：wmic cpu get NumberOfCores
    //獲取cpu線程數：wmic cpu get NumberOfLogicalProcessors
    //查詢cpu序列號：wmic cpu get processorid
    //查詢主板序列號：wmic baseboard get serialnumber
    //查詢BIOS序列號：wmic bios get serialnumber
    //查看硬盤：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");
}
