Qt使用wmic获取硬件序列号

#include "hardware_info.h"
#include <QProcess>
#include <QDebug>
hardware_info::hardware_info()
{

}

QString hardware_info::get_cpu_id()

    arg << "cpu" << "get"<<"ProcessorID";
    QString result = run_process(arg);
    result = result.remove("PROCESSORID").trimmed();
    return result;
}

QString hardware_info::get_harddisk_id()
{
    QStringList arg;
    //arg << "diskdrive" << "where"<<"index=0"<<"get"<<"serialnumbe";//获取第一个磁盘序列号

//    arg << "diskdrive" << "where"
//            << "deviceid='\\\\\\\\.\\\\PHYSICALDRIVE0'"
//            << "get" << "serialnumber,model,size";
