QT查询计算机硬件信息

说明：

使用WMIC获取计算机的一些硬件信息，该方法只能在windows上使用。

可获取内容如下：

1. 查询cpu信息：wmic cpu get DeviceID,name,NumberOfCores,NumberOfLogicalProcessors
2. 获取cpu名称：wmic cpu get Name
3. 查询cpu序列号：wmic cpu get processorid
4. 获取cpu核心数：wmic cpu get NumberOfCores
5. 获取cpu线程数：wmic cpu get NumberOfLogicalProcessors
6. 查询主板序列号：wmic baseboard get serialnumber
7. 获取主板信息：wmic csproduct
8. 查询BIOS序列号：wmic bios get serialnumber
9. 查询磁盘信息：wmic logicaldisk get name,Description,filesystem,size,freespace
10. 查看硬盘：wmic diskdrive get serialnumber
11. 查询第一个磁盘序列号：wmic diskdrive where index=0 get serialnumber
12. 查询不为空的MAC地址：wmic nic where netconnectionid!=NULL get MacAddress
13. 查询内存信息： wmic memorychip get Capacity,TAG
14. 查询系统信息： wmic os get Caption,CSDVersion,CSName,SerialNumber,Version

代码实现如下：

#include <QProcess>
QString getWMIC(const QString &cmd)
{
    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 getCpuName()    //获取cpu名称：wmic cpu get Name
{
    return getWMIC("wmic cpu get name");
}
QString getCpuId()  //查询cpu序列号：wmic cpu get processorid
{
    return getWMIC("wmic cpu get processorid");
}
QString getCpuCoresNum()    //获取cpu核心数：wmic cpu get NumberOfCores
{
    return getWMIC("wmic cpu get NumberOfCores");
}
QString getCpuLogicalProcessorsNum() //获取cpu线程数：wmic cpu get NumberOfLogicalProcessors
{
    return getWMIC("wmic cpu get NumberOfLogicalProcessors");
}
QString getDiskNum()    //查看硬盘：wmic diskdrive get serialnumber
{
    return getWMIC("wmic diskdrive where index=0 get serialnumber");
}
QString getBaseBordNum()    //查询主板序列号：wmic baseboard get serialnumber
{
    return getWMIC("wmic baseboard get serialnumber");
}
QString getBiosNum()    //查询BIOS序列号：wmic bios get serialnumber
{
    return getWMIC("wmic bios get serialnumber");
}
//其他一样
           

使用示例：

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    qDebug()<<"getCpuName:"<<getCpuName();
    qDebug()<<"getCpuId:"<<getCpuId();
    qDebug()<<"getCpuCoresNum:"<<getCpuCoresNum();
    qDebug()<<"getCpuLogicalProcessorsNum:"<<getCpuLogicalProcessorsNum();
    qDebug()<<"getDiskNum:"<<getDiskNum();
    qDebug()<<"getBaseBordNum:"<<getBaseBordNum();
    qDebug()<<"getBiosNum:"<<getBiosNum();
}
           

输出结果：

getCpuName: "Intel(R) Core(TM) i5-9500 CPU @ 3.00GHz"
getCpuId: "BFEBFBFF000906EA"
getCpuCoresNum: "6"
getCpuLogicalProcessorsNum: "6"
getDiskNum: "WD-WCC6Y4VJNRVN"
getBaseBordNum: ""
getBiosNum: "M70E1VP5"
