QT查詢計算機硬體資訊

說明：

使用WMIC擷取計算機的一些硬體資訊，該方法隻能在windows上使用。

可擷取内容如下：

1. 查詢cpu資訊：wmic cpu get DeviceID,name,NumberOfCores,NumberOfLogicalProcessors
2. 擷取cpu名稱：wmic cpu get Name
3. 查詢cpu序列号：wmic cpu get processorid
4. 擷取cpu核心數：wmic cpu get NumberOfCores
5. 擷取cpu線程數：wmic cpu get NumberOfLogicalProcessors
6. 查詢主機闆序列号：wmic baseboard get serialnumber
7. 擷取主機闆資訊：wmic csproduct
8. 查詢BIOS序列号：wmic bios get serialnumber
9. 查詢磁盤資訊：wmic logicaldisk get name,Description,filesystem,size,freespace
10. 檢視硬碟：wmic diskdrive get serialnumber
11. 查詢第一個磁盤序列号：wmic diskdrive where index=0 get serialnumber
12. 查詢不為空的MAC位址：wmic nic where netconnectionid!=NULL get MacAddress
13. 查詢記憶體資訊： wmic memorychip get Capacity,TAG
14. 查詢系統資訊： wmic os get Caption,CSDVersion,CSName,SerialNumber,Version

代碼實作如下：

#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()    //擷取cpu名稱：wmic cpu get Name
{
    return getWMIC("wmic cpu get name");
}
QString getCpuId()  //查詢cpu序列号：wmic cpu get processorid
{
    return getWMIC("wmic cpu get processorid");
}
QString getCpuCoresNum()    //擷取cpu核心數：wmic cpu get NumberOfCores
{
    return getWMIC("wmic cpu get NumberOfCores");
}
QString getCpuLogicalProcessorsNum() //擷取cpu線程數：wmic cpu get NumberOfLogicalProcessors
{
    return getWMIC("wmic cpu get NumberOfLogicalProcessors");
}
QString getDiskNum()    //檢視硬碟：wmic diskdrive get serialnumber
{
    return getWMIC("wmic diskdrive where index=0 get serialnumber");
}
QString getBaseBordNum()    //查詢主機闆序列号：wmic baseboard get serialnumber
{
    return getWMIC("wmic baseboard get serialnumber");
}
QString getBiosNum()    //查詢BIOS序列号：wmic bios get serialnumber
{
    return getWMIC("wmic bios get serialnumber");
}
//其他一樣
           

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();
}
           

輸出結果：

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