我的项目是使用命令行进行samba映射网络到虚拟磁盘
QProcess process;

process.setProgram("cmd.exe");

QStringList wCmd;

wCmd << "/c"  << "net use Z: \\\\192.168.2.109\\nfs_space"; 

以下两条指令也可以使用，但是"/c"不可少
//<<"ping 192.168.2.109"
//<< "net view 192.168.2.109"

process.setArguments(wCmd);

process.start();

if(process.waitForStarted()) {

     qDebug() << "start success";

}

if(process.waitForFinished()) {

     qDebug()<<"process read"<<QString::fromLocal8Bit(process.readAllStandardOutput());

           qDebug()<< "process error" << QString::fromLocal8Bit(process.readAllStandardError());

}

return QFile::exists("Z:/lircos.db");

QProcess process;

    process.setProgram("cmd.exe");

    QStringList swCmd;

    swCmd << "/c"  << "net use Z: \/delete";

    process.setArguments(swCmd);

    process.start();

    process.waitForStarted();

    process.waitForFinished();

    QStringList wCmd;

    QString server_ip = QHMISetting::GetInstance()->GetConfigInfo()->server_ip;

    wCmd << "/c"  << "net use Z: \\\\" + server_ip + "\\luoshi";

    process.setArguments(wCmd);

    process.start();

    process.waitForStarted();

    process.waitForFinished();

    return QFile::exists("Z:/nfs_space/lircos.db");
