QFileInfo所有者＆amp;小组是空的

Question

这是我的插槽：

void MainWindow::writeOnFile(const QString &path)
{
    // Get info files :
    QFileInfo fileInfo(path);
    QString name = fileInfo.fileName();
    QString lastModif = fileInfo.lastModified().toString();
    QString owner = fileInfo.owner();
    QString group = fileInfo.group();
    QString lastRead = fileInfo.lastRead().toString();
    QString created = fileInfo.created().toString();


    // Write on Logs :
    QString filename = "C:\\Users\\Sherlock\\Desktop\\logs.txt";
    QFile file ( filename );
    if ( file.open(QIODevice::WriteOnly | QIODevice::Append | QIODevice::Text) )
    {
        QTextStream stream( &file );
        stream << "The file " << name
               << " was first created on " << created
               << ", was last read on " << lastRead
               << " and was last modified on " << lastModif
               << ". The owner is " << owner
               << ". The group is " << group
               << endl;
    }
}

这是我的输出：

在Windows [...]上返回一个空字符串。

因此，记录了{{1}}以这种方式行事。
