在Qt中使用WinRar解压(C++)，使用QProcess解压目录问题

QProcess process;
process.setProgram("C:/Program Files/WinRAR/WinRAR.exe");

QStringList arguments;
arguments << "x" << "-o+" << "压缩文件路径" << "解压目录路径";
process.setArguments(arguments);

process.start();
process.waitForFinished();

#include <QCoreApplication>
#include <QProcess>

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    QProcess process;
    process.setProgram("C:/Program Files/WinRAR/WinRAR.exe");

    QStringList arguments;
    arguments << "x" << "-o+" << "压缩文件路径" << "解压目录路径";
    process.setArguments(arguments);

    process.start();
    process.waitForFinished();

    return a.exec();
}
