[原创]获取QProcess::readAllStandardError的返回结果,怎么做都是乱码 [复制链接]

void dPublicFunction::execCMD( QString strcmd )
{
    QProcess p;
    p.start(strcmd);
    p.waitForStarted();
    p.waitForFinished();

    qDebug()<<ByteArray2String(p.readAllStandardError());
}


QString dPublicFunction::ByteArray2String(QByteArray ary)
{
    QTextCodec *codec = QTextCodec::codecForName("GBK");
    QString string = codec->toUnicode(ary);
    return string;
}

在main的地方这样写的

QString dPublicFunction::ByteArray2String(QByteArray ary)
{
    QTextCodec *codec = QTextCodec::codecForName("GBK");
    QString string = codec->toUnicode(ary);
    return string;
}
