如何从c ++中读取PHP -gzcompress-数据

Question

这是我的c ++代码：

#include <QtCore/QCoreApplication>
#include <QtCore/QDebug>
#include <QFile>
#include <QByteArray>

QByteArray UnZip (QString zipfilename)
{
    QFile infile(zipfilename);
    infile.open(QIODevice::ReadOnly);
    //QByteArray uncompressedData = infile.readAll();
    QByteArray uncompressedData = qUncompress(infile.readAll());
    infile.close();

    return uncompressedData;
}

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

    //QString path = "/Users/davide/Desktop/fh8RkbUf";
    QString path = "/Users/davide/Desktop/test";

    QByteArray data = UnZip(path);

    qDebug() << "message";

    return a.exec();
}

返回qUncompress: Z_DATA_ERROR: Input data is corrupted

但是，数据应该是zlib压缩的，并且php的gzuncompress($data)可以正常工作。

此外，cat file | uncompress会返回错误。

代码php端是

$data = gzcompress($data, 6);
$success = file_put_contents($file, $data);
