windows下通过qt使用zlib将一个文件夹压缩成.zip后并保留文件夹内部文件的后缀

以下是一个使用Qt和zlib库将文件夹压缩成.zip并保留文件夹内部文件的后缀的示例代码：

#include <QtCore>
#include <QDebug>
#include <zlib.h>

    QFile outputFile(destinationFilePath);
    if (!outputFile.open(QIODevice::WriteOnly)) {
        qWarning() << "Failed to open output file" << destinationFilePath;
        return false;
    }

    // Create the ZIP header
    QByteArray header;
    header.append("PK\x03\x04", 4); // Local file header signature
    header.append("\x14\x00", 2); // Version needed to extract (minimum)
    header.append("\x00\x00", 2); // General purpose bit flag
    header.append("\x08\x00", 2); // Compression method (deflate)
    header.append(qint32(qDateTime.currentMSecsSinceEpoch() & 0xFFFFFFFF)); // Last modification time
    header.append("\x00\x00\x00\x00", 4); // CRC-32 (unknown)
    header.append("\x00\x00\x00\x00", 4); // Compressed size (unknown)
    header.append("\x00\x00\x00\x00", 4); // Uncompressed size (unknown)
    header.append(qint16(sourceDirPath.length())); // File name length
    header.append("\x00\x00", 2); // Extra field length
    header.append(sourceDirPath.toUtf8()); // File name

    // Write the header to the output file
    if (outputFile.write(header) != header.length()) {
        qWarning() << "Failed to write ZIP header";

    }

这个函数接受两个参数：源文件夹的路径和目标.zip文件的路径。它使用zlib库将源文件夹中的所有文件压缩成.zip文件。在压缩过程中，每个文件都会添加到.zip文件中，并保留其文件名后缀。压缩完成后，该函数返回true，否则返回false。
