QT向已有ZIP中追加文件
向已有ZIP中追加文件，使用qt自带的QZipWriter和quazip库均失败了，要么格式损坏、要么ZIP里面的原有的文件清空了
使用7z.exe可以实现 : 指令 7z.exe a A.zip B.txt，使用代码控制如下
#include <QCoreApplication>
#include <QFileInfo>
#include <QProcess>
#include <QDebug>int addFileToZip(const QString &zipFilePath, const QString &fileToAddPath){QString sevenZipPath = "F:\\data\\7z\\7z.exe";QProcess process;process.setWorkingDirectory(QFileInfo(sevenZipPath).absolutePath());QStringList arguments;arguments << "a" << zipFilePath << fileToAddPath;process.start(sevenZipPath, arguments);process.waitForFinished();if (process.exitCode() != 0) {qDebug() << "7z.exe process failed:" << process.readAllStandardError();return -1;}qDebug() << "File added to ZIP successfully.";return 0;
}
int main(int argc, char *argv[]) {//7z.exe a A.zip B.txtQString zipFilePath = "F:\\data\\A.zip";QString fileToAddPath = "F:\\data\\B.txt";addFileToZip(zipFilePath, fileToAddPath);return 0;
}
