Как создать архивный файл с помощью libarchive ⇐ C++

[Anonymous]

I use libarchive to create a archive, and the source is a directory, I need create the archive with the same directory tree of the source directory, so I use the archive_read_disk_open and archive_read_disk_descend, but when i create a file with archive_write_open_filename(a, "xxx.zip"),there is always only a "xxx" file in the result zip file, I have to extract the "xxx" file and then rename the "xxx" to "xxx.zip", then I get the correct zip file

this is the code I use to create the zip file

bool KArchiveManager::pack(const QString& srcDirPath) { struct archive* a; struct archive_entry* entry; int r; a = archive_write_new(); archive_write_set_format_zip(a); archive_write_set_compression_compress(a); QString outPath= srcDirPath + ".zip"; r = archive_write_open_filename_w(a, outPath.toStdWString().c_str()); if (r != ARCHIVE_OK) { QString msg = QString("archive_write_open_filename_w : %1") .arg(archive_error_string(a)); emit packArchiveError(msg); archive_write_close(a); archive_write_free(a); return false; } QDir compressDir(srcDirPath); if (!compressDir.exists()) { emit packArchiveError(tr("compress dir not exist")); archive_write_close(a); archive_write_free(a); return false; } QStringList entryList = compressDir.entryList( QDir::Dirs | QDir::Files | QDir::NoDotAndDotDot); foreach(const QString & entryName, entryList) { struct archive* disk = archive_read_disk_new(); archive_read_disk_set_standard_lookup(disk); QString diskPath = compressDir.absoluteFilePath(entryName); r = archive_read_disk_open(disk, diskPath.toStdString().c_str()); if (r != ARCHIVE_OK) { QString msg = QString("archive_read_disk_open : %1") .arg(archive_error_string(disk)); emit packArchiveError(msg); archive_write_close(a); archive_write_free(a); archive_read_close(disk); archive_read_free(disk); return false; } while (true) { entry = archive_entry_new(); r = archive_read_next_header(disk, &entry); if (r == ARCHIVE_EOF) break; if (r != ARCHIVE_OK) { QString msg = QString("archive_read_next_header : %1") .arg(archive_error_string(disk)); emit packArchiveError(msg); archive_write_close(a); archive_write_free(a); archive_read_close(disk); archive_read_free(disk); return false; } archive_read_disk_descend(disk); QString sourcePath = archive_entry_pathname(entry); QString pathName = sourcePath.mid(srcDirPath.size() + 1); archive_entry_set_pathname(entry, pathName.toLocal8Bit()); r = archive_write_header(a, entry); if (r != ARCHIVE_OK) { QString msg = QString("archive_write_header : %1") .arg(archive_error_string(a)); emit packArchiveError(msg); archive_write_close(a); archive_write_free(a); archive_read_close(disk); archive_read_free(disk); return false; } //copydata if (archive_entry_filetype(entry) != AE_IFDIR) { QFile file(sourcePath); if (file.open(QIODevice::ReadOnly)) { QDataStream in(&file); while (!in.atEnd()) { QByteArray chunk = file.read(1024); archive_write_data(a, chunk.data(), chunk.size()); } file.close(); } } archive_entry_free(entry); } archive_read_close(disk); archive_read_free(disk); } archive_write_close(a); archive_write_free(a); return true; } How can I create the correct zip file instead of a zip file always contain the same name file of the param passed to the archive_write_open_filename?
