Poco::Zip::Compress壓縮文件夾

Poco::Zip::Compress壓縮文件夾

Poco::Zip的壓縮代碼片段在網上資料甚少，之前項目遇到過，根據網上搜的沒用，後來費了九牛二虎之力才弄出這段代碼，好了，廢話不多說，上代碼：

//@inputDirPath    壓縮文件目錄
//@outputFilePath  文件目錄壓縮後的壓縮文件名，如game.zip
bool compress(QString inputDirPath, QString outputFilePath)
{
	//解決文件名中文亂碼問題
	#define RC_ToQString(str) (QTextCodec::codecForName("GB2312")->toUnicode(str));  //return QString
	#define RC_FromQString(str) (QTextCodec::codecForName("GB2312")->fromUnicode(str).constData()) //return const char*
	QDir rootDir = QDir(inputDirPath);
	std::ofstream out(RC_FromQString(outputFilePath), std::ios::binary | std::ios::trunc);
	Poco::Zip::Compress c(out, true);
	QStringList filters;
	filters << "*.*";
	QFileInfoList infoList = rootDir.entryInfoList(filters, QDir::Files);
	for (int i = 0; i < infoList.size();i++)
	{
		QFileInfo fi = infoList[i];
		QString item = fi.absoluteFilePath();
		Poco::File aFile(item.toStdString());
		if (!aFile.exists())
		{
			qDebug() << "file not found" << item;
		}
		else
		{
			Poco::Path aEntry(item.toStdString());
			if (aFile.isDirectory())
			{
				aEntry.makeDirectory();
				c.addRecursive(aEntry, Poco::Zip::ZipCommon::CL_MAXIMUM, false);
			}
			else
			{
				aEntry.makeFile();
				c.addFile(aEntry, fi.fileName().toStdString());
			}
		}
	}

	c.close();
	return true;
	
}
