    //添加文件
    QFile file(path + "/test.txt");
    if (!file.exists())
    {
        return;
    }
    file.open(QIODevice::ReadOnly);
    writer->addFile("test.txt", file.readAll());

    QZipReader reader(path + "/test.zip");
    reader.extractAll(path);

    QFile file(path);
    file.open(QIODevice::WriteOnly);
    file.write(reader.fileData(QString::fromLocal8Bit("%1").arg(path + "/Desktop")));
    file.close();
    reader.close();
