HarmonyOS 鸿蒙Next gzip api在哪，怎么压缩

原Andorid里这么压缩字符串的：

public static byte[] compress(String string) {
    ByteArrayOutputStream os = new ByteArrayOutputStream(string.length());
    GZIPOutputStream gos = null;
    byte[] compressed = new byte[1];
    try {
        gos = new GZIPOutputStream(os);
        gos.write(string.getBytes(UTF_8));
        CloseHelper.closeQuietly(gos); // must close here
        compressed = os.toByteArray();
    } catch (Exception e) {
        PrintUtil.printlnException(e);
    } finally {
        CloseHelper.closeQuietly(os);
    }
    return compressed;
}
