如何用java读取php的gzencode函数输出的压缩字符

phpjavagzdecode

输入的字符串为php的gzencode压缩的字符串,可以用gzdecode解开,但是用java的java.util.zip.GZIPInputStream读入字符串时,总是提示:
java.util.zip.ZipException: Not in GZIP format
希望有经验的朋友帮我解答一下,我的代码如下:

 JAVAimport java.io.ByteArrayInputStream;import java.io.ByteArrayOutputStream;import java.io.InputStream;import java.io.OutputStream;import java.util.zip.GZIPInputStream;import java.util.zip.GZIPOutputStream;public class Gzdecode {    public static void decompress(InputStream is, OutputStream os)            throws Exception {        GZIPInputStream gis = new GZIPInputStream(is);        int count;        byte data[] = new byte[BUFFER];        while ((count = gis.read(data, 0, BUFFER)) != -1) {            os.write(data, 0, count);        }        gis.close();    }    public static byte[] decompress(byte[] data) throws Exception {          ByteArrayInputStream bais = new ByteArrayInputStream(data);          ByteArrayOutputStream baos = new ByteArrayOutputStream();           // 解压缩           decompress(bais, baos);           data = baos.toByteArray();          baos.flush();          baos.close();           bais.close();           return data;      }        public static void main(String[] args) throws Exception    {        String input="";        byte[] data=input.getBytes("UTF-8");        byte[] data_decompress=decompress(data);        System.out.write(data_decompress);
