在Android中解压缩gzip json响应为字符串

public static String decompressGzip(byte[] compressedData) throws IOException {
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    ByteArrayInputStream bais = new ByteArrayInputStream(compressedData);
    GZIPInputStream gzipInputStream = new GZIPInputStream(bais);
    byte[] buffer = new byte[1024];
    int len;
    while ((len = gzipInputStream.read(buffer)) != -1) {
        baos.write(buffer, 0, len);
    }
    gzipInputStream.close();
    baos.close();
    return baos.toString("UTF-8");
}
