public class ZipUtils {   		@Test	public void getZipFile() throws IOException {           String generateUrl = "http://文件地址";		//从服务器请求文件流,具体代码就不贴了//        CloseableHttpResponse response = HttpSender.toPost(FILE_URL, null);//        InputStream inputStream = response.getEntity().getContent();		URL url = new URL(generateUrl);		URLConnection conn = url.openConnection();		InputStream inputStream = conn.getInputStream();        ByteArrayOutputStream byteArray = new ByteArrayOutputStream();        byte[] buff = new byte[1024*1024]; //如果是稍微大的文件,这里配置的大一些        int len = 0;        while((len = inputStream.read(buff)) > 0) {               //把从服务端读取的文件流保存到ByteArrayOutputSteam中            byteArray.write(buff, 0, len);            byteArray.flush();        }        inputStream.close();//        response.close();        //GZIPInputstream解压文件,然后读取文件        BufferedReader bufferedReader = new BufferedReader(                new InputStreamReader(new GZIPInputStream(                        new ByteArrayInputStream(byteArray.toByteArray())), "utf-8"));        String line = null;        while((line = bufferedReader.readLine()) != null) {               System.out.println(line);        }    }	}
