Java解压gzip数据流

响应类型为：
content-encoding: gzip

gzip数据流解压

public static String streamToString2(InputStream in) throws IOException {
        //定义一个内存输出流
        ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
        //将流转换成字符串
        GZIPInputStream gis = new GZIPInputStream(in);
        int len1 = -1;
        byte[] b1 = new byte[1024];
        while ((len1 = gis.read(b1)) != -1) {
            byteArrayOutputStream.write(b1, 0, len1);
        }
        byteArrayOutputStream.close();
        //转化为数组
        // byte[] bytes = byteArrayOutputStream.toByteArray();
        return byteArrayOutputStream.toString();
    }

获取数据流

byte[] bytes = null;
DataInputStream dataInputStream = new DataInputStream(connection.getInputStream());
                ByteArrayOutputStream output = new ByteArrayOutputStream();
                byte[] buffer = new byte[1024];
                int length;
                while ((length = dataInputStream.read(buffer)) > 0) {
                    output.write(buffer, 0, length);
                }
                bytes =output.toByteArray();
