/**     * 读取输入流数据     * //此方法是用于缓存H5网络请求数据，解决inputStream对象不能重复复用的问题     */    public static byte[] streamToData(InputStream uristream) {        ByteArrayOutputStream outStream = null;        try {            outStream = new ByteArrayOutputStream();            byte[] buffer = new byte[1024];            int len = 0;            while ((len = uristream.read(buffer)) != -1) {                outStream.write(buffer, 0, len);            }            return outStream.toByteArray();        } catch (Exception e) {            return null;        } finally {            try {                if(uristream !=null) {                    uristream.close();                }                if (outStream != null) {                    outStream.close();                }            } catch (IOException e) {                e.printStackTrace();            }        }    }

byte[] data = FileUtils.streamToData(inputstream);//把需要复用的inputStream保存为data

InputStream in1 = new ByteArrayInputStream(data)InputStream in2 = new ByteArrayInputStream(data)
