InputStream 和 byte[] 互转

InputStream 转 byte[]

ByteArrayOutputStream bos = new ByteArrayOutputStream();byte[] bs = new byte[1024]; int len = -1;while ((len = is.read(bs)) != -1) {bos.write(bs, 0, len);}byte b[] = bos.toByteArray();bos.close();

byte转InputStream

byte[] data; InputStream is = new ByteArrayInputStream(data);
