文件转字节数组：
private byte[] fileConvertToByteArray(File file) { byte[] data = null; try { FileInputStream fis = new FileInputStream(file); ByteArrayOutputStream baos = new ByteArrayOutputStream(); int len; byte[] buffer = new byte[1024]; while ((len = fis.read(buffer)) != -1) { baos.write(buffer, 0, len); } data = baos.toByteArray(); fis.close(); baos.close(); } catch (Exception e) { e.printStackTrace(); } return data; }
