Java 两种下载到本地方法

一、获得InputStream数据

  InputStream input = obsObject.getObjectContent();
  FileOutputStream fileOut = new FileOutputStream(new File("localPath/fileName"));
  byte[] b = new byte[1024];
  while ((input.read(b)) != -1) {
      fileOut .write(b);
  }

二、获得 byte[]数据

  byte[] data = fileStorageClient.downloadFile(group, path, new DownloadByteArray());         
  FileOutputStream fileOut = new FileOutputStream("localPath/fileName");
  fileOut.write(data);
  fileOut.close();
