通过文件流上传对象Demo 代码不完善

[mudao]

    public static void SimpleUploadFileFromStream() {
      ....
        String key = "aaa/bbb.jpg";
        //这里加载文件
        File localFile = new File("src/test/resources/len10M.txt");
        //这里创建流,但未见读取文件代码
        InputStream input = new ByteArrayInputStream(new byte[10]);
        ObjectMetadata objectMetadata = new ObjectMetadata();

        objectMetadata.setContentLength(10);

        objectMetadata.setContentType("image/jpeg");
        //这里直接传入了input
        PutObjectRequest putObjectRequest =new PutObjectRequest(bucketName, key, input, objectMetadata);

        putObjectRequest.setStorageClass(StorageClass.Standard_IA);
      ....
  }
