OSS通过javaAPI分段下载的这个异常怎么解决啊?

尝试通过GetObjectRequest获取Object,代码这样的

                ObjectMetadata meta = client.getObjectMetadata(DEFAULT_BUCKET_NAME,"test1");
                Long fileLength = meta.getContentLength();
                OSSObject object;
                GetObjectRequest getObjectRequest = new GetObjectRequest(DEFAULT_BUCKET_NAME, "test1");
                long count = fileLength / 1000   1;
                long start = 0;
                long end = 1000;
                for (long i = 0; i < count; i  ) {
                        start = i * 1000;
                        end = (i   1) * 1000;
                        // 获取0~1000字节范围内的数据
                        getObjectRequest.setRange(start, end);
                        // 获取Object,返回结果为OSSObject对象
                        System.out.println("prepare to get 1000: "   i);
                        object = client.getObject(getObjectRequest);

                        InputStream content = object.getObjectContent();
                        System.out.println("prepare to write 1000: "   i);
                        try {
                                FileOutputStream writeFile = new FileOutputStream("D:\\temp\\down\\Mlog.txt", true);
                                OutputStreamWriter out = new OutputStreamWriter(writeFile);
                                out.write(content.read());
                                System.out.println("write 1000: "   i);
                                content.close();
                                out.close();
                        } catch (FileNotFoundException e) {
                                e.printStackTrace();
                        } catch (IOException e) {
                                  e.printStackTrace();
                 }



运行到红色这一行,就一直连接不上

直接用OSSObject object = client.getObject(DEFAULT_BUCKET_NAME, "test1");  是没有问题的

    ReOSS通过javaAPI分段下载的这个异常怎么解决啊?
    分段读是可以的呀,但是代码中几个问题:
    1.  long count = fileLength / 1000  1; 这个可能会出问题,如果fileLength能被1000整除, 1 已经越界
    2. range应该在0-(fileLength-1)之间,end = (i 1)*1000有可能大于fileLength-1
    3. out.write(content.read());只输出一个字符到out,没有读全object 内容
    4.  content.close(); 出错,out.close(); 不能执行到

    ReOSS通过javaAPI分段下载的这个异常怎么解决啊?
    今天直接用了HttpURLConnection,一旦设置了Range,也是异常
    我是这样写的 setRequestProperty("Range", "bytes=0-100")
    异常是

    ReOSS通过javaAPI分段下载的这个异常怎么解决啊?
    这个 因为我是写个testcase,所以用的文件我知道不会整除的,就忽略细节了
    content.read() 是写错了,不过这些都在出异常的位置之后,应该不会有影响的
