Java中拉取网络图片上传至MinIO服务器

Question

最近使用minio的时候，发现直接获取文件流只能传几kb，只有存到本地再从本地获取流上传才能传完整的图片，有什么指点吗，是我哪里写错了吗，contentType的几种几乎都试过了,包括(image/jpeg、application/octet-stream等)，minio版本7.0.2，代码如下

    public static void main(String[] args) {
        String downloadUrl = "https://image.baidu.com/search/down?tn=download&ipn=dwnl&word=download&ie=utf8&fr=result&url=https%3A%2F%2Fgss0.baidu.com%2F7LsWdDW5_xN3otqbppnN2DJv%2Fforum%2Fpic%2Fitem%2Fe61190ef76c6a7ef7b165d61eafaaf51f3de6641.jpg&thumburl=https%3A%2F%2Fss2.baidu.com%2F-vo3dSag_xI4khGko9WTAnF6hhy%2Fimage%2Fh%253D300%2Fsign%3Dd554e55ac32a28345ca6300b6bb5c92e%2Fe61190ef76c6a7ef7b165d61eafaaf51f3de6641.jpg";


        URL url = null;
        InputStream is2 = null;


        try {
//          url对象
            url = new URL(downloadUrl);

            HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
            urlConnection.setDoInput(true);
            urlConnection.connect();
//          查看contentType
            String contentType = urlConnection.getContentType();
            System.out.println(contentType);

            is2 = urlConnection.getInputStream();


            MinioClient minIoUtils = new MinioClient("http://127.0.0.1:9000", "admin", "12345678", false);
            PutObjectOptions putObjectOptions = new PutObjectOptions(is2.available(), -1);
            putObjectOptions.setContentType("image/jpeg");
//            传流到minio
            minIoUtils.putObject("backet", "home/a.jpg", is2, putObjectOptions);

        } catch (Exception e) {
            System.out.println("minio");
            e.printStackTrace();
        }
    }

你不要下载百度的图片，你换成其他的图片试试；

百度图片做了反爬策略，有影响。
