    try (S3Object s3Object = ossTemplate.getObject(bucket, fileName)) {
        response.setContentType("application/octet-stream; charset=UTF-8");
        IoUtil.copy(s3Object.getObjectContent(), response.getOutputStream());
    } catch (Exception e) {
        log.error("文件读取异常: {}", e.getLocalizedMessage());
    }
}

    if (files.length == 0) {
        return R.fail("文件内容不能为空");
    }
    try {
        // 获取文件夹名称
        for (MultipartFile file : files) {
            ossTemplate.putObject(folder, IdUtil.simpleUUID() + StrUtil.DOT + FileUtil.extName(file.getOriginalFilename()), file.getInputStream());
