关于http请求：pad和浏览器之间有什么区别吗？

 public Object downFile(String filepath, HttpServletRequest request, HttpServletResponse response) {

            filepath = fileinfoService.getFilePath(fileInfo);
            File file = new File(filepath);
            if(file.exists()){
                inputStream = new FileInputStream(file);

HTTP请求：在pc上面访问没有问题，在pad上面范围图片没有问题，但是视频，报
