测试 调用

    @RequestMapping("/img")
    public void upload(MultipartFile img, String userName,HttpServletRequest request) throws IOException {
     

        FileInputStream fileInputStream = (FileInputStream) img.getInputStream();
        String s = QiniuUtils.uploadQNImg(fileInputStream, null);
        System.out.println(s);

    }
