HttpServletRequest 获取入参

曾经调用过甲方的接口，正是烂得一逼，我想重新写一个

就写在这了，啥时候拜托乙方这个垃圾身份，我就不用如此辛苦了，好难呀

代码

 @PostMapping("/getParams")
    public String getParams( HttpServletRequest request,@RequestParam(required = false) MultipartFile multipartFile) throws IOException {
        // 对get/post 表单参数有效
        Map<String, String[]> parameterMap = request.getParameterMap();

        // 获取json数据
        ServletInputStream inputStream = request.getInputStream();

        StringBuilder sb = new StringBuilder();
        String line = null;

        BufferedReader br = new BufferedReader(new InputStreamReader(inputStream));
        while ((line = br.readLine()) != null) {
            sb.append(line);
        }
        return "===";
    }
