HttpServletRequest 獲取入參

曾經調用過甲方的接口，正是爛得一逼，我想重新寫一個

就寫在這了，啥時候擺脫乙方這個垃圾身份，我就不用如此辛苦了，好難呀

代碼

 @PostMapping("/getParams")
    public String getParams( HttpServletRequest request,@RequestParam(required = false) MultipartFile multipartFile) throws IOException {
        // 對get/post 表單參數有效
        Map<String, String[]> parameterMap = request.getParameterMap();

        // 獲取json數據
        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 "===";
    }
