String param= null; 
    try { 
        BufferedReader streamReader = new BufferedReader( new InputStreamReader(request.getInputStream(), "UTF-8"));
        StringBuilder responseStrBuilder = new StringBuilder();
        String inputStr;
        while ((inputStr = streamReader.readLine()) != null)
            responseStrBuilder.append(inputStr);
        
        JSONObject jsonObject = JSONObject.parseObject(responseStrBuilder.toString());
        param= jsonObject.toJSONString();
        System.out.println(param);
