解析request的反馈信息

Map<String,String> params = new HashMap<String,String>();

        Map requestParams = request.getParameterMap();

        for (Iterator iter = requestParams.keySet().iterator(); iter.hasNext();) {

            String name = (String) iter.next();

            String[] values = (String[]) requestParams.get(name);

            String valueStr = "";

            for (int i = 0; i < values.length; i++) {

                valueStr = (i == values.length - 1) ? valueStr + values[i]

                        : valueStr + values[i] + ",";

            }

            params.put(name, valueStr);

        }
