java url参数 转为 HashMap

Post 或 Get 的参数 

如：

&TalkDurAction=110&SrcTrunkName=&DstTrcunkName=&PinCode=&Status=ANSWERED&Type=Inbound　

用法

//HttpServletRequest request对象获取Post参数
BufferedReader streamReader = new BufferedReader( new InputStreamReader(request.getInputStream(), "UTF-8"));
StringBuilder responseStrBuilder = new StringBuilder();
String inputStr;
while ((inputStr = streamReader.readLine()) != null) {
    responseStrBuilder.append(inputStr);
    System.out.println("---------------------------------"+inputStr);
}
//获取POST参数 map
System.out.println("doPost() POST参数 " + responseStrBuilder.toString());
String strPostParam=responseStrBuilder.toString(); //POST参数
HashMap<String,String> mapPostParam = getUrlParams(responseStrBuilder.toString());
//取值
String strId = mapPostParam .get("Id").toString();

        Map map = new HashMap(0);
        if (StringUtils.isBlank(param)) {
            return map;

            String[] p = params[i].split("=");
            if (p.length == 2) {
                map.put(p[0], p[1]);
            }
        }
        return map;
    }

    //将map转换成url
    public static String getUrlParamsByMap(Map map) {
