    public static List<Map<String,String>> sum(String json) {
        JSONArray analyse = JSONArray.parseArray(json);
        List<Map<String, String>> okList = new LinkedList<Map<String, String>>();
        for (int i = 0; i < analyse.size(); i++) {
            // 遍历 jsonarray 数组，把每一个对象转成 json 对象
            Map<String, String> okMap = new HashMap<String, String>();
            String progId = NullTransfer.transfer(analyse.getJSONObject(i).get("progId").toString());
            String progType = NullTransfer.transfer(analyse.getJSONObject(i).get("progType").toString());
            String deployType = NullTransfer.transfer(analyse.getJSONObject(i).get("deployType").toString());
            okMap.put("progId", progId);
            okMap.put("progType", progType);
            okMap.put("deployType", deployType);

            JSONObject job = analyse.getJSONObject(i);
            Gson gson = new Gson();
            Map<String, String> dataMap = gson.fromJson(job.toJSONString(), new TypeToken<Map<String, Object>>() {
            }.getType());
            Object dataObject = dataMap.get("packs");
            List<Map<String, Object>> resourceList = (List<Map<String, Object>>) dataObject;
            for (int j = 0; j < resourceList.size(); j++) {
                String packId = NullTransfer.transfer(resourceList.get(j).get("packId").toString());
                //String progId = NullTransfer.transfer(resourceList.get(j).get("progId").toString());
                String packUri = NullTransfer.transfer(resourceList.get(j).get("packUri").toString());
                String packVersion = NullTransfer.transfer(resourceList.get(j).get("packVersion").toString());
                okMap.put("packId", packId);
                okMap.put("progId", progId);
                okMap.put("packUri", packUri);
                okMap.put("packVersion", packVersion);
            }
            okList.add(okMap);
        }
        return okList;
