public String sendLogs(String data) throws Exception{
        String result = null;
        CloseableHttpClient httpClient = HttpClients.createDefault();
        try{
            HttpPost httpPost = new HttpPost(url);
            HttpEntity reqEntity = MultipartEntityBuilder.create()
                .addPart("xtid",new StringBody(xtid, ContentType.APPLICATION_JSON))
                .addPart("logsXml",new StringBody(data,ContentType.APPLICATION_JSON))
                .build();

            httpPost.setEntity(reqEntity);
            CloseableHttpResponse response = httpClient.execute(httpPost);
           try{
               HttpEntity resEntity = response.getEntity();
               if(resEntity != null){
                   result  = IOUtils.toString(resEntity.getContent(),"utf-8");
               }
               EntityUtils.consume(resEntity);
               return result;

           }finally {
               response.close();
           }
        }finally {
            httpClient.close();
        }
    }
