httpClient 进行get请求

         String url = baseUrl;
         logger.info("checkIfTheFolderIsExist");
         CloseableHttpClient httpClient = HttpClientBuilder.create().build();
         URI uri = new URIBuilder()
                 .setPath(url)
                 .setParameter("token", token)
                 .setParameter("folderName", folderName)
                 .setParameter("folderId", folderId)
                 .build();
         HttpGet get = new HttpGet(uri);
         CloseableHttpResponse response = httpClient.execute(get);
         logger.info(EntityUtils.toString(response.getEntity(), "utf-8"));
