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"));
