本文介绍了一个使用Java HttpClient进行网络请求的具体实现案例。该案例通过构建HTTP GET请求来发送搜索查询，并解析返回的JSON结果，展示了如何获取并打印出搜索结果中的特定数据。

public void doGet(String text) {
        CloseableHttpClient httpClient = HttpClientBuilder.create().build();
        String ip = environment.getProperty("ip");
        String port = environment.getProperty("port");
        String url = "http://" + ip + ":" + port + "/search?text=" + text;
        HttpGet httpGet = new HttpGet(url);
        CloseableHttpResponse response = null;
        try {
            response = httpClient.execute(httpGet);
            HttpEntity entity = response.getEntity();
            if (entity != null) {
                System.out.println("内容"+EntityUtils.toString(entity));
                String res = EntityUtils.toString(entity);
                JSONObject jsonResult = new JSONObject(res);
                JSONArray jsonArr = jsonResult.getJSONArray("rows");
                for (int i = 0; i < jsonArr.size(); i++) {
                    JSONObject jObject = jsonArr.getJSONObject(i);
                    //
                }
            }
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            // 释放资源
            try {
                response.close();
                httpClient.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
