httpclient

HttpClient是一个客户端的HTTP通信实现库。HttpClient的目标是发送和接收HTTP报文

get请求的简单样例

 public void testGet() throws IOException {
        //创建httpclient对象
        CloseableHttpClient httpClient = HttpClients.createDefault();
        //创建请求对象
        HttpGet httpGet = new HttpGet("http://localhost:8080/user/shop/status");
        //发送请求，接收结果
        CloseableHttpResponse response = httpClient.execute(httpGet);
        //获取服务器返回码
        int statusCode=response.getStatusLine().getStatusCode();
        System.out.println("服务器的返回码为"+statusCode);

        HttpEntity entity=response.getEntity();
        String body = EntityUtils.toString(entity);
        System.out.println("服务器的返回数据为"+body);
        //关闭资源
        response.close();
        httpClient.close();
    }
