</dependency>
0.2 代码
//1. 打开浏览器 创建httpclient对象
CloseableHttpClient httpClient = HttpClients.createDefault();
//2. 输入网址
HttpGet httpGet = new HttpGet("http://www.baidu.com");
//3. 发送请求
CloseableHttpResponse httpResponse = httpClient.execute(httpGet);
//4. 响应结果
HttpEntity httpEntity = httpResponse.getEntity();
//5. 解析结果
String result = EntityUtils.toString(httpEntity, "utf-8");
System.out.println(result);
1. 实操
