1、导入依赖

<dependencies><!-- HttpClient --><dependency><groupId>org.apache.httpcomponents</groupId><artifactId>httpclient</artifactId><version>4.5.3</version></dependency><!-- 日志 --><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId><version>1.7.25</version></dependency>
</dependencies>

2、CrawlerFirst

package com.atguigu.crawler.test;
import org.apache.http.HttpEntity;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;
import java.io.IOException;
public class CrawlerFirst {public static void main(String[] args) throws IOException {//1、打开浏览器，创建HttpClient对象CloseableHttpClient httpClient = HttpClients.createDefault();//2、输入网址，发起get请求，获取响应HttpGet httpGet = new HttpGet("https://blog.csdn.net/m0_65152767?spm=1010.2135.3001.5343");//3、使用 HttpClient 发起请求，获取响应CloseableHttpResponse response = httpClient.execute(httpGet);//4、解析响应，获取数据if (response.getStatusLine().getStatusCode() == 200) {HttpEntity httpEntity = response.getEntity();String content = EntityUtils.toString(httpEntity, "UTF-8");System.out.println(content);}}
}
