创建HttpGetTest.java
package crawler.test; 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 HttpGetTest { public static void main(String[] args) { //创建HttpClient对象 CloseableHttpClient httpClient = HttpClients.createDefault(); //创建HttpGet对象，设置url访问地址 HttpGet httpGet = new HttpGet("https://www.baidu.com"); CloseableHttpResponse response = null; try { //使用HttpClient发起请求，获取response response = httpClient.execute(httpGet); if (response.getStatusLine().getStatusCode() == 200) { String content = EntityUtils.toString(response.getEntity(), "utf8"); // 输出content的长度来表示程序执行成功 System.out.println(content.length()); } } catch (IOException e) { e.printStackTrace(); } finally { // 关闭response和httpClient try { response.close(); } catch (IOException e) { e.printStackTrace(); } try { httpClient.close(); } catch (IOException e) { e.printStackTrace(); } } } } package crawler.te
