httpclient就是一个模拟 发送http请求的一个工具。
首先在pom.xml文件里面添加工具类
<dependencies>
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.1.2</version>
</dependency>
</dependencies>
新建一个类,写入代码:
package com.course.httpclient.demo; import org.apache.http.HttpResponse; import org.apache.http.client.HttpClient; import org.apache.http.client.methods.HttpGet; import org.apache.http.impl.client.DefaultHttpClient; import org.apache.http.util.EntityUtils; import org.testng.Assert; import org.testng.annotations.Test; import java.io.IOException; public class MyHttpClient { @Test public void test1() throws IOException { //定义一个result 用来存放我们的结果 String result;
//定义一个发送get请求的对象 HttpGet get = new HttpGet("http://www.baidu.com"); //定义一个 client 用来执行get方法 HttpClient client = new DefaultHttpClient();
//定义一个 response,用来接收结果,类型是HttpResponse HttpResponse response = client.execute(get); //getEntity()获取到响应的全体信息,返回的是HttpEntity,用EntityUtils工具把结果转换成字符串
result = EntityUtils.toString(response.getEntity(),"utf-8"); Assert.assertTrue(result.contains("STATUS OK")); //System.out.println(result); } }
