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); }
}
