使用maven,在xml中引用
<!-- https://mvnrepository.com/artifact/org.apache.httpcomponents/httpclient -->
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.5.2</version>
</dependency>
第一个demo
第一个.java文件
package com.httpclient.demo;
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.HttpClientBuilder;
import org.apache.http.util.EntityUtils;
import org.testng.annotations.Test;
import java.io.IOException;
public class HttpClientDemo {
@Test
public void test01() {
//创建get请求
String uri = "https://www.baidu.com";
HttpGet get = new HttpGet(uri);
//获取http客户端
CloseableHttpClient client = HttpClientBuilder.create().build();
//响应模型
CloseableHttpResponse response = null;
try {
//由http客户端,发送get请求
response = client.execute(get);
//从响应中,获取响应实体
HttpEntity respEntity = response.getEntity();
String result = EntityUtils.toString(respEntity, "utf-8");
System.out.println(result);
} catch (IOException e) {
e.printStackTrace();
}
}
}
执行结果:
将配置文件进行优化
在项目resources目录下,建一个application.properties文件,将自己需要用的常量可以放在配置文件中
在测试类中,将配置文件引入:
@BeforeTest public void beforeClass() { //将配置文件application.properties中,加载进来 bundle = ResourceBundle.getBundle("application", Locale.CHINA); url = bundle.getString("test.url"); }
字符编码:Locale.CHINA,将配置文件中的一些中文进行兼容
这个url这个变量,定义为全局变量,先在@BeforeTest中引入,然后url这个变量就被赋值了。下面就可以继续引用了
获取Cookie
下面?这个是另一个博主写的:https://segmentfault.com/a/1190000011142669
获取响应的状态码:
//获取响应的状态码,直接在响应response中获取 int statusCode = response.getStatusLine().getStatusCode(); System.out.println("状态码 :" + statusCode);
