CloseableHttpClient学习笔记(获取cookies+携带获取的cookies访问get接口)

注意： 本文的分享是基于https://blog.csdn.net/lt326030434/article/details/80449856，感谢原作者的分享~
分享这篇博客是因为原博客里的DefaultHttpClient is deprecated（httpclient4.3以后），所以此处是一个修改过后的方法，供大家参考.

1.首先配置好测试用的mock接口
我们要做的是从/getcookies接口中获取”login”:”true”的cookies信息，然后携带该信息去访问/get/with/cookies接口

2.全局变量配置url信息

3. 实现代码

package com.gracie.httpclient.cookies;

import org.apache.http.client.CookieStore;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.cookie.Cookie;
import org.apache.http.impl.client.BasicCookieStore;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;

import java.io.IOException;
import java.util.List;
import java.util.Locale;
import java.util.ResourceBundle;

public class MyCookiesForGet {
private String url;
private ResourceBundle bundle;

//用来存储cookies信息的变量
private CookieStore store;

//读取配置文件里的内容
@BeforeTest
public void beforeTest(){
bundle=ResourceBundle.getBundle(“application”, Locale.CHINA);
url=bundle.getString(“test.url”);
}

@Test
public void testGetCoookies() throws IOException{

    String result;

    //从配置文件中拼接测试的URL
    String uri=bundle.getString("getCookies.uri");
    String testUrl=this.url+uri;

    // 获取cookies信息
    this.store= new BasicCookieStore();
    CloseableHttpClient httpclient = HttpClients.custom().setDefaultCookieStore(store).build();

    //测试逻辑
    HttpGet httpget=new HttpGet(testUrl);
    CloseableHttpResponse response2 = httpclient.execute(httpget);

    //打印返回值
    result = EntityUtils.toString(response2.getEntity());
    System.out.println(result);

    //读取cookie信息
    List cookielist = store.getCookies();
    for(Cookie cookie: cookielist){
        String name=cookie.getName();
        String value=cookie.getValue();
        System.out.println("cookie name =" + name);
        System.out.println("Cookie name=" + value);
    }



}

@Test(dependsOnMethods = {"testGetCoookies"})
public void testGetwithCookies() throws IOException {

    String uri=bundle.getString("test.get.with.cookies");
    String testUrl=this.url+uri;


    CloseableHttpClient httpclient = HttpClients.custom().setDefaultCookieStore(this.store).build();

    HttpGet httpget=new HttpGet(testUrl);

    CloseableHttpResponse response3 = httpclient.execute(httpget);
    int statusCode = response3.getStatusLine().getStatusCode();
    System.out.println("statusCode = "+ statusCode);

    if (statusCode==200){
        String result = EntityUtils.toString(response3.getEntity(),"utf-8"); System.out.println(result);
    } else {
        System.out.println("访问/get/with/cookies接口失败");
    }




}

}

4. 测试结果

5. 如果cookie的value变一下，变成false，得到的结果将是400：
