Header、Cookie

package com.test.demo;

import java.io.IOException;

import org.apache.http.Header;

public class Headers {

       public static void main(String[] args) throws ClientProtocolException, IOException {

              // 创建CloseableHttpClient对象
              CloseableHttpClient httpclient = HttpClients.createDefault();
              // 创建HttpPost对象
              HttpPost httpPost = new HttpPost("http://localhost:8083/header");

              // 设置请求头信息
              httpPost.setHeader("content-type", "application/json");
              httpPost.setHeader("Self-Header", "MySelfHeader");
              // 添加Json参数

              httpclient.close();

       }

}

2、运行结果：

2、Cookie

1、创建Cookies类。

创建CookieStore对象，创建BasicClientCookie对象，添加Cookie。

脚本代码：

package com.test.demo;

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

import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.CookieStore;
import org.apache.http.client.config.RequestConfig;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.cookie.Cookie;
import org.apache.http.entity.StringEntity;
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.impl.cookie.BasicClientCookie;
import org.apache.http.util.EntityUtils;
import org.json.JSONObject;

/**
 * Cookie
 *
 * @author wangmcn
 *
 */
public class Cookies {

       public static void main(String[] args) throws ClientProtocolException, IOException {

              // 创建CookieStore对象
              CookieStore cookieStore = new BasicCookieStore();
             
              // 创建BasicClientCookie对象，添加Cookie
              BasicClientCookie cookie = new BasicClientCookie("login", "true");
              cookie.setVersion(0);
              cookie.setDomain("localhost");
              cookie.setPath("/");
              cookieStore.addCookie(cookie);

              // 创建CloseableHttpClient对象
              CloseableHttpClient httpclient = HttpClients.custom()
                            // 设置Cookie
                            .setDefaultCookieStore(cookieStore)
                            .build();
              // 创建HttpPost对象
              HttpPost httpPost = new HttpPost("http://localhost:8083/cookie");
              // 设置超时
              RequestConfig requestConfig = RequestConfig.custom()
                            .setConnectTimeout(15000) // 设置连接超时时间，单位毫秒
                            .setSocketTimeout(15000) // 请求获取数据的超时时间，单位毫秒
                            .setConnectionRequestTimeout(15000) // 设置从connect Manager获取Connection超时时间，单位毫秒
                            .build();
              httpPost.setConfig(requestConfig);
              // 设置请求头信息
              httpPost.setHeader("content-type", "application/json");
              // 添加Json参数
              JSONObject param = new JSONObject();
              param.put("username", "admin");
              param.put("password", "123456");
              // 将参数信息添加到方法中
              StringEntity entity = new StringEntity(param.toString(), "utf-8");
              httpPost.setEntity(entity);
              // 执行Post请求
              CloseableHttpResponse response = httpclient.execute(httpPost);
              // 获取响应状态
              System.out.println("获取响应状态: " + response.getStatusLine().getStatusCode());
              // 获取响应结果
              String result = EntityUtils.toString(response.getEntity(), "utf-8");
              // 将返回的响应结果字符串转化成为Json对象
              JSONObject resultJson = new JSONObject(result);
              // 获取网页源码
              System.out.println("获取网页源码：" + resultJson);

              // 获取Cookie
              ListcookieList = cookieStore.getCookies();
              for (Cookie cookies : cookieList) {
                     System.out.println("Cookie: " + cookies.getName() + "; " + cookies.getValue());
              }

              // 关闭流和释放系统资源
              response.close();
              // 关闭客户端
              httpclient.close();

       }
