如何创建cookie并在HttpURLConnection中使用它？

import java.net.HttpURLConnection;
import java.net.URL;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.CookieHandler;
import java.net.CookieManager;
import java.net.CookiePolicy;
import java.net.CookieStore;
import java.net.HttpCookie;

CookieManager cookieManager = new CookieManager();
cookieManager.setCookiePolicy(CookiePolicy.ACCEPT_ALL);
CookieHandler.setDefault(cookieManager);

URL url = new URL("http://example.com");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();

connection.setRequestProperty("Cookie", "key1=value1; key2=value2");

InputStream inputStream = connection.getInputStream();
// 读取响应内容
inputStream.close();

// 获取CookieStore
CookieStore cookieStore = cookieManager.getCookieStore();
// 获取所有的Cookie
List<HttpCookie> cookies = cookieStore.getCookies();
