如何将REST调用的选项作为参数添加到头部？

import java.io.IOException;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.HashMap;
import java.util.Map;

public class RestCallExample {
    public static void main(String[] args) throws IOException {
        // 创建URL对象
        URL url = new URL("http://example.com/api/endpoint");

        // 打开连接
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();

        // 设置请求方法
        connection.setRequestMethod("GET");

        // 创建参数Map
        Map<String, String> options = new HashMap<>();
        options.put("option1", "value1");
        options.put("option2", "value2");

        // 将选项参数添加到头部
        for (Map.Entry<String, String> entry : options.entrySet()) {
            connection.setRequestProperty(entry.getKey(), entry.getValue());
        }

        // 发送请求
        int responseCode = connection.getResponseCode();

        // 处理响应结果
        // ...

        // 关闭连接
        connection.disconnect();
    }
}
