如何通过okhttp3获取http响应头，并决定是否获取响应体

dependencies {
    implementation 'com.squareup.okhttp3:okhttp:版本号'
}

import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;

public class Example {
    public static void main(String[] args) {
        OkHttpClient client = new OkHttpClient();

        // 创建一个请求对象
        Request request = new Request.Builder()
                .url("http://www.example.com")
                .build();

        try {
            // 发送请求并获取响应
            Response response = client.newCall(request).execute();

            // 获取响应头
            String headers = response.headers().toString();
            System.out.println("Response Headers: " + headers);

            // 判断是否需要获取响应体
            boolean shouldGetResponseBody = true;
            if (shouldGetResponseBody) {
                String responseBody = response.body().string();
                System.out.println("Response Body: " + responseBody);
            }

            // 关闭响应
            response.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
