如何检查数据是否已在缓存OkHttp中

import okhttp3.Cache;
import okhttp3.CacheControl;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;

import java.io.IOException;

public class OkHttpCacheExample {
    public static void main(String[] args) {
        // 创建OkHttpClient对象
        OkHttpClient client = new OkHttpClient.Builder()
                .cache(new Cache("cache-directory", 10 * 1024 * 1024)) // 设置缓存目录和大小
                .build();

        // 创建Request对象
        Request request = new Request.Builder()
                .url("https://example.com/api/data")
                .build();

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

            // 检查缓存状态
            if (response.cacheResponse() != null) {
                System.out.println("数据已在缓存中");
            } else {
                System.out.println("数据不在缓存中");
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
