如何在Okhttp中更改默认缓存策略？

Cache cache = new Cache(new File("缓存目录"), 缓存大小);
OkHttpClient client = new OkHttpClient.Builder()
        .cache(cache)
        .build();

Interceptor cacheInterceptor = new Interceptor() {
    @Override
    public Response intercept(Chain chain) throws IOException {
        Request request = chain.request();

        // 如果请求不需要缓存，则直接返回响应
        if (!request.header("Cache-Control").contains("no-cache")) {
            Response response = chain.proceed(request);

            // 设置响应的缓存策略
            Response cacheResponse = response.newBuilder()
                    .header("Cache-Control", "max-age=3600") // 设置缓存有效期为1小时
                    .build();

            return cacheResponse;
        }

        return chain.proceed(request);
    }
};

OkHttpClient client = new OkHttpClient.Builder()
        .cache(cache)
        .addInterceptor(cacheInterceptor)
        .build();
