如何在Apache AsyncHttpClient中拦截请求？

import org.asynchttpclient.AsyncHttpClient;
import org.asynchttpclient.DefaultAsyncHttpClient;
import org.asynchttpclient.Request;
import org.asynchttpclient.RequestFilter;
import org.asynchttpclient.Response;
import org.asynchttpclient.filter.FilterContext;
import org.asynchttpclient.filter.FilterException;
import org.asynchttpclient.filter.RequestFilterContext;
import org.asynchttpclient.filter.RequestFilterException;

public class RequestInterceptorExample {

    public static void main(String[] args) throws Exception {
        AsyncHttpClient asyncHttpClient = new DefaultAsyncHttpClient();

        asyncHttpClient.setRequestFilter(new RequestFilter() {
            @Override
            public <T> FilterContext<T> filter(FilterContext<T> ctx) throws FilterException {
                Request request = ctx.getRequest();
                // 在这里可以对请求进行修改或者添加自定义逻辑
                System.out.println("拦截到请求：" + request.getUrl());
                return ctx;
            }

            @Override
            public <T> FilterContext<T> filter(FilterContext<T> ctx, RequestFilterContext requestFilterContext) throws RequestFilterException {
                return filter(ctx);
            }
        });

        // 发送请求
        asyncHttpClient.prepareGet("https://www.example.com").execute().toCompletableFuture().join();

        asyncHttpClient.close();
    }
}
