如何验证亚马逊网络服务sign v4中的支持？

import com.amazonaws.auth.AWS4Signer;
import com.amazonaws.auth.AWSCredentialsProvider;
import com.amazonaws.auth.DefaultAWSCredentialsProviderChain;
import com.amazonaws.http.AWSRequestSigningApacheInterceptor;
import org.apache.http.HttpHost;
import org.apache.http.HttpRequestInterceptor;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import software.amazon.awssdk.http.apache.ApacheHttpClient;

public class AWSAPICallExample {
    public static void main(String[] args) {
        // 创建 AWS4Signer 对象
        AWS4Signer signer = new AWS4Signer();
        signer.setServiceName("s3"); // 设置要访问的 AWS 服务名称
        signer.setRegionName("us-west-2"); // 设置要访问的 AWS 区域

        // 创建 AWSCredentialsProvider 对象
        AWSCredentialsProvider credentialsProvider = new DefaultAWSCredentialsProviderChain();

        // 创建 HttpRequestInterceptor 对象，用于添加签名到请求头
        HttpRequestInterceptor interceptor = new AWSRequestSigningApacheInterceptor(
                "s3", signer, credentialsProvider);

        // 创建 CloseableHttpClient 对象，用于发送请求
        CloseableHttpClient client = HttpClientBuilder.create()
                .addInterceptorLast(interceptor)
                .build();

        // 创建 ApacheHttpClient 对象，用于发送请求
        ApacheHttpClient httpClient = ApacheHttpClient.builder()
                .httpClient(client)
                .build();

        // 发送请求到 AWS 服务端，并处理返回结果
        // ...

        // 关闭 HttpClient
        httpClient.close();
    }
}
