如何使用C#拉取S3存储桶中对象的元数据？

using Amazon;
using Amazon.S3;
using Amazon.S3.Model;

public class S3MetadataFetcher
{
    private const string accessKey = "YOUR_ACCESS_KEY";
    private const string secretKey = "YOUR_SECRET_KEY";
    private const string bucketName = "YOUR_BUCKET_NAME";
    private const string objectKey = "YOUR_OBJECT_KEY";

    public static void Main(string[] args)
    {
        var config = new AmazonS3Config
        {
            RegionEndpoint = RegionEndpoint.USWest2, // 设置S3存储桶所在的区域
            ServiceURL = "https://s3.amazonaws.com" // 设置S3服务的URL
        };

        using (var client = new AmazonS3Client(accessKey, secretKey, config))
        {
            var request = new GetObjectMetadataRequest
            {
                BucketName = bucketName,
                Key = objectKey
            };

            var response = client.GetObjectMetadata(request);

            // 输出对象的元数据
            Console.WriteLine("Object Metadata:");
            foreach (var metadata in response.Metadata)
            {
                Console.WriteLine($"{metadata.Key}: {metadata.Value}");
            }
        }
    }
}
