在亚马逊网络服务S3(v2.4.4)中,要检索并删除特定文件夹中的文件列表,可以通过以下步骤完成:
import software.amazon.awssdk.services.s3.S3Client;
import software.amazon.awssdk.services.s3.model.ListObjectsV2Request;
import software.amazon.awssdk.services.s3.model.ListObjectsV2Response;
import software.amazon.awssdk.services.s3.model.S3Object;
public class S3Example {
public static void main(String[] args) {
S3Client s3Client = S3Client.create();
ListObjectsV2Request listObjectsRequest = ListObjectsV2Request.builder()
.bucket("my-bucket")
.prefix("my-folder/")
.build();
ListObjectsV2Response listObjectsResponse = s3Client.listObjectsV2(listObjectsRequest);
for (S3Object s3Object : listObjectsResponse.contents()) {
System.out.println("File: " + s3Object.key());
}
}
}
import software.amazon.awssdk.services.s3.S3Client;
import software.amazon.awssdk.services.s3.model.DeleteObjectRequest;
public class S3Example {
public static void main(String[] args) {
S3Client s3Client = S3Client.create();
DeleteObjectRequest deleteObjectRequest = DeleteObjectRequest.builder()
.bucket("my-bucket")
.key("my-folder/file.txt")
.build();
s3Client.deleteObject(deleteObjectRequest);
System.out.println("File deleted successfully.");
}
}
