ListObjectVersions配 AWS SDK 或命令列工具使用

下列程式碼範例會示範如何使用ListObjectVersions

動作範例是大型程式的程式碼摘錄,必須在內容中執行。您可以在下列程式碼範例的內容中看到此動作:

.NET
AWS SDK for .NET
注意

還有更多關於 GitHub。尋找完整範例,並了解如何在AWS 設定和執行程式碼範例儲存庫

using System; using System.Threading.Tasks; using Amazon.S3; using Amazon.S3.Model; /// <summary> /// This example lists the versions of the objects in a version enabled /// Amazon Simple Storage Service (Amazon S3) bucket. /// </summary> public class ListObjectVersions { public static async Task Main() { string bucketName = "doc-example-bucket"; // If the AWS Region where your bucket is defined is different from // the AWS Region where the Amazon S3 bucket is defined, pass the constant // for the AWS Region to the client constructor like this: // var client = new AmazonS3Client(RegionEndpoint.USWest2); IAmazonS3 client = new AmazonS3Client(); await GetObjectListWithAllVersionsAsync(client, bucketName); } /// <summary> /// This method lists all versions of the objects within an Amazon S3 /// version enabled bucket. /// </summary> /// <param name="client">The initialized client object used to call /// ListVersionsAsync.</param> /// <param name="bucketName">The name of the version enabled Amazon S3 bucket /// for which you want to list the versions of the contained objects.</param> public static async Task GetObjectListWithAllVersionsAsync(IAmazonS3 client, string bucketName) { try { // When you instantiate the ListVersionRequest, you can // optionally specify a key name prefix in the request // if you want a list of object versions of a specific object. // For this example we set a small limit in MaxKeys to return // a small list of versions.

  • 如需 API 詳細資訊,請參閱 AWS SDK for .NET API 參考ListObjectVersions中的。

CLI
AWS CLI

下列命令會擷取名為的值區中物件的版本資訊my-bucket

aws s3api list-object-versions --bucket my-bucket --prefix index.html

輸出:
