使用 AWS SDK 获取 Amazon S3 存储桶的生命周期配置

以下代码示例显示如何获取 S3 存储桶的生命周期配置。

.NET
AWS SDK for .NET
注意

/// <summary> /// Returns a configuration object for the supplied bucket name. /// </summary> /// <param name="client">The S3 client object used to call /// the GetLifecycleConfigurationAsync method.</param> /// <param name="bucketName">The name of the S3 bucket for which a /// configuration will be created.</param> /// <returns>Returns a new LifecycleConfiguration object.</returns> public static async Task<LifecycleConfiguration> RetrieveLifecycleConfigAsync(IAmazonS3 client, string bucketName) { var request = new GetLifecycleConfigurationRequest() { BucketName = bucketName, }; var response = await client.GetLifecycleConfigurationAsync(request); var configuration = response.Configuration; return configuration; }
CLI
AWS CLI

以下命令检索名为 my-bucket 的存储桶的生命周期配置:

aws s3api get-bucket-lifecycle-configuration --bucket my-bucket

输出:

{ "Rules": [ { "ID": "Move rotated logs to Glacier", "Prefix": "rotated/", "Status": "Enabled", "Transitions": [ { "Date": "2015-11-10T00:00:00.000Z", "StorageClass": "GLACIER" } ] }, { "Status": "Enabled", "Prefix": "", "NoncurrentVersionTransitions": [ { "NoncurrentDays": 0, "StorageClass": "GLACIER" } ], "ID": "Move old versions to Glacier" } ] }
