        /// 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 ]

**Amazon CLI**  
以下命令检索名为 `amzn-s3-demo-bucket` 的存储桶的生命周期配置：  

```
aws s3api get-bucket-lifecycle-configuration --bucket {{amzn-s3-demo-bucket}}
```
输出：  

```
