Viewing Lifecycle Rules

You can call ObsClient.GetBucketLifecycle to view lifecycle rules.

This example views the lifecycle configuration of bucket bucketname.

The example code is as follows:

// Initialize configuration parameters.
ObsConfig config = new ObsConfig();
config.Endpoint = "https://your-endpoint";
// Hard-coded or plaintext AK/SK are risky. For security purposes, encrypt your AK/SK and store them in the configuration file or environment variables. In this example, the AK/SK are stored in environment variables for identity authentication. Before running this example, configure environment variables AccessKeyID and SecretAccessKey.
// Obtain an AK/SK pair on the management console. For details, see https://support.huaweicloud.com/eu/usermanual-ca/ca_01_0003.html.
string accessKey= Environment.GetEnvironmentVariable("AccessKeyID", EnvironmentVariableTarget.Machine);
string secretKey= Environment.GetEnvironmentVariable("SecretAccessKey", EnvironmentVariableTarget.Machine);
// Create an instance of ObsClient.
ObsClient client = new ObsClient(accessKey, secretKey, config);
// View the bucket lifecycle.
try
{
    GetBucketLifecycleRequest request = new GetBucketLifecycleRequest();
    request.BucketName = "bucketname";
    GetBucketLifecycleResponse response = client.GetBucketLifecycle(request);
    foreach (LifecycleRule lifecycleRule in response.Configuration.Rules)
    {
        Console.WriteLine("Lifecycle rule id: {0}", lifecycleRule.Id);
        Console.WriteLine("Lifecycle rule prefix: {0}", lifecycleRule.Prefix);
        Console.WriteLine("Lifecycle rule status: {0}", lifecycleRule.Status);
        if (null != lifecycleRule.Expiration)
        {
            Console.WriteLine("expiration days: {0}", lifecycleRule.Expiration.Days);
        }
        if (null != lifecycleRule.NoncurrentVersionExpiration)
        {
            Console.WriteLine("NoncurrentVersionExpiration NoncurrentDays: {0}", lifecycleRule.NoncurrentVersionExpiration.NoncurrentDays);
        }
        foreach (Transition transition in lifecycleRule.Transitions)
        {
            Console.WriteLine("Transition Days : {0}", transition.Days);
            Console.WriteLine("Transition StorageClass : {0}", transition.StorageClass);
        }
        foreach (NoncurrentVersionTransition noncurrentVersionTransition in lifecycleRule.NoncurrentVersionTransitions)
        {
            Console.WriteLine("NoncurrentVersionTransition NoncurrentDays: {0}", noncurrentVersionTransition.NoncurrentDays);
            Console.WriteLine("NoncurrentVersionTransition StorageClass : {0}", noncurrentVersionTransition.StorageClass);
        }
        Console.WriteLine("Get bucket lifecycle response: {0}", response.StatusCode);
    }
