Viewing Lifecycle Rules

If you have any questions during development, post them on the Issues page of GitHub. For details about parameters and usage of each API, see the .

You can call ObsClient.getBucketLifecycle to view lifecycle rules of a bucket. Sample code is as follows:

// 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 ACCESS_KEY_ID and SECRET_ACCESS_KEY_ID.
// Obtain an AK/SK pair on the management console. For details, see https://support.huaweicloud.com/eu/usermanual-ca/ca_01_0003.html.
String ak = System.getenv("ACCESS_KEY_ID");
String sk = System.getenv("SECRET_ACCESS_KEY_ID");
String endPoint = "https://your-endpoint";
// Create an ObsClient instance.
ObsClient obsClient = new ObsClient(ak, sk, endPoint);

LifecycleConfiguration config = obsClient.getBucketLifecycle("bucketname");

for (LifecycleConfiguration.Rule rule : config.getRules()) {
    Log.i("GetBucketLifecycleConfiguration",rule.getId());
    Log.i("GetBucketLifecycleConfiguration",rule.getPrefix());
    for(LifecycleConfiguration.Transition transition : rule.getTransitions()){
        Log.i("GetBucketLifecycleConfiguration",String.valueOf(transition.getDays()));
        Log.i("GetBucketLifecycleConfiguration",transition.getStorageClass());
    }
    Log.i("GetBucketLifecycleConfiguration",rule.getExpiration() != null ? String.valueOf(rule.getExpiration().getDays()) : "");
    for(LifecycleConfiguration.NoncurrentVersionTransition noncurrentVersionTransition : rule.getNoncurrentVersionTransitions()){
        Log.i("GetBucketLifecycleConfiguration",String.valueOf(noncurrentVersionTransition.getDays()));
        Log.i("GetBucketLifecycleConfiguration",noncurrentVersionTransition.getStorageClass());
    }
    Log.i("GetBucketLifecycleConfiguration",rule.getNoncurrentVersionExpiration() != null ?String.valueOf(rule.getNoncurrentVersionExpiration().getDays()) : "");
}
