Deleting Versioning Objects

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 API Reference

Deleting a Single Versioning Object

You can call ObsClient.deleteObject to pass the version ID (versionId) to delete a versioning object. 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/intl/en-us/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 instance of ObsClient.
ObsClient obsClient = new ObsClient(ak, sk, endPoint);
obsClient.deleteObject("bucketname", "objectname", "versionid");

Deleting Versioning Objects in a Batch

You can call ObsClient.deleteObjects to pass the version ID (versionId) of each to-be-deleted versioning object to delete them at a time. 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/intl/en-us/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 instance of ObsClient.
ObsClient obsClient = new ObsClient(ak, sk, endPoint);

DeleteObjectsRequest request = new DeleteObjectsRequest("bucketname");
request.setQuiet(false);
List<KeyAndVersion> toDelete = new ArrayList<KeyAndVersion>();
toDelete.add(new KeyAndVersion("objectname1", "versionid1"));
toDelete.add(new KeyAndVersion("objectname2", "versionid2"));
toDelete.add(new KeyAndVersion("objectname3", "versionid3"));
request.setKeyAndVersions(toDelete.toArray(new KeyAndVersion[toDelete.size()]));
DeleteObjectsResult result = obsClient.deleteObjects(request);

Log.i("DeleteObjects","\t" + result.getDeletedObjectResults());
Log.i("DeleteObjects","\t" + result.getErrorResults());
