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 .

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/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 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/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 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);
