Copying a Versioning Object

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.copyObject to pass the version ID (versionId) to copy 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);

CopyObjectRequest request = new CopyObjectRequest();
request.setSourceBucketName("sourebucketname");
request.setSourceObjectKey("sourceobjectname");
// Set the version ID of the object to be copied.
request.setVersionId("versionid");
request.setDestinationBucketName("destbucketname");
request.setDestinationObjectKey("destobjectname");
obsClient.copyObject(request);
