Setting or Obtaining a Versioning Object ACL

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

Directly Setting a Versioning Object ACL

You can call ObsClient.setObjectAcl and set the version ID (versionId) to specify the ACL for a versioning object. Sample code is as follows:

String endPoint = "https://your-endpoint";
String ak = "*** Provide your Access Key ***";
String sk = "*** Provide your Secret Key ***";
// Create an instance of ObsClient.
ObsClient obsClient = new ObsClient(ak, sk, endPoint);

// Set the versioning object ACL to public-read by specifying the pre-defined access control policy.
obsClient.setObjectAcl("bucketname", "objectname", AccessControlList.REST_CANNED_PUBLIC_READ, "versionid");

AccessControlList acl = new AccessControlList();
Owner owner = new Owner();
owner.setId("ownerid");
acl.setOwner(owner);
// Grant the READ permission to all users.
acl.grantPermission(GroupGrantee.ALL_USERS, Permission.PERMISSION_READ);
// Set the ACL for a versioning object.
obsClient.setObjectAcl("bucketname", "objectname", acl, "versionid");

The owner or grantee ID needed in the ACL indicates the account ID, which can be viewed on the My Credentials page of OBS Console.

Obtaining a Versioning Object ACL

You can call ObsClient.getObjectAcl to obtain the ACL of a versioning object by specifying the version ID (versionId). Sample code is as follows:

String endPoint = "https://your-endpoint";
String ak = "*** Provide your Access Key ***";
String sk = "*** Provide your Secret Key ***";
// Create an instance of ObsClient.
ObsClient obsClient = new ObsClient(ak, sk, endPoint);

AccessControlList acl = obsClient.getObjectAcl("bucketname", "objectname", "versionid");
System.out.println(acl);
