Setting or Obtaining a Versioning Object ACL

Directly Setting a Versioning Object ACL

You can call ObsClient.SetObjectAcl to pass the version ID (VersionId) to set the ACL for a versioning object. Sample code is as follows:

// Initialize configuration parameters.
ObsConfig config = new ObsConfig();
config.Endpoint = "https://your-endpoint";
// 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 AccessKeyID and SecretAccessKey.
// Obtain an AK/SK pair on the management console. For details, see https://support.huaweicloud.com/eu/usermanual-ca/ca_01_0003.html.
string accessKey= Environment.GetEnvironmentVariable("AccessKeyID", EnvironmentVariableTarget.Machine);
string secretKey= Environment.GetEnvironmentVariable("SecretAccessKey", EnvironmentVariableTarget.Machine);
// Create an instance of ObsClient.
ObsClient client = new ObsClient(accessKey, secretKey, config);
// Set the ACL for a versioning object.
try
{
    SetObjectAclRequest request = new SetObjectAclRequest();
    request.BucketName = "bucketname";
    request.ObjectKey = "objectname";
    request.VersionId = "versionId";
    request.AccessControlList = new AccessControlList();
    Owner owner = new Owner();
    owner.Id = "ownerid";
    request.AccessControlList.Owner = owner;
    Grant item = new Grant();
    item.Permission = PermissionEnum.FullControl;
    item.Grantee = new GroupGrantee(GroupGranteeEnum.AllUsers);
    request.AccessControlList.Grants.Add(item);
    SetObjectAclResponse response = client.SetObjectAcl(request);
    Console.WriteLine("Set object acl response: {0}", response.StatusCode);
}
catch (ObsException ex)
{
    Console.WriteLine("ErrorCode: {0}", ex.ErrorCode);
    Console.WriteLine("ErrorMessage: {0}", ex.ErrorMessage);
}

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 pass the version ID (VersionId) to obtain the ACL of a versioning object. Sample code is as follows:

// Initialize configuration parameters.
ObsConfig config = new ObsConfig();
config.Endpoint = "https://your-endpoint";
// 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 AccessKeyID and SecretAccessKey.
// Obtain an AK/SK pair on the management console. For details, see https://support.huaweicloud.com/eu/usermanual-ca/ca_01_0003.html.
string accessKey= Environment.GetEnvironmentVariable("AccessKeyID", EnvironmentVariableTarget.Machine);
string secretKey= Environment.GetEnvironmentVariable("SecretAccessKey", EnvironmentVariableTarget.Machine);
// Create an instance of ObsClient.
ObsClient client = new ObsClient(accessKey, secretKey, config);
// Obtain the ACL of a versioning object.
try
{
    GetObjectAclRequest request = new GetObjectAclRequest();
    request.BucketName = "bucketname";
    request.ObjectKey = "objectname";
    request.VersionId = "versionId";
    GetObjectAclResponse response = client.GetObjectAcl(request);
    Console.WriteLine("GetObjectAcl grant account: {0}", response.AccessControlList.Grants.Count);
    Console.WriteLine("GetObjectAcl owner id: {0}", response.AccessControlList.Owner.Id);
    foreach (Grant grant in response.AccessControlList.Grants)
    {
        if(grant.Grantee is CanonicalGrantee)
        {
              Console.WriteLine("Grantee id: {0}", (grant.Grantee as CanonicalGrantee).Id);
        }else if(grant.Grantee is GroupGrantee)
        {
              Console.WriteLine("Grantee type: {0}", (grant.Grantee as GroupGrantee).GroupGranteeType);
        }
              Console.WriteLine("Grant permission: {0}", grant.Permission);
        }
    }
}
catch (ObsException ex)
{
    Console.WriteLine("ErrorCode: {0}", ex.ErrorCode);
    Console.WriteLine("ErrorMessage: {0}", ex.ErrorMessage);
}
