How to query the ACL of a bucket - Object Storage Service

A bucket is a container used to store objects in Object Storage Service (OSS). All objects in OSS are stored in buckets. This topic describes how to query the access control list (ACL) of a bucket.

The following table describes the bucket ACLs.

ACL	Description	Value
Private	Only the bucket owner and authorized users have read and write permissions on objects in the bucket. Other users cannot access objects in the bucket.	private
Public-read	Only the bucket owner and authorized users have read and write permissions on objects in the bucket. Other users have only read permissions on objects in the bucket. Exercise caution when you set the bucket ACL to this value.	public-read
Public-read-write	All users have read and write permissions on objects in the bucket. Exercise caution when you set the bucket ACL to this value.	public-read-write

Examples

The following sample code provides an example on how to query the ACL of a bucket:

GetBucketACLRequest getBucketACLRequest = new GetBucketACLRequest("bucketName");

// Query the ACL of the bucket. 
OSSAsyncTask getBucketAclTask = oss.asyncGetBucketACL(getBucketACLRequest, new OSSCompletedCallback<GetBucketACLRequest, GetBucketACLResult>() {
    @Override
    public void onSuccess(GetBucketACLRequest request, GetBucketACLResult result) {
        Log.d("asyncGetBucketACL", "Success!");
        Log.d("BucketAcl", result.getBucketACL());
        Log.d("Owner", result.getBucketOwner());
        Log.d("ID", result.getBucketOwnerID());
    }
    @Override
    public void onFailure(GetBucketACLRequest request, ClientException clientException, ServiceException serviceException) {
        // Handle request exceptions. 
        if (clientException != null) {
            // Handle client exceptions, such as network exceptions. 
            clientException.printStackTrace();
        }
        if (serviceException != null) {
            // Handle service exceptions. 
            Log.e("ErrorCode", serviceException.getErrorCode());
            Log.e("RequestId", serviceException.getRequestId());
            Log.e("HostId", serviceException.getHostId());
            Log.e("RawMessage", serviceException.getRawMessage());
        }
    }
});
