getIamPolicy method

Future<Policy> getIamPolicy(GetIamPolicyRequest request, String resource, { String? $fields, })

Gets the access control policy for a resource.

A NOT_FOUND error is returned if the resource does not exist. An empty policy is returned if the resource exists but does not have a policy set on it. Supported resources are: - Tag templates. - Entries. - Entry groups. Note, this method cannot be used to manage policies for BigQuery, Pub/Sub and any external Google Cloud Platform resources synced to Data Catalog. Callers must have following Google IAM permission - datacatalog.tagTemplates.getIamPolicy to get policies on tag templates.

• datacatalog.entries.getIamPolicy to get policies on entries. - datacatalog.entryGroups.getIamPolicy to get policies on entry groups.

request - The metadata request object.

Request parameters:

resource - REQUIRED: The resource for which the policy is being requested. See the operation documentation for the appropriate value for this field. Value must have pattern ^projects/\[^/\]+/locations/\[^/\]+/entryGroups/\[^/\]+/entries/\[^/\]+$.

$fields - Selector specifying which fields to include in a partial response.

Completes with a Policy.

Completes with a commons.ApiRequestError if the API endpoint returned an error.

If the used http.Client completes with an error when making a REST call, this method will complete with the same error.

Implementation

async.Future<Policy> getIamPolicy(
  GetIamPolicyRequest request,
  core.String resource, {
  core.String? $fields,
}) async {
  final _body = convert.json.encode(request.toJson());
  final _queryParams = <core.String, core.List<core.String>>{
    if ($fields != null) 'fields': [$fields],
  };

  final _url =
      'v1beta1/' + core.Uri.encodeFull('$resource') + ':getIamPolicy';

  final _response = await _requester.request(
    _url,
    'POST',
    body: _body,
    queryParams: _queryParams,
  );
  return Policy.fromJson(_response as core.Map<core.String, core.dynamic>);
