getIamPolicy method

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

Gets the access control policy for an instance resource.

Returns an empty policy if an instance exists but does not have a policy set. Authorization requires spanner.instances.getIamPolicy on resource.

request - The metadata request object.

Request parameters:

resource - REQUIRED: The Cloud Spanner resource for which the policy is being retrieved. The format is projects//instances/ for instance resources and projects//instances//databases/ for database resources. Value must have pattern ^projects/\[^/\]+/instances/\[^/\]+$.

$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? $fields,
}) async {
  final body_ = convert.json.encode(request);
  final queryParams_ = <core.String, core.List<core.String>>{
    if ($fields != null) 'fields': [$fields],
  };

  final url_ = 'v1/' + 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>);
