getIamPolicy method
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>);
