preview method

Future<RoutersPreviewResponse> preview(Router request, String project, String region, String router, { String? $fields, })

Preview fields auto-generated during router create and update operations.

Calling this method does NOT create or update the router.

request - The metadata request object.

Request parameters:

project - Project ID for this request. Value must have pattern (?:(?:\[-a-z0-9\]{1,63}\.)*(?:\[a-z\](?:\[-a-z0-9\]{0,61}\[a-z0-9\])?):)?(?:\[0-9\]{1,19}|(?:\[a-z0-9\](?:\[-a-z0-9\]{0,61}\[a-z0-9\])?)).

region - Name of the region for this request. Value must have pattern \[a-z\](?:\[-a-z0-9\]{0,61}\[a-z0-9\])?.

router - Name of the Router resource to query. Value must have pattern \[a-z\](?:\[-a-z0-9\]{0,61}\[a-z0-9\])?|\[1-9\]\[0-9\]{0,19}.

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

Completes with a RoutersPreviewResponse.

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<RoutersPreviewResponse> preview(
  Router request,
  core.String project,
  core.String region,
  core.String router, {
  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_ = 'projects/' +
      commons.escapeVariable('$project') +
      '/regions/' +
      commons.escapeVariable('$region') +
      '/routers/' +
      commons.escapeVariable('$router') +
      '/preview';

  final response_ = await _requester.request(
    url_,
    'POST',
    body: body_,
    queryParams: queryParams_,
  );
  return RoutersPreviewResponse.fromJson(
      response_ as core.Map<core.String, core.dynamic>);
