beginTransaction method

Future<BeginTransactionResponse> beginTransaction(BeginTransactionRequest request, String projectId, { String? $fields, })

Begins a new transaction.

request - The metadata request object.

Request parameters:

projectId - Required. The ID of the project against which to make the request.

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

Completes with a BeginTransactionResponse.

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<BeginTransactionResponse> beginTransaction(
  BeginTransactionRequest request,
  core.String projectId, {
  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/projects/' +
      commons.escapeVariable('$projectId') +
      ':beginTransaction';

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