getRecommendations method

Future<GetRecommendationsResponse> getRecommendations({ required String assistantId, required String sessionId, int? maxResults, int? waitTimeSeconds, })

Retrieves recommendations for the specified session. To avoid retrieving the same recommendations in subsequent calls, use NotifyRecommendationsReceived. This API supports long-polling behavior with the waitTimeSeconds parameter. Short poll is the default behavior and only returns recommendations already available. To perform a manual query against an assistant, use QueryAssistant.

May throw AccessDeniedException. May throw ResourceNotFoundException. May throw ValidationException.

Parameter assistantId : The identifier of the Wisdom assistant. Can be either the ID or the ARN. URLs cannot contain the ARN.

Parameter sessionId : The identifier of the session. Can be either the ID or the ARN. URLs cannot contain the ARN.

Parameter maxResults : The maximum number of results to return per page.

Parameter waitTimeSeconds : The duration (in seconds) for which the call waits for a recommendation to be made available before returning. If a recommendation is available, the call returns sooner than WaitTimeSeconds. If no messages are available and the wait time expires, the call returns successfully with an empty list.

Implementation

Future<GetRecommendationsResponse> getRecommendations({
  required String assistantId,
  required String sessionId,
  int? maxResults,
  int? waitTimeSeconds,
}) async {
  _s.validateNumRange(
    'maxResults',
    maxResults,
    1,
    100,
  );
  _s.validateNumRange(
    'waitTimeSeconds',
    waitTimeSeconds,
    0,
    20,
  );
  final $query = <String, List<String>>{
    if (maxResults != null) 'maxResults': [maxResults.toString()],
    if (waitTimeSeconds != null)
      'waitTimeSeconds': [waitTimeSeconds.toString()],
  };
  final response = await _protocol.send(
    payload: null,
    method: 'GET',
    requestUri:
        '/assistants/${Uri.encodeComponent(assistantId)}/sessions/${Uri.encodeComponent(sessionId)}/recommendations',
    queryParams: $query,
    exceptionFnMap: _exceptionFns,
  );
  return GetRecommendationsResponse.fromJson(response);
