getFunction method

Future<GetFunctionResult> getFunction({ required String name, FunctionStage? stage, })

Gets the code of a CloudFront function. To get configuration information and metadata about a function, use DescribeFunction.

To get a function's code, you must provide the function's name and stage. To get these values, you can use ListFunctions.

May throw NoSuchFunctionExists. May throw UnsupportedOperation.

Parameter name : The name of the function whose code you are getting.

Parameter stage : The function's stage, either DEVELOPMENT or LIVE.

Implementation

Future<GetFunctionResult> getFunction({
  required String name,
  FunctionStage? stage,
}) async {
  final $query = <String, List<String>>{
    if (stage != null) 'Stage': [stage.value],
  };
  final $result = await _protocol.sendRaw(
    method: 'GET',
    requestUri: '/2020-05-31/function/${Uri.encodeComponent(name)}',
    queryParams: $query,
    exceptionFnMap: _exceptionFns,
  );
  return GetFunctionResult(
    functionCode: await $result.stream.toBytes(),
    contentType: _s.extractHeaderStringValue($result.headers, 'Content-Type'),
    eTag: _s.extractHeaderStringValue($result.headers, 'ETag'),
  );
}
