publishFunction method

Future<PublishFunctionResult> publishFunction({ required String ifMatch, required String name, })

Publishes a CloudFront function by copying the function code from the DEVELOPMENT stage to LIVE. This automatically updates all cache behaviors that are using this function to use the newly published copy in the LIVE stage.

When a function is published to the LIVE stage, you can attach the function to a distribution's cache behavior, using the function's Amazon Resource Name (ARN).

To publish a function, you must provide the function's name and version (ETag value). To get these values, you can use ListFunctions and DescribeFunction.

May throw InvalidArgument. May throw InvalidIfMatchVersion. May throw NoSuchFunctionExists. May throw PreconditionFailed. May throw UnsupportedOperation.

Parameter ifMatch : The current version (ETag value) of the function that you are publishing, which you can get using DescribeFunction.

Parameter name : The name of the function that you are publishing.

Implementation

Future<PublishFunctionResult> publishFunction({
  required String ifMatch,
  required String name,
}) async {
  final headers = <String, String>{
    'If-Match': ifMatch.toString(),
  };
  final $result = await _protocol.sendRaw(
    method: 'POST',
    requestUri: '/2020-05-31/function/${Uri.encodeComponent(name)}/publish',
    headers: headers,
    exceptionFnMap: _exceptionFns,
  );
  final $elem = await _s.xmlFromResponse($result);
  return PublishFunctionResult(
    functionSummary: FunctionSummary.fromXml($elem),
  );
}
