generateResponse function

Response generateResponse(Request request, NetworkObject object, { int status = HttpStatus.ok, String defaultAcceptHeader = '*/*)', })

Allow you to easily generate response based on accept header object is the object that will be serialized you can specify the status code by changing status defaultAcceptHeader is used only if the request doesn't have accept header

Implementation

Response generateResponse(final Request request, final NetworkObject object,
    {final int status = HttpStatus.ok,
    final String defaultAcceptHeader = '*/*)'}) {
  final requestAccept =
      request.headers[HttpHeaders.acceptHeader] ?? defaultAcceptHeader;
  final acceptAll = requestAccept.contains('*/*');

  if (acceptAll) {
    return switch (object) {
      NetworkObjectToJson _ => _jsonResponse(status, object),
      NetworkObjectToXml _ => _xmlResponse(status, object),
    };
  }

  final splitRequestAccept = requestAccept.split(';');
  final filteredAccept =
      splitRequestAccept.where((element) => !element.contains('=')).toList();
  final acceptableHeader =
      filteredAccept.map((e) => ContentType.parse(e)).toList();

  for (final acceptHeader in acceptableHeader) {
    if (acceptHeader.primaryType == 'application' &&
        acceptHeader.subType == 'json' &&
        object is NetworkObjectToJson) {
      return _jsonResponse(status, object);
    } else if (acceptHeader.primaryType == 'application' &&
        acceptHeader.subType == 'xml' &&
        object is NetworkObjectToXml) {
      return _xmlResponse(status, object);
    }
  }

  return Response.badRequest();
