request method

@override Future<HttpResponseSpec> request(MapScenarioWorld world, HttpRequestSpec request)

Executes a logical request.

Implementation

@override
Future<HttpResponseSpec> request(
  MapScenarioWorld world,
  HttpRequestSpec request,
) async {
  final path = endpoints[request.endpointId];
  if (path == null) {
    throw StateError('Unknown logical endpoint: ${request.endpointId}');
  }
  final uri = baseUri.resolve(path);
  final stopwatch = Stopwatch()..start();
  final httpRequest = await client.openUrl(request.method, uri);
  httpRequest.headers.contentType = ContentType.json;
  request.headers.forEach(httpRequest.headers.set);
  if (request.body != null) httpRequest.write(jsonEncode(request.body));
  final response = await httpRequest.close();
  final bodyText = await utf8.decoder.bind(response).join();
  stopwatch.stop();
  Object? body;
  if (bodyText.isNotEmpty) {
    try {
      body = jsonDecode(bodyText);
    } on FormatException {
      body = bodyText;
    }
  }
  return HttpResponseSpec(
    statusCode: response.statusCode,
    body: body,
    latency: stopwatch.elapsed,
  );
