send method

Future<TestResponse> send(String method, String path, { Object? body, Map<String, String>? headers, })

Send a request. path can have a query, eg. /users?page=2.

A String or List<int> body is sent as it is. Any other body (eg. a Map) is sent as JSON, with Content-Type: application/json. Redirects are not followed, so you can check them.

Implementation

Future<TestResponse> send(
  String method,
  String path, {
  Object? body,
  Map<String, String>? headers,
}) async {
  HttpClientRequest request = await _http.openUrl(
    method,
    baseUri.resolve(path),
  );
  request.followRedirects = false;
  List<int>? bytes;
  if (body is List<int>) {
    bytes = body;
  } else if (body is String) {
    bytes = utf8.encode(body);
  } else if (body != null) {
    bytes = utf8.encode(jsonEncode(body));
    request.headers.contentType = ContentType.json;
  }
  Map<String, String> all = <String, String>{...this.headers, ...?headers};
  Map<String, String>? jar = _jar;
  if (jar != null) _addJar(jar, method, all);
  for (MapEntry<String, String> header in all.entries) {
    request.headers.set(header.key, header.value);
  }
  if (bytes != null) {
    request.contentLength = bytes.length;
    request.add(bytes);
  }
  HttpClientResponse response = await request.close();
  BytesBuilder data = BytesBuilder(copy: false);
  await for (List<int> chunk in response) {
    data.add(chunk);
  }
  if (jar != null) _keep(jar, response.cookies);
  Map<String, String> found = <String, String>{};
  response.headers.forEach((String name, List<String> values) {
    found[name.toLowerCase()] = values.join(', ');
  });
  return TestResponse(
    response.statusCode,
    found,
    data.takeBytes(),
    cookies: <String, String>{
      for (Cookie cookie in response.cookies) cookie.name: cookie.value,
    },
  );
}
