postRoomKeysVersion method

Future<String> postRoomKeysVersion(BackupAlgorithm algorithm, Map<String, Object?> authData)

Creates a new backup.

algorithm The algorithm used for storing backups.

authData Algorithm-dependent data. See the documentation for the backup algorithms in Server-side key backups for more information on the expected format of the data.

returns version: The backup version. This is an opaque string.

Implementation

Future<String> postRoomKeysVersion(
  BackupAlgorithm algorithm,
  Map<String, Object?> authData,
) async {
  final requestUri = Uri(path: '_matrix/client/v3/room_keys/version');
  final request = Request('POST', baseUri!.resolveUri(requestUri));
  request.headers['authorization'] = 'Bearer ${bearerToken!}';
  request.headers['content-type'] = 'application/json';
  request.bodyBytes = utf8.encode(
    jsonEncode({
      'algorithm': algorithm.name,
      'auth_data': authData,
    }),
  );
  final response = await httpClient.send(request);
  final responseBody = await response.stream.toBytes();
  if (response.statusCode != 200) unexpectedResponse(response, responseBody);
  final responseString = utf8.decode(responseBody);
  final json = jsonDecode(responseString);
  return json['version'] as String;
