getLocalAliases method

Future<List<String>> getLocalAliases(String roomId)

Get a list of aliases maintained by the local server for the given room.

This endpoint can be called by users who are in the room (external users receive an M_FORBIDDEN error response). If the room's m.room.history_visibility maps to world_readable, any user can call this endpoint.

Servers may choose to implement additional access control checks here, such as allowing server administrators to view aliases regardless of membership.

Note: Clients are recommended not to display this list of aliases prominently as they are not curated, unlike those listed in the m.room.canonical_alias state event.

roomId The room ID to find local aliases of.

returns aliases: The server's local aliases on the room. Can be empty.

Implementation

Future<List<String>> getLocalAliases(String roomId) async {
  final requestUri = Uri(
      path: '_matrix/client/v3/rooms/${Uri.encodeComponent(roomId)}/aliases');
  final request = Request('GET', baseUri!.resolveUri(requestUri));
  request.headers['authorization'] = 'Bearer ${bearerToken!}';
  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['aliases'] as List).map((v) => v as String).toList();
