requestOAuthToken method

Future<String> requestOAuthToken({ required String fromParticipantId, required Uri redirectUri, required String delegateTo, ConnectorRef? connector, OAuthClientConfig? oauth, int timeout = 60 * 5, })

Client -> server: Ask another participant (or the server) to obtain an OAuth token for us. Returns the access_token string.

This matches the Python signature: request_oauth_token(authorization_endpoint, token_endpoint, scopes, timeout, from_participant_id)

Implementation

Future<String> requestOAuthToken({
  required String fromParticipantId,
  required Uri redirectUri,
  required String delegateTo,
  ConnectorRef? connector,
  OAuthClientConfig? oauth,
  int timeout = 60 * 5,
}) async {
  final req = {
    if (connector != null) "connector": connector.toJson(),
    if (oauth != null) "oauth": oauth.toJson(),
    "redirect_uri": redirectUri.toString(),
    "timeout": timeout,
    "participant_id": fromParticipantId,
    "delegate_to": delegateTo,
  };

  final res = await room.sendRequest("secrets.request_oauth_token", req) as JsonResponse;
  final accessToken = (res.json["access_token"] as String?) ?? "";
  if (accessToken.isEmpty) {
    throw RoomServerException("Invalid response: missing access_token");
  }
  return accessToken;
}
