Sorry, I have been busy lately.

I got the .data; issue but the problem is that the function refreshToken is still not being called.
After the latest update, I tested it again, it works fine.

Thank you @agordn52 for your support.

Hi @KhaledAlMana,

Hope you are well.
Thanks for your comments about the framework.

Re. the refreshToken method
Have you implemented the shouldRefreshToken?
This will tell Nylo when when to refresh the token.

E.g.

@override
Future<bool> shouldRefreshToken() async {
    User? user = Auth.user();

    if (user.token.expiryDate.isPast()) {
        // Check if the token is expired
        // This will trigger the [refreshToken] method
        return true;
    }
    return false;
}

The full docs are here, hope that helps :)

Hello @agordn52,

Yes, and during the debug, it is being invoked. However, refreshToken isn't invoked and all I have no clue why.

  @override
  Future<RequestHeaders> setAuthHeaders(RequestHeaders headers) async {
    AuthTokens? tokens = await StorageKey.userToken.read<AuthTokens>();
    if (tokens?.accessToken != null) {
      headers.addBearerToken(tokens?.accessToken ?? "");
    }
    return headers;
  }
  
  @override
  Future<bool> shouldRefreshTokens() async {
    try {
      AuthTokens? tokens = await StorageKey.userToken.read<AuthTokens>();
      if (tokens?.accessToken == null) {
        return false;
      }
      // If the token is expired, where expiredAt is epoch time
      // add 15 seconds to the expiry time to account for latency
      if (tokens?.expiresAt != null &&
          DateTime.now().isAfter(
              tokens?.expiresAt!.subtract(Duration(seconds: 15)) ??
                  DateTime.now())) {
        return true;
      } else {
        return false;
      }
    } catch (e) {
      print(e);
      return false;
    }
  }


  @override
  refreshToken(Dio dio) async {
    // debug is not hitting this function, nor printing the below.
    print("refreshing token");
    AuthTokens? tokens = await StorageKey.userToken.read<AuthTokens>();
    print(tokens?.refreshToken);
    if (tokens?.refreshToken == null) {
      await Auth.logout();
      routeToInitial(navigationType: NavigationType.pushAndForgetAll);
      return;
    }
    dynamic response = (await dio.post(baseUrl + "/auth/refresh",
            options: Options(
                headers: {"Authorization": "Bearer ${tokens?.refreshToken}"})))
        .data();
    //  Save the new token
    await StorageKey.userToken.store(response);
  }

Hi @KhaledAlMana,

Thanks for sharing your code.
I see a few things wrong that should be changed, please try the below 👍

@override
Future<RequestHeaders> setAuthHeaders(RequestHeaders headers) async {
    AuthTokens? tokens = await StorageKey.userToken.read<AuthTokens>();
    if (tokens?.accessToken != null) {
      headers.addBearerToken(tokens?.accessToken ?? "");
    }
    return headers;
}
  
@override
Future<bool> shouldRefreshTokens() async {
  AuthTokens? tokens = await StorageKey.userToken.read<AuthTokens>();
  if (tokens?.accessToken == null) {
    return true; // if accessToken is null then you should want to get a new 'AuthTokens'
   }
   // If the token is expired, where expiredAt is epoch time
  // add 15 seconds to the expiry time to account for latency
  if (DateTime.now().isAfter(tokens?.expiresAt?.subtract(Duration(seconds: 15)) ?? DateTime.now())) {
        return true;
  }
  return false;
}

@override
refreshToken(Dio dio) async {
    // debug is not hitting this function, nor printing the below.
    print("refreshing token");
    AuthTokens? tokens = await StorageKey.userToken.read<AuthTokens>();
    print(tokens?.refreshToken);
    if (tokens?.refreshToken == null) {
      await Auth.logout();
      routeToInitial(navigationType: NavigationType.pushAndForgetAll);
      return;
    }
    dynamic response = (await dio.post(baseUrl + "/auth/refresh",
            options: Options(
                headers: {"Authorization": "Bearer ${tokens?.refreshToken}"})))
        .data; // data() not a function, use data instead
    //  Save the new token
    await StorageKey.userToken.store(response);
}

I'm going to close this as resolved.

If you need help understanding networking, the docs on nylo.dev are up-to-date so you'll be able to learn more 👍
