how to implement refresh token?

[vincenzopalazzo]

Hi, sorry for the delay here.

Can you make a small example of the use case? for now, my suggestion is to create a new client to refresh the token stored inside it or just update the link inside the client.

I don't think that is something the client should handle. Instead, you should implement a link with your desired refresh logic.

Do we have an example of that ? I try using http_interceptor but never pass the the interceptRequest:

GraphQLClient(
        cache: GraphQLCache(),
        link: HttpLink(
          MY_UrL,
          httpClient: InterceptedClient.build(
            interceptors: [
              LoggingInterceptor(
                  authLocalDataSource: authLocalDataSource,
              ),
            ],
            client: http.Client(),
          ),
        ),
      )

The interceptor:

class LoggingInterceptor implements InterceptorContract {
  LoggingInterceptor({
    required this.authLocalDataSource,
  });

  final AuthLocalDataSource authLocalDataSource;

  @override
  Future<RequestData> interceptRequest({required RequestData data}) async {
    try {
      final result = await authLocalDataSource.getCredentials();
      data.headers['Authorization'] = 'Bearer ${result.accessToken}';
    } catch (e) {
      return data;
    }
    return data;
  }

  @override
  Future<ResponseData> interceptResponse({required ResponseData data}) async {
    return data;
  }
}

I'm looking for a simple example of that. Maybe I make it wrong.

Finaly I find a way to do it with gql_dio_link :

GraphQLClient(
        cache: GraphQLCache(),
        link: DioLink(
          'graphql',
          client: dio,
        ),
      )

And the dio :

Dio(
        BaseOptions(
          baseUrl: URL_SERVER,
        ),
      )..interceptors.add(OauthInterceptor(
          authLocalDataSource: authLocalDataSource,
        ));

@ShourovRoy The code is meaningless here, why do you will not a good format PR to improve the docs? we love this type of PR

[Kiruel]

I will make a PR for the doc when I got some time ;) !
