• Add urlLancher: (url) => print(url) to the Authenticator

• Paste the given URL in a browser that already has devtools open on the networking page

• Copy the URL of the 2nd request ( sko-app://sign-in-callback?code=... )

• Open a new browser tab and paste the url, replacing sko-app:// with localhost:3000/

• It should work.

• We can't provide localhost:3000 as redirectUri because then we get an error from the CAS

A cache provider storing the responses in JSON files #

This is not a great idea, the example isn't complete and it was written in a rush but this should give a rough idea of how things should be structured.

class FSCacheProvider extends CacheProvider {
  Map<String, String> _index = {};

  @override
  Future<String> get(String key) async {
    return await File(filename(key)).readAsString();
  }

  @override
  bool raw() => false;

  @override
  void set(String key, String value) {
    _index[filename(key)] = DateTime.now().toIso8601String();
    File('./cache/index.json').createSync(recursive: true);
    File('./cache/index.json').writeAsString(jsonEncode(_index));
    File(filename(key))
      ..createSync(recursive: true)
      ..writeAsString(value);
  }

  @override
  Future<bool> shouldUseCache(String key) async {
    //TODO compare dates
    return _index.keys.contains(filename(key));
  }

  String filename(String url) {
    return './cache${Uri.parse(url).path}/${Uri.parse(url).query}.json';
  }

  init() {
    _index = File('./cache/index.json').existsSync()
        ? jsonDecode(File('./cache/index.json').readAsStringSync())
            .map<String, String>(
                (key, value) => MapEntry(key as String, value as String))
        : {};
    File('.cache/index.json').createSync(recursive: true);
  }
}
