Файл simple_client.rb ниже прекрасно работает с моим сервером эмуляции cas;однако файл casport.rb (основной файл стратегии oa-casport OmniAuth) неправильно устанавливает или передает заголовки / формат.Он должен быть динамически назначен классу, чтобы опции инициализатора могли его создавать, но я не уверен, как это сделать, кроме того, как я пытался это сделать здесь.Я был совершенно уверен, что у меня это работало в какой-то момент, но я не вижу другого объяснения, почему это не будет работать, учитывая простоту файла клиента.
Любая помощь очень важна при вычисленииузнать, как лучше установить динамические настройки format и headers для HTTParty в моем классе Casport.Как и раньше, он просто возвращает представление HTML для этого конкретного пользователя.
simple_client.rb:
### simple_client.rb - works properly w/ parsed XML response
### The cas.dev project is coming from this Github repo:
