Ошибка с OAuth2 gem v 0.5.0

Question

Я получаю очень непрозрачную ошибку со следующим кодом:

client = OAuth2::Client.new(
    "#{FACEBOOK_CONFIG['application_id']}", "#{FACEBOOK_CONFIG['secret_key']}",
    :site => 'https://graph.facebook.com'
    )
token = OAuth2::AccessToken.new(client, fb_token)
token.get('/me')

когда я выполняю token.get ('/ me'), я получаю следующий вывод:

OAuth2 :: Исключение ошибки: OAuth2 :: Ошибка

Этот код отлично работает с v0.4.1, но не работает с v0.5.0

Вот трассировка стека:

Answer 1

У меня такая же проблема.

Глядя на код драгоценного камня, это потому что ответ Facebook - это HTTP-код 400..599. когда 400..599 e = Error.new (ответ) поднять e, если выберет [: rise_errors] || опции [: raise_errors]

К сожалению, связь между моим сервером и Facebook использует HTTPS, поэтому я пока не смог перехватить проблемный запрос.

UPDATE

Я получил 400 ошибок от Facebook:

OAuth "Платформа Facebook" "invalid_request" "Активный токен доступа должен использоваться для запроса информации о текущем пользователе."

ОБНОВЛЕНИЕ 2

Интересное обсуждение здесь: Facebook access_token недействителен?

В итоге я вернул oauth2 обратно к 0.4.1, и мой FB-вход и запросы работают.

Answer 2

Я только недавно использовал Omniauth, но похоже, что ваш след говорит, что у вас есть что-то подобное в вашем oauth_helper:

 def try_access_token
   begin
     ..
   rescue OAuth2::AccessDenied

   end
 end

Если это так, попробуйте изменить OAuth2::AccessDenied на OAuth2::Error. Oauth2::Error предоставляет атрибут .code, который можно проверить, чтобы определить, является ли это отказом в доступе.
