Twitter OAuth :: Несанкционированный 400 Bad Request, делая RailsApps Oauth tutorial

Question

Я работаю над учебником RailsApps Oauth и не могу понять, как не получить OAuth :: Unauthorized 400 Bad Request при посещении/auth/twitter.

Все было точно так же, как https://github.com/RailsApps/rails-omniauth.

Проводили часы поиска в Интернете, несколько вариантов обратного вызова, размещение различных переменных среды.

self.token_request(http_method, uri.path, token, request_options, arguments) 
    when (400..499) 
    raise OAuth::Unauthorized, response 
    else 
    response.error! 
    end 

Помощь очень ценится, просто продолжайте учиться.

Answer 1

ваших ключей аутентификации, наиболее вероятно, могут быть сконфигурированы так, просто удалите ENV и скобки, как показано ниже, попробуйте изменить ...

от:

Rails.application.config.middleware.use OmniAuth::Builder do 
    provider :twitter, ENV['TWITTER_KEY'], ENV['TWITTER_SECRET'], 
end 

к:

Rails.application.config.middleware.use OmniAuth::Builder do 
    provider :twitter, 'TWITTER_KEY', 'TWITTER_SECRET' 
end
