Omniauth：引发ArgumentError：错误的参数数目（1 0）

我使用Omniauth与Facebook登录，但是当开始回调阶段我得到这个错误：Omniauth：引发ArgumentError：错误的参数数目（1 0）

我已经使用Cuba framework（这是非常类似于Sinatra）。这是我的配置：

app.rb

require "cuba" 
require "omniauth-facebook" 

Cuba.use Rack::Session::Cookie, 
    key: ENV['COOKIE_KEY'], 
    secret: ENV['COOKIE_SECRET'] 

Cuba.use OmniAuth::Builder do 
    provider :facebook, ENV['FBK_APP_ID'], ENV['FBK_APP_SECRET'] 
end 

Cuba.define do 
    on get '/auth/facebook/callback' do 
     res.write "Autentication with Facebook was successful!" 
    end 

    on get '/auth/failure' do 
    res.write "Something was wrong with Facebook authentication" 
    end 
end

缺少什么？

应该有一个上得块定义多条路线：

Cuba.define do 
    on get do 
    on '/auth/facebook/callback' do 
     res.write "Autentication with Facebook was successful!" 
    end 

    on '/auth/failure' do 
     res.write "Something was wrong with Facebook authentication" 
    end 
    end 
end

只是最后一点，它是'上“auth /中的Facebook /回调”'上“/ auth /中的facebook do'实例/回调'做'。有了这两个变化，现在它正在工作。 –
