錯誤的參數數量（2爲1） - TwitterController中的參數錯誤＃登錄

Question

我正在嘗試將Twitter集成到我的網站上，以便用戶可以使用Twitter註冊並登錄，但這裏是我在訪問http://localhost:3000/twitter/login時發生的錯誤

ArgumentError in TwitterController#login 

wrong number of arguments (2 for 1) 

這裏是Twitter的控制器至今

class TwitterController < ApplicationController 
    def index 
    end 

    def login 
    oauth.set_callback_url("http://#{request.host}/twitter/finalize") 

    session[:request_token] = oauth.request_token.token 
    session[:request_secret] = oauth.request_token.secret 

    redirect_url = oauth.request_token.authorize_url 
    redirect_url = "http://" + redirect_url unless redirect_url.match(/^http:\/\//) 
    redirect_to redirect_url 
    end 

    def finalize 
    end 

    def oauth 
    @oauth ||= Twitter::Client.new(APP_CONFIG[:twitter][:consumer_key], APP_CONFIG[:twitter][:consumer_secret]) 
    end 
end 

什麼是從控制器內部造成的呢？

使用這個API的正確方法（根據其documentation）是通過傳遞，而不是「真實」的方法參數哈希選項參數：

def oauth 
    @oauth ||= Twitter::Client.new(:consumer_key => APP_CONFIG[:twitter][:consumer_key], :consumer_secret => APP_CONFIG[:twitter][:consumer_secret]) 
    end
