错误的参数数量（2表示1） - TwitterController＃login中的ArgumentError

标签： ruby-on-rails ruby ruby-on-rails-3 twitter-oauth

我正在尝试将Twitter整合到我的网站上，以便用户可以使用Twitter进行注册和登录，但这是我去http://localhost:3000/twitter/login时出现的错误

ArgumentError in TwitterController#login

wrong number of arguments (2 for 1)

到目前为止，这是推特控制器

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

控制器内部是什么造成的？

使用此API的正确方法（根据其documentation）是通过传递哈希选项参数而不是“真实”方法参数：

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