我正在尝试通过Facebook验证并收到以下错误消息

在AuthenticationsController＃menu中的Koala :: Facebook :: AuthenticationError 类型：OAuthException，代码：190，消息：格式错误的接入令牌AQBiaE1v-pbSitzgNirHKSm7zNp3XoLAeHsvlFB626lARPBQCN98SBgIczjoRj3h8RQSVunm8gu-fHbO3H8-_9Ef9a5Lt00ixQ-wgum9p9FM5xN3WUvgc2BSyy1it2G4XlHNbQuwKYvsN-_7juH2NSXxMZmpaXh4qjjm13HWIjkYBWuyTIuJTJ7yUc97XixSMJtDbIIEBXfK52m_zIBTKvA4m8IoTOHDDoloeIhmARrGlMCmQG_vWZSMc ..（由作者删除最后字符）[HTTP 400]

这是我的rails控制器的代码，显示错误。基本上登录似乎工作。但是当我尝试通过@graph.get_object("me")访问我的个人资料时，不接受该令牌。

class AuthenticationsController < ApplicationController

  APP_ID="1234"
  APP_SECRET="1234"
  APP_CODE="XXXX"
  SITE_URL="http://local.myapp.com:3000/"

  def index
    if session['access_token']
      @face='Logged in -> <a href="authentications/logout">Logout</a>'
      @graph = Koala::Facebook::API.new(session["access_token"])
    else
      @face='<a href="authentications/login">Login</a>'
    end
  end

  def login
        session['oauth'] = Koala::Facebook::OAuth.new(APP_ID, APP_SECRET, SITE_URL + 'authentications/callback')
        redirect_to session['oauth'].url_for_oauth_code()
  end

  def logout
    session['oauth'] = nil
    session['access_token'] = nil
    redirect_to '/'
  end

    def callback
        session['access_token'] = params["code"]
        redirect_to '/authentications/menu'
    end

  def menu
     @ok="Hi!"
     if session['access_token']
       @face='Logged in -> <a href="/authentications/logout">Logout</a>'
       @graph = Koala::Facebook::GraphAPI.new(session["access_token"])

       ## LEADS TO ERROR
       @graph.get_object("me")

     else
       @face='<a href="/authentications/login">Login</a>'
     end

  end
end

使用sinatra的另一个例子中的代码正在运行。

#let Bundler handle all requires
require 'bundler'
require 'uri'

Bundler.require(:default)

# register your app at facebook to get those infos
APP_ID     = 1234
APP_SECRET = '1234'

class SimpleRubyFacebookExample < Sinatra::Application

  use Rack::Session::Cookie, secret: 'this_adfkaTGDGHDHJJJksk_0898932311_secret'

  get '/' do
    if session['access_token']
      'You are logged in! <a href="/logout">Logout</a>'

      @graph = Koala::Facebook::API.new(session["access_token"])
      user = @graph.get_object("me")
      feed = @graph.get_connections("me", "feed", {:limit => 999})
    else
      'Logout successful <br> Click to login <a href="/login">Login</a>'
    end
  end

  get '/login' do
    session['oauth'] = Koala::Facebook::OAuth.new(APP_ID, APP_SECRET, "#{request.base_url}/callback")
    redirect session['oauth'].url_for_oauth_code( scope: "read_mailbox,read_stream")
  end

  get '/logout' do
    session['oauth'] = nil
    session['access_token'] = nil
    redirect '/'
  end

  get '/callback' do
    session['access_token'] = session['oauth'].get_access_token(params[:code])
    redirect '/'
  end
end

我的控制器/我的令牌有什么问题？我把它输出到控制台，似乎没问题。任何有用的提示都表示赞赏！

正如我在评论中指出的那样，我遇到了返回令牌的问题，但是我无法在Rails中使用Koala获得正确的令牌。

我已经使用omniauth和omniauth-facebook gem解决了这个问题。

控制器：

class AuthenticationsController < ApplicationController

  def create
    auth = request.env["omniauth.auth"]
    session['fb_auth'] = auth
    session['fb_access_token'] = auth['credentials']['token']
    session['fb_error'] = nil
    redirect_to authentications_menu_path
  end

  def menu
    if session["fb_access_token"].present?
      graph = Koala::Facebook::GraphAPI.new(session["fb_access_token"]) # Note that i'm using session here
      @profile_image = graph.get_picture("me")
      @fbprofile = graph.get_object("me")
      @friends = graph.get_connections("me", "friends")
    end
  end

  def logout
    session['fb_access_token'] = nil
    session['fb_access_token'] = nil
    redirect_to root_path
  end

  protected

  def auth_hash
    request.env['omniauth.auth']
  end
end

初始化程序（Omniauth.rb）

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :facebook, '1234', '1233',
            :scope => 'read_stream'
end

路线：

Rails.application.routes.draw do

  match 'authentications/index', via: [:get, :post]
  match 'authentications/login', via: [:get, :post]
  match 'authentications/logout', via: [:get, :post]
  match 'authentications/menu', via: [:get, :post]
  get '/auth/:provider/callback', to: 'authentications#create'
  root :to => "authentications#index"

end

我知道我还没有将会话/用户/应用程序控制器分开（但是）但是我想与你分享我的解决方案。欢迎任何评论。
