为什么我收到“这个授权码已被使用”前2位用户之后？ [英] Why am I receiving "This authorization code has been used" after the first 2 users?

问题描述

我正在使用Omniauth-Facebook来创建和验证用户。它适用于两个第一个用户，但第三个用户失败。我还可以认证这是CREATE进程失败。这似乎是一个常见的问题，没有解决方案。

I'm using Omniauth-Facebook to create and authenticate User. It works for the two first users, but fails for the third one. I still can authenticate; it's the CREATE process which fails. This appears to be a common issue without a solution.

error.log：

error.log:

 facebook) Callback phase initiated.
(facebook) Authentication failure! invalid_credentials: OAuth2::Error, : 
{"error":{"message":"This authorization code has been used.","type":"OAuthException","code":100}}

onmiauth.rb：

onmiauth.rb:

 Rails.application.config.middleware.use OmniAuth::Builder do
  provider :developer unless Rails.env.production?
  provider :facebook, 'xxxxxxx', 'xxxxxxxxxxxxxxxxxxxxxxxxxxxx',
           :scope => 'email,user_birthday,user_hometown,user_location', :display => 'popup'
end

SessionsController：

SessionsController:

class SessionsController < ApplicationController
  def create
      auth = request.env["omniauth.auth"]
      player = Player.find_by_provider_and_uid(auth["provider"], auth["uid"]) || Player.create_with_omniauth(auth)
      session[:player_id] = player.id
      redirect_to bienvenue_index_path, :notice => "Signed in!"
  end

  def destroy
  session[:player_id] = nil
  redirect_to root_url, :notice => "Signed out!"
  end
end

我的播放器型号：

class Player < ActiveRecord::Base



  attr_accessible :email, :gender, :habitation, :image, :nom, :nom_complet, :prenom, :provider, :token, :uid, :taille, :poids, :pied, :poste_prefere, :vehicule
  has_many :matches
  has_many :activities

  validates_presence_of :prenom
  validates_presence_of :nom

  def self.create_with_omniauth(auth)

    large = "http://graph.facebook.com/#{auth["uid"]}/picture?type=large"

      create! do |player|
        player.provider = auth["provider"]
        player.uid = auth["uid"]
        player.nom_complet = auth["info"]["name"]
        player.nom = auth["info"]["last_name"]
        player.prenom = auth["info"]["first_name"]
        player.image = auth["info"]["image"]
        player.image_large = large
        player.email = auth["info"]["email"]
        player.gender = auth["extra"]["raw_info"]["gender"]
        player.habitation = auth["extra"]["raw_info"]["location"]["name"]          
        player.token = auth["credentials"]["token"]

      end
    end 

end

推荐答案

对于绊倒同样错误的其他人来说，我的另一个问题是由另一个问题引起。

For other people who stumble over this same error mine was caused by another issue.

通过 skip_before_filter： Users :: OmniauthCallbacksController

为什么我认为这是有效的：

最初我跟踪了这​​个 bug 在omniauth_facebook gem中。

Initially I followed the the trail to this bug in the omniauth_facebook gem.

这突出显示了错误消息与两个FB回调请求快速连续发送的事实有关。不幸的是，我没有定义两次的全面细节，所以最初没有办法解决这个问题。

This highlighted the fact that the error message relates to the fact that two FB callback requests are being sent in quick succession. Unfortunately, I didn't have the omniauth details defined twice so initially couldn't work out where that was coming from.

然后我意识到在我的 ApplicationController 我有 before_filter：authenticate 。我认为发生了什么事情是Facebook的回拨请求正在触发此认证屏障，然后立即请求新的身份验证。

Then I realised that in my ApplicationController I have before_filter :authenticate. I think what was happening was that the Facebook callback request was hitting this authentication barrier and then immediately request a new authentication.

告诉Devise跳过此动作解决了我的问题。

Telling Devise to skip this action resolved the issue for me.
