Rails：无法通过Facebook验证您的身份，因为“无效凭证” [英] Rails: Could not authenticate you from Facebook because "Invalid credentials"

问题描述

我使用 https://github.com/plataformatec/整合omniauth-facebook设计/维基/ OmniAuth％3A-概述。但是我收到错误：

I integrated omniauth-facebook using https://github.com/plataformatec/devise/wiki/OmniAuth%3a-Overview. But I am getting error of :

Could not authenticate you from Facebook because "Invalid credentials".

在日志中，获取：

Authentication failure! invalid_credentials: OAuth2::Error, : {"error":{"message":"This authorization code has been used.","type":"OAuthException","code":100}}

我已经安装了设备。当我点击Facebook登录链接时，它回到设计标志www.mealnut.com/user/sign_in# = 并给出上述错误。我在 https://github.com/plataformatec上查看了无效凭证的解决方案/ devise / wiki / OmniAuth％3a-Overview ，正如我所说的那样，我的应用程序是App Type = Web的头文件。没有得到为什么它不工作。

I have devise installed. When i click on facebook sign in link, it comes back to devise sign "www.mealnut.com/user/sign_in#=" and gives above error. I checked the solution for "Invalid credentials" on https://github.com/plataformatec/devise/wiki/OmniAuth%3a-Overview and as mentioned there, my app is header set for App Type = Web. Not getting why it is not working.

另外我的应用程序正在等待从Facebook的审查。但我不认为这与这个错误有关。以下是我为omniauth-facebook做的事情：

Also my app is pending review from facebook. But i don't think it is related to this error. Following are the things i did for omniauth-facebook:

Gemfile包含：

Gemfile contains:

gem "omniauth", "~> 1.1.4"
gem 'omniauth-facebook', '1.4.1'

在用户模型中，添加：

devise :omniauthable, :omniauth_providers => [:facebook]
attr_accessible :provider, :uid

  def self.find_for_facebook_oauth(auth, signed_in_resource=nil)
    user = User.where(:provider => auth.provider, :uid => auth.uid).first
    unless user
    user = User.create(name:auth.extra.raw_info.name,
                       provider:auth.provider,
                       uid:auth.uid,
                       email:auth.info.email,
                       password:Devise.friendly_token[0,20]
                      )
  end
user
end

devise.rb

devise.rb

require "omniauth-facebook"
config.omniauth :facebook, "APP_ID", "APP_SECRET", :scope => "offline_access, email" 

omniauth.rb：

omniauth.rb:

OmniAuth.config.logger = Rails.logger
Rails.application.config.middleware.use OmniAuth::Builder do
 provider :facebook, ENV['FACEBOOK_KEY'], ENV['FACEBOOK_SECRET'], {:provider_ignores_state => true}
end

route.rb：

devise_for：user，：controllers => {：omniauth_callbacks =>omniauth_callbacks}

devise_for :user, :controllers => { :omniauth_callbacks => "omniauth_callbacks" }

Omniauth控制器：

Omniauth controller:

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController
  def facebook
    @user = User.find_for_facebook_oauth(request.env["omniauth.auth"], current_user)

    if @user.persisted?
      sign_in_and_redirect @user, :event => :authentication #this will throw if @user is not activated
      set_flash_message(:notice, :success, :kind => "Facebook") if is_navigational_format?
    else
      session["devise.facebook_data"] = request.env["omniauth.auth"]
      redirect_to new_user_registration_url
    end
  end
end

有人可以帮助吗？

推荐答案

想到我会在这里筹码，因为当我尝试搜索一个解决方案时，为了找到解决方案，因为无效的凭据，无法验证你的Facebook

Thought I'd chip in here since this came up for me when trying to search for a solution for Could not authenticate you from Facebook because "Invalid credentials"

问题是与Facebook API版本> = 2.3，您需要设置 {token_params：{parse：：json}} 给你的提供者配置。

The problem is with Facebook API version >=2.3 you need to set {token_params: {parse: :json}} to your provider config.

devise.rb

devise.rb

config.omniauth :facebook,
    APP_ID,
    APP_SECRET,
    token_params: { parse: :json } # <----- this line is NB

答案发现于此问题 omniauth-oauth2
