Rails:无法通过Facebook验证您,因为"凭据无效"

Question

我使用https://github.com/plataformatec/devise/wiki/OmniAuth%3a-Overview整合了omniauth-facebook .但我得到的错误是:

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

在日志中,得到这个:

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

我已经安装好了.当我点击Facebook登录链接时,它回来设计标志"www.mealnut.com/user/sign_in# = "并给出上述错误.我在https://github.com/plataformatec/devise/wiki/OmniAuth%3a-Overview上检查了"无效凭证"的解决方案,如上所述,我的应用程序是App Type = Web的标题集.不明白为什么它不起作用.

我的应用程序正在等待来自Facebook的评论.但我不认为这与此错误有关.以下是我为omniauth-facebook所做的事情:

Gemfile包含:

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

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

omn​​iauth.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"}

Omniauth控制器:

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

有人可以帮忙吗？

Answer 1

以为我会在这里筹码,因为当我试图搜索无法通过Facebook验证您的解决方案时,我想到了这个因为"无效的凭据"

问题是Facebook API版本> = 2.3您需要设置{token_params: {parse: :json}}为您的提供程序配置.

devise.rb

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

回答找到这个问题的omniauth-oauth2

更新2018年8月:再次出现"无效凭证"问题,我不得不删除token_params它再次工作的设置 - 所以这可能不再是一个问题了

Answer 2

搞定了!

我的routes.rb和user.rb错了.并改变了omniauth.rb!这是前一个和后一个文件:

我的routes.rb是:

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

所以它是两次调用设计.我改成了:

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

改变了我的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

对此:

OmniAuth.config.logger = Rails.logger

另外,我在user.rb模型(重大错误)之外定义了方法"def self.find_for_facebook_oauth(auth,signed_in_resource = nil)".

所以现在让它完美运作:-)

希望这有助于某人.
