Question

我按照以下说明实施了devise和omniauth-facebook：

https://github.com/plataformatec/devise/wiki/OmniAuth:-Overview

问题

我的“facebook”回调函数会被调用。

如果我取消注释“facebook”功能，则会发生错误。路由似乎工作正常

但是，函数内的代码似乎没有被执行。

以下代码不会引发任何错误。

我几天来一直在研究这个问题。请帮忙......

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController


  def facebook
    raise params.inspect
  end

  def failure
    redirect_to root_path
  end

end

Answer 1

我以稍微不同的方式使用了回调：你应该在omniauth.rb文件中声明回调：

Rails.application.config.middleware.use OmniAuth::Builder do
    provider :facebook, "app_id", "password",
        scope: 'public_profile', info_fields: 'id,name,link', display: 'popup', callback_path: '/stores/facebook_callback'

end

当然要添加＆＃39; facebook_callback＆＃39;控制器中的操作（我的情况是存储），并将其添加到路径文件中。

Answer 2

可能是其他身份验证机制干扰了omniauth流并阻止了回调的执行。

您可以检查 ApplicationController 中是否有可能引起问题的before_action语句，并将它们作为skip_before_action添加到 OmniauthCallbacksController 中。

例如如果您有：

class ApplicationController < ActionController::Base
  before_action :authenticate_user
  ...

然后添加：

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController
  skip_before_action :authenticate_user
  ...

当我遇到完全相同的问题时，它为我解决了该问题。
