Question

我正在使用Vagrant在Windows 7 32位主机中使用ubuntu/trusty32框设置Rails应用。该应用已通过Google OAuth登录。 Gemfile有以下宝石：

gem 'omniauth'
gem 'omniauth-google-oauth2'

在/config/initializers/devise.rb：

  config.omniauth :google_oauth2, ENV["GOOGLE_APP_ID"], ENV["GOOGLE_APP_SECRET"]
  OmniAuth.config.full_host = lambda do |env|
    forwarded = env['HTTP_X_FORWARDED_FOR']
    forwarded.blank? ? "#{env['rack.url_scheme']}://#{env['HTTP_HOST']}" : "https://#{env['HTTP_HOST']}"
  end

当我尝试登录时，它会在此URL处停止，显示“您正在被重定向”，接下来没有任何事情发生。

http://localhost:3000/omniauths/auth/google_oauth2/callback?state=xxxx&code=xxx

我收到了以下日志：

代码不是我的，我也不是红宝石专家。所以我不知道为什么我会被困在那个屏幕上。我还找到了一个控制器：

class SessionController < Devise::OmniauthCallbacksController
  def google_oauth2
    @omniauth = Omniauth.find_for_google(request.env['omniauth.auth'])

    if @omniauth&.persisted?
        @omniauth.user.last_sign_in = Time.now
        @omniauth.user.save
        flash[:notice] = 'I signed in with Google authentication'
        sign_in_and_redirect @omniauth, event: :authentication
    else
        #redirect_to new_user_registration_url, alert: @user.errors.full_messages.join("\n")
        redirect_to '/', status: :forbidden
    end
  end
end

以下是config/routes.rb

Rails.application.routes.draw do
    devise_for :omniauths, controllers: {
      omniauth_callbacks: "session"
    }
    mount RailsAdmin::Engine => '/rails_admin', as: 'rails_admin'

    post '/api', to: "api#post"
    post '/error_catch', to: "api#error_catch"
    post '/error_log', to: "api#error_log"
    get '/file/:uuid/:filename', to: "api#file"
    get '/svg_parts/*dxf_path', to: "svg#part"
    post '/svg/project(.:format)'
    post '/svg/requirement(.:format)'
    get '/svg/test(.:format)'
    get '/pdf/owner_estimate'
    get '/pdf/builder_estimate'
    get '/pdf/wholesale_estimate'

    get '/api/perform_test'

    get '/pdf/requirement'

    root to: "angular#index"
    get '/assets/*path', controller: 'application', action: 'handle_404'
    get '*path', to: "angular#index"
end

此问题的信息不够用？我还可以提供更多可能有用的信息。

gemfile.rb

gem 'omniauth-google-oauth2'

config/initializer/omniauth.rb

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :google_oauth2, ENV["GOOGLE_CLIENT_ID"], ENV["GOOGLE_CLIENT_SECRET"],
    {
      :name => "google",
      :scope => "email, profile, plus.me, http://gdata.youtube.com",
      :prompt => "select_account",
      :image_aspect_ratio => "square",
      :image_size => 50
    }
end

config/initializer/devise.rb

config.omniauth :google_oauth2, ENV["GOOGLE_CLIENT_ID"], ENV["GOOGLE_CLIENT_SECRET"], {}

routes.rb

devise_for :users, controllers: {registrations: 'users/registrations',omniauth_callbacks: 'users/omniauth_callbacks'}

controllers/users/omniauth_callbacks_controller.rb

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController  

 def google_oauth2
    @user = User.from_omniauth(request.env["omniauth.auth"])

    if @user.persisted?
      flash[:notice] = I18n.t "devise.omniauth_callbacks.success", :kind => "Google"
      sign_in_and_redirect @user, :event => :authentication
    else
      session["devise.google_data"] = request.env["omniauth.auth"]
      redirect_to new_user_registration_url
    end
  end
end

app/views/devise/registrations/new.html.erb

<%- resource_class.omniauth_providers.each do |provider| %>

    <%= link_to  omniauth_authorize_path(resource_name, provider) do %>
      <i class="fa fa-google-plus-official fa-2x" aria-hidden="true"</i>

  <% end %>
<% end -%>
[... orginal devise view]

/app/models/user.rb

class User
  devise :omniauthable, omniauth_providers: [:google_oauth2]
  [...]
end

我希望这会对你有所帮助！

无法使用omniauth-google-oauth2登录，导致您被重定向
