在 Rails 中，是否可以限制谁可以使用 api 使用 google 登录? [英] In Rails, is it possible to limit who can log in with google using the api?

问题描述

是否可以只允许某些谷歌账户登录?例如 [e-mail] 是通过 google 托管的(它们实际上是 google 帐户).我只希望具有 @mycompany 的用户能够登录，这可能吗?你是用devise还是google api来做这个的?

Is it possible to only allow certain google accounts to log on? for example [e-mail] is host through google (they are actually google account). I want only user with the @mycompany to be able log on is this possible? do you do this with devise or google api?

谢谢:)

推荐答案

如果您使用的是 omniauth-google-oauth2，您可以通过在初始化期间为 hd 选项提供值来实现域限制.

If you are using omniauth-google-oauth2, you can accomplish domain restrictions using by providing a value for hd option during initialization.

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :google_oauth2, ENV['GOOGLE_CLIENT_ID'], ENV['GOOGLE_CLIENT_SECRET'], {
    scope: 'email, profile',
    hd: 'mycompany.com'
  }
end

也可以在处理回调的控制器中处理此问题.您可以根据 request.env["omniauth.auth"].

It's also possible to handle this in your controller which is handling the callback. You can deny users depending on values provided in request.env["omniauth.auth"].

class OmniauthCallbacksController < Devise::OmniauthCallbacksController
  def google_oauth2
    auth_details = request.env["omniauth.auth"]
    if auth_details.info['email'].split("@")[1] == "yourdomain.com"
      # do all the bits that come naturally in the callback controller
      user = User.from_omniauth(request.env["omniauth.auth"])
      if user.persisted?
        flash.notice = "Signed in Through Google!"
        sign_in_and_redirect user
      else
        session["devise.user_attributes"] = user.attributes
        flash.notice = "You are almost Done! Please provide a password to finish setting up your account"
        redirect_to new_user_registration_url
      end
    else
      # This is where you turn away the poor souls who do not match your domain
      render :text => "We're sorry, at this time we do not allow access to our app."
    end
  end
end
