Question

我正在使用ruby＆＃34; 2.3.1＆＃34;和＆＃34; rails＆＃34;，＆＃34; 5.0.0.rc1＆＃34;另外，使用Devise ....

我想检测Cookies＆amp;在此基础上，提供一条简单的消息说“用户必须启用cookie”＃39;

这是我的代码：

路线：

match "cookie_test" => "application#cookie_test", as: "cookies_test", via: :all

application_controller

require "activerecord/session_store"
require "cookie_detection"
class ApplicationController < ActionController::Base

  include CookieDetection
  include PublicActivity::StoreController
  include SuperadminHelper
  include GoogleHelper ....

LIB / cookie_detection.rb

module CookieDetection

  def self.included(base)
    base.before_filter :cookies_required, :except => ["cookie_test"]
  end

  # checks for presence of "cookie_test" cookie
  # (should have been set by cookies_required before_filter)
  # if cookie is present, continue normal operation
  # otherwise show cookie warning at "shared/cookies_required"

  def cookie_test
    Util.log " COOKIE TEST METHOD"
    if cookies["cookie_test"].blank?
      Util.log " COOKIE TEST IS BLANK"
      logger.warn("=== cookies are disabled")
      render "shared/cookies_required", layout: "header-only"
    else
      Util.log "I AM IN ELSE OF COOKIE TEST"
      redirect_back_or_default(dashboard_path)
    end
  end

  protected

  # checks for presence of "cookie_test" cookie.
  # If not present, redirects to cookies_test action
  def cookies_required
    Util.log " COOKIE REQUIRED METHOD"
    return true unless cookies["cookie_test"].blank?
    cookies["cookie_test"] = Time.now
    session[:return_to] = request.url
    redirect_to(cookies_test_path)
  end

end

cookies_required.html.erb

<h2>Cookies must be enabled to use AgentBright.</h2>

似乎陷入了一个循环中。超时：

如何获取共享/ cookies_required.html.erb进行渲染？有任何想法吗？非常感谢。

Answer 1

Completed 401 Unauthorized

查看其身份验证问题。你在使用Devise吗？如果是这样，请在application_controller.rb中更改此内容：

before_action :authenticate_user!

到此：

before_action :authenticate_user!, except: :cookie_test
