我认为我的会话等都搞砸了，因为我最近添加了代码以确保正确的协议（某些页面上的 https，而其他页面上的 http）。不过我不确定。Filter chain halted as :ensure_proper_protocol rendered or redirected但我一直在我的日志中看到。

`:ensure_proper_protocol 方法是指我在应用程序控制器中拥有的方法：

    class ApplicationController < ActionController::Base

      CONTROLLERS_THAT_REQUIRE_SSL = ['check_out', 'users', 'sessions', 'registrations', 'addresses', 'catalog_requests', 'wine_club/orders']

      def ensure_proper_protocol
        unless Rails.env.development? || Rails.env.test?
          if request.format == "text/html" && request.protocol["https"] && !CONTROLLERS_THAT_REQUIRE_SSL.include?(params[:controller])
            redirect_to "http://" + request.host + request.path
          end
        end
      end

对于 CONTROLLES_THAT_REQUIRE_SSL 中的控制器，我添加force_ssl如下：

class CheckOutController < ApplicationController

   force_ssl
   ...

但是，我想知道协议中的切换是否会搞砸我的会话。我的会话问题和这个错误有关吗？如何修复“过滤器链停止”错误？

我遇到的会话问题与设计和身份验证有关。我有一个前置过滤器：authenticate_user！虽然我设法登录，但它似乎并没有保持登录状态。问题是没有错误消息。它只是出于某种原因注销，我很确定这是因为重定向，因为我的应用程序控制器中有一个 before 过滤器来查看用户是否已登录，并且它使用 devise helper 方法user_signed_in?来查看是否用户已登录。看看我的日志：

登录后它会将我重定向到主页，这没关系，但之后它会从 http:// ... / 重定向到 https:// ... / ，这导致用户不再登录。这可能是因为我的会话没有像我配置的那样存储在数据库中吗？我的 config/initializers/session_store.rb 中确实有这一行：

mysite::Application.config.session_store :active_record_store
