ruby-on-rails – Rails redirect_to是从https(正确)重定向到http(不正确)？

class ApplicationController < ActionController::Base
  protect_from_forgery with: :exception
  before_action :require_login

  def require_login
    unless logged_in?
      flash[:alert] = "You must be logged in to access this section."
      redirect_to login_path
    end
  end

  def logged_in?
    # more logic
  end
end

当我在没有登录的情况下访问example.com时,我会按预期重定向到example.com/login.但是,我在控制台中看到此错误：

The page at 'https://example.com/login' was loaded over HTTPS, but displayed
insecure content from 'http://example.com/login': this content should also
be loaded over HTTPS.

网络选项卡似乎表明我的redirect_to指向HTTP而不是HTTPS.当它到达HTTP时,它会自动重定向到HTTPS.

Request URL:http://example.com/login
Request Method:GET
Status Code:301 Moved Permanently

# In the response headers:
Location:https://example.com/login

有没有办法告诉redirect_to它应该使用HHTPS而不是HTTP,或者这是一个nginx配置？我认为使用login_path而不是login_url会解决问题,因为它应该是相对于基础的,但这似乎不起作用.

更新：

我还想过使用force_ssl,但担心我正在用锤子敲针.如果我弄错了,请随意纠正我.

class ApplicationController < ActionController::Base
  force_ssl # use HTTPS for all actions

  protect_from_forgery with: :exception
  before_action :require_login

  def require_login
    unless logged_in?
      flash[:alert] = "You must be logged in to access this section."
      redirect_to login_path
    end
  end

  def logged_in?
    # more logic
  end
end
