Rails authenticate_or_request_with_http_basic 响应

Question

如果身份验证失败，我会尝试重定向到 root_path。 目前，它只是使用 HTTP Basic: Access denied 更改页面的正文。

这是我的控制器：

class ProjectsController < ApplicationController
 before_filter :http_basic_auth, only: [:show]

  def http_basic_auth
    if (authenticate_or_request_with_http_basic do |user, password| password == @project.passcode && user == @project.passcode end if @project.private?)
    true
    else
      response.headers["Location"] = url_for(root_path)
    end
  end

end

研究了以下内容，但我仍然无法正确：
Rails: What is the location option for in the render method

http://api.rubyonrails.org/classes/ActionController/HttpAuthentication/Basic/ControllerMethods.html#method-i-authenticate_with_http_basic

我还没有让这个工作：

尝试使用authenticate_with_http_basic 代替authenticate_or_request_with_http_basic

来自Rails API documentation 的示例的 sn-p：

    if user = authenticate_with_http_basic { |u, p| @account.users.authenticate(u, p) }
      @current_user = user
    else
      request_http_basic_authentication
    end
