ruby-on-rails-3 - Rails devise 401 未经授权特定页面

Question

我无法辨别为什么我的应用返回 401 Unauthorized。我的机构 Controller 中的其他操作在未登录时工作正常。但是，此页面和另一个页面返回 401。如果登录，这些页面工作得很好，但它们不应该要求登录。我什至已经这样了至清空 View 和操作，但页面仍然返回 401。通过 fiddler 调试时，我只是收到 302 重定向。

我尝试在其他地方进行研究，并尝试了 Warden authentication recalls 401 Unauthorized 中的解决方案没有成功。

Answer 1

检查你的InstitutionsController和ApplicationController的代码——查找其中包含current_user或before_filter的语句

 class InstitutionsController < ApplicationController
    before_filter :login_required, :only => [:method1,:method2]
    ...
 end

可能是您尝试调用的方法被列为需要身份验证，但您尚未登录。

您还可以发布带有预览方法的InstitutionsController 的摘录吗？

另一个可能的问题是您的路线可能定义不正确:

  match 'visit/schedule/preview' => 'institutions#previewselectedvisits', :as => :preview_visits, :via => :get

InstitutionsController 真的有一个名为 previewselectedvisits 的方法吗？
