我无法辨别为什么我的应用程序返回401 Unauthorized。我的机构控制器中的其他操作在没有登录的情况下正常工作。但是，这个和另一个页面返回401.如果登录，这些页面工作得非常好，但它们不应该要求登录。我甚至已经这样做了至于清空视图和操作，但页面仍然返回401.当通过fiddler调试时，我只是收到302重定向。
我尝试过在其他地方进行研究并尝试过Warden authentication recalls 401 Unauthorized的解决方案但没有成功。

检查您的INSTITController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。
您是否还可以使用预览方法发布您的INSTITController的摘录？
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
INSTITController真的有一个名为previewselectedvisits的方法吗？
