如何在抓取网站时阻止Google导致此错误?我不想关闭“protect_from_forgery”,除非这样做是安全的。
[fyi] method=GET path=/users format=*/* controller=users action=show status=200 duration=690.32 view=428.25 db=253.06 time= host= user= user_agent=Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html) session= params={""} ()
[hmm] Security warning: an embedded <script> tag on another site requested protected JavaScript. If you know what you're doing, go ahead and disable forgery protection on this action to permit cross-origin JavaScript embedding. (pid:)

[omg] ActionController::InvalidCrossOriginRequest (Security warning: an embedded <script> tag on another site requested protected JavaScript. If you know what you're doing, go ahead and disable forgery protection on this action to permit cross-origin JavaScript embedding.):
actionpack (4.1.4) lib/action_controller/metal/request_forgery_protection.rb:217:in `verify_same_origin_request'
控制器以此响应
respond_to do |format|
format.js { render template: 'users/flag', layout: "some_layout" }
end
我无法重新创建错误,当我通过浏览器执行此操作时似乎工作正常
到目前为止,我已经查看了以下资源,但大多数似乎只是建议盲目转向CSRF或没有答案。
澄清:应该保护该操作免受CSRF的影响,但我想阻止Google抓取它或者通过抓取页面生成错误。即。)我希望虚假的安全警告消失而不会实际损害我的安全功能。
Googlebot使用格式“* / *”(http://apidock.com/rails/Mime),应用程序呈现js,因为它是唯一可用的东西。由于它是远程的,它正确地导致无效的COR。
这可以使用以下方法重现:
curl -H "Accept: */*" https://www.example.com/users/123/flag
解决方法是为蜘蛛抓取一个html后备资源:
respond_to do |format|
format.html { render template: 'users/flag' }
format.js { render template: 'users/flag', layout: "some_layout" }
end
根据rails指南中的“远程标签的CSRF保护”:
在测试的情况下,您也在做客户端,请从以下位置更改:
get:index,format :: js
至:
xhr:get,:index,格式:: js
如果你想让这条路线跳过csrf检查,白色列出路线使用类似的东西:
protect_from_forgery :except => :create
