ios - Heroku上具有Devise的Rails 3.2应用程序:无法使用Mobile Safari登录

Question

我已经构建了一个简单的Rails应用并将其部署到heroku。该应用程序使用devise进行身份验证。在开发和生产环境中，一切正常，当尝试通过iOS上的Mobile Safari浏览器登录时，请接受。

Heroku日志显示以下内容:

2012-10-17T18:56:52+00:00 app[web.1]: Started POST "/users/sign_in" for 87.123.175.106 at 2012-10-17 20:56:52 +0200

2012-10-17T18:56:52+00:00 app[web.1]: WARNING: Can't verify CSRF token authenticity
2012-10-17T18:56:53+00:00 app[web.1]: Redirected to http://xxxxxxxx.herokuapp.com/

使用其他iOS浏览器(例如Opera)不会发生此问题。
我没有做任何自定义的工作(添加用户名除外)，它几乎是开箱即用的。

我读过几篇文章，其中模糊地解决了iOS和CSRF token 的问题，但是我对Rails还是很陌生，并不真正知道如何解决。有人可以帮忙吗？

更新:

根据this帖子中的建议，我注释了application_controller.rb中的protect_from_forgery以及application.html.erb中的csrf_meta_tags。
另外，我在config / session_store.rb中添加了:domain => :all。

没有任何帮助。令人讨厌的是，我不再收到Can't verify CSRF token authenticity错误了，但是以下日志:

有人有主意吗？

Answer 1

我在Heroku日志中看到相同的生产症状时遇到了同样的错误:

WARNING: Can't verify CSRF token authenticity

和尝试登录后的401未经授权的重定向。

对我来说，解决方法是将domain: :all添加到session_store中的config/initializers/session_store.rb中。
