Heroku中的Rails 3.2应用程序与Devise：无法使用移动Safari登录

Question

我已经构建了一个简单的Rails应用程序并将其部署到heroku。该应用程序使用设计进行身份验证。在开发和生产环境中一切正常，在iOS上通过Mobile Safari浏览器尝试登录时接受。

Heroku的日志说以下内容：

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

2012-10-17T18:56:53+00:00 app[web.1]: Redirected to http://xxxxxxxx.herokuapp.com/ 

问题不与其他iOS浏览器如Opera发生。 我没有做任何自定义的东西来设计（除了添加用户名），它几乎是开箱即用的。

我已经阅读了几篇文章，其中iOS和CSRF令牌的问题隐约得到解决，但我对rails很新，并且不知道如何解决这个问题。任何人都可以帮忙吗？

UPDATE：

正如this建议后，我在application_controller.rb注释掉protect_from_forgery以及在application.html.erb的csrf_meta_tags。 另外，我将:domain => :all添加到config/session_store.rb。

没有帮助。 Obiously，我没有得到Can't verify CSRF token authenticity错误了，但以下日志：

有人的想法？

Answer 1

我有同样的errorm看到在Heroku的日志，生产相同的症状：

• WARNING: Can't verify CSRF token authenticity
• 并登录尝试后，401重定向未经授权。

对我来说，决议是在config/initializers/session_store.rb添加domain: :all到session_store。
