Ios Heroku上的Rails 3.2应用程序，带有designe:Can'；t使用Mobile Safari登录

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Desive进行身份验证。在开发和生产环境中一切正常，当您尝试通过iOS上的Mobile Safari浏览器登录时，请接受

Heroku日志说：

其他iOS浏览器（如Opera）不会出现此问题。 我没有做任何定制设计（除了添加用户名），它的实现几乎是开箱即用

我读过几篇文章，其中关于iOS和CSRF令牌的问题含糊不清，但我对rails非常陌生，不知道如何解决这个问题。有人能帮忙吗

更新：

正如在帖子中建议的那样，我在application\u controller.rb中注释掉了

protect\u from\u fraze

，并在application.html.erb中注释掉了

csrf\u meta\u标记。
另外，我在config/session\u store.rb中添加了
：domain=>：all

没有任何帮助。显然，我不再收到
无法验证CSRF令牌真实性的错误，但以下日志：

有人有主意吗？
我也有同样的错误，我在Heroku的日志中看到了同样的生产症状：


警告：无法验证CSRF令牌的真实性
以及尝试登录后的401未经授权重定向

我的解决方案是将
domain:：all
添加到
config/initializers/session_store.rb中的
session_store
，检查这个：似乎相关。
