Question

我是rails和heroku的新手，并创建了一个基本的应用程序。在过去的几周里，我一直只使用1个dyno在Heroku中玩耍。现在我已经增加到两个并且遇到了CSRF错误，因为一旦第二个dyno涉及到，就会重置真实性令牌。至少这是我的想法。但我还在学习。

我在播客等方面听过很多关于Resque，Sidekiq，memcached和dalli的消息。这是我需要去学习的东西，所以我可以弄清楚如何坚持这个用户会话为什么有多个dynos。

这是an early question的后续内容，但我不确定它们是否相关。此外，我正在与错误的乘客一起跑。

Answer 1

我也有这个问题，设计3.2.4，rails 4.0.5和独角兽。

我生成并将秘密令牌存储到磁盘。但每个heroku dyno都有自己的文件系统，因此两个dynos都有自己的秘密令牌。当请求转到另一个dyno时，它使用了另一个秘密令牌并且会话被杀死了。

令牌必须存储到env变量并从secret_token.rb中使用，如下所示：

YourApp::Application.config.secret_key_base = ENV['SECRET_TOKEN']

生成令牌

rake secret

并设置

heroku config:set SECRET_TOKEN=yourtoken

从1 Dyno增加到2会产生authenticity_token错误
