Rails 4跨子域的会话 [英] Rails 4 Session across subdomains

问题描述

我尝试以下，没有运气，试图在子域中持续会话：

I'm trying the following with no luck in an attempt to persist sessions across subdomains:

MyApp::Application.config.session_store :cookie_store, key: '_myapp_session', :domain => :all, :tld_length => 2

MyApp::Application.config.session_store :cookie_store, key: '_myapp_session', :domain => 'myapp.dev'

MyApp::Application.config.session_store :cookie_store, key: '_myapp_session', :domain => '.myapp.dev'

我在Google和SO上发现了所有这些组合。

I found all of these combinations on Google and SO.

我看到一些解释，但它涉及手动设置cookie。如果可能，我想坚持配置。

I saw a few explanations but it involved manually setting the cookie. I'd like to stick with configuration if possible.

注意：我正在使用devise。我还重新启动了服务器并清除了cookies。

Note: I'm using devise. I've also restarted the server and cleared cookies.

推荐答案

我发现不同的应用程序应该有相同的 secret_key_base ，位于 config / initializers / secret_token.rb 中。之后，我的所有应用程序都开始使用共享会话。

I found that different applications should have identical secret_key_base, located in config/initializers/secret_token.rb. After I did this, all my applications is started to use shared session.

PS。当然，他们应该有相同的会话密钥。

PS. Of course, they should have identical session keys.
