rails下当post访问某个Action此Action中不能访问session

Question

如题！

登录时：session[:vip] = Vip.find

提交留言时:$.post('leavword.json',{"content":"xxxxxx"},function(data){},'json')

后台Action leavword中访问登录时保存的session[:vip]返回nil

网上查了一下说rails的session默认保存在cookie中，难道post和get两个http方法在cookie这方面还有差异？
现在看来是post时不向服务器发送cookie内容。

使用$.get时

Answer 1

没道理吧，session 是保持在服务器端，只不过会生成一个名为 xxsessionid 的 cookie
