我已经添加了所需的Rack :: Test :: Methods来获取last_response方法,但它似乎没有正常工作. last_response总是似乎告诉我sign_in页面,即使我已经登录.

如果我删除Rack :: Test ::方法last_response消失,我可以使用响应,我得到当前的响应.一切似乎都行.

为什么是这样？响应方法来自哪里？可以使用响应来获取会话的上一个响应吗？

我需要使用last_response或类似的东西

last_response.headers["Location"].should eql(route)

所以我可以匹配路线.如果不是这样,我将被设置.
