@zhangjingqiang 额 devise 的密码找回 需要 邮箱 回执的
Devise::PasswordsController#edit is for non-authenticated users who wish to change their password using a reset token. This reset token was previously sent to the user in an email (Reset password instructions). If the user is already logged in, this edit password page will always redirect to the after-sign-in path since it shouldn’t be accessible to authenticated users.
