Ruby on rails 双令牌签入装置

当用户试图在我们的项目中创建一个新用户时，Desive每天第一次表现得很怪异。这是用户单击确认链接时的服务器日志：

验证令牌被检查两次。我正在覆盖我的用户模型中的confirm函数。这就是问题所在吗？守则：

  def confirm!
    super
    send_welcome_mail
  end

---

这两个请求似乎来自两个不同的IP：

199.116.169.254

vs

201.234.55.21

。有什么想法吗？哦，这很奇怪，是同一个用户。事实上，用户就是我们的测试人员。他在办公室工作。我还得到了几天前的日志，这是我对同一个用户做了同样的测试后得到的，ip是一样的。你能解释一下吗？我无法解释：（你解决了这个问题吗？我注意到第一个

GET”/users/confirmation请求导致了重定向（302）到
/users/sign_in
而第二个没有。除了前面评论中讨论的不同IP之外，第一个GET/redirect/GET请求是
as*/*
和第三个请求（第二个
GET”/users/confirmation？..
请求）
是否为HTML
，这似乎有点奇怪。这两个请求是否都来自于单击确认链接？
