【问题描述】：

我有这条路线可以让我为像这样的用户构建自定义 url /thisismyname，它工作正常。但是当我查看日志时我不喜欢的东西...

当我点击 /gregory 这就是发生的事情： 1. 前往 public_profile#public # 好 2. 点击 /assets 并尝试使用资产令牌找到用户 # 不好

我认为我的限制可以避免这种情况，但似乎不是这样......

class PublicProfileConstraint
  def self.matches?(request)
     !['assets', 'admin'].include?(request.session[:token])
  end
end

get "/:token" => "profiles#public", :as => :public_profile,
    :constraints => PublicProfileConstraint

这是日志：

【问题讨论】：

你能说一下为什么你不想要这些东西并详细说明你想要做什么吗？如果你这样做，也许我可以帮忙。
我不想要这个，因为 /assets 是资产管道的路径。在我的情况下，它会触发我的 profile#public 操作并尝试使用“资产”令牌查找用户。

【解决方案1】：

您正在 request.session 搜索令牌，但这总是会失败，因为这是会话存储而不是请求参数。您可能希望约束类中的 params[:token] 等效。 request object documentation 表示request.path_parameters[:token] 可能包含您要查找的值。
