如何在接受？page = param的rails中形成相关的规范网址？

Question

由于问题的简单性，我试图避免使用gem。

我的网站具有以下？params =

"type" just filters by type. if this isnt specified they're all lumped together
"sort" sorts by date/whats hot/latest
"view" changes compact view/list view
"scroll" isnt even used yet, its for infinite scroll on or off which i havent put in yet
"reset" is a link when you click the logo (not the home link) that resets all session params to "all" and "whats hot" (the default)
"page" is the pagination which i think is the only really important one

在获得一些帮助之后，我被告知?page=是唯一真正重要的帮助，因为我的所有内容都可以访问而无需任何查询参数（分页除外）。

所以现在我有了这个：

  <link rel="canonical" href="<%= "http://#{request.host + request.fullpath}" %>">

所以我的问题是我该如何修改它，使其仅放入URL，并在？page =（如果存在）但忽略所有其他参数的情况下放入？

这似乎歪了

<link rel="canonical" href="<%= "http://#{request.host + url_for(:page => params[:page]) }" %>">
