如何使用「redirect_to」刪除請求的子域名？

Question

如果我訪問http://walmart.example-site.com
它重定向我http://walmart.example-site.com/communities/walmart

但我想它重定向到http://example-site.com/communities/walmart

我該如何解決？

我的代碼。

的routes.rb

constraints(:subdomain => /.+/) do 
    root :to => 'communities#subdomain_redirect' 
end 

communities_controller.rb

def subdomain_redirect 
    @community = Community.find_by_community_name(request.subdomain) 
    redirect_to @community 
end 

Answer 1

match "/stories/:name" => redirect {|params| "/posts/#{params[:name].pluralize}" } 
match "/stories" => redirect {|p, req| "/posts/#{req.subdomain}" } 

是這是你需要的？嘗試參考secion 3.12重定向下的官方路由指南。
