ActionController::RoutingError（没有路线匹配 [GET]）亚马逊 EC2 生产

Question

我已经使用 nginx 和 passenger 在 amazon ec2 实例上部署了我的应用程序，并且在我调用 api.subdomain.domain.com/admin 时它的工作正常并且它的工作非常完美，正如我想要的运行。

但是当我调用 url api.subdomain.domain.com/v1/products 时，我遇到了以下错误。它在本地开发和生产模式上都能正常工作。只有 API 呼叫不工作。

我用过ruby 2.2.2和rails 4.2.3。

如果有人想了解有关此问题的更多详细信息，请告诉我。

我的 routes.rb 文件：

Rails.application.routes.draw do
  devise_for :admin_users, ActiveAdmin::Devise.config
  ActiveAdmin.routes(self)

  constraints :subdomain => 'api' do
    namespace :api, path: nil, defaults: {format: 'json'} do
      namespace :v1 do
        get "/products" => "products#all_details"
      end

      namespace :v2 do
        get "/products" => "products#all_details"
      end
    end
  end
end

当我做rake路线时，我得到了这条路线

api_v1_products GET        /v1/products(.:format)                    api/v1/products#all_details {:subdomain=>"api", :format=>"json"}

我已经找到解决办法了。这里的问题是针对子域的。在这里我确实有 2 个子域和 rails 默认情况下将 1 设置为 TLD(Top Level Domain)。我将它增加了 2，它对我有用。

此处设置 2 作为值，我在 production.rb

上添加了以下配置

config.action_dispatch.tld_length = 2

注意：实际上 TLD 不用于前子域，但它对我有用，所以我在这里给出了解决方案。它用于 .com、.co.in..
