Question

我的routes.rb

中有以下内容

  constraints subdomain: 'api' do
    namespace :api, path: nil, defaults: {format: 'json'} do
      namespace :v1 do
        resources :cities, only: [:index] do
          resources :areas, only: [:index]
        end
      end
    end
  end

已在本地测试并且可以正常工作，但是当我部署到heroku时，我收到以下错误：

Answer 1

Heroku上的主机是否设置为api.yourdomain，或者您使用的是subdomain.herokuapp.com主机？

如果子域名不是api，则此行会导致您的路由失败：

constraints subdomain: 'api' do

Heroku路由错误：ActionController :: RoutingError
