我按照一些教程为我的应用程序创建了一个 API。我放置了从设计注册和会话控制器继承的自定义控制器。我在这里查看了大量的问题/答案，但无法解决我的问题。

我的解决方案适用于我的 Ubuntu VM，但不适用于 ec2 实例。这是新类的第一行：

class Api::V1::SessionsController < Devise::SessionsController

还有一些来自 routes.rb 的代码：

devise_for :users

namespace :api do
namespace :v1 do
 devise_scope :user do
   post 'registrations' => 'registrations#create', :as => 'register'
   post 'sessions' => 'sessions#create', :as => 'login'
   delete 'sessions' => 'sessions#destroy', :as => 'logout'
 end
 get 'tournaments' => 'tournaments#index', :as => 'tournaments'
end
end

我的自定义控制器位于 Api/V1 目录中，并且路由正确。错误是（带有一部分跟踪）：

为了让服务器运行，我必须在 applications.rb 中设置这些标志：

# Code is not reloaded between requests
config.cache_classes = false

# Full error reports are disabled and caching is turned on
config.consider_all_requests_local       = true
config.action_controller.perform_caching = false

尝试这个：

devise_scope :user do
  post 'registrations' => 'api/v1/registrations#create', :as => 'register'
  post 'sessions' => 'api/v1/sessions#create', :as => 'login'
  delete 'sessions' => 'api/v1/sessions#destroy', :as => 'logout'
end

namespace :api do
  namespace :v1 do
    get 'tournaments' => 'tournaments#index', :as => 'tournaments'
  end
end

修改routes.rb后一定要重启服务器

确保您的控制器在目录中api/v1（仅使用小写字母）
