为 API 设计路线

Question

我如何理解以下错误消息（在测试时）以及为什么在向我的注册控制器创建操作发出发布请求时，我使用的是/lnf.json？

在我的路线中，我有以下约束和路径设置

constraints(subdomain: 'api') do
  devise_for :users, path: 'lnf', controllers: { registrations: "registrations" }
end

还有我的注册控制器

class RegistrationsController < Devise::RegistrationsController
  skip_before_action :verify_authenticity_token
  respond_to :json

  def create
   super
  end

end

如果我通过 curl 向http://api.local.dev:3000/lnf.json 发出帖子请求，我会得到所需的响应。

当我想使用 Rspec 进行测试时，我有一个简单的测试设置

post :create, format: :json, :user => {user params here}

但我在运行测试时遇到错误

AbstractController::ActionNotFound:
Could not find devise mapping for path "/lnf.json?

按要求输出 Rake 路由

看起来 devise_for 路由部分需要稍微调整一下（或者为您的情况添加特殊路由 lnf aka "post '/lnf', to: 'registrations#create', defaults: {format: 'json'}" ）。 你能把'rake routes | 的输出grep devise' 命令在这里？
