Question

使用rails 5试图创建一个简单的api来注册用户。

控制器：

class Api::V1::SessionsController < Devise::SessionsController
  protect_from_forgery
  respond_to :json
  skip_before_action :verify_authenticity_token #, only: [:create]

    api :POST, "/v1/create_account", "Create User Account"
    param :user, Hash do
    param :email, :undef
    param :password, :undef
  end

  def create_account
    user = params[:user]

    existing_user = User.find_by_email user[:email].strip

    return email_already_taken if !existing_user.nil?

    user = User.create(:email => user[:email],
                        :password => user[:password],
                        :password_confirmation => user[:password])
  end

end

路线：

Rails.application.routes.draw do
  devise_for :admin_users

  namespace :api, defaults: {format: "json"} do

  namespace :v1 do

  devise_for :users, :controllers => {:sessions => "api/v1/sessions"}, :path_prefix => 'api/v1'

      devise_scope :user do
        post :create_account, to: "sessions#create_account"
      end
  end
end
end

跟踪：

跟踪正在讨论控制器的api：POST部分，但为什么会出现此错误？

我该如何解决这个问题？
