p we

config/application.rb 更新后的代码

require_relative 'boot'

require 'rails/all'

# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(*Rails.groups)

module Version0
  class Application < Rails::Application
    # Initialize configuration defaults for originally generated Rails version.
    config.load_defaults 5.1
    config.eager_load_paths << Rails.root.join('app/services')
    # Settings in config/environments/* take precedence over those specified here.
    # Application configuration should go into files in config/initializers
    # -- all .rb files in that directory are automatically loaded.
  end
end

推荐答案

你可以在 app 文件夹中创建 service 文件夹，也可以使用 lib 文件夹，也可以创建一个任务.

You can create service folder in the app folder nor can use lib folder, also make a task too.

确保重启服务器和url-address！

Make sure restart the server and url-address!

#|- app
#|-- services
#|--- restdb_api.rb


require 'rest-client'
require 'json'

class RestdbApi

    def initialize
      @url = 'https://xxxx.restdb.io/rest/data'
      @headers = {
        'content-type': "application/json",
        'x-apikey': "-------",
        'cache-control': "no-cache"
      }
    end    

    def call
        res = RestClient.get(@url, @headers)
        body = JSON.parse(res, { symbolize_names: true })
        body
    end
end

# config/application.rb
   config.eager_load_paths << Rails.root.join('app/services')

并在控制器的任何地方调用它...

And call it anywhere in the controller...

#if wanna dynamically call url, api key or smth else, just initialize in the class.
rdb = RestdbApi.new
body = rdb.call
puts body
