创建Ruby on Rails 5 API

示例

要创建新的Rails 5 API,请打开一个终端并运行以下命令:

rails new app_name --api

将创建以下文件结构:

  create  
  create  README.rdoc
  create  Rakefile
  create  config.ru
  create  .gitignore
  create  Gemfile
  create  app
  create  app/assets/javascripts/application.js
  create  app/assets/stylesheets/application.css
  create  app/controllers/application_controller.rb
  create  app/helpers/application_helper.rb
  create  app/views/layouts/application.html.erb
  create  app/assets/images/.keep
  create  app/mailers/.keep

  create  bin/rake
  create  bin/setup
  create  config
  create  config/routes.rb
  create  config/application.rb
  create  config/environment.rb
  create  config/secrets.yml

  create  lib
  create  lib/tasks
  create  lib/tasks/.keep
  create  lib/assets

  create  log
  create  log/.keep
  create  public
  create  public/404.html
  create  public/422.html
  create  public/500.html
  create  public/favicon.ico

  create  test/fixtures
  create  test/fixtures/.keep
  create  test/controllers
  create  test/controllers/.keep
  create  test/mailers
  create  test/mailers/.keep

  create  test/models/.keep
  create  test/helpers
  create  test/helpers/.keep
  create  test/integration
  create  test/integration/.keep
  create  test/test_helper.rb
  create  tmp/cache
  create  tmp/cache/assets
  create  vendor/assets/javascripts
  create  vendor/assets/javascripts/.keep
  create  vendor/assets/stylesheets
  create  vendor/assets/stylesheets/.keep

该文件结构将在名为的新文件夹中创建app_name。它包含启动项目所需的所有资产和代码。

输入文件夹并安装依赖项:

cd app_name
bundle install

您还应该启动数据库。Rails使用SQLite作为默认数据库。要创建它,请运行:

rake db:setup

现在运行您的应用程序:

$ rails server

在打开浏览器时http://localhost:3000,您的闪亮的新(空)API应该正在运行!
