[RUBY] [Rails] Let's create a super simple Rails API

Introduction

I made a rails API, so I will leave it as a memorandum. Next time I will try to introduce API documents such as swagger

How to make Rials API

Add --api to rails new

rails new rails-test-api --api

Easy to use

Generate CRUD This time I created a bulletin board CRUD

rails generate scaffold Board title:string text:string
rails db:create
rails db:migrate

Launch application

rails s

Connect to http: // localhost: 3000/boards

Hit POST with Curl where [] is displayed

curl -X POST -H "Content-Type: application/json" -d '{"title": "test", "text": "It's a test"}' http://localhost:3000/boards

Click here for how to hit Curl (https://qiita.com/hanata-el/items/d96d84d1889b495aca00)

Data is created when you connect to http: // localhost: 3000/boards again

[{"id":1,"title":"test","text":"It's a test","created_at":"2020-12-24T17:27:15.312Z","updated_at":"2020-12-24T17:27:15.312Z"}]

This completes
