REST API 제대로 알고 사용하기 : NHN Cloud Meetup

• REST(REpresentational State Transfer)

• Using all resources in web as giving URI

  

  

Structure of REST API

• Resource - URL: ex) goods, clothes, pics, ...

• Verb - HTTP method: CRUD ex) GET, POST, ...

  1. Create: POST
  2. Read: GET
  3. Update: PUT
  4. Delete: DELETE
  

• Representations

Characteristic of REST

1. Uniform Interface
2. Stateless: REST does not save and control state infos, sessions, cookies. So API server simply should control requests. It makes everything simple.
3. Cacheable: can cacheable with Last-Modified tag or E-Tag which used in HTTP protocol.
4. Self-descriptiveness(자체 표현 구조)
5. Client - Server structure: dependency between two is less and simple.
6. Layer structure: multi-layer. added security, load balancing, encryption layer.
