HTTP
요청 규칙
HTTP
프로토콜에는 클라이언트가 서버와 통신하는 요청 규칙
request
method
(
HTTP
동사
verb
라고
도 부릅니다) 정의가 들어 있습니다. 가장 널리 쓰이는 규칙은
GET
과
POST
입니다.
브라우저에
URL
을 입력하거나 링크를 클릭하면 브라우저는 서버에
HTTP
GET
요청을 보냅니
다. 서버로 보내지는 중요한 정보는
URL
경로와 쿼리스트링입니다. 앱은 규칙, 경로, 쿼리스
트링에 따라 어떻게 응답할지 결정합니다.
웹사이트의 대부분 페이지는
GET
요청에 응답합니다.
POST
요청은 보통 서버에 정보를 보낼
때 사용합니다. 서버는 요청에 포함된 정보를 처리한 후 응답을 보내는데, 정보가
POST
요청으
로 들어왔든
GET
요청으로 들어왔든 응답
HTML
은 대개 같습니다. 브라우저는 서버와 통신할
때
AJAX
또는
GET
과
POST
만 사용합니다.
반면 웹 서비스는
HTTP
규칙을 좀 더 창의적으로 쓸 때가 많습니다. 예를 들어
API
호출을 통
해 뭔가를 지울 때 유용한
DELETE
라는
HTTP
규칙이 있습니다.
노드와 익스프레스를 쓸 때는 어떤 요청에 응답할지가 완전히 자유입니다(개중에는 널리 쓰이
지 않아서 잘 지원되지 않는 것도 물론 있습니다). 익스프레스에서는 보통 핸들러를 통해 요청
에 응답합니다.
