HTTP Host Header

fetch를 하는데 cors 에러 발생

A Host header field must be sent in all HTTP/1.1 request messages. A 400 (Bad Request) status code will be sent to any HTTP/1.1 request message that lacks a Host header field or contains more than one.

• 원인: API 서버가 HTTP/1.1을 사용하고 있어 fetch를 할 때 header에 host 명시해줘야함
