Unity에서 Firebase Storage 사용해보기

사전 준비

에셋설치

유니티 코드

Firabase Storage API

175메가를 업로드 시켜보았다.

업로드 완료할 때까지 대략 10분 정도 걸린 것 같다.

또한, GC 로그가 지속적으로 찍혔다.

어쨋든, 업로드 잘 되었다.

직접 파일을 다운로드해서 용량을 확인해 봤다.

정확히 일치한다.

다운로드 받을 때, GetBytesAsync(maxAllowedSize) 함수에 1KB만큼 넣고 시도했다.

결과는 메모리 부족으로 받지 못했다.

이번에는 200MB를 넣고 다시 시도했다.

GC가 지속적으로 찍힌 후, 완료되었다.

데이터 지우기는 무난히 성공했다.

데이터 지우기를 한번 더 했더니, 없는 파일이라고 예외가 발생했다.

정상적으로 동작하는군.
