🟢 여기서 pong 이라는 건 직접 만들어주신건가요?? pong 이 무슨 역할하는지 궁금한데 인터넷에 검색해도 딱히 나오는게 없고 코드에서도 전체 검색했는데도 잘못 검색한건지 찾을 수가 없네요...?? 또, json은 왔던 걸 그대로 보내주는건가요??

pong은 웹소켓 자체에서 제공하는 메소드이구, 방금 대충 찾아봤는데 ping/pong을 보낼 때는 일반 프레임이랑 다른 프레임을 쓰는 것 같더라고요? 그래서 pong 프레임으로 데이터 보내도록 해주는 내부 메소드인 것 같습니다.
pong 데이터는 뭐 보내야할 지 모르겠어서 한투 파이썬 라이브러리 뒤져봤는데 거기서도 그냥 왔던거 그대로 보내주는 것 같아서 이렇게 구현해두었어용
