redux에서 약속 한대로이 웹 소켓을 어떻게 변환 할 수 있습니까? 이 라이브러리 https://www.npmjs.com/package/websocket-as-promised을 사용하고 싶었지만 이것을 weksocket에서 구현하는 방법을 모르겠습니다.웹 소켓은 redux 용으로 약속 됨
귀하의 도움이 필요합니다 PLEASEEE.
은 REDUX위한이 웹 소켓은 "exec64"에 의해 만들어지고 내 응용 프로그램의 기능이다 그러나 나는 약속을 반납하고자하고있다.

**하지만 작동하지 :
내가 설치하고 약속 웹 소켓 -로 - 라이브러리 (https://www.npmjs.com/package/websocket-as-promised)를 가져올 시도, 나는 내 웹 소켓에 바로이 코드를 교체 **
socket = new WebSocketAsPromised(action.url);
