Javascript SDK for Swift API

OpenStack에서 제공하는 Javascript SDK를 이용하여 네이버 클라우드 플랫폼[공공기관용] Archive Storage를 사용하는 방법을 설명합니다.

이 문서는 openstack-swift-client 2.1.0 버전을 기준으로 작성되었습니다.

설치

npm install --save openstack-swift-client@2.1.0

python-swiftclient

• 문서 : https://github.com/stefanodefaria/swift-client

예제

예제에서 사용하는 user, key는 포탈 마이페이지 > 계정 관리 > 인증키 관리 에서 생성한 API 인증키를 사용합니다. (Access Key ID는 username, Secret Key는 password)
projectId와 domainId 정보는 Archive Storage 콘솔에서 이용 신청 후 [API 이용 정보 확인] 버튼을 통해 확인할 수 있습니다.
