Go 1.7 or above

설치

go get -u github.com/CDNetworks-Object-Storage/wcs-go-sdk-v2/wos

초기화

WosClient(WOS 클라이언트)는 CDNetwork Object Storage 에 접속하기 위한 Go 클라이언트입니다. 호출자가 WOS 서비스와 상호 작용하고 Object Storage 에 있는 버킷 및 객체와 같은 리소스를 관리하고 운영할 수 있도록 다양한 인터페이스를 제공합니다.
WOS Go SDK를 사용하여 요청(Request)하려면 WosClient 인스턴스를 초기화하고 필요에 따라 클라이언트 설정 파라미터를 조정해야 합니다.

wosClient를 생성합니다

var ak = "*** Provide your Access Key ***" var sk = "*** Provide your Secret Key ***" var endpoint = "https://your-endpoint" var regionName = "your-regionName" wosClient, err := wos.New(ak, sk, endpoint, wos.WithRegion("your-region")) if err == nil { // Use wosClient to access Object Storage // ... // Close wosClient wosClient.Close() } else { // Parse error code and message from the API response if wosError, ok := err.(wos.WosError); ok { fmt.Println(wosError.StatusCode) fmt.Println(wosError.Code) fmt.Println(wosError.Message) } else { fmt.Println(err) } }

설정

클라이언트를 생성할 때 파라미터를 사용하여 다른 클라이언트 설정을 지정할 수 있습니다. 예를 들어 응답 헤더 검색 시간 제한을 30초로 설정합니다.

wosClient, err := wos.New(ak, sk, endpoint, wos.WithHeaderTimeout(30))
