Paketleri farklı amaçlarla işaretlemek ve kategori bazında yönetmek için etiketlerden yararlanabilirsiniz.
Notlar
Bu konuda Çin (Hangzhou) bölgesinin genel uç noktası kullanılmıştır. OSS ile aynı bölgedeki diğer Alibaba Cloud hizmetlerinden OSS'e erişmek için dahili uç nokta kullanın. OSS bölgeleri ve uç noktaları hakkında daha fazla bilgi için bkz. Bölgeler ve uç noktalar.
Bu konuda erişim kimlik bilgileri ortam değişkenlerinden alınır. Erişim kimlik bilgilerinin nasıl yapılandırılacağı hakkında daha fazla bilgi için bkz. Erişim kimlik bilgilerini yapılandırma.
Bu konu, bir OSS uç noktası kullanarak bir OSSClient örneğinin nasıl oluşturulacağını gösterir. Özel alan adı kullanma veya Security Token Service (STS) kimlik bilgileriyle kimlik doğrulama gibi alternatif yapılandırmalar için bkz. İstemciyi yapılandırma (Go SDK V1).
Paket etiketlerini ayarlama
Aşağıdaki kod, examplebucket adlı bir paket için etiketlerin nasıl ayarlanacağını gösterir.
package main
import (
"fmt"
"os"
"github.com/aliyun/aliyun-oss-go-sdk/oss"
)
func main() {
// Obtain access credentials from environment variables. Before you run this sample code, make sure that the OSS_ACCESS_KEY_ID and OSS_ACCESS_KEY_SECRET environment variables are set.
provider, err := oss.NewEnvironmentVariableCredentialsProvider()
if err != nil {
fmt.Println("Error:", err)
os.Exit(-1)
}
// Create an OSSClient instance.
// Set yourEndpoint to the Endpoint of your bucket. For example, for the China (Hangzhou) region, set the Endpoint to https://oss-cn-hangzhou.aliyuncs.com. For other regions, use the actual Endpoint.
// Set yourRegion to the region where your bucket is located. For example, for the China (Hangzhou) region, set the region to cn-hangzhou. For other regions, use the actual region.
clientOptions := []oss.ClientOption{oss.SetCredentialsProvider(&provider)}
clientOptions = append(clientOptions, oss.Region("yourRegion"))
// Set the signature version.
clientOptions = append(clientOptions, oss.AuthVersion(oss.AuthV4))
client, err := oss.New("yourEndpoint", "", "", clientOptions...)
if err != nil {
fmt.Println("Error:", err)
os.Exit(-1)
}
// Initialize tags.
