Etiquetado de buckets (Go SDK V1) - Object Storage Service - Centro de documentación de Alibaba Cloud

Las etiquetas le permiten marcar buckets para distintos propósitos y gestionarlos por categoría.

Notas

En este tema se utiliza el endpoint público de la región China (Hangzhou). Si necesita acceder a OSS desde otros servicios de Alibaba Cloud en la misma región que OSS, utilice un endpoint interno. Para obtener más información sobre las regiones y los endpoints de OSS, consulte Regions and endpoints.
En este tema, las credenciales de acceso se obtienen de variables de entorno. Para obtener más información sobre cómo configurar las credenciales de acceso, consulte Configure access credentials.
Este tema muestra cómo crear una instancia de OSSClient con un endpoint de OSS. Para conocer configuraciones alternativas, como usar un dominio personalizado o autenticarse con credenciales de Security Token Service (STS), consulte Configure a client (Go SDK V1).

Establecer etiquetas de bucket

A continuación se muestra cómo establecer etiquetas para un bucket llamado examplebucket.

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.
	tag1 := oss.Tag{
		Key:   "key1",
		Value: "value1",
	}
	tag2 := oss.Tag{
		Key:   "key2",
		Value: "value2",
	}
	tagging := oss.Tagging{
		Tags: []oss.Tag{tag1, tag2},
	}
	// Specify the bucket name, for example, examplebucket.
	// Set bucket tags.
	err = client.SetBucketTagging("examplebucket", tagging)
	if err != nil {
		fmt.Println("Error:", err)
		os.Exit(-1)
	}
}
