バケットタグの管理 - Object Storage Service - Alibaba Cloud ドキュメントセンター

タグを使用して、さまざまな目的で使用されるObject Storage Service (OSS) バケットを識別し、これらのバケットを管理できます。

使用上の注意

このトピックでは、中国 (杭州) リージョンのパブリックエンドポイントを使用します。 OSSと同じリージョンにある他のAlibaba CloudサービスからOSSにアクセスする場合は、内部エンドポイントを使用します。 OSSリージョンとエンドポイントの詳細については、「リージョン、エンドポイント、オープンポート」をご参照ください。
このトピックでは、アクセス資格情報は環境変数から取得します。アクセス資格情報の設定方法の詳細については、「アクセス資格情報の設定」をご参照ください。
このトピックでは、OSSエンドポイントを使用してOSSClientインスタンスを作成します。カスタムドメイン名またはSTS (Security Token Service) を使用してOSSClientインスタンスを作成する場合は、「初期化」をご参照ください。

バケットのタグの設定

次のサンプルコードは、examplebucketという名前のバケットのタグを設定する方法の例を示しています。

package main

import (
	"fmt"
	"os"

	"github.com/aliyun/aliyun-oss-go-sdk/oss"
)

func main() {
	// Obtain access credentials from environment variables. Before you run the sample code, make sure that the OSS_ACCESS_KEY_ID and OSS_ACCESS_KEY_SECRET environment variables are configured. 
	provider, err := oss.NewEnvironmentVariableCredentialsProvider()
	if err != nil {
		fmt.Println("Error:", err)
		os.Exit(-1)
	}

	// Create an OSSClient instance. 
	// Specify the endpoint of the region in which the bucket is located. For example, if the bucket is located in the China (Hangzhou) region, set the endpoint to https://oss-cn-hangzhou.aliyuncs.com. Specify your actual endpoint. 
	// Specify the region in which the bucket is located. For example, if the bucket is located in the China (Hangzhou) region, set the region to cn-hangzhou. Specify the actual region.
	clientOptions := []oss.ClientOption{oss.SetCredentialsProvider(&provider)}
	clientOptions = append(clientOptions, oss.Region("yourRegion"))
	// Specify the version of the signature algorithm.
	clientOptions = append(clientOptions, oss.AuthVersion(oss.AuthV4))
	client, err := oss.New("yourEndpoint", "", "", clientOptions...)
	if err != nil {
		fmt.Println("Error:", err)
		os.Exit(-1)
	}

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

バケットのタグを照会する

次のサンプルコードは、examplebucketという名前のバケットのタグを照会する方法の例を示しています。

package main

import (
	"fmt"
	"os"

	"github.com/aliyun/aliyun-oss-go-sdk/oss"
)

func main() {
	// Obtain access credentials from environment variables. Before you run the sample code, make sure that the OSS_ACCESS_KEY_ID and OSS_ACCESS_KEY_SECRET environment variables are configured. 
	provider, err := oss.NewEnvironmentVariableCredentialsProvider()
	if err != nil {
		fmt.Println("Error:", err)
		os.Exit(-1)
	}

	// Create an OSSClient instance. 
	// Specify the endpoint of the region in which the bucket is located. For example, if the bucket is located in the China (Hangzhou) region, set the endpoint to https://oss-cn-hangzhou.aliyuncs.com. Specify your actual endpoint. 
	// Specify the region in which the bucket is located. For example, if the bucket is located in the China (Hangzhou) region, set the region to cn-hangzhou. Specify the actual region.

	clientOptions = append(clientOptions, oss.Region("yourRegion"))
	// Specify the version of the signature algorithm.
	clientOptions = append(clientOptions, oss.AuthVersion(oss.AuthV4))
	client, err := oss.New("yourEndpoint", "", "", clientOptions...)
	if err != nil {
		fmt.Println("Error:", err)
		os.Exit(-1)
	}

	// Specify the name of the bucket. 
	// Query the tags configured for the bucket. 
	ret, err := client.GetBucketTagging("examplebucket")
	if err != nil {
		fmt.Println("Error:", err)
		os.Exit(-1)
	}
	// Display the number of returned tags. 
	fmt.Println("Tag length: ", len(ret.Tags))
}

	clientOptions = append(clientOptions, oss.AuthVersion(oss.AuthV4))
	client, err := oss.New("yourEndpoint", "", "", clientOptions...)
	if err != nil {
		fmt.Println("Error:", err)
		os.Exit(-1)
	}

	// Query buckets by specifying the TagKey parameter. 
	ret, err := client.ListBuckets(oss.TagKey("yourTaggingKey"))
	if err != nil {
		fmt.Println("Error:", err)
		os.Exit(-1)
	}
	// Display the information about the buckets. 
	for _, bucket := range ret.Buckets {
		fmt.Println("bucket:", bucket)
	}
	// Query buckets by specifying the TagKey and TagValue parameters. 
	// The TagValue parameter can only be specified together with the TagKey parameter, or can be left empty. If you do not specify the TagValue parameter, buckets are listed based on only the TagKey parameter. 
	res, err := client.ListBuckets(oss.TagKey("yourTaggingKey"), oss.TagValue("yourTaggingValue"))
	if err != nil {
		fmt.Println("Error:", err)
		os.Exit(-1)
	}
