オブジェクトのタグ付けの設定 - Object Storage Service - Alibaba Cloud ドキュメントセンター

Object Storage Service (OSS) では、オブジェクトタグを設定してオブジェクトを分類できます。ライフサイクルルールを設定し、タグに基づいてオブジェクトへのアクセスを制御できます。

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。
オブジェクトにタグを追加するには、oss:PutObjectTagging権限が必要です。詳細については、「RAMユーザーへのカスタムポリシーのアタッチ」をご参照ください。
