    Object Storage Service:オブジェクトのタグ付けの設定

    最終更新日:Dec 10, 2024

    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。

    説明

    オブジェクトタグの詳細については、「オブジェクトタグ付け」をご参照ください。

    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、「リージョンとエンドポイント」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Security Token Service (STS) を使用してOSSClientを作成する場合は、「OSSClientインスタンスの作成」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。

    オブジェクトをコピーするときにオブジェクトにタグを追加する

    次のいずれかの方法を使用して、オブジェクトをコピーするときにオブジェクトのタグ付けを設定できます。

    • コピー: ソースオブジェクトのタグがコピー先オブジェクトにコピーされます。

    • 置換: ターゲットオブジェクトには、ソースオブジェクトのタグではなく、リクエストで指定されたタグがあります。

    次の例では、シンプルコピーモードで1 GB未満、マルチパートコピーモードで1 GBを超えるオブジェクトにタグを追加する方法について説明します。
