Autorisation RAM

Le tableau ci-dessous décrit les autorisations nécessaires pour appeler cette API. Vous pouvez les définir dans une politique Resource Access Management (RAM). Les colonnes du tableau sont détaillées ci-dessous :

Action : les actions peuvent être utilisées dans l'élément Action des instructions de politique de permissions RAM pour accorder les autorisations nécessaires à l'exécution de l'opération.
API : l'API que vous pouvez appeler pour exécuter l'action.
Niveau d'accès : le niveau d'accès prédéfini accordé pour chaque API. Valeurs valides : create, list, get, update et delete.
Type de ressource : le type de ressource qui prend en charge l'autorisation pour exécuter l'action. Il indique si l'action prend en charge les permissions au niveau de la ressource. La ressource spécifiée doit être compatible avec l'action. Sinon, la politique sera inefficace.
- Pour les API avec permissions au niveau de la ressource, les types de ressource requis sont marqués d'un astérisque (*). Spécifiez l'Alibaba Cloud Resource Name (ARN) correspondant dans l'élément Resource de la politique.
- Pour les API sans permissions au niveau de la ressource, la valeur All Resources est affichée. Utilisez un astérisque (*) dans l'élément Resource de la politique.
Clé de condition : les clés de condition définies par le service. La clé permet un contrôle granulaire, applicable aux actions seules ou aux actions associées à des ressources spécifiques. En plus des clés de condition propres au service, Alibaba Cloud fournit un ensemble de clés de condition communes applicables à tous les services pris en charge par RAM.
Action dépendante : les actions dépendantes requises pour exécuter l'action. Pour mener à bien l'opération, l'utilisateur RAM ou le rôle RAM doit disposer des permissions pour toutes les actions dépendantes.
