    Autorização RAM

    A tabela abaixo descreve a autorização necessária para chamar esta API. Você pode defini-la em uma política do Resource Access Management (RAM). As colunas da tabela estão detalhadas abaixo:

    • Ação: As ações que podem ser usadas no elemento Action das instruções de política de permissão do RAM para conceder permissões para executar a operação.

    • API: A API que você pode chamar para executar a ação.

    • Nível de acesso: O nível de acesso predefinido concedido para cada API. Valores válidos: create, list, get, update e delete.

    • Tipo de recurso: O tipo de recurso que suporta autorização para executar a ação. Indica se a ação suporta permissão em nível de recurso. O recurso especificado deve ser compatível com a ação. Caso contrário, a política será ineficaz.

      • Para APIs com permissões em nível de recurso, os tipos de recursos obrigatórios são marcados com um asterisco (*). Especifique o Nome de Recurso Alibaba Cloud (ARN) correspondente no elemento Resource da política.

      • Para APIs sem permissões em nível de recurso, é exibido como Todos os Recursos. Use um asterisco (*) no elemento Resource da política.

    • Chave de condição: As chaves de condição definidas pelo serviço. A chave permite controle granular, aplicando-se somente a ações ou a ações associadas a recursos específicos. Além das chaves de condição específicas do serviço, o Alibaba Cloud fornece um conjunto de chaves de condição comuns aplicáveis a todos os serviços compatíveis com RAM.

    • Ação dependente: As ações dependentes necessárias para executar a ação. Para concluir a ação, o usuário RAM ou a função RAM deve ter permissões para executar todas as ações dependentes.
