Comentários

O Regenerate Storage Account Keys operação faz com que a chave primária ou secundária de um serviço de conta de armazenamento deverá ser regenerada. Essa operação pode ser usada com as contas de armazenamento retornadas pelo Listar contas de armazenamento operação para automatizar o gerenciamento de atualizações de chave de armazenamento.

Exemplo

O programa de exemplo a seguir usa a ID da assinatura, uma impressão digital do certificado de gerenciamento associado, a cadeia de caracteres da versão da operação e um nome de conta de armazenamento e imprime as chaves de acesso da conta de armazenamento retornadas para o console. Em seguida, ele chama o Regenerate Storage Account Keys operação para regenerar a chave de acesso secundária para a conta de armazenamento e imprime os resultados-chave novos. Inicializar o Version constante com uma cadeia de caracteres de cabeçalho de versão SubscriptionId com o identificador GUID para a assinatura, Thumbprint com o valor de impressão digital do certificado de gerenciamento, e ServiceName com o nome da sua conta de armazenamento para executar o código de exemplo.
