Listando o status de validação do domínio

O exemplo a seguir mostra como usar a função ListCertificateDomainValidations. A função retorna uma lista de resumos de validação de domínio, um para cada domínio no certificado. Cada resumo contém a configuração de validação ativa e (durante uma migração) a configuração de validação solicitada com o registro CNAME para adicionar à sua configuração de DNS. O exemplo mostra como lidar com a paginação com. NextToken
