Mostrar el estado de validación del dominio

El siguiente ejemplo muestra cómo utilizar la función ListCertificateDomainValidations. La función devuelve una lista de resúmenes de validación de dominios, uno para cada dominio del certificado. Cada resumen contiene la configuración de validación activa y (durante una migración) la configuración de validación solicitada con el registro CNAME para añadirla a la configuración de DNS. El ejemplo muestra cómo gestionar la paginación con. NextToken
