Uso de DescribeEndpoint con un SDK de AWS o la CLI

//! Describe the endpoint specific to the AWS account making the call.
/*!
  \param endpointResult: String to receive the endpoint result.
  \param clientConfiguration: AWS client configuration.
  \return bool: Function succeeded.

Ejemplo 1: Obtención de su punto de conexión de AWS actual

En el siguiente ejemplo de describe-endpoint se recupera el punto de conexión predeterminado de AWS al que se aplican todos los comandos.

aws iot describe-endpoint

Salida:

{
    "endpointAddress": "abc123defghijk.iot.us-west-2.amazonaws.com"
}

Para obtener más información, consulte DescribeEndpoint en la Guía para desarrolladores de AWS IoT.

Ejemplo 2: Obtención del punto de conexión ATS

En el siguiente ejemplo de describe-endpoint se recupera el punto de conexión de Amazon Trust Services (ATS).

aws iot describe-endpoint \
    --endpoint-type iot:Data-ATS

Salida:

{
    "endpointAddress": "abc123defghijk-ats.iot.us-west-2.amazonaws.com"
}
