Sample Zone Commands

Here’s a PERL example using SOAP::WSDL and the libraries from wsdl2perl.pl to:

Log in to the API to establish a Session [SessionLogin]
Get a List of existing Zones [GetZones]
Create a new zone [CreateZone]
Add A Records and MX Records [CreateARecord CreateMXRecord]
Create a new node with an A record [CreateARecord]
Publish the Zone [PublishZone]
Logout [SessionLogout]

Get Message Info

A <msgs> element is a list of zero or more messages with sub-elemnts

SOURCE: A debugging field. If reporting an error to your Dynect Concierge, be sure to include this.
LEVEL: The severity of the message. One of: ‘FATAL’, ‘ERROR’, ‘WARN’, or ‘INFO’
INFO: The actual message itself.
ERR_CD: An error code (if appropriate) regarding the message.

Here’s an example of a Perl utility function to take a response and gather
info from each of the messages element (uses SOAP::WSDL get_DATA methods)

sub output_messages {
	my $response = shift;
	
	print "Got a status code of " . $response->get_status();

	# grab a reference to the list of messages
	my $messages = $response->get_msgs();

	foreach $message (@$messages) {
		print "message:";
		print "  source: " . $message->get_source();
		print "  lvl: " . $message->get_lvl();
		print "  info: " . $message->get_info();
		print "  err_cd: " . $message->get_err_cd() if $message->get_err_cd();
	}
}

In the case of a successful call, the <msgs> will contain only one element,
SOAP::WSDL helpfully flatten this for you, so you can access the message INFO thusly:

$result->get_msgs()->get_info();

or

my $messages = $response->get_msgs();
$message->get_info();
