Perl: SOAP::Lite

Basic Usage

my $uri   = "http://service/uri" ;
my $proxy = "https://service.provider.address/service" ;

my $client = SOAP::Lite;

$client->uri($uri);
$client->proxy($proxy);

$client->outputxml(1);

my $param = SOAP::Data->name('item' => \SOAP::Data->value(
  SOAP::Data->name('ATTR_NAME' => $_[1]),
  SOAP::Data->name('SIGN' => 'I'),
  SOAP::Data->name('OP' => 'BT'),
  SOAP::Data->name('LOW' => $low_val),
  SOAP::Data->name('HIGH' => $high_val)))
); 

my $xml = $client->call('some_func'=>$param);

Debug

To print out the request XML content:

use SOAP::Lite +trace => [ transport => sub { print $_[0]->as_string } ];

// my ($http_object) = @_;
// ref($http_object) eq "HTTP::Request" || ref($http_object) eq "HTTP::Response"
