Hi all,
Would really appreciate your help. This is probably more of a Perl /
SOAP than adwords API question, but I've spent hours trawling the
internet for an answer to this and cannot find it, so I'm hoping you
can help :). I'm relatively new to Perl and SOAP, and I'm trying to
implement a connection to the Google Adwords API using SOAP::Lite. I
have it almost working but however I try and get a return value from
SOAP::SOM (e.g. using valueof or result) I only seem to get the last
element. Even calling valueof("//Body") just gives me one element. I
have tried debugging the code and using Dumper, but the SOAP::Lite
code is quite unreadable (at least to me :)
and I can't work out whats going on. I've tried implementing this
directly both using SOAP::Lite and via Google::Adwords, and they both
have the same behaviour.
This what I get from valueof("//Body):
$VAR1 = {
'getKeywordVariationsResponse' => {
'getKeywordVariationsReturn' => {
'moreSpecific' => {
'searchVolumeScale' => '2',
'language' => '',
'text' => 'trusted places 1',
'advertiserCompetitionScale' => '3'
}
}
}
};
But I know there is more than one KeywordVariation from using Dumper
on the SOAP::SOM object.
This is the code I am using, its basically the example provided by
Google:
use strict;
use warnings;
use English '-no_match_vars';
use SOAP::Lite;
use Data::Dumper;
binmode(STDOUT, ':utf8');
# Provide AdWords login information.
my $email = '';
my $password = '';
my $client_email = '[email protected]';
my $useragent = 'QYPE: AdWords API Perl Sample Code';
my $developer_token = '[email protected]++usd';
my $application_token = 'INSERT_APPLICATION_TOKEN_HERE';
# Set up service connection with autotyping disabled and fault handler
# registered. To send requests to production environment, replace
"sandbox" with
# "adwords". To view XML request/response, uncomment
# "SOAP::Lite->import(+trace => 'debug');".
my $url =
sprintf('https://%s.google.com/api/adwords/v12/KeywordToolService',
'sandbox');
my $wsdl = $url . '?wsdl';
my $service =
SOAP::Lite->service($wsdl)->autotype(0)->readable(1)->proxy($url);
$service->on_fault(sub {
my $response = $ARG[1];
die('The following SOAP fault occurred:', "\n",
' faultcode: ', $response->faultcode(), "\n",
' faultstring: ', $response->faultstring(),
"\n")
});
SOAP::Lite->import(+trace => 'debug');
# Define SOAP headers.
my @headers = (
SOAP::Header->name('email' => $email),
SOAP::Header->name('password' => $password),
SOAP::Header->name('clientEmail' => $client_email),
SOAP::Header->name('useragent' => $useragent),
SOAP::Header->name('developerToken' => $developer_token),
SOAP::Header->name('applicationToken' => $application_token)
);
# Create seed keyword structure.
my $seed_keyword = {
'negative' => 'false',
'text' => 'trusted places',
'type' => 'Broad',
};
my $seed_keywords = SOAP::Data->name('seed_keywords' =>
[$seed_keyword]);
my $use_synonyms = SOAP::Data->name('useSynonyms' => 'true');
my $languages = SOAP::Data->name('languages' => ['en']);
my $countries = SOAP::Data->name('countries' => ['US']);
# Get keyword variations.
my $variation_lists = $service->call('getKeywordVariations' =>
$seed_keywords,
$use_synonyms, $languages, $countries, @headers);
print Dumper($variation_lists);
my @data = $variation_lists->valueof("//Body");
foreach my $data_word (@data){
print Dumper($data_word);
}
If anyone knows where I am going wrong I'd be most grateful!
Thanks for your help.
