How to POST content with an HTTP Request (Perl) - perl

Question

use LWP::UserAgent;
use Data::Dumper;
my $ua = new LWP::UserAgent;
$ua->agent("AgentName/0.1 " . $ua->agent);
my $req = new HTTP::Request POST => 'http://example.com';
$req->content('port=8', 'target=64'); #problem
my $res = $ua->request($req);
print Dumper($res->content);
How can I send multiple pieces of content using $req->content? What kind of data does $req->content expect?
It only sends the last one.
Edit:
Found out if i format it like 'port=8&target=64' it works. Is there a better way?

Answer 1

my $ua = LWP::UserAgent->new();
my $request = POST( $url, [ 'port' => 8, 'target' => 64 ] );
my $content = $ua->request($request)->as_string();

Answer 2

The answer given didn't work for me. I still had the same problem as OP.
The documentation for LWP::UserAgent wants a hash or array reference.
This works:
my $url = 'https://www.google.com/recaptcha/api/siteverify';
my $ua = LWP::UserAgent->new();
my %form;
$form{'secret'}='xxxxxxxxxxxxxxxxxxxxxxx';
$form{'response'}=$captchaResponse;
my $response = $ua->post( $url, \%form );
my $content = $response->as_string();

Answer 3

Using together LWP::UserAgent and HTTP::Request as it is also quite common if not even more frequent practice , I was little puzzled that the standard POST and GET / request were almost not discussed at SO aside from json as them are in vast majority used.
POST
my $ua = LWP::UserAgent->new();
my $req = new HTTP::Request(
'POST' => "http://url/path",
['Content-Type' => 'application/x-www-form-urlencoded; charset=UTF-8'],
'par1=par1value&par2=par2value'
);
$ua->request($req);
similarly for the GET
my $ua = LWP::UserAgent->new();
my $req = new HTTP::Request(
'GET' => "http://url/path",
['Content-Type' => 'application/x-www-form-urlencoded; charset=UTF-8'],
'par1=par1value&par2=par2value' # or I presume attaching the query string directly to the url
);
$ua->request($req);
another format form , where the first two parameters (method and url) are not fused into a one, not like the previous, but separately
my $request = HTTP::Request->new( 'POST', $url, [ parameter1 => 'parameter1Value' ] );
request->header( 'Content-Type' => 'application/json' )
There is a similar question, but just regards LWP and Json, but it could be probably accomplished only by using both LWP and HTTP::Request together as suggested by that question chosen answer, and the POST and GET were missing there but it might not have been obvious
How can I make a JSON POST request with LWP?
Note:
I post this specially also, since the concrete/concise usage for POST/GET is not mentioned even in the documentation
