DreamT has asked for the wisdom of the Perl Monks concerning the following question:

Hi,
I have the following structure of an array:

push @params, {index_1 => "value1"}; push @params, {index_2 => "value2"};

i.e. an array of anonymous hashes. Can I post this array as POST parameters to LWP::UserAgent, or do I need to do something with it first?

Replies are listed 'Best First'.

    Here are a couple of scripts I use when playing with POSTs. They are from an ecommerce program that I used to learn Perl. I hope they help you understand what is being done in an actual POST.
    #!/usr/bin/perl use warnings; #use this to test cc transaction, it simulates the output of perlshop use warnings; use HTTP::Request::Common qw(POST); use LWP::UserAgent; $grand_total= '109.34'; $order_id= '999999999'; $street1= '9 9th Street'; $country= 'US'; $email= 'z9@z9.com'; $first= 'zjoe'; $last= 'zmon'; $card_no= '4111 1111 1111 1111'; $exp_mon= '09'; $exp_yr= '2004'; $zip= '48127'; $ua = LWP::UserAgent->new(); $req = POST 'http://zentara.zentara.net/~zentara/cgi-bin/store/respgen +.pl', ['IOC_merchant_id' => '1983645028456zz', 'IOC_order_total_amount' => "$grand_total", 'IOC_merchant_shopper_id' => 'susehost', 'IOC_merchant_order_id' => "$order_id", 'ecom_billto_postal_street_line1' => "$street1", 'ecom_billto_postal_postalcode' => "$zip", 'ecom_billto_postal_countrycode' => "$country", 'ecom_billto_online_email' => "$email", 'ecom_payment_card_name' => "$first $last", 'ecom_payment_card_number' => "$card_no", 'ecom_payment_card_expdate_month' => "$exp_mon", 'ecom_payment_card_expdate_year' => "$exp_yr", 'url' => 'http://zentara.zentara.net/~zentara/cgi-bin/shop/boacc.pl' +, ]; $content = $ua->request($req)->as_string; print $content;
    and if you want to setup a relay, you can manually construct the POST url string.
    #!/usr/bin/perl use warnings; use CGI; use LWP::UserAgent; my $test= 'TRUE'; #my test= 'FALSE'; my $relay; my $cgi = new CGI; my %input= $cgi->Vars(); open (TEST,"+>zrelayvars"); foreach $name (keys %input){ $value = $input{$name}; print TEST "$name=$value\n"; $relay .= "$name=$value&"; } $relay .= "Ecom_transaction_complete=$test&"; $relay .= "IOC_response_code=0&"; close TEST; my $ua = LWP::UserAgent->new(); my $req = HTTP::Request->new (POST => 'https://zentara.zentara.net/~ze +ntara/cgi-bin/shop/boacc.pl'); $req->content_type('application/x-www-form-urlencoded'); $req->content("$relay"); my $res = $ua->request($req); print $res->as_string;

    I'm not really a human, but I play one on earth.

    What happens when you try?
