($portfolio) = GEmySQL->get ("select * from portfolio where portfolio.id=$hashref->{portfolio_id}");

NAME
Business::OnlinePayment::HTTPS - Base class for HTTPS payment APIs SYNOPSIS
package Business::OnlinePayment::MyProcessor; use base qw(Business::OnlinePayment::HTTPS); sub submit { my $self = shift; #... # pass a list (order is preserved, if your gateway needs that) ( $page, $response, %reply_headers ) = $self->https_get( field => 'value', ... ); # or a hashref my %hash = ( field => 'value', ... ); ( $page, $response_code, %reply_headers ) = $self->https_get( \%hash ); #... } DESCRIPTION
This is a base class for HTTPS based gateways, providing useful code for implementors of HTTPS payment APIs. It depends on Net::HTTPS::Any, which in turn depends on Net::SSLeay _or_ ( Crypt::SSLeay and LWP::UserAgent ). METHODS
https_get [ \%options ] HASHREF | FIELD => VALUE, ... Accepts parameters as either a hashref or a list of fields and values. In the latter case, ordering is preserved (see Tie::IxHash to do so when passing a hashref). Returns a list consisting of the page content as a string, the HTTP response code and message (i.e. "200 OK" or "404 Not Found"), and a list of key/value pairs representing the HTTP response headers. The options hashref supports setting headers: { headers => { 'X-Header1' => 'value', ... }, } https_post [ \%options ] SCALAR | HASHREF | FIELD => VALUE, ... Accepts form fields and values as either a hashref or a list. In the latter case, ordering is preserved (see Tie::IxHash to do so when passing a hashref). Also accepts instead a simple scalar containing the raw content. Returns a list consisting of the page content as a string, the HTTP response code and message (i.e. "200 OK" or "404 Not Found"), and a list of key/value pairs representing the HTTP response headers. The options hashref supports setting headers and Content-Type: { headers => { 'X-Header1' => 'value', ... }, Content-Type => 'text/namevalue', } SEE ALSO
