Convert::PerlRef2String Description

Converting Perl references to compressed string and vice versa Convert::PerlRef2String is a Perl module for converting PERL references to compressed string and vice versa.SYNOPSISThe following script use Convert::PerlRef2String; #Sender's action: use Data::Dumper; my $perl = { 'Order' => { 'BookName' => 'Programming Web Serivices with Perl', 'Id' => '0-596-00206-8', 'Quantity' => '500' }, 'Payment' => { 'CardType' => 'VISA', 'ValidDate' => '12-10-2006', 'CardNo' => '1234-5678-9012-3456', 'Bearer' => 'Kai Li' } }; my $string = perlref2string($perl); print $string," "; #sending the string over the Internet... #Receiver's action: my $perlref = string2perlref($string); print Dumper($perlref);produces this output: H4sIAAAAAAAAA32RzarCQAxG9z5FFheycSCttiqi4M9GFK1XqetoBx20rYyjUqTvbtVeuYJtlplz vknIj9/7taADtwq8C2c6kBqh0/1ofxT243g/5VA+MfR0vNUchirawkquYSG1uqiNPMFVmR14Uh+w Wpg1Cl4pJJyWK4hsckWzhJ+fOTLKJC/LIcLvaPo/Aj1OQhmZ8r0ybsA6WCbHfDN/tOgVj5LhPh9U MGST85YtLBI2kVtqPT6Zxn9KrS4ct9EULcr0Wt0pd/uSdX4fHLOCicIiOn0/pO3KHXfoF8XsAQAA $VAR1 = { 'Order' => { 'BookName' => 'Programming Web Serivices with Perl', 'Id' => '0-596-00206-8', 'Quantity' => '500' }, 'Payment' => { 'CardType' => 'VISA', 'ValidDate' => '12-10-2006', 'CardNo' => '1234-5678-9012-3456', 'Bearer' => 'Kai Li' } };While a slightly different version (passing PERL code to sunroutine perlref2string instead of reference) use Convert::PerlRef2String; #Sender's action: use Data::Dumper; my $perl = q|{ 'Order' => { 'BookName' => 'Programming Web Serivices with Perl', 'Id' => '0-596-00206-8', 'Quantity' => '500' }, 'Payment' => { 'CardType' => 'VISA', 'ValidDate' => '12-10-2006', 'CardNo' => '1234-5678-9012-3456', 'Bearer' => 'Kai Li' } };|; my $string = perlref2string($perl); print $string," "; #sending the string over the Internet... #Receiver's action: my $perlref = string2perlref($string); print Dumper($perlref);produces essentially the same result.When the reference contains more sophiscated data elements (for example subroutines) we prefer to send the original code over the Internet so we must use subroutine string2perlcode instead of string2perlref. The follwing script use Convert::PerlRef2String; #Sender's action: my $perlref = q|{ "Skipper" => sub{ my $person = shift; print "Kipper: Hey there, $person!

"; } }, "Professor" => sub{ my $person = shift; print "Professor: By my calculations, you must be $person! "; }, "Ginger" => sub{ my $person = shift; print "Ginger: (in a sulty voice) Well hello, $person! "; }, };|; my $string = perlref2string($perlref); print $string," "; #sending the string over the Internet... #Receiver's action: my $perlcode = string2perlcode($string); print $perlcode; my $greets = eval($perlcode); my @room; for my $person(qw(Gilligan Skipper Professor Ginger)){ print " "; print "$person walks into the room.

Strong encryption is recommended (for example SSL) and client/server certificates should be installed at the two parts to ensure a protected and exclusive channel. Requirements: · Perl
