JSON handling in Perl involves using specific modules to encode and decode JSON data. Two popular modules for this purpose are Cpanel::JSON::XS
and JSON::MaybeXS
. These modules provide efficient ways to serialize Perl data structures to JSON format and vice versa, making it easier to work with web APIs and data interchange formats.
Here's a simple example of using Cpanel::JSON::XS:
#!/usr/bin/perl
use strict;
use warnings;
use Cpanel::JSON::XS;
my $json = Cpanel::JSON::XS->new;
# Perl data structure
my $data = { name => "John Doe", age => 30, city => "New York" };
# Encode Perl data structure to JSON
my $json_text = $json->encode($data);
print "Encoded JSON: $json_text\n";
# Decode JSON back to Perl data structure
my $decoded_data = $json->decode($json_text);
print "Decoded Perl Data: ", $decoded_data->{name}, "\n";
