NAME¶
Mojo::JSON - Minimalistic JSON
SYNOPSIS¶
# Encode and decode JSON
use Mojo::JSON;
my $json = Mojo::JSON->new;
my $bytes = $json->encode({foo => [1, 2], bar => 'hello!', baz => \1});
my $hash = $json->decode($bytes);
# Check for errors
my $json = Mojo::JSON->new;
if (defined(my $hash = $json->decode($bytes))) { say $hash->{message} }
else { say 'Error: ', $json->error }
# Use the alternative interface
use Mojo::JSON 'j';
my $bytes = j({foo => [1, 2], bar => 'hello!', baz => \1});
my $hash = j($bytes);
DESCRIPTION¶
Mojo::JSON is a minimalistic and relaxed implementation of RFC 4627. While it is
possibly the fastest pure-Perl JSON parser available, you should not use it
for validation.
It supports normal Perl data types like "Scalar", "Array"
reference, "Hash" reference and will try to call the
"TO_JSON" method on blessed references, or stringify them if it
doesn't exist.
[1, -2, 3] -> [1, -2, 3]
{"foo": "bar"} -> {foo => 'bar'}
Literal names will be translated to and from Mojo::JSON constants or a similar
native Perl value. In addition "Scalar" references will be used to
generate booleans, based on if their values are true or false.
true -> Mojo::JSON->true
false -> Mojo::JSON->false
null -> undef
Decoding UTF-16 (LE/BE) and UTF-32 (LE/BE) will be handled transparently,
encoding will only generate UTF-8. The two Unicode whitespace characters
"u2028" and "u2029" will always be escaped to make JSONP
easier.
FUNCTIONS¶
Mojo::JSON implements the following functions.
my $bytes = j([1, 2, 3]);
my $bytes = j({foo => 'bar'});
my $array = j($bytes);
my $hash = j($bytes);
Encode Perl data structure or decode JSON and return "undef" if
decoding fails.
ATTRIBUTES¶
Mojo::JSON implements the following attributes.
error¶
my $err = $json->error;
$json = $json->error('Parser error');
Parser errors.
METHODS¶
Mojo::JSON inherits all methods from Mojo::Base and implements the following new
ones.
decode¶
my $array = $json->decode($bytes);
my $hash = $json->decode($bytes);
Decode JSON to Perl data structure and return "undef" if decoding
fails.
encode¶
my $bytes = $json->encode([1, 2, 3]);
my $bytes = $json->encode({foo => 'bar'});
Encode Perl data structure to JSON.
false¶
my $false = Mojo::JSON->false;
my $false = $json->false;
False value, used because Perl has no native equivalent.
true¶
my $true = Mojo::JSON->true;
my $true = $json->true;
True value, used because Perl has no native equivalent.
