NAME¶
Mojo::JSON - Minimalistic JSON
SYNOPSIS¶
use Mojo::JSON qw(decode_json encode_json);
my $bytes = encode_json {foo => [1, 2], bar => 'hello!', baz => \1};
my $hash = decode_json $bytes;
DESCRIPTION¶
Mojo::JSON is a minimalistic and possibly the fastest pure-Perl implementation
of RFC 7159 <
http://tools.ietf.org/html/rfc7159>.
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. Differentiating between strings and
numbers in Perl is hard, depending on how it has been used, a scalar can be
both at the same time. The string value has a higher precedence unless both
representations are equivalent.
[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.
true -> Mojo::JSON->true
false -> Mojo::JSON->false
null -> undef
In addition scalar references will be used to generate booleans, based on if
their values are true or false.
\1 -> true
\0 -> false
The two Unicode whitespace characters "u2028" and "u2029"
will always be escaped to make JSONP easier.
FUNCTIONS¶
Mojo::JSON implements the following functions, which can be imported
individually.
decode_json¶
my $value = decode_json $bytes;
Decode JSON to Perl value and die if decoding fails.
encode_json¶
my $bytes = encode_json {i => 'X mojolicious'};
Encode Perl value to JSON.
false¶
my $false = false;
False value, used because Perl has no native equivalent.
from_json¶
my $value = from_json $chars;
Decode JSON text that is not "UTF-8" encoded to Perl value and die if
decoding fails.
my $bytes = j [1, 2, 3];
my $bytes = j {i => 'X mojolicious'};
my $value = j $bytes;
Encode Perl data structure (which may only be an array reference or hash
reference) or decode JSON, an "undef" return value indicates a bare
"null" or that decoding failed.
to_json¶
my $chars = to_json {i => 'X mojolicious'};
Encode Perl value to JSON text without "UTF-8" encoding it.
true¶
my $true = true;
True value, used because Perl has no native equivalent.
