NAME
JSON::Any - (DEPRECATED) Wrapper Class for the various JSON classes
VERSION
version 1.39
SYNOPSIS
use JSON::Any;
my $j = JSON::Any->new;
my $json = $j->objToJson({foo=>'bar', baz=>'quux'});
my $obj = $j->jsonToObj($json);
DESCRIPTION
This module tries to provide a coherent API to bring together the various JSON modules
currently on CPAN. This module will allow you to code to any JSON API and have it work
regardless of which JSON module is actually installed.
use JSON::Any;
my $j = JSON::Any->new;
$json = $j->objToJson({foo=>'bar', baz=>'quux'});
$obj = $j->jsonToObj($json);
or
$json = $j->encode({foo=>'bar', baz=>'quux'});
$obj = $j->decode($json);
or
$json = $j->Dump({foo=>'bar', baz=>'quux'});
$obj = $j->Load($json);
or
$json = $j->to_json({foo=>'bar', baz=>'quux'});
$obj = $j->from_json($json);
or without creating an object:
$json = JSON::Any->objToJson({foo=>'bar', baz=>'quux'});
$obj = JSON::Any->jsonToObj($json);
On load, JSON::Any will find a valid JSON module in your @INC by looking for them in this
order:
Cpanel::JSON::XS
JSON::XS
JSON::PP
JSON
JSON::DWIW
And loading the first one it finds.
You may change the order by specifying it on the "use JSON::Any" line:
use JSON::Any qw(DWIW XS CPANEL JSON PP);
Specifying an order that is missing modules will prevent those module from being used:
use JSON::Any qw(CPANEL PP); # same as JSON::MaybeXS
This will check in that order, and will never attempt to load JSON::XS, "JSON" in JSON.pm,
or JSON::DWIW. This can also be set via the $ENV{JSON_ANY_ORDER} environment variable.
JSON::Syck has been deprecated by its author, but in the attempt to still stay relevant as
a "Compatibility Layer" JSON::Any still supports it. This support however has been made
optional starting with JSON::Any 1.19. In deference to a bug request starting with JSON.pm
1.20, JSON::Syck and other deprecated modules will still be installed, but only as a last
resort and will now include a warning.
use JSON::Any qw(Syck XS JSON);
or
$ENV{JSON_ANY_ORDER} = 'Syck XS JSON';
At install time, JSON::Any will attempt to install JSON::PP as a reasonable fallback if
you do not appear have any backends installed on your system.
WARNING: If you call JSON::Any with an empty list
use JSON::Any ();
It will skip the JSON package detection routines and will die loudly that it couldn't find
a package.
DEPRECATION NOTICE
The original need for JSON::Any has been solved (quite some time ago actually). If you're
producing new code it is recommended to use JSON::MaybeXS which will optionally use
Cpanel::JSON::XS for speed purposes.
JSON::Any will continue to be maintained for compatibility with existing code, but for new
code you should strongly consider using JSON::MaybeXS instead.
WARNING
JSON::XS 3.0 or higher has a conflict with any version of JSON.pm less than 2.90 when you
use JSON.pm's "-support_by_pp" option, which JSON::Any enables by default.
This situation should only come up with JSON::Any if you have JSON.pm 2.61 or lower and
JSON::XS 3.0 or higher installed, and you use JSON.pm via "use JSON::Any qw(JSON);" or the
"JSON_ANY_ORDER" environment variable.
If you run into an issue where you're getting recursive inheritance errors in a
Types::Serialiser package, please try upgrading JSON.pm to 2.90 or higher.
METHODS
"new"
Will take any of the parameters for the underlying system and pass them through. However
these values don't map between JSON modules, so, from a portability standpoint this is
really only helpful for those parameters that happen to have the same name.
The one parameter that is universally supported (to the extent that is supported by the
underlying JSON modules) is "utf8". When this parameter is enabled all resulting JSON will
be marked as unicode, and all unicode strings in the input data structure will be
preserved as such.
Also note that the "allow_blessed" parameter is recognised by all the modules that throw
exceptions when a blessed reference is given them meaning that setting it to true works
for all modules. Of course, that means that you cannot set it to false intentionally in
order to always get such exceptions.
The actual output will vary, for example JSON will encode and decode unicode chars (the
resulting JSON is not unicode) whereas JSON::XS will emit unicode JSON.
"handlerType"
Takes no arguments, returns a string indicating which JSON Module is in use.
"handler"
Takes no arguments, if called on an object returns the internal JSON::* object in use.
Otherwise returns the JSON::* package we are using for class methods.
"true"
Takes no arguments, returns the special value that the internal JSON object uses to map to
a JSON "true" boolean.
"false"
Takes no arguments, returns the special value that the internal JSON object uses to map to
a JSON "false" boolean.
"objToJson"
Takes a single argument, a hashref to be converted into JSON. It returns the JSON text in
a scalar.
"to_json"
"Dump"
"encode"
Aliases for "objToJson", can be used interchangeably, regardless of the underlying JSON
module.
"jsonToObj"
Takes a single argument, a string of JSON text to be converted back into a hashref.
"from_json"
"Load"
"decode"
Aliases for "jsonToObj", can be used interchangeably, regardless of the underlying JSON
module.
ACKNOWLEDGEMENTS
This module came about after discussions on irc.perl.org about the fact that there were
now six separate JSON perl modules with different interfaces.
In the spirit of Class::Any, JSON::Any was created with the considerable help of Matt
'mst' Trout.
Simon Wistow graciously supplied a patch for backwards compatibility with JSON::XS
versions previous to 2.01
