NAME

JSON::RPC - Perl implementation of JSON-RPC 1.1 protocol

DESCRIPTION

JSON-RPC is a stateless and light-weight remote procedure call (RPC)
protocol for inter-networking applications over HTTP. It uses JSON
as the data format for of all facets of a remote procedure call,
including all application data carried in parameters.

quoted from http://json-rpc.org/wd/JSON-RPC-1-1-WD-20060807.html.

This module was in JSON package on CPAN before. Now its interfaces was completely changed.

The old modules - JSONRPC::Transport::HTTP and Apache::JSONRPC are deprecated. Please try to use JSON::RPC::Server and JSON::RPC::Client which support both JSON-RPC protocol version 1.1 and 1.0.

EXAMPLES

CGI version.

#--------------------------
# In your application class
package MyApp;

use base qw(JSON::RPC::Procedure); # Perl 5.6 or more than

sub echo : Public {    # new version style. called by clients
    # first argument is JSON::RPC::Server object.
    return $_[1];
}


sub sum : Public(a:num, b:num) { # sets value into object member a, b.
    my ($s, $obj) = @_;
    # return a scalar value or a hashref or an arryaref.
    return $obj->{a} + $obj->{b};
}

 
sub a_private_method : Private {
    # ... can't be called by client
}


sub sum_old_style {  # old version style. taken as Public
    my ($s, @arg) = @_;
   return $arg[0] + $arg[1];
}


#--------------------------
# In your triger script.
use JSON::RPC::Server::CGI;
use MyApp;

# simple
 JSON::RPC::Server::CGI->dispatch('MyApp')->handle();

# or 
JSON::RPC::Server::CGI->dispatch([qw/MyApp FooBar/])->handle();

# or INFO_PATH version
JSON::RPC::Server::CGI->dispatch({'/Test' => 'MyApp'})->handle();

#--------------------------
# Client
use JSON::RPC::Client;

my $client = new JSON::RPC::Client;

my $uri = 'http://www.example.com/jsonrpc/Test';
my $obj = {
   method  => 'sum', # or 'MyApp.sum'
   params  => [10, 20],
};

my $res = $client->call( $uri, $obj )

if($res){
   if ($res->is_error) {
       print "Error : ", $res->error_message;
   }
   else {
       print $res->result;
   }
}
else {
   print $client->status_line;
}

# or

$client->prepare($uri, ['sum', 'echo']);
print $client->sum(10, 23);
