NAME

Mojolicious::Plugin::JSONRPC2 - JSON-RPC 2.0 over HTTP

VERSION

This document describes Mojolicious::Plugin::JSONRPC2 version v2.0.4

SYNOPSIS

use JSON::RPC2::Server;

# in Mojolicious app
sub startup {
    my $app = shift;
    $app->plugin('JSONRPC2');

    my $server = JSON::RPC2::Server->new();

    $r->jsonrpc2('/rpc', $server);
    $r->jsonrpc2_get('/rpc', $server)->requires(
        headers => { $app->jsonrpc2_headers }
    );

DESCRIPTION

Mojolicious::Plugin::JSONRPC2 is a plugin that allow you to handle some routes in Mojolicious app using JSON-RPC 2.0 over HTTP protocol.

Implements this spec: http://www.simple-is-better.org/json-rpc/transport_http.html. The "pipelined Requests/Responses" is not supported yet.

INTERFACE

defaults

$app->defaults( 'jsonrpc2.timeout' => 300 );

Configure timeout for RPC requests in seconds (default value 5 minutes).

jsonrpc2

$app->routes->jsonrpc2( $path, $server );

Add handler for JSON-RPC 2.0 over HTTP protocol on $path (with format=>0) using POST method.

RPC functions registered with $server will be called only with their own parameters (provided with RPC request) - if they will need access to Mojolicious app you'll have to provide it manually (using global vars or closures).

jsonrpc2_get

$app->routes->jsonrpc2_get( $path, $server_safe_idempotent );

WARNING! In most cases you don't need it. In other cases usually you'll have to use different $server objects for POST and GET because using GET you can provide only safe and idempotent RPC functions (because of GET semantic, caching/proxies, etc.).

Add handler for JSON-RPC 2.0 over HTTP protocol on $path (with format=>0) using GET method.

RPC functions registered with $server_safe_idempotent will be called only with their own parameters (provided with RPC request) - if they will need access to Mojolicious app you'll have to provide it manually (using global vars or closures).

jsonrpc2_headers

$app->routes->requires(headers => { $app->jsonrpc2_headers });

You can use this condition to distinguish between JSON-RPC 2.0 and other request types on same $path - for example if you want to serve web page and RPC on same url you can do this:

my $r = $app->routes;
$r->jsonrpc2_get('/', $server)->requires(headers=>{$app->jsonrpc2_headers});
$r->get('/')->to('controller#action');

If you don't use this condition and plugin's handler will get request with wrong headers it will reply with 415 Unsupported Media Type.

OPTIONS

Mojolicious::Plugin::JSONRPC2 has no options.

METHODS
