NAME

Dancer2::Plugin::RPC - Namespace for XMLRPC, JSONRPC2 and RESTRPC plugins

DESCRIPTION

This module contains plugins for Dancer2: Dancer2::Plugin::RPC::XML, Dancer2::Plugin::RPC::JSON and Dancer2::Plugin::RPC::REST.

Dancer2::Plugin::RPC::XML

This plugin exposes the new keyword xmlrpc that is followed by 2 arguments: the endpoint and the arguments to configure the xmlrpc-calls at this endpoint.

Dancer2::Plugin::RPC::JSON

This plugin exposes the new keyword jsonrpc that is followed by 2 arguments: the endpoint and the arguments to configure the jsonrpc-calls at this endpoint.

Dancer2::Plugin::RPC::REST

This plugin exposes the new keyword restrpc that is followed by 2 arguments: the endpoint and the arguments to configure the restrpc-calls at this endpoint.

General arguments to xmlrpc/jsonrpc/restrpc

The dispatch table is build by endpoint.

publish => <config|pod|$coderef>

publish => config

The dispatch table is build from the YAML-config:

plugins:
    'RPC::XML':
        '/endpoint1':
            'Module::Name1':
                method1: sub1
                method2: sub2
            'Module::Name2':
                method3: sub3
        '/endpoint2':
            'Module::Name3':
                method4: sub4

The arguments argument should be empty for this publishing type.

publish => pod

The dispatch table is build by parsing the POD for =for xmlrpc, =for jsonrpc or =for restrpc.

=for xmlrpc <method_name> <sub_name>

The arguments argument must be an Arrayref with module names. The POD-directive must be in the same file as the code!

publish => $coderef

With this publishing type, you will need to build your own dispatch table and return it.

use Dancer2::RPCPlugin::DispatchItem;
return {
    method1 => dispatch_item(
        package => 'Module::Name1',
        code => Module::Name1->can('sub1'),
    ),
    method2 => dispatch_item(
        package => 'Module::Name1',
        code    => Module::Name1->can('sub2'),
    ),
    method3 => dispatch_item(
        pacakage => 'Module::Name2',
        code     => Module::Name2->can('sub3'),
    ),
};

arguments => $list

This argumument is needed for publishing type pod and must be a list of module names that contain the pod (and code).

callback => $coderef

The callback argument may contain a $coderef that does additional checks and should return a Dancer2::RPCPlugin::CallbackResult object.

$callback->($request, $method_name, @method_args);

Returns for success: callback_success()

Returns for failure: callback_fail(error_code => $code, error_message => $msg)

This is useful for ACL checking.

code_wrapper => $coderef

The code_wrapper argument can be used to wrap the code (from the dispatch table).

my $wrapper = sub {
    my $code   = shift;
    my $pkg    = shift;
    my $method = shift;
    my $instance = $pkg->new();
    $instance->$code(@_);
};
