Dancer::Plugin::RPC - Configure endpoints for XMLRPC and JSONRPC procedures


This module contains two plugins for Dancer: Dancer::Plugin::RPC::XMLRPC and Dancer::Plugin::RPC::JSONRPC. They are plugins rather than Plack::Middleware.


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.


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.

General arguments to xmlrpc/jsonrpc

The dispatch table is build by endpoint.

publish => <config|pod|$coderef>

publish => config

The dispatch table is build from the YAML-config:

                    method1: sub1
                    method2: sub2
                    method3: sub3
                    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 or =for jsonrpc.

    =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 Dancer::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 Dancer::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();
