NAME

    MojoX::JSONRPC2::HTTP - Client for JSON RPC 2.0 over HTTP

VERSION

    This document describes MojoX::JSONRPC2::HTTP version v1.0.5

SYNOPSIS

        use MojoX::JSONRPC2::HTTP;
    
        $client = MojoX::JSONRPC2::HTTP->new;
    
        # setup
        $client
            ->url('http://example.com/endpoint')
            ->method('GET')
            ->type('application/json-rpc')
            ->headers({'X-Answer'=>42,…})
            ;
        # get Mojo::UserAgent to setup it (timeouts, etc.)
        $ua = $client->ua;
    
        # blocking notifications and calls
        ($failed, $result, $error) = $client->call('method', @params);
        ($failed, $result, $error) = $client->call_named('method', %params);
        $failed = $client->notify('method', @params);
        $failed = $client->notify_named('method', %params);
    
        # non-blocking calls
        $client->call('method', @params, \&cb);
        $client->call_named('method', %params, \&cb);
        sub cb {
            my ($failed, $result, $error) = @_;
        }
    
        # non-blocking notifications
        $client->notify('method', @params, \&cb_failed);
        $client->notify_named('method', %params, \&cb_failed);
        sub cb_failed {
            my ($failed) = @_;
        }

DESCRIPTION

    Provide HTTP transport for JSON RPC 2.0 using Mojo::UserAgent.

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

ATTRIBUTES

    All these methods return current value when called without params or
    set new value and return their object (to allow method chaining) when
    called with single param.

    url

      RPC endpoint url.

      This is only required parameter which must be set before doing RPC
      calls.

    method

      Default is 'POST', and only another supported value is 'GET'.

    type

      Default is 'application/json'.

    headers

      Default is empty HASHREF. Either modify it by reference or set it to
      your own HASHREF with any extra headers you need to send with RPC
      call.

    ua

      Mojo::UserAgent object used for sending HTTP requests - feel free to
      setup it or replace with your own object.

METHODS

    new( %attrs )

    new( \%attrs )

      You can set attributes listed above by providing their values when
      calling new() or later using individual attribute methods.

    call( 'method', @params )

    call( 'method', @params, \&cb )

    call_named( 'method', %params )

    call_named( 'method', %params, \&cb )

      Do blocking or non-blocking (when \&cb param provided) RPC calls,
      with either positional or named params. Blocking calls will return
      these values (non-blocking will call \&cb with same values as
      params):

          ($failed, $result, $error)

      In case of transport-level errors, when we fail to either send RPC
      request or receive correct reply from RPC server the $failed will
      contain error message, while $result and $error will be undefined.

      In case remote 'method' or RPC server itself will return error it
      will be available in $error as HASHREF with keys {code}, {message}
      and optionally {data}, while $failed and $result will be undefined.

      Otherwise value returned by remote 'method' will be in $result, while
      $failed and $error will be undefined.

    notify( 'method', @params )

    notify( 'method', @params, \&cb )

    notify_named( 'method', %params )

    notify_named( 'method', %params, \&cb )

      Do blocking or non-blocking (when \&cb param provided) RPC calls,
      with either positional or named params. Blocking calls will return
      this value (non-blocking will call \&cb with same value as param):

          $failed

      It will contain error message in case of transport-level error or
      will be undefined if RPC call was executes successfully.

LIMITATIONS

    Batch/Multicall feature

      Not supported because it is not implemented by JSON::RPC2::Client.
