MojoX::JSON::RPC::Client - JSON RPC client
use MojoX::JSON::RPC::Client; my $client = MojoX::JSON::RPC::Client->new; my $url = 'http://www.example.com/jsonrpc/API'; my $callobj = { id => 1, method => 'sum', params => [ 17, 25 ] }; my $res = $client->call($url, $callobj); if($res) { if ($res->is_error) { # RPC ERROR print 'Error : ', $res->error_message; } else { print $res->result; } } else { my $tx_res = $client->tx->res; # Mojo::Message::Response object print 'HTTP response '.$tx_res->code.' '.$tx_res->message; }
Non-blocking:
$client->call($url, $callobj, sub { # With callback my $res = pop; # ... process result ... Mojo::IOLoop->stop; }); Mojo::IOLoop->start;
Easy access:
my $proxy = $client->prepare($uri, ['sum', 'echo']); print $proxy->sum(10, 23);
A JSON-RPC client.
MojoX::JSON::RPC::Client implements the following attributes.
id
Id used for JSON-RPC requests. Used when no id is provided as request parameter.
ua
Mojo::UserAgent object.
json
Mojo::JSON object for encoding and decoding.
version
JSON-RPC version. Defaults to 2.0.
content_type
Content type. Defaults to application/json.
tx
Mojo::Transaction object of last request.
MojoX::JSON::RPC::Client inherits all methods from Mojo::Base and implements the following new ones.
new
Creates new MojoX::JSON::RPC::Client object.
my $client = MojoX::JSON::RPC::Client->new;
call
Execute JSON-RPC call. Returns MojoX::JSON::RPC::CLient::ReturnObject if RPC call is executed correctly.
my $client = MojoX::JSON::RPC::Client->new; my $url = 'http://www.example.com/jsonrpc/API'; my $callobj = { id => 1, method => 'sum', params => [ 17, 25 ] }; my $res = $client->call($url, $callobj); if($res) { if ($res->is_error) { # RPC error print 'Error : ', $res->error_message; } else { print $res->result; } } else { my $tx_res = $client->tx->res; # Mojo::Message::Response object print 'HTTP response '.$tx_res->code.' '.$tx_res->message; }
Make non-blocking call:
prepare
Prepares a proxy object that allows RPC methods to be called more easily.
my $proxy = $client->prepare($uri, ['sum', 'echo']); my $res = $proxy->sum(1, 2); print $proxy->echo("Echo this!");
Register services from multiple urls at once:
my $proxy = $client->prepare($uri1, 'sum', $uri2, [ 'echo', 'ping' ]); my $res = $proxy->sum(1, 2); print $proxy->echo("Echo this!"); my $ping_res = $proxy->ping;
MojoX::JSON::RPC::CLient::ReturnObject
This object is returned by call.
result
RPC result.
is_error
Returns a boolean indicating whether an error code has been set.
error_code
RPC error code.
error_message
RPC error message.
error_data
RPC error data.
