The curlRequest method in HttpJsonRpcConnectorAbstract cooks itself sending data by CURL. Just send named array as $data parametr to curlRequest.
There are public nodes in HTTP connectors
There are public nodes in WS connectors
There are availible methods
Example of using
<?php
use GrapheneNodeClient\Connectors\Http\WhalesharesHttpJsonRpcConnector;
use GrapheneNodeClient\Commands\CommandQueryData;
use GrapheneNodeClient\Commands\Single\GetBlockCommand;
$connector = new WhalesharesHttpJsonRpcConnector();
$block_id = 13;
$commandQuery = new CommandQueryData();
$commandQuery->setParamByKey('0', $block_id);
$command = new Commands($connector );
$command = $command->get_block();
$answer = $command->execute($commandQuery);
//OR
$command = new GetBlockCommand($connector);
$answer = $command->execute(
$commandQuery
);
//answer example
