get JSON data from RPC object php5.5 - php

Question

I have a RPC server class that accepts JSON data from an unspecified given 3rd party using cURL.
I can see the data hit my class, I can store a var_dump into a for what appears to be the server request, but the output looks like receiving webserver info with references to the inbound object.
But I do not see my JSON data 'foo:bar'
<?php
class jsonRPCServer {
public static function handle($object) {
if (
$_SERVER['REQUEST_METHOD'] != 'POST' ||
empty($_SERVER['CONTENT_TYPE']) ||
$_SERVER['CONTENT_TYPE'] != 'application/json'
) {
return false;
}
$request = json_decode(file_get_contents('php://input'),true);
$args=func_get_args();
ob_start();
var_dump($_SERVER);
$result2 = ob_get_clean();
$file = 'stripedump.txt';
$current = file_get_contents($file);
$current .= $result2;
file_put_contents($file, $current);
try {
if ($result = #call_user_func_array(array($object,$request['method']),$request['params'])) {
$response = array (
'id' => $request['id'],
'result' => $result,
'error' => NULL
);
} else {
$response = array (
'id' => $request['id'],
'result' => NULL,
'error' => 'unknown method or incorrect parameters'
);
}
} catch (Exception $e) {
$response = array (
'id' => $request['id'],
'result' => NULL,
'error' => $e->getMessage()
);
}
if (!empty($request['id'])) { // notifications don't want response
header('content-type: text/javascript');
echo json_encode($response);
}
return true;
}
}
?>
<?php
require_once 'example.php';
require_once 'jsonRPCServer.php';
$myExample = new example();
jsonRPCServer::handle($myExample)
or print 'no request';
echo '<b>Attempt to perform basic operations</b><br />'."\n";
try {
echo 'Your name is <i>'.$myExample->giveMeSomeData('name').'</i><br />'."\n";
$myExample->changeYourState('I am using this funnction from the local environement');
echo 'Your status request has been accepted<br />'."\n";
} catch (Exception $e) {
echo nl2br($e->getMessage()).'<br />'."\n";
}
var_dump($myExample);
echo '<br /><b>Attempt to store strategic data</b><br />'."\n";
try {
$myExample->writeSomething('bite me');
echo 'Strategic data succefully stored';
} catch (Exception $e) {
echo nl2br($e->getMessage());
}
?>

How do I access the JSON data from my inbound RPC object? (specifically 'foo:bar')

Answer 1

This works when used all by its self
<?php
$request = file_get_contents('php://input');
$args=func_get_args();
ob_start();
var_dump($request);
$result2 = ob_get_clean();
$file = 'stripedump.txt';
$current = file_get_contents($file);
$current .= $result2;
file_put_contents($file, $current);
?>
