How to I get JSON object data from inbound RPC?

[tunage]

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)

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

[iarp]

Try var_dump on $_GET or $_POST

[scootstah]

The JSON that you are inputting is not valid JSON, so json_decode() is probably failing. It should be:

 

curl -X POST -H "Content-Type: application/json" -d '{"foo":"bar"}' http://nyctelecomm.com/hooker/
