Suggested XML-RPM format

Voor de beveiliging worden een aantal maatregelen genomen:

de XML-RPC interface gebeurd via HTTP (SSL beveiliging)
in de aanvraag wordt “KlantNr” gespecificeerd, dit is het debiteurennummer in de database
in de aanvraag wordt een “AuthNounce” code gestuurd, dit is een random getal van een bepaalde formaat/lengte
in de aanvraag wordt een “AuthKey” code gestuurd, dit is de AuthNounce code vercijfert met een vaste sleutel die bij beide partijen bekend is.
er wordt slecht 1 XML-RPC aanvraag per 3 seconden beantwoord (om Denial-of-Service attacks tegen te gaan)
bij een authenticatiefout wordt 30 seconden lang niet geantwoord (om brute-force key hacking pogingen tegen te gaan)

Example of PHP implementation

This is a working example of XML-RPC in PHP.
Found this on: http://nl2.php.net/xmlrpc

clienttest.php

<?php
function do_call($host, $port, $request) {
    $fp = fsockopen($host, $port, $errno, $errstr);
    $query =
      "POST /servertest.php HTTP/1.0\n".
      "User_Agent: My Egg Client\n".
      "Host: ".$host."\n".
      "Content-Type: text/xml\n".
      "Content-Length: ".strlen($request).
      "\n\n".
      $request."\n";

    if (!fputs($fp, $query, strlen($query))) {
        $errstr = "Write error";
        return 0;
    }

    $contents = '';
    while (!feof($fp)) {
        $contents .= fgets($fp);
    }

    fclose($fp);
    return $contents;
}

$host = 'www.networkconcepts.nl';
$port = 80;
$request = xmlrpc_encode_request('cycle', 'egg');
$response = do_call($host, $port, $request);
echo "\n\n<pre>\n$response\n</pre>\n\n"
?>

servertest.php

<?php
function lifecycle($method, $params) {
/* 
$method = 'cycle', $params = (array of) request parameter(s); $data is 
also passed from xmlrpc_server_call_method, if we had any data to pass.
*/
    switch($params[0]) {
        case 'egg':
            $reply = 'All eggs will be birds one day.';
        break;
        default:
            $reply = 'That must have been an otheregg';
    }
    return $reply;
}

$server = xmlrpc_server_create();

/* register the 'external' name and then the 'internal' name */
xmlrpc_server_register_method($server, "cycle", "lifecycle");

// no you don't need 'always on', and no $_POST doesn't work.
$request = $HTTP_RAW_POST_DATA; 

/*
the parameters here are 'server, xml-string and user data'.  
There's supposed to be an optional 'output options' array too, 
but I can't get it working :( hence header() call 
*/
$response = xmlrpc_server_call_method($server, $request, null);
header('Content-Type: text/xml');
print $response;

xmlrpc_server_destroy($server);
?>

The request sent

POST /servertest.php HTTP/1.0
User_Agent: My Egg Client
Host: www.networkconcepts.nl
Content-Type: text/xml
Content-Length: 185

<?xml version="1.0" encoding="iso-8859-1"?>
<methodCall>
<methodName>cycle</methodName>
<params>
 <param>
  <value>
   <string>egg</string>
  </value>
 </param>
</params>
</methodCall>

The response received

HTTP/1.1 200 OK
Date: Fri, 25 Jan 2008 22:28:46 GMT
Server: Apache/2.0.52 (CentOS)
X-Powered-By: PHP/4.3.9
