CXXXVI. XML-RPC

Introduction

Ces fonctions servent à écrire des serveurs et clients XML-RPC. Vous trouverez plus d'informations sur XML-RPC sur le site , et plus de documenation sur cette extension et ses fonctions à .

Avertissement

Ce module est EXPERIMENTAL. Cela signifie que le comportement de ces fonctions, leurs noms et concrètement, TOUT ce qui est documenté ici peut changer dans un futur proche, SANS PREAVIS! Soyez-en conscient, et utilisez ce module à vos risques et périls.

Pré-requis

Ces fonctions sont disponibles dans le module PHP standard, qui est toujours accessible.

Installation

Le support de XML-RPC en PHP n'est pas activé par défaut. Vous avez besoin de l'activer grâce à l'option de compilation --with-xmlrpc[=DIR]. Cette extension est fournie avec PHP depuis la version 4.1.0.

Configuration à l'exécution

Le comportement de ces fonctions est affecté par la configuration dans le fichier php.ini.

The documentation lacks an example that shows how to send a fault in a response. Here is how to do it:



$args = array("faultCode" => $errcode, "faultString" => $errmsg);

$resp = xmlrpc_encode_request(NULL,$args);

//echo $resp;

On "datetime" values:



If you implement an XML-RPC server with these functions and a client calls a method on your server, sending a datetime as parameter (in ISO 8601 format, as specified at ), the PHP XML-RPC will pass your registered server method an object as parameter. That object, for example, looks like:

obj->type="datetime"

obj->scalar="20040420T13:32:40"

obj->timestamp=1082460760



If you do xmlrpc_get_type(obj), it will return "datetime", so presumably that function just returns the value of 'type'. 'scalar' seems to be the on-the-wire representation of the datetime (ISO 8601, exactly as received). 'timestamp' appears to be the ISO value in 'scalar' converted into a normal PHP timestamp (i.e. Unix time_t).



Note on 'scalar': Using a MySQL DB, we did something like  "select blah where start_time >= $obj->scalar ;". That actually worked and returned expected results, so MySQL appears to handle that ISO 8601 format correctly.

It took me a while to get a client together without external libraries.  This very basic client/server pair works on my home set-up - hopefully it will save the next xml-rpc virgin some grief.





/* clienttest.php */


<?php


function do_call($host, $port, $request) {


    


    $fp = fsockopen($host, $port, $errno, $errstr);


    $query = "POST /home/servertest.php HTTP/1.0\nUser_Agent: My Egg Client\nHost: ".$host."\nContent-Type: text/xml\nContent-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 = 'localhost';


$port = 80;


$request = xmlrpc_encode_request('cycle', 'egg');


$response = do_call($host, $port, $request);


/* do something with $response, e.g. print it */


?>





/* 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");





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





/* 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);

Just a quick addition to my previous xmlrpc_client class: since you cannot use remote methods containing capital letters or methods from subhandlers (like 'system.listMethods()'), I added a 'call(...)' method to the class. 



<?php

    // this method should be copy/pasted in the 

    // xmlrpc_client class



    function call($function)

    {

        $return = NULL;

        $argv = func_get_args();

        array_shift($argv); // remove function argument

        $this->__call($function, $argv, &$return);

        return $return;

    }



    // now, you can also do

    $result = $client->call('system.listMethods');

    $sum = client->call('add', '1', '2');

?>

I use the following code (requires the overload extension) to make developing clients easier:



<?php

include("utils/utils.php"); // from xmlrpc-epi utils



/*

Usage:

    $client = new xmlrpc_client("");

    print $client->echo('x')."\n";

    print $client->add(1, 3)."\n";



*/

class xmlrpc_client

{

    var $url;

    var $urlparts;



    function xmlrpc_client($url)

    {

        $this->url = $url;

        $this->urlparts = parse_url($this->url);

        foreach(array('scheme', 'host', 'user', 'pass', 'path',

                      'query', 'fragment')

                as $part) {

            if (!isset($this->urlparts[$part])) { 

                $this->urlparts[$part] = NULL;

                }

            }

    }



    function __call($function, $arguments, &$return)

    {

        $requestprms['host'] = $this->urlparts['host'];

        $requestprms['port'] = $this->urlparts['port'];

        $requestprms['uri'] = $this->urlparts['path'];

        $requestprms['method'] = $function;

        $requestprms['args'] = $arguments;

        $requestprms['debug'] = 0;

        $requestprms['timeout'] = 0;

        $requestprms['user'] = NULL;

        $requestprms['pass'] = NULL;

        $requestprms['secure'] = 0;



        $result = xu_rpc_http_concise($requestprms);

        if (is_array($result) && isset($result['faultCode'])) {

            print('Error in xmlrpc call \''.$function.'\''."\n");

            print('  code   : '.$result['faultCode']."\n");

            print('  message: '.$result['faultString']."\n");

            return false;

            }

        $return = $result;

        return true;

    }



}

overload('xmlrpc_client');

here's how to install it on windows (so it actually works):



- php.ini > enable "php_xmlrpc.dll" in extensions.

- php.ini > make sure "extension_dir" is set correctly to find the dll in your php installation dir /extensions.

- copy iconv.dll from your php install dir /dlls to a directory in your path (ex: c:/windows).



if you got some errors while launching apache prior to trying this I suggest you reboot your machine first... sounds weird I know, but remember... you're running Windowz.

Have fun

To install xml-rpc feature on Windows, you need to have "php_xmlrpc.dll" on your "/extensions" Folder.

And you need to enable it on "php.ini".



You need also library from  .

to make your code simply.



Look the examples at  .

Hope this saves somone some frustration:

As of php 4.3.1 and xmlrpc-epi-php-0.51 php would return a content type text/html instead of text/xml in its responses.  this is a bad thing.  Perl's XMLRPC::Lite for instance will not like you if you do this.  Happily the solution is simple:



header("Content-Type: text/xml");



Happy Hunting.

If anyone is interested in making XMLRPC requests directly from the client, I have been able to get xmlrpc to 

work with vcXMLRPC javascript backend.



After about 1 week of scanning the market, I found this solution to be the best on Javascript back end.  It uses the Microsoft.HTTP activeX control for IE, or HTTPRequest Object for Mozilla.



You include vc(Virtual Cowboys) vcXMLRPC.js file into your pages and make the rpc calls from with javascript to create the requests.



It works both ways.



Two Notes:



I have tested it on IE 6.02 and you need to change lines in ProcessRequest :

function to read:



  dom = this.getObject("XMLDOM",http.responseText);



and change the getObject function to use the latest ActiveX Control:



 MSXML2.XMLHTTP.3.0  (or 4.0)

 MSXML2.DOMDocument.3.0  (or 4.0)



The controls are found on MSDN in the Web Services -> XML area.



As another note, you DO NOT NEED the rpcproxy.cgi script to use this.  That is a proxy script to get around JS Security.  You can use PHP to build the proxy.  But, I was able to get the CGI working with GCC compiler on Solaris (change the -KPCI, depend and -x03 optimizer settings in the Makefile )

It's an easy client / server example - works quite good :-)

Note that you do need the iconv module installed to use the XML-RPC extension (see: )

There's a handy library by Keith Devens (version 2.2.1) at 








Here is a sample client. It remotely calls sample.sumAndDifference


with two parameters (3 and 5).


It returns:





sum => 8


difference => -2





<?php


include ("kd_xmlrpc.php");


// define("XMLRPC_DEBUG", 0);    // Set to 1 for handy debugging





$method = "sample.sumAndDifference";


$params = XMLRPC_prepare(array(3,5));





$site = "xmlrpc-c.sourceforge.net";


$location = "/api/sample.php";





list($success, $result) = XMLRPC_request( $site, $location, $method, $params );





// XMLRPC_debug_print();    // uncomment for debugging





foreach ( $result as $key => $value ) {


          echo(" $key => $value \n");


}

This extension does not handle the process of making making XML-RPC client requests via HTTP; it only prepares the XML-RPC request payload.



This differs from many other XML-RPC implementations but offers greater flexibility, allowing SSL connections, authentication headers and XML-RPC via other transports like SMTP.

For a really easy way to use this XML-RPC extension take a look at



XML-RPC Class Server ()



It automatically creates servers out of PHP classes. Creating clients is almost as easy, especially with the recent addition of the overload extension to PHP (see ).

nic at uklinux dot NOSPAM dot net

An alternative XML-RPC implementation is available at  - it's written in PHP so you can use it on servers for which you don't have the luxury of rebuilding PHP on.

"Latest releases" is a bit redundant, since this extension is bundled into PHP (as of 4.1.0).  You don't need to download anything from sourceforge to make this work.  Just compile PHP with the --with-xmlrpc flag.



The site  is useful, however, for documentation.
