CLVII. XML-RPC 函数
默认情况下在 PHP 中是不能使用 XML-RPC 支持的。你需要使用
--with-xmlrpc[=DIR]
配置选项编译 PHP 才能够使用 XML-RPC 支持。从 PHP 4.1.0 开始附带了此扩展。
这些函数的行为受 php.ini 的影响。
表格 1. XML-RPC 配置选项 名称 | 默认值 | 作用范围 | 更新日志 |
---|
xmlrpc_errors | "0" | PHP_INI_SYSTEM | 从 PHP 4.1.0 起开始存在 | xmlrpc_error_number | "0" | PHP_INI_ALL | 从 PHP 4.1.0 起开始存在 |
有关 PHP_INI_* 常量进一步的细节与定义参见 附录 G。

for others attempting the same thing, here is what a function would look like if you wanted to send a base64 encoded file from a client and then save it onto the server. the other code necessary to call this function via an RPC is available in other comments so i won't repeat it.
parameters:
1 - name of file
2 - base64 encoded data of file
note the use of $file_data->scalar
<?
function sendFile($method_name, $params, $user_data) {
$file = "/somedir/" . $params[0];
$file_data = $params[1];
$fh = @fopen($file, "wb");
if ($fh) {
if (@fwrite($fh, $file_data->scalar)) {
$msg = "success msg";
} else {
$msg = "couldn't write to file";
}
fclose($fh);
return $msg;
} else {
return "couldn't open file";
}
}
?>

I couldn't make the 'xmlrpc_errors' php.ini setting do anything
noticeable (PHP 4.3.11), so I used the following code to report errors
from my XMLRPC server. Hope it's helpful for someone.
<?php
function return_xmlrpc_error($errno,$errstr,$errfile=NULL,$errline=NULL
,$errcontext=NULL){
global $xmlrpc_server;
if(!$xmlrpc_server)die("Error: $errstr in '$errfile', line '$errline'");
header("Content-type: text/xml; charset=UTF-8");
print(xmlrpc_encode(array(
'faultCode'=>$errno
,'faultString'=>"Remote XMLRPC Error from
".$_SERVER['HTTP_HOST'].": $errstr in at $errfile:$errline"
)));
die();
}
set_error_handler('return_xmlrpc_error');
?>
In my server function, I just trigger_error("message",E_USER_ERROR)]
if something can't be completed.
Then on the client side,
<?php
$data =& xmlrpc_decode($response['body']);
if(xmlrpc_is_fault($data)){
trigger_error($data['faultString'],E_USER_ERROR);
}
?>

To connect to a python xmlrpc server I use:
function do_call($host, $port, $request) {
$url = "http://$host:$port/";
$header[] = "Content-type: text/xml";
$header[] = "Content-length: ".strlen($request);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_POSTFIELDS, $request);
$data = curl_exec($ch);
if (curl_errno($ch)) {
print curl_error($ch);
} else {
curl_close($ch);
return $data;
}
}
$request = xmlrpc_encode_request('add', array(3, 4));
$response = do_call($host, $port, $request);

The PHP XML-RPC project at SourceForge makes life a hell of a lot easier. However, the project uses some function names which are identical to thoses provided by the XML-RPC extention.
If you are on a server with XML-RPC extension compiled in but wish to use the PHP based version then you will have to rename some of the functions.
I notice that sourceforce says there is activity on the project in 2005 but the last release was January 12, 2003.
I recommend that you use this not so friendly PHP extention if available. However this sourceforce project is still a good idea if you don't control which extenions are be available on the server.

An easier alternative to the built-in XML-RPC function is available at:
http://phpxmlrpc.sourceforge.net/
PHP XML-RPC is written purely in PHP, so there is no need to recompile to use the experiment XML-RPC extension. PHP XML-RPC is also definitely easier to use, especially if you are creating a server. Documentation is available at the above link.

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 http://www.xmlrpc.com/spec), 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("http://localhost:7080");
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

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 )

There's a handy library by Keith Devens (version 2.2.1) at
http://www.keithdevens.com/software/xmlrpc/
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.

An alternative XML-RPC implementation is available at http://xmlrpc.usefulinc.com - 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 http://xmlrpc-epi.sourceforge.net/ is useful, however, for documentation.
