PHP with XMLRPC and/or SOAP hangs

PHP
1

Hello. I’m trying to access a webservice which supports both XMLRPC and SOAP on https://xxx.xxx.xxx.xxx:8080/, but it always hangs at curl_exec (i think) saying “Error, code 8: CURL error: couldn’t connect to host”.

I’m using PHP 5.2.1 with libcurl/7.15.3 OpenSSL/0.9.7a on a hosted web solution.

I’ve tried both NuSOAP: http://dietrich.ganx4.com/nusoap/
and PHP XMLRPC: http://phpxmlrpc.sourceforge.net/

All examples included in these libraries seem to work, but when I try on my own with:


require_once('nusoaplib/nusoap.php');
$proxyhost = isset($_POST['proxyhost']) ? $_POST['proxyhost'] : '';
$proxyport = isset($_POST['proxyport']) ? $_POST['proxyport'] : '';
$proxyusername = isset($_POST['proxyusername']) ? $_POST['proxyusername'] : '';
$proxypassword = isset($_POST['proxypassword']) ? $_POST['proxypassword'] : '';
$client = new soapclient('https://xxx.xxx.xxx.xxx:8080/', false,
						$proxyhost, $proxyport, $proxyusername, $proxypassword);
$err = $client->getError();
if ($err) {
	echo '<h2>Constructor error</h2><pre>' . $err . '</pre>';
}
$result = $client->call('find_products', array('username','password',userid,'boarding'));
if ($client->fault) {
	echo '<h2>Fault</h2><pre>'; print_r($result); echo '</pre>';
} else {
	$err = $client->getError();
	if ($err) {
		echo '<h2>Error</h2><pre>' . $err . '</pre>';
	} else {
		echo '<h2>Result</h2><pre>'; print_r($result); echo '</pre>';
	}
}
echo '<h2>Request</h2><pre>' . htmlspecialchars($client->request, ENT_QUOTES) . '</pre>';
echo '<h2>Response</h2><pre>' . htmlspecialchars($client->response, ENT_QUOTES) . '</pre>';
echo '<h2>Debug</h2><pre>' . htmlspecialchars($client->debug_str, ENT_QUOTES) . '</pre>';

i get the following response:

it seems like the webservice dosn’t exists to PHP? But the webservice provider claims the service is up and running at https://xxx.xxx.xxx.xxx:8080/ (which actually gives a response when entered directly in the browser, it’s just PHP/CURL who don’t seem to find it?)

Any idea what the problem could be? And what does the proxy parameters mean? Is this anything I need to fill out?

Any help greatly appreciated!:slight_smile:

do the contents appear when you try to file_get_contents(“https://xxx.xxx.xxx.xxx:8080/”) on the site?

If not, then it may be that the site doesn’t allow web programs to view it.

3

Hm, hard to tell:

Warning: file_get_contents() [function.file-get-contents]: URL file-access is disabled in the server configuration…

4

Ah, you need to enable ‘allow_url_fopen’ in php.ini

5

Yes, but I can’t since I’m on a shared host… But the https request itself in NuSOAP goes via CURL as far as I can tell? So enabling allow_url_fopen wouldn’t solve the actual problem?

6

It seems like the connection is blocked by server’s firewall; which is likely on a shared host?

7

That seems possible. I’ll contact my hosting provider to confirm this.

8

Host confirmed that connection was blocked in firewall, and opened 8080 which solved the problem :slight_smile:

For XML-RPC you can use the xmlrpc library from the crVCL Framework, it is easy to use and work also fast for a high number of requests.
