Web Services

[neo-truth]

Greetings, all:

 

I have a website hosted with IX Webhosting.  I'm attempting to use the website to communicate with a program I have on the application server here at my office.  I have tried using both Keith Deven's XML-RPC Library for PHP as well as nuSOAP and get similar results with both.  I can't seem to open a connection to the local server.  I can plug in the IP address into a browser and it will open up the Axis service page as well as the WSDL for our program, but when I use the same URLs in the PHP scripts, it times out every time.  I've also tried just using a simple fsockopen() script to rule out any issues with the code packages, but it doesn't work either.  When I plug in the wrong port number (e.g. https instead of web services) I get a 400 bad request response, but with the right port number, it just times out.

 

Is it possible my web host is somehow blocking this sort of connection?  Could it be a local issue with the firewall or server setup -- if so, why can I open the URL in a browser?

 

I'm really at a wall here.  I've exhausted my limited knowledge.  I'm not a "professional" developer, but I need to get this working for our business.  Any help would be greatly appreciated.

well if you run a business maybe you should ask this question in the right location cause you have no php question to be answered

Well, here's the long story.  I have been playing around with HTML and the like for the past 10-12 years.  I made websites for myself and occasionally for friends or family.  I have no real formal education in programming aside from one semester in C++ about 4 years ago (I made an A if that counts for anything  ).  I've played around with PHP casually off and on during that time.

 

My step-father owns several businesses and I've made websites for two of them.  I don't run any businesses, I'm just the guy that got suckered into making websites and doing "computer stuff" for my step-father.

 

The site in question is bristolautoauction.net.  It's coded in PHP/MySQL and held together with duct tape and super glue.  Everything was going fine until they installed a new program and computer system at the auction.  The program-maker installed application and database servers that handle the program at the auction.  Now they want to use web services to keep the servers and website in sync.  So, I have to try and make that work.

 

I've tried numerous different approaches and haven't made any headway.  I really don't know how to proceed.  I decided I would post here, since I'm using PHP as a web services client, and ask for some form of help or guidance.

 

Here is the nuSOAP PHP code I am trying to use (I've replaced the actual IP and port with "ip:port"):

<?php
// Pull in the NuSOAP code
require_once('../../nusoap/lib/nusoap.php');
// Create the client instance
$client = new nusoap_client('http://ip:port/VeroWebService/services/VeroWebService');

// Check for an error
$err = $client->getError();
if ($err) {
    // Display the error
    echo '<p><b>Constructor error: ' . $err . '</b></p>';
    // At this point, you know the call that follows will fail
}
// Call the SOAP method
$result = $client->call(
'getVehiclesForPresale',	// method name
array('SaleId' => '4'),		// input parameters
'urn:VehicleModel',			// namespace
'VasWebService'				// SOAPAction
);


// Check for a fault
if ($client->fault) {
    echo '<p><b>Fault: ';
    print_r($result);
    echo '</b></p>';
} else {
    // Check for errors
    $err = $client->getError();
    if ($err) {
        // Display the error
        echo '<p><b>Error: ' . $err . '</b></p>';
    } else {
        // Display the result
        print_r($result);
    }

// Display the request and response
echo '<h2>Request</h2>';
echo '<pre>' . htmlspecialchars($client->request, ENT_QUOTES) . '</pre>';
echo '<h2>Response</h2>';
echo '<pre>' . htmlspecialchars($client->response, ENT_QUOTES) . '</pre>';
// Display the debug messages
echo '<h2>Debug</h2>';
echo '<pre>' . htmlspecialchars($client->debug_str, ENT_QUOTES) . '</pre>';

}

?>

 

Basically copied and pasted from the documentation.

 

And here is the Debug information that nuSOAP spits out:

Every which way I've tried it, it times out.  When I've tried the https port, that doesn't point to the web service, a request and response are actually sent, which doesn't appear to happen with the correct port number.

 

If there's no issue with the PHP code, perhaps someone can suggest some other means of figuring this thing out.  I really don't know what the problem could be.

Firewall?

[neo-truth]

The port is open on the firewall.  I can use the ip:port in a browser and it will open, it just doesn't want to work with PHP.  Maybe I'm overlooking something?
