Alexa Webservices via SOAP

[mikotondria]

Hi 🙂.,.
Im just starting out trying to learn about using SOAP to access the Alexa Webservices, and have come to a halt..
I got the latest copy of nusoap.php and have put it into my working folder with all the classes, and am trying to call the 'UrlInfo' procedure using the below code:

<?php

// include class
include("nusoap.php");

// create a instance of the SOAP client object
// remember that this script is the client,
// accessing the web service provided by Amazon.com
$soapclient = new
soapclient("http://aws-beta.amazon.com/AWSAlexa/AWSAlexa.wsdl",
true);

// uncomment the next line to see debug messages
 $soapclient->debug_flag = 1;

// create a proxy so that WSDL methods can be accessed directly
$proxy = $soapclient->getProxy();

// set up an array containing input parameters to be
// passed to the remote procedure
$params = array(
		    'SubscriptionId' => '1405M88PWV52RDDEK***',
		    'ResponseGroup'  => 'Rank',
		    'Url'        => 'www.anywhere.com'
);


// invoke the method
$result = $proxy->UrlInfo($params);

// print the results of the search
print_r($result);
?>

The above page just gives no output..
Is there anything else I need to do to get this working ? The Subscription Id is my own; anybody ?

I added information and debugging code (from here) to your code:

include 'nusoap.php'; 
$soapclient = new soapclient('http://aws-beta.amazon.com/AWSAlexa/AWSAlexa.wsdl',  true); 
$err = $soapclient->getError();

if ($err) {
    echo '<p><b>Constructor error: ' . $err . '</b></p>';
}

$soapclient->debug_flag = 1; 
$proxy = $soapclient->getProxy(); 
$params = array('SubscriptionId' => '177NAF7BV5W4********', 
                'ResponseGroup'  => 'Rank', 
                'Url'            => 'www.amazon.com'); 
$result = $proxy->UrlInfo($params); 

if ($proxy->fault) {
    echo '<p><b>Fault: ';
    print_r($result);
    echo '</b></p>';
} else {
    $err = $proxy->getError();
    if ($err) {
        echo '<p><b>Error: ' . $err . '</b></p>';
    } else {
        print_r($result);
    }

}

echo '<h2>Request</h2>';
echo '<pre>' . htmlspecialchars($soapclient->request, ENT_QUOTES) . '</pre>';
echo '<h2>Response</h2>';
echo '<pre>' . htmlspecialchars($soapclient->response, ENT_QUOTES) . '</pre>';
echo '<h2>Debug</h2>';
echo '<pre>' . htmlspecialchars($soapclient->debug_str, ENT_QUOTES) . '</pre>';

and this is what I get (so far):

Error: HTTP Error: no data present after HTTP headers

Request

Response

2004-12-23 16:18:38.472522 soapclient: instantiating wsdl class with doc: http://aws-beta.amazon.com/AWSAlexa/AWSAlexa.wsdl

// and so on (c. 1000 lines)

hth - I'll probably do some more with it tomorrow.
