I am trying to create a website that retrieves data from a Web Service using the site API.
The 'nuSOAP' PHP library seems to be a perfect way to go about this and so I have been trying to run through a basic tutorial by Scott Nichol called 'Introduction to NuSOAP'.
Here is the code for server.php:
<?php
// Pull in the NuSOAP code
require_once('nusoap.php');
// Create the server instance
$server = new soap_server;
// Register the method to expose
$server->register('hello');
// Define the method as a PHP function
function hello($name) {
return 'Hello, ' . $name;
}
// Use the request to (try to) invoke the service
$HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : '';
$server->service($HTTP_RAW_POST_DATA);
?>
...and here is the code for the client.php:
<?php
// Pull in the NuSOAP code
require_once('nusoap.php');
// Create the client instance
$client = new soapclient('http://localhost/beehive/server.php');
// Call the SOAP method
$result = $client->call('hello', array('name' => 'John'));
// Display the result
print_r($result);
?>
I have 'XAMMP' installed and so when I call up client.php via the browser it should bring up a basic page that says 'Hello, John' but instead I get the following error message:
Fatal error: Uncaught SoapFault exception: [WSDL] SOAP-ERROR: Parsing WSDL: Couldn't load from '.../server.php' : Start tag expected, '<' not found in C:\xampp\htdocs\beehive\client.php:7 Stack trace: #0 C:\xampp\htdocs\beehive\client.php(7): SoapClient->SoapClient('http://...') #1 >{main} thrown in C:\xampp\htdocs\beehive\client.php on line 7
I figured I should be loading the client page rather than the server, but if I load server.php then I get the error message 'This service does not provide a Web description'.
I have followed the tutorial exactly and can't figure out why it's throwing this error; can anyone please help?
Thank you!
The error you receive makes perfect sense with your error description. The server isn't responding with the right format and therefor your client breaks.
The same error is discussed here: nusoap simple server
