Need help debugging a very basic PHP SOAP Hello world app
- by WarDoGG
I have been breaking my head at this, reading almost every article and tutorial there is on the web, but nothing doing.. i still cannot get my first web service application to work.
I would really appreciate it if anyone could debug this code for me and provide me with a good explanation as to what is wrong and why. This will help indeed ! Thanks !
I have pasted below the entire codes that i am using making it easier to debug. I'm using the PHP5 SOAP extension.
Here is my WSDL:
<?xml version="1.0" encoding="utf-8"?>
<wsdl:definitions name="testWebservice" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tm="http://microsoft.com/wsdl/mime/textMatching/" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:mime="http://schemas.xmlsoap.org/wsdl/mime/" xmlns:tns="http://tempuri.org/" xmlns:s1="http://microsoft.com/wsdl/types/" xmlns:s="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://schemas.xmlsoap.org/wsdl/soap12/" xmlns:http="http://schemas.xmlsoap.org/wsdl/http/" targetNamespace="http://tempuri.org/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/">

<soap:address location="http://127.0.0.1/nusoap/storytruck/index.php" />
</wsdl:port>
</wsdl:service>
</wsdl:definitions>
and here is the PHP Code i use to setup the server:
<?php
function getUser($user,$pass) {
return array('ID'=>1);
}
ini_set("soap.wsdl_cache_enabled", "0"); // disabling WSDL cache
$server = new SoapServer("http://127.0.0.1/mywsdl.wsdl");
$server->addFunction('getUser');
$server->handle();
?>
and the code for the client:
<?php
$client = new SoapClient("http://127.0.0.1/index.php?wsdl", array('exceptions' => 0));
try {
$result = $client->getUser("username","pass");
print_r($result);
}
catch (SoapFault $result) {
print_r($result);
}
?>
Here is the ERROR output i am getting on the browser :
