Parse error NuSOAP webservice with Codeigniter - codeigniter

Question

I'm using CodeIgniter with NuSOAP library for webservices and this is the error I get when accessing the Client controller:
wsdl error: XML error parsing WSDL from http://localhost/turismoadmin/index.php/Webservice/index/wsdl on line 77: Attribute without value
This is the server controller:
class Webservice extends CI_Controller {
function __construct(){
parent::__construct();
$this->load->library('soap_lib');
$server = new nusoap_server;
$server->configureWSDL('Agencia Turistica', 'urn:server');
$server->wsdl->schemaTargetNamespace = 'urn:server';
$server->register('addcontact',
array('nombre' => 'xsd:string', 'apellido' => 'xsd:string' , 'ciudad' => 'xsd:string'),
array('return' => 'xsd:string'));
$HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA: '';
$server->service($HTTP_RAW_POST_DATA);
}
function index()
{
if($this->uri->rsegment(3)=="wsdl"){
$_SERVER['QUERY_STRING']="wsdl";
}else{
$_SERVER['QUERY_STRING']="";
}
function addcontact($nombre, $apellido, $ciudad){
$this->modelo_turismo->addcontact($nombre, $apellido, $ciudad);
$resultado = $this->modelo_turismo->selectmax_contacto();
return (json_encode($resultado->fetch_all()));
}
}
}
and this is the Client controller:
class Client extends CI_controller {
function __construct() {
parent::__construct();
}
function index() {
$this->load->library('soap_lib');
$this->nusoap_client = new nusoap_client(site_url('Webservice/index/wsdl'), true);
$err = $this->nusoap_client->getError();
if ($err){
echo '<h2>Constructor error</h2><pre>' . $err . '</pre>';
}
$result1 = $this->nusoap_client->call('addcontact', array("marcos","de lafuente","hermosillo"));
echo($result1);
// Check for a fault
if ($this->nusoap_client->fault) {
echo '<h2>Fault</h2><pre>';
print_r($result1);
echo '</pre>';
} else {
// Check for errors
$err = $this->nusoap_client->getError();
if ($err) {
// Display the error
echo '<h2>Error</h2><pre>' . $err . '</pre>';
} else {
// Display the result
echo '<h2>Result</h2><pre>';
print_r($result1);
echo '</pre>';
}
}
}
}
I'm trying to do it based
ON THIS TOPIC (Thanks nana.chorage)
I also added this entry to my config/routes.php
$route['Webservice/wsdl']="Webservice/index/wsdl";
And for not to pass unnoticed, I can see my service when I enter this URL:
http://localhost/turismoadmin/index.php/Webservice/wsdl
I really dont know what I'm doing wrong, I have searched a lot around and I can't get rid of it!

Answer 1

Then nusoap client URL should be like this
$this->nusoap_client = new nusoap_client(site_url('Webservice/index?wsdl'), 'wsdl');
