LINK DEMO:
ISTRUZIONI:
- Estrarre il pacchetto (htdocs del vostro webserver)
- configurare il file config/config.php
define('DB_HOST', '');//esempio localhost
define('DB_USER', '');//esempio wscrud
define('DB_NAME', '');//esempio wscrud
define('DB_PWD', '');//esempio wscrud
define('WSDL', '');//esempio http://maxb.net/scripts/wscrud/?wsdl
- creare il database e importare il dump presente in config/db.sql
LIBRERIE DA SCARICARE A PARTE:
Una volta scaricate ed estratte le librerie dovranno essere inserite nella directory libs come nell’immagine.
Non sono un grande esperto di servizi. Mi è capitato di farne e di usufruirne.
Questa volta ho deciso di estrapolare dall’ultimo lavoro una sorta di scheletro.
Il servizio spiegato:
Inclusioni di librerie:
require_once(dirname(__FILE__) . '/libs/adodb_lite/adodb.inc.php');
require_once(dirname(__FILE__) . '/libs/nusoap-0.7.3/lib/nusoap.php');
require_once(dirname(__FILE__) . '/config/config.php');
require_once(dirname(__FILE__) . '/includes/exception.php');
require_once(dirname(__FILE__) . '/includes/application.php');
require_once(dirname(__FILE__) . '/includes/conn.php');
require_once(dirname(__FILE__) . '/includes/db.php');
Inizializzazione server (vedere il config per capire le costanti):
$server = new nusoap_server();
$server->configureWSDL(APP_NAME_SPACE,APP_TARGET_NAME_SPACE);
$server->wsdl->schemaTargetNamespace = APP_TARGET_NAME_SPACE;
Tipi complessi registrati:
$server->wsdl->addComplexType(
'record',
'complexType',
'struct',
'all',
'',
array(
'id' => array('name'=>'id','type'=>'xsd:int'),
'text' => array('name'=>'text','type'=>'xsd:string'),
)
);
$server->wsdl->addComplexType(
'array_of_record',
'complexType',
'array',
'',
'SOAP-ENC:Array',
array(),
array(array('ref'=>'SOAP-ENC:arrayType','wsdl:arrayType'=>'tns:record[]')),
'tns:record'
);
I metodi esposti:
$server->register(
'put_record',
array('text'=>'xsd:string'),
array('id'=>'xsd:int'),
APP_URN,
APP_URN . '#put_record',
'rpc',
'encoded',
''
);
function put_record($text){
try{
$app = new MyApplication();
return $app->dao->put_record($text);
}catch(Exception $e){
return new soap_fault($e->getCode(), 'server', $e->getMessage());
}
}
$server->register(
'search_record',
array(
'id'=>'xsd:int',
'text'=>'xsd:string',
),
array('return'=>'tns:array_of_record'),
APP_URN,
APP_URN . '#search_record',
'rpc',
'encoded',
''
);
function search_record($id, $text){
try{
$app = new MyApplication();
return $app->dao->search_record($id, $text);
}catch(Exception $e){
return new soap_fault($e->getCode(), 'server', $e->getMessage());
}
}
$server->register(
'get_record',
array('id'=>'xsd:int'),
array('return'=>'tns:record'),
APP_URN,
APP_URN . '#get_record',
'rpc',
'encoded',
''
);
function get_record($id){
try{
$app = new MyApplication();
return $app->dao->get_record($id);
}catch(Exception $e){
return new soap_fault($e->getCode(), 'server', $e->getMessage());
}
}
$server->register(
'delete_record',
array('id'=>'xsd:int'),
array('return'=>'xsd:boolean'),
APP_URN,
APP_URN . '#delete_record',
'rpc',
'encoded',
''
);
function delete_record($id){
try{
$app = new MyApplication();
return $app->dao->delete_record($id);
}catch(Exception $e){
return new soap_fault($e->getCode(), 'server', $e->getMessage());
}
}
$server->register(
'update_record',
array('id'=>'xsd:int', 'text' => 'xsd:string'),
array('return'=>'xsd:boolean'),
APP_URN,
APP_URN . '#update_record',
'rpc',
'encoded',
''
);
function update_record($id, $text){
try{
$app = new MyApplication();
return $app->dao->update_record($id, $text);
}catch(Exception $e){
return new soap_fault($e->getCode(), 'server', $e->getMessage());
}
}
L’output del “server”:
$HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : file_get_contents("php://input");
$server->service($HTTP_RAW_POST_DATA);
Attenzione a quel file_get_contents(“php://input”);
Ho sclerato parecchio per far girare questo servizio sul mio hosting.
IL CLIENT
L’esempio del client VERAMENTE basico senza librerie senza divisioni.
GREZZO. Anche l’html. Giusto il form e il meta per la codifica di invio dei dati.
require_once(dirname(__FILE__) . '/../config/config.php');
error_reporting(E_ALL);
function get_client(){
require_once(dirname(__FILE__) . '/../libs/nusoap-0.7.3/lib/nusoap.php');
$url = WSDL;
$client = new nusoap_client( $url, true );
return $client;
}
$client = get_client();
$args = array();
$records = $client->call( 'search_record', $args );
if(isset($_POST['save'])){
$_POST['text'] = stripslashes($_POST['text']);
$client = get_client();
if($_POST['id'] == 0){
$args = array( 'text' => $_POST['text']);
$result = $client->call( 'put_record', $args );
}else{
$args = array( 'id' => $_POST['id'], 'text' => $_POST['text']);
$result = $client->call( 'update_record', $args );
}
header('Location:?do=index');
}
$do = isset($_GET['do']) ? $_GET['do'] : false;
$data = array('id' => 0, 'text' => '');
switch($do){
case 'edit':
$client = get_client();
$args = array( 'id' => $_GET['id']);
$data = $client->call( 'get_record', $args );
break;
case 'delete':
$client = get_client();
$args = array( 'id' => $_GET['id']);
$result = $client->call( 'delete_record', $args );
header('Location:?do=index');
break;
}
<meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
<form method="post" action="#">
<p><textarea name="text" id="text"><?php echo $data['text']?></textarea></p>

All’interno della directory client troverete due client nativi (estensione soap del php5) : client2.php e client3.php.
Su questo hosting non girano.
Provateli se volete. client3.php usa il metodo “ufficiale” per chiamare i metodi remoti. NON FUNZIONA!
