PHP-EWS - Subscription / PushNotification - complete example

Question

after two frustrating days I give up. I have one virtual maschine "admx" with Win2012R2 + Exchange 2013 (Trailversion) and one virtual maschine "webserver" with a IIS-Webserver+PHP.

Make a new Subscription - sub.php:

<?PHP
function __autoload($class_name)
{
    // Start from the base path and determine the location from the class name,
    $base_path = 'php-ews';
    $include_file = $base_path . '/' . str_replace('_', '/', $class_name) . '.php';
    //$include_file = str_replace('_', '/', $class_name) . '.php';

    return (file_exists($include_file) ? require_once $include_file : false);
}

$server = "admx";
$host = $server;
$username = "[email protected]";
$password = "secret123";
$version = "Exchange2013";

$url = "http://webserver/testexchange/log.php";
$keepAliveFrequency = 1;

$ews = new ExchangeWebServices($server, $username, $password, $version);
$subscribe_request = new EWSType_SubscribeType();
$pushSubscription = new EWSType_PushSubscriptionRequestType();
$pushSubscription->StatusFrequency = $keepAliveFrequency;
$pushSubscription->URL = $url;
$folderIDs = new EWSType_NonEmptyArrayOfBaseFolderIdsType();
$eventTypes = new EWSType_NonEmptyArrayOfNotificationEventTypesType();
$folderIDs->DistinguishedFolderId = new EWSType_DistinguishedFolderIdType();
$folderIDs->DistinguishedFolderId->Id = EWSType_DistinguishedFolderIdNameType::INBOX;
$eventTypes->EventType = "NewMailEvent";
$pushSubscription->FolderIds = $folderIDs;
$pushSubscription->EventTypes = $eventTypes;
$subscribe_request->PushSubscriptionRequest = $pushSubscription;
$response = $ews->Subscribe($subscribe_request);

var_dump($response);
?>

Output:

object(stdClass)#10 (1) { ["ResponseMessages"]=> object(stdClass)#11 (1) { ["SubscribeResponseMessage"]=> object(stdClass)#12 (4) { ["ResponseCode"]=> string(7) "NoError" ["ResponseClass"]=> string(7) "Success" ["SubscriptionId"]=> string(64) "EgBhZG14LnRlc3Rkb20ubG9jYWwQAAAA3keYE/U5Mkacz2FAg6DfHKdXyqelf9II" ["Watermark"]=> string(40) "AQAAAF57K7d1ihJLl9odwZ02gVahGgAAAAAAAAA=" } } } 

So, the subscription is successfully registered. Here is the listener - log.php

<?PHP
echo "<?xml version=\"1.0\" encoding=\"UTF-8\"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:ns1=\"http://schemas.microsoft.com/exchange/services/2006/messages\">
    <SOAP-ENV:Body>
        <ns1:SendNotificationResult>
            <ns1:SubscriptionStatus>OK</ns1:SubscriptionStatus>
        </ns1:SendNotificationResult>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>";

file_put_contents("C:\\exlog\\only_ok_".time().".txt", print_r($_REQUEST,1));
?>

Now I get every minute (because $keepAliveFrequency = 1;) a new respone / StatusCheck from the Exchange-Server. When I send a eMail to [email protected] I get a new notification immediately too (because "NewMailEvent" in Inbox). I acknowledge it with OK as XML, to keep-alive the subscription... So far so good.

But in the logfile (only_ok_1435488594.txt) is only...

Array()

Update log.php to get notification-information:

<?PHP
 class ewsService {
    public function SendNotification( $arg ) {
        file_put_contents("C:\\exlog\\logfile2_".time().".txt", print_r($arg,1));
        $result = new EWSType_SendNotificationResultType();
        $result->SubscriptionStatus = 'OK';
        //$result->SubscriptionStatus = 'Unsubscribe';
        return $result;
    }
}


$server = new SoapServer( 'php-ews/wsdl/NotificationService.wsdl', array(    'uri' => 'http://webserver/testexchange/log.php'));
$server->setObject( $service = new ewsService() );
$server->handle();
?>

And now the logfile as more informations as "array()":

stdClass Object
(
    [ResponseMessages] => stdClass Object
        (
            [SendNotificationResponseMessage] => stdClass Object
                (
                    [ResponseCode] => NoError
                    [ResponseClass] => Success
                    [Notification] => stdClass Object
                        (
                            [SubscriptionId] => EgBhZG14LnRlc3Rkb20ubG9jYWwQAAAAvfY+2ehqCEOXroWYNAsn+mD+ZBQYf9II
                            [PreviousWatermark] => AQAAAF57K7d1ihJLl9odwZ02gVZNGAAAAAAAAAA=
                            [MoreEvents] => 
                            [StatusEvent] => stdClass Object
                                (
                                    [Watermark] => AQAAAF57K7d1ihJLl9odwZ02gVZNGAAAAAAAAAA=
                                )

                        )

                )

        )
)

Problem: The Subscriptions gets after 3 more notifications lost. From the MSDN-documentation I know, the Exchangeserver retry 3-times the statusmessage to get a "OK" from the listener.

I has download the NotificationService.wsdl from GoogleSearch.

I have also add this, because without it I get a "bind error"

    <wsdl:port name="NotificationServicePort" binding="tns:NotificationServiceBinding">

    </wsdl:port>

I'm no Pro in SOAP... Whats going wrong here? Thank you Olli
