Ich versuche, GCM zu verwenden. Ich möchte eine Nachricht von einem Server (PHP-Datei) an mein Gerät (Android-Handy) sendenMit GCM, kein Fehler, aber keine Nachricht erhalten
Die Idee ist, die App zu starten, laden Sie test.php auf jedem Navigator (Chrome, Firefox ...) und dann Eine Benachrichtigung sollte auf meinem Telefon erscheinen. Eigentlich passiert nichts auf meinem Handy. Im Log von Android Studio kann ich das GCM-Registrierungs-Token sehen, also ist es in Ordnung. Aber nach ... bin ich ein wenig verloren. Wie kann ich überprüfen, ob die Nachricht an den Server gesendet wird? Wie kann ich wissen, dass der Dienst eine App abhört?
Hier ist meine aktuellen Dateien, ich habe keinen Fehler, wenn ich die Nachricht zu senden, und wenn ich die app starten:
test.php
<?php
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);
require_once __DIR__ . '/gcm.php';
$gcm = new GCM();
$data = array();
$data['message'] = "Un message de test";
// the topic you want to send notification
$topic = 'global';
// sending push message to a topic
$gcm->sendToTopic($topic, $data);
?>
gcm.php (Ich habe den API-Schlüssel entfernt von hier)
<?php
class GCM {
// constructor
function __construct() {
}
// sending push message to single user by gcm registration id
public function send($to, $message) {
$fields = array(
'to' => $to,
'data' => $message,
);
return $this->sendPushNotification($fields);
}
// Sending message to a topic by topic id
public function sendToTopic($to, $message) {
$fields = array(
'to' => '/topics/' . $to,
'data' => $message,
);
return $this->sendPushNotification($fields);
}
// sending push message to multiple users by gcm registration ids
public function sendMultiple($registration_ids, $message) {
$fields = array(
'registration_ids' => $registration_ids,
'data' => $message,
);
return $this->sendPushNotification($fields);
}
// function makes curl request to gcm servers
private function sendPushNotification($fields) {
// include config
// Set POST variables
$url = 'https://gcm-http.googleapis.com/gcm/send';
$headers = array(
'Authorization: key=AIz...',
'Content-Type: application/json'
);
// Open connection
$ch = curl_init();
// Set the url, number of POST vars, POST data
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Disabling SSL Certificate support temporarly
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
// Execute post
$result = curl_exec($ch);
if ($result === FALSE) {
die('Curl failed: ' . curl_error($ch));
}
// Close connection
curl_close($ch);
return $result;
}}?>
