Flutter Firebase Messaging with PHP - php

Question

I have successfully sent push notification from Firebase console using FCM registration token. This is my dart file:
class PushNotificationsManager {
PushNotificationsManager._();
factory PushNotificationsManager() => _instance;
static final PushNotificationsManager _instance = PushNotificationsManager._();
final FirebaseMessaging _firebaseMessaging = FirebaseMessaging();
bool _initialized = false;
Future<void> init() async {
if (!_initialized) {
// For iOS request permission first.
_firebaseMessaging.requestNotificationPermissions();
_firebaseMessaging.configure();
// For testing purposes print the Firebase Messaging token
String token = await _firebaseMessaging.getToken();
print("FirebaseMessaging token: $token");
_initialized = true;
}
}
}
Now I would like to send the push notification using PHP. I found this tutorial. The PHP code is as below:
push.php
<?php
/**
* #author Ravi Tamada
* #link URL Tutorial link
*/
class Push {
// push message title
private $title;
private $message;
private $image;
// push message payload
private $data;
// flag indicating whether to show the push
// notification or not
// this flag will be useful when perform some opertation
// in background when push is recevied
private $is_background;
function __construct() {
}
public function setTitle($title) {
$this->title = $title;
}
public function setMessage($message) {
$this->message = $message;
}
public function setImage($imageUrl) {
$this->image = $imageUrl;
}
public function setPayload($data) {
$this->data = $data;
}
public function setIsBackground($is_background) {
$this->is_background = $is_background;
}
public function getPush() {
$res = array();
$res['data']['title'] = $this->title;
$res['data']['is_background'] = $this->is_background;
$res['data']['message'] = $this->message;
$res['data']['image'] = $this->image;
$res['data']['payload'] = $this->data;
$res['data']['timestamp'] = date('Y-m-d G:i:s');
return $res;
}
}
firebase.php
<?php
/**
* #author Ravi Tamada
* #link URL Tutorial link
*/
class Firebase {
// sending push message to single user by firebase reg id
public function send($to, $message) {
$fields = array(
'to' => $to,
'data' => $message,
);
return $this->sendPushNotification($fields);
}
// Sending message to a topic by topic name
public function sendToTopic($to, $message) {
$fields = array(
'to' => '/topics/' . $to,
'data' => $message,
);
return $this->sendPushNotification($fields);
}
// sending push message to multiple users by firebase registration ids
public function sendMultiple($registration_ids, $message) {
$fields = array(
'to' => $registration_ids,
'data' => $message,
);
return $this->sendPushNotification($fields);
}
// function makes curl request to firebase servers
private function sendPushNotification($fields) {
require_once __DIR__ . '/config.php';
// Set POST variables
$url = 'https://fcm.googleapis.com/fcm/send';
$headers = array(
'Authorization: key=' . FIREBASE_API_KEY,
'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;
}
}
?>
The web console show returned success message, but my device didn't get the notification. What went wrong?

Problem solved by using this PHP code
<?php
$url = "https://fcm.googleapis.com/fcm/send";
$token = "firebase token";
$serverKey = 'Server key';
$title = "Title";
$body = "Body";
$notification = array('title' =>$title , 'body' => $body, 'sound' => 'default', 'badge' => '1');
$arrayToSend = array('to' => $token, 'notification' => $notification,'priority'=>'high');
$json = json_encode($arrayToSend);
$headers = array();
$headers[] = 'Content-Type: application/json';
$headers[] = 'Authorization: key='. $serverKey;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST,"POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $json);
curl_setopt($ch, CURLOPT_HTTPHEADER,$headers);
//Send the request
$response = curl_exec($ch);
//Close request
if ($response === FALSE) {
die('FCM Send Error: ' . curl_error($ch));
}
curl_close($ch);
?>

try to configure your code as
protected function sendPushNotification($fields = array())
{
define( 'API_ACCESS_KEY', 'AAAA4-.....' );
$headers = array
(
'Authorization: key=' . API_ACCESS_KEY,
'Content-Type: application/json'
);
$ch = curl_init();
curl_setopt( $ch,CURLOPT_URL, 'https://fcm.googleapis.com/fcm/send' );
curl_setopt( $ch,CURLOPT_POST, true );
curl_setopt( $ch,CURLOPT_HTTPHEADER, $headers );
curl_setopt( $ch,CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch,CURLOPT_SSL_VERIFYPEER, false );
curl_setopt( $ch,CURLOPT_POSTFIELDS, json_encode( $fields ) );
$result = curl_exec($ch );
curl_close( $ch );
return $result;
}
and use it like:
$msg = array
(
'body' => 'your message',
'title' => "your app name",
'vibrate' => 1,
'sound' => 1,
);
$fields = array
(
'to' => '/topics/your topic name', // or 'to'=> 'phone token'
'notification'=> $msg
);
$this->sendPushNotification($fields);

If this helps,
You need to add the handlers for the notification under _firebaseMessaging.configure();
Have you done this anywhere -
_firebaseMessaging.configure
(
onMessage: (Map<String, dynamic> message) async
{
print("onMessage: $message");
},
onLaunch: (Map<String, dynamic> message) async // Called when app is terminated
{
print("onLaunch: $message");
},
onResume: (Map<String, dynamic> message) async
{
print("onResume: $message");
}
);
