Not receiving push notifications

[madsongr]

I'm sending push notifications with php script but I cannot receive them. I can register and get my token from fcm with success.

This is the payload result with success:

Result: {"multicast_id":5775932825803865467,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1514317072210466%e17bdb85f9fd7ecd"}]}

payload:

<?php

include_once("conn.php");

$sql = mysqli_query($mysqli, "SELECT token FROM tokens");

$registration_IDs = array();

while($row = mysqli_fetch_array($sql)){
	
	$registration_IDs[] = $row['token'];

}

$to = $registration_IDs;
var_dump($to);
echo '<br><br>';

// $title = "$get_title";
// $message = "$get_message";

$title = "Title";
$message = "Push notifications message";

sendPush($to,$title,$message);

function sendPush($to,$title,$message) {
// API access key from Google API's Console
// replace API
define( 'API_ACCESS_KEY', '*****************************************');
$registrationIds = $to;
$msg = array (
	'message' => $message,
	'title' => $title

// you can also add images, additionalData
);

$fields = array (
	'registration_ids' => $registrationIds,
	'data' => $msg
);

$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 );
	echo "Result: ". $result . "<br><br>";

Try sending a notification from the Firebase console https://console.firebase.google.com/
Set the target to be the whole app like below and see if the notifications are received then:

This way you can pinpoint the source of the problem - if the notification is received then you have to check your PHP script or the tokens used to target the specific devices. If the notification is not received, make sure there is no network firewall blocking the delivery on the device. Then check if the senderID in the push plugin configuration matches the sender ID in the Cloud Messaging settings in the Firebase console. Finally, check if you are using a recent version of the push plugin - version 0.2.0+ includes a some fixes Oreo devices that were not receiving notifications.

Ok, I can receive it from firebase console. But I really don't know what's wrong. PHP script is correct because it returns success: 1 and sender_id is the same as fcm.

[lini]

You should debug the script and find out exactly what headers and body it is sending. You can also try to send from the console using curl and compare the requests:

curl -X POST --header "Authorization: key=<SERVER_KEY_FROM_CLOUD_MESSAGING_SETTINGS_IN_FIREBASE_CONSOLE>" --Header "Content-Type: application/json" https://fcm.googleapis.com/fcm/send -d "{\"notification\":{\"title\": \"My title\", \"text\": \"My text\", \"badge\": \"1\", \"sound\": \"default\"}, \"data\":{\"foo\":\"bar\"}, \"priority\": \"High\", \"to\": \"<FCM_REGISTRATION_TOKEN_OF_DEVICE>\"}"

[madsongr]

@lini I pasted your curl code in linux console changing the credentials but nothing happens after pressing enter. It shows me a new line with >

[lini]

That's strange. The above command works in my console. For example:

curl -X POST --header "Authorization: key=AAAAAA" --Header "Content-Type: application/json" https://fcm.googleapis.com/fcm/send -d "{"notification":{"title": "My title", "text": "My text", "badge": "1", "sound": "default"}, "data":{"foo":"bar"}, "priority": "High", "to": "BBBBBB"}"

where AAAAAA is my server key and BBBBBB is the device registration token.

Make sure that you replace them correctly in the command - a new line starting with > indicates that you probably left a \ somewhere or replaced more than you should have.

I created a public gist with the command so it is easier to copy: https://gist.github.com/lini/688ce4f0f7dfc0dd7d061939f69fedcd

This one worked but gave me this error:

JSON_PARSING_ERROR: Unexpected character (n) at position 1.
curl: (3) Port number ended with ' '
curl: (3) [globbing] unmatched close brace/bracket in column 31

If I set "key" and "to" between <> it shows me:

bash: kOpmmaOIjlakmcGNWjQPMPzw:APA91bEfaTYF8mUZret4SN8UVoDa2YUdNxgEdwu-iABAGrxr9wijwENDZ0VVkbVWl1faeJvs7SIOwPZoyIKQvagNkGc9-qSS9LRFZfv: File or directory not found

[lini]

Github seems to be removing the backslashes used to escape the strings in the notification content of the command. Please use the Gist provided https://gist.github.com/lini/688ce4f0f7dfc0dd7d061939f69fedcd with the correct code.

Now it worked! Thanks for this tip. I don't know what's wrong with php script because it returns me the same success message.

I made some tests and working with push-plugin or firebase plugin the notification is received (I can get the log in console) but not displayed in android shade.

Sending with google's firebase console or curl x post:

• notification is displayed only in shade in background mode;

Sending with php script:

• notification is NOT displayed in shade even in background or foreground mode (I can only see the result in console.log);

We are facing same issue, from firebase its working but on base of curl request is not working
