GoogleCloudMessaging PHP script always returning invalidregistration

Question

I know there are lots of posts with the same issue, but after read all of them I could not find the reason of the problem.

I wrote a GCM client to register my device to receive messages from my server. It is working and I can store the registration ID in my database.

My problem is in the server side. I'm using a script found somewhere googling, but I always receive an error result:

{"multicast_id":7341760174206782539,"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"InvalidRegistration"}]}

The PHP code is (I'm using BROWSER API instead of SERVER API as told on tutorial, but trying both keys returns the same message):

<?php
// Replace with real BROWSER API key from Google APIs
$apiKey = "AIzaSyACln4edhSZW30XcmYpqoMz_gcRCC1iFjY";

// Replace with real client registration IDs 
$registrationIDs = array( "APA91bEdf1w4dQtsUqPT1jHhWEpvrpxzB1yrpL3RVtKrVxfzxfg2-Yl-pwHorsnmSnkqywQ8G90YcGEBoqCjgQU8CnjA0N7mOWF8bHMhHAs4ty46PPTX8yh6eSaSqvU3JTMmb-P0ma90EBG0rsQQbUh3aX895KxitI3LCiGOYqRfE5pZQ");

// Message to be sent
$message = "this is a test";

// Set POST variables
$url = 'https://android.googleapis.com/gcm/send';

$fields = array(
                'registration_ids'  => $registrationIDs,
                'data'              => array( "message" => $message ),
                );

$headers = array( 
                    'Authorization: key=' . $apiKey,
                    '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 );

curl_setopt( $ch, CURLOPT_POSTFIELDS, json_encode( $fields ) );

// Execute post
$result = curl_exec($ch);

// Close connection
curl_close($ch);

echo $result;
?>

I put the real ids and key to see if I'm doing right. Any ideas?

Solution 1

I had the same problem a couple of minutes ago.

Change this

$fields = array(
            'registration_ids'  => $registrationIDs,
            'data'              => array( "message" => $message ),
            );

to this:

$fields = array(
             'registration_ids'  => array($registrationIDs),
             'data'              => array( "message" => $message ),
             );

Solution 2

I found my problem. My PHP library removed some characters from post or get variables. And one of that characteres is '_', because it can be use as SQL injection. That was my problem. Fixed!

Solution 3

I got the same problem. My problem was my gcm_regid. The length of gcm_regid is 183 bytes. However my database use 150 bytes to store this value. Certainly the stored gcm_regid is incomplete. I fixed the problem by increase the storage size for the key. Then the problem solved.

You can use this code:

<?php

// API access key from Google API's Console
define( 'API_ACCESS_KEY', 'AIzaSyDiQ76wcVW2kcwIUQJasuym1JBXXXXX' );


$registrationIds = array( $_POST['id'] );

// prep the bundle
$msg = array
(
    'message'   => 'here is a message. message',
    'title'     => 'This is a title. title',
    'subtitle'  => 'This is a subtitle. subtitle',
    'tickerText'    => 'Ticker text here...Ticker text here...Ticker text here',
    'vibrate'   => 1,
    'sound'     => 1,
    'largeIcon' => 'large_icon',
    'smallIcon' => 'small_icon'
);

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

$headers = array
(
    'Authorization: key=' . API_ACCESS_KEY,
    'Content-Type: application/json'
);

$ch = curl_init();
curl_setopt( $ch,CURLOPT_URL, 'https://android.googleapis.com/gcm/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 $result.$registrationIds[0];

You can change notification to data as you wish.
