I'm trying to use the Google PHP API Client https://github.com/googleapis/google-api-php-client/ to send a FCM push notification through the Google HTTPv1 API.
require_once 'vendor/autoload.php'; //-- loading the google api client
putenv('GOOGLE_APPLICATION_CREDENTIALS=/path/to/service_account/key/project-sfk28as8ff.json');
$client = new Google_Client();
$client->useApplicationDefaultCredentials();
$client->addScope('https://www.googleapis.com/auth/firebase.messaging');
$httpClient = $client->authorize();
// Your Firebase project ID
$project = "push-test-5f923";
// Creates a notification for subscribers to the debug topic
$message = [
"message" => [
"token" => "cO5hrNMFKQI:APA91bFm.......6IYy1phlxIJx2ZNA1",
"notification" => [
"body" => "This is an FCM notification message!",
"title" => "FCM Message",
]
]
];
// Send the Push Notification - use $response to inspect success or errors
$response = $httpClient->post("https://fcm.googleapis.com/v1/projects/{$project}/messages:send", ['json' => $message]);
var_dump($response);
Here is the actual response:
object(GuzzleHttp\Psr7\Response)#61 (6) { ["reasonPhrase":"GuzzleHttp\Psr7\Response":private]=> string(9) "Forbidden" ["statusCode":"GuzzleHttp\Psr7\Response":private]=> int(403) ["headers":"GuzzleHttp\Psr7\Response":private]=> array(11) { ["Vary"]=> array(3) { [0]=> string(8) "X-Origin" [1]=> string(7) "Referer" [2]=> string(22) "Origin,Accept-Encoding" } ["Content-Type"]=> array(1) { [0]=> string(31) "application/json; charset=UTF-8" } ["Date"]=> array(1) { [0]=> string(29) "Thu, 27 Sep 2018 13:24:52 GMT" } ["Server"]=> array(1) { [0]=> string(3) "ESF" } ["Cache-Control"]=> array(1) { [0]=> string(7) "private" } ["X-XSS-Protection"]=> array(1) { [0]=> string(13) "1; mode=block" } ["X-Frame-Options"]=> array(1) { [0]=> string(10) "SAMEORIGIN" } ["X-Content-Type-Options"]=> array(1) { [0]=> string(7) "nosniff" } ["Alt-Svc"]=> array(1) { [0]=> string(40) "quic=":443"; ma=2592000; v="44,43,39,35"" } ["Accept-Ranges"]=> array(1) { [0]=> string(4) "none" } ["Transfer-Encoding"]=> array(1) { [0]=> string(7) "chunked" } } ["headerNames":"GuzzleHttp\Psr7\Response":private]=> array(11) { ["vary"]=> string(4) "Vary" ["content-type"]=> string(12) "Content-Type" ["date"]=> string(4) "Date" ["server"]=> string(6) "Server" ["cache-control"]=> string(13) "Cache-Control" ["x-xss-protection"]=> string(16) "X-XSS-Protection" ["x-frame-options"]=> string(15) "X-Frame-Options" ["x-content-type-options"]=> string(22) "X-Content-Type-Options" ["alt-svc"]=> string(7) "Alt-Svc" ["accept-ranges"]=> string(13) "Accept-Ranges" ["transfer-encoding"]=> string(17) "Transfer-Encoding" } ["protocol":"GuzzleHttp\Psr7\Response":private]=> string(3) "1.1" ["stream":"GuzzleHttp\Psr7\Response":private]=> object(GuzzleHttp\Psr7\Stream)#49 (7) { ["stream":"GuzzleHttp\Psr7\Stream":private]=> resource(31) of type (stream) ["size":"GuzzleHttp\Psr7\Stream":private]=> NULL ["seekable":"GuzzleHttp\Psr7\Stream":private]=> bool(true) ["readable":"GuzzleHttp\Psr7\Stream":private]=> bool(true) ["writable":"GuzzleHttp\Psr7\Stream":private]=> bool(true) ["uri":"GuzzleHttp\Psr7\Stream":private]=> string(10) "php://temp" ["customMetadata":"GuzzleHttp\Psr7\Stream":private]=> array(0) { } } }
The response I keep getting is basically Forbidden 403. ( I can also see it in the google developer console )
The Firebase Cloud Messaging API is enable in the Developer console as is Google Cloud Messaging (although it's not related). Now I figure this happens because I'm not doing the oAuth (not getting the access token) but I'm not sure how to get it as the google-api-php-client's documentation is not very detailed.
Can anyone tell me what functions are available in the google-api-php-client to get the one time access code that can then be consumed to get the access token for firebase so that I can then do the publish through cURL? (how to get a valid Oauth 2.0 token for the service account of the Firebase project)
