I find it difficult to understand what exactly is happening with my Laravel application. It is fully functional locally (Mac, php 5.5.26), so I tested the application on my digital ocean droplet through the forge (php 5.6.15).
I use this package to send push notifications to a front end application that consumes my Laravel api. To speed up the execution of api calls, I delegated push notifications to the Laravel queue, which work fine in place, but I got this error when I tested the digital ocean.

I ran the text text and found that the serialized data part of this blob has a couple of differences that occur (as indicated in the error logs) in the ArrayIterator part. It seems that the difference comes from how the PushNotification :: DeviceCollection object is serialized, different from my local computer and from the server. In my testing, I hit the api endpoint locally and on the server with the same POST data to make sure the serialization output should be the same, but it is not.
I am not sure how to do this. I do not know if this is technically a bug with the PushNotification package (I have not seen error messages related to this problem), or if it is just something else that I am obscuring.
Also, just on the side of the note, I use a different queue to dispatch KeenIO events using a similar class structure like this Push structure and it doesn't have any problems, so I really feel like this should be a package problem PushNotification somehow ... Any thoughts ??
solvable
So this is a problem with the PHP version. My server worked on 5.6, and when I made another drop on PHP 7.0 and cloned the server, everything started working. I left the source server and worked so that it could function as a queue processor for push notifications using beanstalkd and it worked like a champion.
EDIT
I am using a supervisor to run the queue: work command. I launched
php artisan queue:restart
and I made sure that the manufacturing process was completely stopped when starting a new test by executing the kill command through the command line. Again, the desktop has no problems with my KeenIO jobs on the server, just the PushNotification jobs.
Here's the job class:
<?php namespace App\Jobs\Push; use Illuminate\Queue\SerializesModels; use Illuminate\Queue\InteractsWithQueue; use Illuminate\Contracts\Bus\SelfHandling; use Illuminate\Contracts\Queue\ShouldQueue; use App\Jobs\SendPushEvent; use App\Helpers\Push\PushFollow; class SendPushFollow extends SendPushEvent implements SelfHandling, ShouldQueue { use InteractsWithQueue, SerializesModels; private $push; public function __construct($follower, $followee) { $this->push = new PushFollow($follower, $followee); } public function handle(){ $this->push->send(); } }
And here is the PushFollow class, which has all the PushNotification logic in it.
<?php namespace App\Helpers\Push; use PushNotification; use App\Helpers\Push\Push; use Log; class PushFollow extends Push { public function __construct ($follower, $followee) { $_ios_devices = []; $_android_devices = []; $this->ios_count = 0; $this->android_count = 0; foreach($followee->devices as $_device){ if($_device->platform == "ios"){ $_ios_devices[] = PushNotification::Device($_device->identifier); $this->ios_count++; } elseif ($_device->platform == "android") { $_android_devices[] = PushNotification::Device($_device->identifier); $this->android_count++; } } Log::info('FINISHED BUILDING THE LISTS!!!'); $this->ios_devices = PushNotification::DeviceCollection($_ios_devices); $this->android_devices = PushNotification::DeviceCollection($_android_devices); Log::info('SET THE DEVICE COLLECTIONS'); $this->message = PushNotification::Message($follower->profile->name.' is now following you!',[ 'badge' => 1, 'sound' => 'example.aiff', 'actionLocKey' => 'Action button title!', 'locKey' => 'localized key', 'locArgs' => array( 'localized args', 'localized args', ), 'launchImage' => 'image.jpg', 'title' => env('APP_NAME').': New Follower', 'custom' => [], 'notId' => rand(1, 20), 'style' => 'inbox', 'ledColor' => [0, 0, 255, 0], 'vibrationPattern' => [500, 250, 500], ]); Log::info('SET THE MESSAGE'); } public function send () { Log::info('CALLING THE SEND METHOD'); if($this->android_count) { PushNotification::app(env('ANDROID_PUSH_NAME')) ->to($this->android_devices) ->send($this->message); } if($this->ios_count){ PushNotification::app(env('IOS_PUSH_NAME')) ->to($this->ios_devices) ->send($this->message); } } }
And here is the Push class, in which all my different push classes are extended.
<?php namespace App\Helpers\Push; abstract class Push { protected $ios_devices; protected $android_count; protected $ios_count; protected $android_devices; protected $message; }
Oh, as well as a stack trace.
