Pushok is a simple PHP library for sending push notifications to APNs. 

## Features

- [X] Uses new Apple APNs HTTP/2 connection
- [X] Supports JWT-based authentication
- [X] Supports Certificate-based authentication
- [X] Supports new iOS 10 features such as Collapse IDs, Subtitles and Mutable Notifications
- [X] Uses concurrent requests to APNs
- [X] Tested and working in APNs production environment

## Requirements

* PHP >= 8.1
* lib-curl >= 7.46.0 (with http/2 support enabled)
* lib-openssl >= 1.0.2e 

Docker image that meets requirements can be found [here](https://hub.docker.com/r/edamov/pushok-docker).
Or you can follow [this tutorial](https://nathanleclaire.com/blog/2016/08/11/curl-with-http2-support---a-minimal-alpine-based-docker-image/) to create your own docker image with curl with HTTP/2 support.

## Install

Via Composer

``` bash
$ composer require edamov/pushok
```

## Getting Started

Using JWT token. See [Handling Notification Responses from APNs](https://developer.apple.com/documentation/usernotifications/setting_up_a_remote_notification_server/handling_notification_responses_from_apns) for more info.
``` php
<?php
require __DIR__ . '/vendor/autoload.php';

use Pushok\AuthProvider;
use Pushok\Client;
use Pushok\Notification;
use Pushok\Payload;
use Pushok\Payload\Alert;

$options = [
    'key_id' => 'AAAABBBBCC', // The Key ID obtained from Apple developer account
    'team_id' => 'DDDDEEEEFF', // The Team ID obtained from Apple developer account
    'app_bundle_id' => 'com.app.Test', // The bundle ID for app obtained from Apple developer account
    'private_key_path' => __DIR__ . '/private_key.p8', // Path to private key
    'private_key_secret' => null // Private key secret
];

// Be aware of thing that Token will stale after one hour, so you should generate it again.
// Can be useful when trying to send pushes during long-running tasks
$authProvider = AuthProvider\Token::create($options);

$alert = Alert::create()->setTitle('Hello!');
$alert = $alert->setBody('First push notification');

$payload = Payload::create()->setAlert($alert);

//set notification sound to default
$payload->setSound('default');

//add custom value to your notification, needs to be customized
$payload->setCustomValue('key', 'value');

$deviceTokens = ['<device_token_1>', '<device_token_2>', '<device_token_3>'];

$notifications = [];
foreach ($deviceTokens as $deviceToken) {
    $notifications[] = new Notification($payload,$deviceToken);
}

// If you have issues with ssl-verification, you can temporarily disable it. Please see attached note.
// Disable ssl verification
// $client = new Client($authProvider, $production = false, [CURLOPT_SSL_VERIFYPEER=>false] );
$client = new Client($authProvider, $production = false);
$client->addNotifications($notifications);



$responses = $client->push(); // returns an array of ApnsResponseInterface (one Response per Notification)

foreach ($responses as $response) {
    // The device token
    $response->getDeviceToken();
    // A canonical UUID that is the unique ID for the notification. E.g. 123e4567-e89b-12d3-a456-4266554400a0
    $response->getApnsId();
    
    // Status code. E.g. 200 (Success), 410 (The device token is no longer active for the topic.)
    $response->getStatusCode();
    // E.g. The device token is no longer active for the topic.
    $response->getReasonPhrase();
    // E.g. Unregistered
    $response->getErrorReason();
    // E.g. The device token is inactive for the specified topic.
    $response->getErrorDescription();
    $response->get410Timestamp();
}
```

Using Certificate (.pem). Only the initilization differs from JWT code (above). Remember to include the rest of the code by yourself.

``` php
<?php

$options = [
    'app_bundle_id' => 'com.app.Test', // The bundle ID for app obtained from Apple developer account
    'certificate_path' => __DIR__ . '/private_key.pem', // Path to private key
    'certificate_secret' => null // Private key secret
];

$authProvider = AuthProvider\Certificate::create($options);

...

```
Note : Please see [this post](https://github.com/edamov/pushok/issues/124) about ssl verification

Options to fiddle around. See [Sending Notification Requests to APNs](https://developer.apple.com/documentation/usernotifications/setting_up_a_remote_notification_server/sending_notification_requests_to_apns)
``` php
<?php

$client = new Client($authProvider, $production = false);
$client->addNotifications($notifications);


// Set the number of concurrent requests sent through the multiplexed connections. Default : 20
$client->setNbConcurrentRequests( 40 );

// Set the number of maximum concurrent connections established to the APNS servers. Default : 1
$client->setMaxConcurrentConnections( 5 );


$responses = $client->push();

```

## Testing

``` bash
$ composer test
```
