Laravel Expo Push Notification - Not receiving Notification on Android

问题

I am quite new to Laravel and couldn't find any practical example of the library https://github.com/Alymosul/laravel-exponent-push-notifications. I want to create a simple Welcome-Notification.

My Notification looks like this:

<?php

namespace App\Notifications;

use Illuminate\Bus\Queueable;
use Illuminate\Notifications\Notification;
use NotificationChannels\ExpoPushNotifications\ExpoChannel;
use NotificationChannels\ExpoPushNotifications\ExpoMessage;

class WelcomeNotification extends Notification
{
    use Queueable;

    public function __construct(){
    }

    public function via($notifiable)
    {
        return [ExpoChannel::class];
    }

    public function toExpoPush($notifiable)
    {
        return ExpoMessage::create()
            ->badge(1)
            ->title("Hello World!")
            ->enableSound()
            ->body("Hello World!");
    }

    public function toArray($notifiable)
    {
        return [
        ];
    }
}

I already subscribed a user with the help of the subscribe route (successfully created an DB entry).

Now i want to send the notification to the user:

public function sendNotification(Request $request)
{
        $getUserByEmail = User::where('email', 'user@email.com')->first();
        $getUserByEmail->notify(new WelcomeNotification());
}

I didn't receive the notification. When using the expo notification tool it works as expected.

Could you please explain to me what am I doing wrong?

回答1:

I figured it out. The problem is, that the library laravel-exponent-push-notifications is sending all notifications without a message-channel to the channel 'Default'.

So it would work if i create the message-channel 'Default' on the device.

Alternatively there are two more options:

Option 1: Create a message channel on the device.

import { Notifications } from 'expo';

    if (Platform.OS === 'android') {
        await Notifications.createChannelAndroidAsync('chat-messages', {
            name: 'Chat messages',
            sound: true,
        });
    }

Send the notification

$getUserByEmail = User::where('email', 'user@email.com')->first();
$getUserByEmail->notify(new WelcomeNotification());

The notification should contain the message channel, registered on the device:

public function toExpoPush($notifiable){
        return ExpoMessage::create()
            ->badge(1)
            ->title("Hello World!")
            ->enableSound()
            ->body("Hello World!")
            ->setChannelId("chat-messages");
}

Option 2: Change the toArray()-method in the file NotificationChannels\ExpoPushNotifications\ ExpoMessage.php to something like this:

    public function toArray()
    {

        $returnArray = [
            'title'     =>  $this->title,
            'body'      =>  $this->body,
            'sound'     =>  $this->sound,
            'badge'     =>  $this->badge,
            'ttl'       =>  $this->ttl,
            'channelId' => $this->channelId,
            'data'      => $this->jsonData,
        ];

        if (strtolower($this->channelId) == 'default' || $this->channelId == '') {
            unset($returnArray['channelId']);
        }

        return $returnArray;
    }

When sending notifications to the expo application without a channel, expo is automatically creating a channel and you will receive the notification.
