How do you send a Slack Notification from a console command in Laravel?-CodePudding

It's very easy to send a Slack notification when a new record is created but how do you do it within an Artisan::command?

Kernel.php

$schedule->command('vacationReminder')->daily()->at('07:00');

console.php

Artisan::command('vacationReminder', function () {
    $this->notify(new VacationReminder());
})->purpose('Remind employees who is on vacation');

I know the above is wrong but what do I need to fire off the Slack notification from console.php? When I send from a model, for example, I need to import

use Illuminate\Notifications\Notifiable;
use App\Notifications\VacationReminder;

and have the function

public function routeNotificationForSlack($notification)
    {
        return env('SLACK_NOTIFICATION_WEBHOOK');
    }

How do these come into play when trying to send a notification from console.php?

CodePudding user response：

It is recommended to use a config file to access ENV variables (instead of using env() directly). Create a config file config/notifications.php with the following code:

<?php

return [
    'slack' => env('SLACK_NOTIFICATION_WEBHOOK')
];

You can later access the config variable using config('notifications.slack'). Then in your console.php you use the Notification facade and your VacationReminder notification by adding

use Illuminate\Support\Facades\Notification;
use App\Notifications\VacationReminder;

at the top. Finally, create your command:

Artisan::command('vacationReminder', function () {
    Notification::route('slack', config('notifications.slack'))
        ->notify(new VacationReminder());
})->describe('Remind employees who is on vacation');

This uses On-Demand Notifications so you don't need to have a model with the Notifiable trait.
