Create Controller & Add Method

Let’s create a notification controller into application. So to create need to run this artisan command.

$ php artisan make:controller NotificationController

After running this command, you will find a controller created at /app/Http/Controllers/NotificationController.php

Open up the file and paste the give code.

<?php
  
namespace App\Http\Controllers;
  
use Illuminate\Http\Request;
use App\Models\User;
  
class NotificationController extends Controller
{
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function send(Request $request)
    {
        return $this->sendNotification($request->device_token, array(
          "title" => "Sample Message", 
          "body" => "This is Test message body"
        ));
    }
  
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function sendNotification($device_token, $message)
    {
        $SERVER_API_KEY = '<YOUR-SERVER-API-KEY>';
  
        // payload data, it will vary according to requirement
        $data = [
            "to" => $device_token, // for single device id
            "notification" => $message
        ];
        $dataString = json_encode($data);
    
        $headers = [
            'Authorization: key=' . $SERVER_API_KEY,
            'Content-Type: application/json',
        ];
    
        $ch = curl_init();
      
        curl_setopt($ch, CURLOPT_URL, 'https://fcm.googleapis.com/fcm/send');
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $dataString);
               
        $response = curl_exec($ch);
      
        curl_close($ch);
      
        return $response;
    }
}

The above code will send notification to a single device ID which we will pass into request.

Let’s say that we want to send notifications to multiple devices

So how will we send ?

<?php
  
namespace App\Http\Controllers;
  
use Illuminate\Http\Request;
use App\Models\User;
  
class NotificationController extends Controller
{
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function send(Request $request)
    {
        return $this->sendNotification(array(
          $request->device_token1, 
          $request->device_token2,
          $request->device_token3
          //..
        ), array(
          "title" => "Sample Message", 
          "body" => "This is Test message body"
        ));
    }
  
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function sendNotification($device_tokens, $message)
    {
        $SERVER_API_KEY = '<YOUR-SERVER-API-KEY>';
  
        // payload data, it will vary according to requirement
        $data = [
            "registration_ids" => $device_tokens, // for multiple device ids
            "data" => $message
        ];
        $dataString = json_encode($data);
    
        $headers = [
            'Authorization: key=' . $SERVER_API_KEY,
            'Content-Type: application/json',
        ];
    
        $ch = curl_init();
      
        curl_setopt($ch, CURLOPT_URL, 'https://fcm.googleapis.com/fcm/send');
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $dataString);
               
        $response = curl_exec($ch);
      
        curl_close($ch);
      
        return $response;
    }
}

$data = [
    "to" => $device_token, // for single device id
    "data" => $message
];

$data = [
    "registration_ids" => $device_tokens, // for multiple device ids
    "data" => $message
];
