Laravel + Push 푸시알림 (http v1 버전)

1. 앱개발자에게 키정보 담긴 .json 파일 받아서 프로젝트 루트에 놓기

FIREBASE_CREDENTIALS=./service-account-file.json

 

2. services.php에 firebase 설정 추가

    "firebase" => [
        "credentials" => env("FIREBASE_CREDENTIALS", ""),
    ],

 

3. Pusher 모델 생성

<?php

namespace App\Models;

use App\Enums\TypeAlarm;
use Firebase\JWT\JWT;
use http\Client;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Facades\Http;

class Pusher extends Model
{
    public function sendNotification(Alarm $alarm)
    {
        $credentials = json_decode(file_get_contents(base_path(env('FIREBASE_CREDENTIALS'))), true);

        $client = new Client();

        $url = 'https://fcm.googleapis.com/v1/projects/' . $credentials['project_id'] . '/messages:send';

        $response = $client->post($url, [
            'headers' => [
                'Authorization' => 'Bearer ' . $this->getAccessToken($credentials),
                'Content-Type' => 'application/json',
            ],
            'json' => [
                'message' => [
                    'token' => $alram->user->push_token,
                    'notification' => [
                        'title' => 'Title',
                        'body' => 'Body',
                    ],
                   	'data' => [
                        'url' => 'https://example.com', // 클릭 시 이동할 URL
                    ],
                ],
            ],
        ]);

        if ($response->getStatusCode() == 200) {
            return response()->json(['message' => 'Notification sent successfully'], 200);
        } else {
            return response()->json(['message' => 'Failed to send notification'], 500);
        }
    }

    private function getAccessToken($credentials)
    {
        $client = new Client();

        $response = $client->post('https://oauth2.googleapis.com/token', [
            'json' => [
                'grant_type' => 'urn:ietf:params:oauth:grant-type:jwt-bearer',
                'assertion' => $this->createJwt($credentials),
            ],
        ]);

        $token = json_decode($response->getBody(), true);
        return $token['access_token'];
    }

    private function createJwt($credentials)
    {
        $now = time();
        $token = [
            'iss' => $credentials['client_email'],
            'sub' => $credentials['client_email'],
            'aud' => 'https://oauth2.googleapis.com/token',
            'iat' => $now,
            'exp' => $now + 3600,
            'scope' => 'https://www.googleapis.com/auth/firebase.messaging',
        ];

        return JWT::encode($token, $credentials['private_key'], 'RS256');
    }

}

 

4. 활용하기

$pusher = new Pusher();
$pusher->sendNotification($model);
