我正在尝试将我的 FCM 从旧版迁移到 http v1。我已经按照此处的文档进行操作，https://firebase.google.com/docs/cloud-messaging/migrate-v1，下载了 Firebase 管理 SDK 并安装了适用于 PHP 7.4 的 google API (https://github.com /googleapis/google-api-php-client）。然而，它没有按预期工作，我已经尝试了几天才能使其工作。有人可以指出我在这里做错了什么吗？

顺便说一下，我需要从网络向用户 Android 设备发送通知。生成的设备令牌并保存在数据库中。我还在学习中，所以请耐心等待。

我正在与您分享我如何解决这个问题。

我在这个演示中使用 Laravel 10

首先你需要使用composer安装适用于PHP的Google Auth Library

composer require google/auth 生成您的 Firebase 帐户 Json 凭据：

复制您下载的 Json 或 Firebase 帐户常规设置中的 Firebase 项目 ID

将您的 json 凭证保存在项目中安全的地方。

现在使用此代码片段并根据您的用途进行调整

<?php
namespace App\CustomClass;

use App\Models\Configuration;
use Google\Auth\Credentials\ServiceAccountCredentials;
use Google\Auth\HttpHandler\HttpHandlerFactory;

class FireBasePushNotification
{

private $url = 'https://fcm.googleapis.com/v1/projects/<PROJECT_ID_HERE>/messages:send';
private $scope = "https://www.googleapis.com/auth/firebase.messaging";
private $token;

public function __construct()
{
    $config = Configuration::first(); // I stored my json token in database

// Provide the path where you stored the json token, in my case, I stored it in database        
$creadentials = new ServiceAccountCredentials($this->scope, $config->firebase_service);
    $this->token = $creadentials->fetchAuthToken(HttpHandlerFactory::build());
}

public function to($device, $body, $title = "My favorite App")
{
    $data = [
        'token' => $device,
        'title' => $title,
        'body' => $body
    ];

    return $this->send($data);
}

public function send($data)
{
    $headers = [
        'Authorization: Bearer ' . $this->token['access_token'],
        'Content-Type: application/json'
    ];

    $fields = [
        'message' => [
            'token' => $data['token'],
            'notification' => [
                'title' => $data['title'],
                'body' => $data['body']
            ]
        ]
    ];

    $fields = json_encode($fields);

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $this->url);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);

    $result = curl_exec($ch);
    curl_close($ch);

    return $result;
}

}

我希望这可以帮助你，同时也帮助其他人
