如果您想继续原始 cURL 请求，您可以查看异步curl_multi_*函数 - 说实话，我已经有一段时间没有直接使用 cURL 了，所以我只参考PHP docs https://www.php.net/manual/en/function.curl-multi-init.php它还提供了一个可以用作模板的用法示例。
但是，我建议采取的方法是使用google/auth https://github.com/googleapis/google-auth-library-phpPHP 库，Guzzle HTTP 客户端 https://docs.guzzlephp.org/en/stable/验证并向 FCM API 发送请求，以及狂饮的承诺 https://github.com/guzzle/promises异步执行请求。
为了让事情变得“更糟”，您不仅必须使用 HTTP V1 端点，还必须使用HTTP V1 FCM 消息格式 https://firebase.google.com/docs/reference/fcm/rest/v1/projects.messages#Message以及。下面的代码显示了原始帖子中的消息将如何更改。
因此，以下是我如何在单个脚本的帮助下从头开始执行此操作Composer https://getcomposer.org:
# Initialize the project
mkdir myproject
cd myproject
composer require google/auth
<?php
# run.php
# This example uses Google Application Credentials exposed via the
# `GOOGLE_APPLICATION_CREDENTIALS` environment variable
# See https://github.com/googleapis/google-auth-library-php/blob/main/README.md
# for more alternative ways to authenticate requests
declare(strict_types=1);
require 'vendor/autoload.php';
use Google\Auth\ApplicationDefaultCredentials;
use GuzzleHttp\Client;
use GuzzleHttp\HandlerStack;
use GuzzleHttp\Promise;
### Create a Guzzle client that authenticates requests to the FCM API Endpoints
putenv('GOOGLE_APPLICATION_CREDENTIALS=/path/to/my/credentials.json');
// https://developers.google.com/identity/protocols/oauth2/scopes#fcm
$scopes = [
'https://www.googleapis.com/auth/cloud-platform',
'https://www.googleapis.com/auth/firebase.messaging',
];
// create middleware
$middleware = ApplicationDefaultCredentials::getMiddleware($scopes);
$stack = HandlerStack::create();
$stack->push($middleware);
$client = new Client([
'handler' => $stack,
'auth' => 'google_auth'
]);
### Setup the messages
$deviceTokens = [/* ... */];
$messages = [];
foreach ($deviceTokens as $token) {
$messages[] = [
'token' => $token,
'notification' => [
'title' => 'Notification Title',
'body' => 'Notification Body',
'image' => 'https://example.com/test.jpg',
],
'webpush' => [
'fcm_options' => [
'link' => 'https://example.com'
],
],
];
}
### Create message request promises
$promises = function() use ($client, $messages) {
foreach ($messages as $message) {
yield $client->requestAsync('POST', 'https://fcm.googleapis.com/v1/projects/my-app/messages:send', [
'json' => ['message' => $message],
]);
}
};
### Create response handler
$handleResponses = function (array $responses) {
foreach ($responses as $response) {
if ($response['state'] === Promise\PromiseInterface::FULFILLED) {
// $response['value'] is an instance of \Psr\Http\Message\RequestInterface
echo $response['value']->getBody();
} elseif ($response['state'] === Promise\PromiseInterface::REJECTED) {
// $response['reason'] is an exception
echo $response['reason']->getMessage();
}
}
};
Promise\Utils::settle($promises())
->then($handleResponses)
->wait();
我使用一个有效和一个无效的注册令牌测试了此脚本，并得到了以下结果：
❯ php run.php
Client error: `POST https://fcm.googleapis.com/v1/projects/beste-firebase/messages:send` resulted in a `400 Bad Request` response:
{
"error": {
"code": 400,
"message": "The registration token is not a valid FCM registration token",
"stat (truncated...)
{
"name": "projects/beste-firebase/messages/e39032c2-866d-4263-83e6-b1ce3770dfe6"
}
或者，如果您不想手动完成这一切，您也可以使用（非官方）Firebase 管理 PHP SDK https://github.com/kreait/firebase-php，切换到这种确切的方法
在最新的 7.5.0 版本中。 （免责声明：我是维护者，显然有偏见）：
# Initialize the project
mkdir myproject
cd myproject
composer require kreait/firebase-php
<?php
# run.php
# Again, this example uses Google Application Credentials exposed via the
# `GOOGLE_APPLICATION_CREDENTIALS` environment variable. The SDK picks
# them up automatically.
declare(strict_types=1);
require 'vendor/autoload.php';
use Kreait\Firebase\Factory;
### Initialize FCM
putenv('GOOGLE_APPLICATION_CREDENTIALS=/path/to/my/credentials.json');
$fcm = (new Factory())->createMessaging();
### Setup the message (without target)
$deviceTokens = [/* ... */];
$message = [
'notification' => [
'title' => 'Notification Title',
'body' => 'Notification Body',
'image' => 'https://example.com/test.jpg',
],
'webpush' => [
'fcm_options' => [
'link' => 'https://example.com'
],
],
];
### Send the message to the given tokens
$reports = $fcm->sendMulticast($message, $deviceTokens);
# https://firebase-php.readthedocs.io/en/stable/cloud-messaging.html#send-messages-to-multiple-devices-multicast
# goes more into detail what you can do with the reports
我希望这有帮助！
