我已经将FCM与旧协议一起使用，但找不到任何具体文档来使用带有php的新FCM HTTP v1 API。
我已经设法将 Google API 客户端库导入我的项目，但找不到有关如何获取 fcm 消息所需范围的访问令牌的任何文档或教程。
也许有点晚了，但这是检索要与 FCM HTTP v1 API 一起使用的誓言令牌的方法。
- 下载这个谷歌库，在你的php代码中使用它。
- 从 Firebase 控制台生成并下载新的私钥
- 将此密钥以 json 格式存储在服务器上的安全位置。
如何使用您的私钥配置 Google 客户端
public function configureClient()
{
$client = new Google_Client();
try {
$client->setAuthConfig("include_your_private_json_key_path_here");
$client->addScope(Google_Service_FirebaseCloudMessaging::CLOUD_PLATFORM);
// retrieve the saved oauth token if it exists, you can save it on your database or in a secure place on your server
$savedTokenJson = $this->readFile();
if ($savedTokenJson != null) {
// the token exists, set it to the client and check if it's still valid
$client->setAccessToken($savedTokenJson);
if ($client->isAccessTokenExpired()) {
// the token is expired, generate a new token and set it to the client
$accessToken = $this->generateToken($client);
$client->setAccessToken($accessToken);
}
} else {
// the token doesn't exist, generate a new token and set it to the client
$accessToken = $this->generateToken($client);
$client->setAccessToken($accessToken);
}
$oauthToken = $accessToken["access_token"];
// the client is configured, now you can send the push notification using the $oauthToken.
} catch (Google_Exception $e) {
// handle exception
}
}
如何请求新的 oauth 令牌
private function generateToken($client)
{
$client->fetchAccessTokenWithAssertion();
$accessToken = $client->getAccessToken();
// save the oauth token json on your database or in a secure place on your server
$tokenJson = json_encode($accessToken);
$this->saveFile($tokenJson);
return $accessToken;
}
请注意，应实现saveFile()和readFile()方法，因为您希望存储和检索誓言令牌 json。按照有效负载结构的迁移指南进行操作。
如果您愿意使用现有的库而不是自己实现它，您可以考虑看看今天刚刚获得 FCM 支持的 https://github.com/kreait/firebase-php/。
https://firebase-php.readthedocs.io/en/latest/cloud-messaging.html
如果不适合您，您至少可以从源代码中提取与 FCM REST API 和 PHP 的连接。简而言之，这是 https://firebase.google.com/docs/reference/fcm/rest/v1/projects.messages 的实施。

批处理消息传递终结点已弃用，将于 2024 年 7 月删除。建议使用标准 v1 api send 方法循环访问令牌：https://firebase.google.com/docs/cloud-messaging/send-message#send-a-batch-of-messages
以下是有关如何向单个设备发送通知的示例：
<?php
require_once '<Path_to_google-api-php-client>/vendor/autoload.php';
function getOATHToken()
{
$client = new Google_Client();
try {
$client->setAuthConfig("<path_to_your_private_json_key.json>");
$client->addScope(Google_Service_FirebaseCloudMessaging::CLOUD_PLATFORM);
$savedTokenJson = readSavedToken();
if ($savedTokenJson) {
// the token exists, set it to the client and check if it's still valid
$client->setAccessToken($savedTokenJson);
$accessToken = $savedTokenJson;
if ($client->isAccessTokenExpired()) {
// the token is expired, generate a new token and set it to the client
$accessToken = generateToken($client);
$client->setAccessToken($accessToken);
}
} else {
// the token doesn't exist, generate a new token and set it to the client
$accessToken = generateToken($client);
$client->setAccessToken($accessToken);
}
$oauthToken = $accessToken["access_token"];
return $oauthToken;
} catch (Google_Exception $e) {}
return false;
}
//Using a simple file to cache and read the toke, can store it in a databse also
function readSavedToken() {
$tk = @file_get_contents('token.cache');
if ($tk) return json_decode($tk, true); else return false;
}
function writeToken($tk) {
file_put_contents("token.cache",$tk);
}
function generateToken($client)
{
$client->fetchAccessTokenWithAssertion();
$accessToken = $client->getAccessToken();
$tokenJson = json_encode($accessToken);
writeToken($tokenJson);
return $accessToken;
}
// Finally
function sendNotification($token, $title, $body, $accessToken) {
$payload = ["message" => ["token" => $token, "notification"=>["title" => $title, "body"=> $body]]];
$postdata = json_encode($payload);
$opts = array('http' =>
array(
'method' => 'POST',
'header' => 'Content-Type: application/json' . "rnAuthorization: Bearer $accessToken",
'content' => $postdata
)
);
$context = stream_context_create($opts);
$result = file_get_contents('https://fcm.googleapis.com/v1/projects/<your_firebase_project_id>/messages:send', false, $context);
echo "nn======RESPONSE======nn";
echo $result;

$token = "token-1"; //FCM Device token
$title = "Test from PHP";
$body = "This is a test from PHP";
sendNotification($token, $title, $body, getOATHToken());
