向 firebase 发送请求时令牌无效

问：

我正在Symfony网站上工作，并希望在生成令牌并向firebase服务器发送请求时推送通知。然后它说令牌无效。

我正在像这样生成令牌。

use Firebase\JWT\JWT;
use Doctrine\ORM\EntityManagerInterface;
use Kreait\Firebase\Factory;
use Kreait\Firebase\Messaging\CloudMessage;
use Kreait\Firebase\Messaging\Notification;
use Kreait\Firebase\ServiceAccount;

    $driver_id = $driver->getId();
     
    $serviceAccount = ServiceAccount::fromValue(__DIR__.'/../../../firebase_credentials.json');
    
    $firebase = (new Factory)
    ->withServiceAccount($serviceAccount)
    ->createDatabase();

    $payload = [
        'iss' => $serviceAccount->getClientEmail(),
        'sub' => $serviceAccount->getClientEmail(),
        'aud' => 'https://identitytoolkit.googleapis.com/google.identity.identitytoolkit.v1.IdentityToolkit',
        'iat' => time(),
        'exp' => time() + 60 * 60, // Set the expiration time to one hour from now
        'uid' => $driver_id, // Set the UID to the driver's ID
    ];

    $privateKey = $serviceAccount->getPrivateKey();
    $token = JWT::encode($payload, $privateKey, 'RS256');
        
        // save the browser token to the database
        $driver->setBrowserToken($token);
        $token = $driver->getBrowserToken();

在这里，我调用了向火力基地发送请求的方法

 $title = 'New trip assign to you.';
 $message = $dispatcherName . ' is assign new trip to you.';
 if (!empty($token)) {
            
            $response = $this->forward('App\Controller\SendNotification::webNotification', [
                'token' =>  $token,
                'title' => $title,
                'message' =>$message
            ]);
        }

这是向服务器发送请求的方法

 public function webNotification( $token, $title, $message)
 {
   
    $msg = array(
        'title' => $title,
        'body' => $message,
        'icon' => 'myicon',/*Default Icon*/
        'sound' => 'mySound',/*Default sound*/
        'click_action' => 'FLUTTER_NOTIFICATION_CLICK', /*Action when notification is clicked*/
        'data' => array(
            'message' => $message,
            'title' => $title
        )
    );
    
 
     $fields = array(
         'to' => array($token),
         'data' => array('notification' => $msg)
     );
 
     $headers = array(
         'Authorization: key=' . $_ENV['FIREBASE_SERVER_KEY']
     );
 
     try {
         // Send notification to Firebase Cloud Messaging server
         $ch = curl_init();
         curl_setopt($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_RETURNTRANSFER, true);
         curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
         curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
         
         $result = curl_exec($ch);
 
         if ($result === false) {
             throw new \Exception(curl_error($ch));
         }

通过使用dd（$result），我得到了这个结果

"{"multicast_id":3241703823291433054,"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"InvalidRegistration"}]}"
