FCM始终响应[404]

Question

我遇到一个奇怪的问题，我不知道该如何解决。我正在尝试使用Firebase云消息传递将推送通知发送到设备。即使使用Google API，我也无法发送它。 Firebase始终会回答“ 404 / v1 / my-app / messages：在此服务器上未找到发送”，这就是我们所知道的。下面是我的代码

class PushNotification {

    static private $firebase_message = NULL;

    public static function get_instance()
    {
        putenv('GOOGLE_APPLICATION_CREDENTIALS='.APPPATH.DIRECTORY_SEPARATOR.'config'.DIRECTORY_SEPARATOR.'credentials.json');

        if ( ! empty($firebase_message))
            return self::$firebase_message;

        $client = new Google_Client();

        $client->useApplicationDefaultCredentials();
        $client->setScopes(Google_Service_FirebaseCloudMessaging::CLOUD_PLATFORM);
//
//      $client->authorize();
        //$client->setDeveloperKey(Kohana::$config->load('firebase.key'));

        self::$firebase_message = new Google_Service_FirebaseCloudMessaging($client);

        return self::$firebase_message;
    }

    private static function _init_request($params)
    {
        $request = new Google_Service_FirebaseCloudMessaging_SendMessageRequest();
        $message = new Google_Service_FirebaseCloudMessaging_Message();
        $notification = new Google_Service_FirebaseCloudMessaging_Notification();


        if (empty($params['body']) || empty($params['title']))
            throw new Kohana_Exception();


        $notification->setBody($params['body']);
        $notification->setTitle($params['title']);

        if ( ! empty($params['topic']))
        {
            $message->setTopic($params['topic']);
        }

        if ( ! empty($params['token']))
        {
            $message->setToken($params['token']);
        }

        $message->setData($params['data']);

        $message->setNotification($notification);

        $request->setMessage($message);

        return $request;
    }

    public static function send_message_to_topic($topic, $body, $title, $data = [])
    {
        try
        {
            $project_id = Kohana::$config->load('firebase.project_id');
            /** @var Google_Service_FirebaseCloudMessaging $fcm */
            $fcm = self::get_instance();

            $request = self::_init_request([
                'topic' => $topic,
                'body'  => $body,
                'title' => $title,
                'data'  => $data
            ]);

            $fcm->projects_messages->send($project_id, $request);
        }
        catch (Exception $exception)
        {
            echo $exception->getMessage();
            return FALSE;
        }

        return TRUE;
    }

    public static function send_message_to_device($device_token, $body, $title, $data = [])
    {
        try
        {
            $project_id = Kohana::$config->load('firebase.project_id');
            /** @var Google_Service_FirebaseCloudMessaging $fcm */
            $fcm = self::get_instance();

            $request = self::_init_request([
                'token' => $device_token,
                'body'  => $body,
                'title' => $title,
                'data'  => $data
            ]);

            $fcm->projects_messages->send($project_id, $request);
        }
        catch (Exception $exception)
        {
            echo $exception->getMessage();
            return FALSE;
        }
        return TRUE;
    }

    public static function set_conditional_message($condition, $body, $title, $data = [])
    {
        try
        {
            $project_id = Kohana::$config->load('firebase.project_id');
            /** @var Google_Service_FirebaseCloudMessaging $fcm */
            $fcm = self::get_instance();

            $request = self::_init_request([
                'condition' => $condition,
                'body'      => $body,
                'title'     => $title,
                'data'      => $data
            ]);

            $fcm->projects_messages->send($project_id, $request);
        }
        catch (Exception $exception)
        {
            return FALSE;
        }

        return TRUE;
    }
}

这就是我所说的：

        $token = 'TOKEN_ID';

        PushNotification::send_message_to_device($token, 'Test body', 'Test title');
