Php 使用laravel针对单个请求在移动设备上重复多次推送FCM通知

我有一个叫做userReqest的API。应用程序（android或ios）的用户发送请求，要求提供特定服务。每项服务都有许多提供者。因此，当我收到数据时，首先将其存储在DB中的请求表中，然后接受这个新请求，通过服务id获取该服务提供者的数据，然后将数据存储到发送的请求表中。之后，我应该向每个提供此服务的提供商发送通知，并向其发送一条消息“Youhaveanewrequest”，请求的信息除了通知部分外，其他一切似乎都正常，因为每个提供商都会在其客户端应用程序（android）上收到许多相同请求的通知消息。 我的API

public function userRequest(Request $request)

    # we have a push notification to mobile
    $userData = $request->all();
    $newRequest = UserRequest::create([

        'ServiceID'     => $userData['service_id'],
        'SubServiceID'  => $userData['subService_id'],
        'RequestNote'   => $userData['ServiceNote']
    ]);
    if($newRequest){
        $getdata = UserRequest::all()->last();
