   $url = 'https://fcm.googleapis.com/fcm/send';

   $fields = array (
        'registration_ids' => $id, //Device Ids
        'data' => array (

                 "additional_data"  =>$additional_data

   $result = curl_exec ( $ch );
   curl_close ( $ch );

【解决方案1】：

写这个：

使用安卓应用的fcm推送通知代码

我们已经创建了类：

通知类
令牌服务类

Fcm 通知服务类

public class NotificationService extends FirebaseMessagingService {
private static final String TAG = "FCM";

boolean notification, sound, vibration;

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    Log.d(TAG, remoteMessage.getNotification().getBody()+"");
    Log.d(TAG, remoteMessage.getNotification().getTitle()+"");
    Log.d(TAG, remoteMessage.getFrom()+"");
    Log.d(TAG, remoteMessage.getData()+"");
    addNotification(remoteMessage.getNotification());
}
private void addNotification(RemoteMessage.Notification data) {
    NotificationCompat.Builder builder =
            new NotificationCompat.Builder(this)
                    .setSmallIcon(R.drawable.icon)  // add icon 
                    .setContentTitle(data.getTitle()+"")
                    .setAutoCancel(true)
                    .setContentText(data.getBody()+"");
    Notification notification = new Notification();

    if (sound)
        notification.defaults |= Notification.DEFAULT_SOUND;

    if (vibration)
        notification.defaults |= Notification.DEFAULT_VIBRATE;

    builder.setDefaults(notification.defaults);
    Intent notificationIntent = new Intent(this, Service_confirmedActivity.class);
    PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent,
            PendingIntent.FLAG_ONE_SHOT);
    builder.setContentIntent(contentIntent);

    // Add as notification
    NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    manager.notify(0, builder.build());
}
  }

令牌服务类

public class TokenService extends FirebaseInstanceIdService {
private static final String TAG = "FirebaseIDService";
public static String DeviceToc = "";
@Override
public void onTokenRefresh() {
    // Get updated InstanceID token.
    String refreshedToken = FirebaseInstanceId.getInstance().getToken();
    Log.e(TAG, "Refreshed token: " + refreshedToken);

    DeviceToc = refreshedToken;
    Log.e("DeviceToc",""+refreshedToken);
    sendRegistrationToServer(refreshedToken);
}

private void sendRegistrationToServer(String token) {

    SharedPreferences pref = getApplicationContext().getSharedPreferences("MyPref", 0);

    SharedPreferences.Editor editor = pref.edit();
    editor.putString("deviceToc",token); // Storing string
    editor.commit();

    Log.i("token",""+token);

  }
  }
