Cordova Android应用未从php脚本获得推送通知

Question

我有一个用Cordoava（v8.1.2）构建的android应用程序，正在尝试向其发送推送通知。

当我使用Google Firebase云消息传递实用程序进行测试时，我能够获得推送通知，即通知显示在手机屏幕上。

这说明我已经在Google Firebase控制台中正确设置了FCM消息传递。

但是，当我尝试通过php脚本（阵列中的'to'=>'/ topics / all'）发送推送通知时，消息已成功发送（返回消息为“ message_id”：8772623520092334112}，但我不要在同一部手机上收到推送通知。

这是我的index.js代码：

$fcmMsg = array(

$fcmFields = array(

curl_setopt( $ch,CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch,CURLOPT_SSL_VERIFYPEER, false );
curl_setopt( $ch,CURLOPT_POSTFIELDS, json_encode( $fcmFields ) );
$result = curl_exec($ch );
curl_close( $ch );
echo $result . "\n\n";
?>

我正处于智慧的尽头。有人可以启发我吗？
