使用广播频道与Firebase-SW通信，并反应组件不起作用

Question

我正在尝试使用Firebase SW中的广播频道在OnbackgroundMessage中发布消息，这是服务工作者中的代码：

messaging.onBackgroundMessage(function (payload) {
 console.log("Received background message ", payload);

 const notificationTitle = payload.notification.title;
 const notificationOptions = {
  body: payload.notification.body,
  icon: "/logo192.png",
 };
 //BROADCAST
 const broadcast = new BroadcastChannel("background-message");
 broadcast.postMessage("broadcast payload");

 return self.registration.showNotification(
 notificationTitle,
 notificationOptions
);

}）;

在app.js文件中，我设置了Listner，以使用Redux派遣通知的有效载荷：

const broadcast = new BroadcastChannel("background-message");
  broadcast.onmessage = (event) => {
    console.log("broadcast message:", event.data);
    dispatch(getNotifications(event.data));
  };

我尝试推出测试通知，但它不起作用
