尝试向应用程序发送推送通知，但我需要用户的许可，但收到此错误消息： messages.requestPermission 不是一个函数，这是我的推送 notification.js 文件的代码

import * as  firebase from 'firebase/app';
import { getMessaging } from "firebase/messaging";
export const  initializeFirebase = () => {
  firebase.initializeApp({
    apiKey: "",
    authDomain: "",
    projectId: "pushnotification-9b180",
    storageBucket: "pushnotification-9b180.appspot.com",
    messagingSenderId: "878043563283",
    appId: "1:878043563283:web:c2a44f3c8b02ad8a17c6e6",
    measurementId: "G-GMWQKL94ZD"
  });
}
 
export const askForPermissionToReceiveNotifications = async () => {
    try {
      const messaging = getMessaging();

      await messaging.requestPermission();
      const token = await messaging.getToken();
      console.log('Your token is:', token);
      
      return token;
    } catch (error) {
      console.error(error);
    }
  }

你用的是react-native还是react？

但以反应本机的方式，你需要添加

import messaging from '@react-native-firebase/messaging';

你不需要的这一行

const messaging = getMessaging();

What are you using react-native or react?

but in react-native way you need add this line

import messaging from '@react-native-firebase/messaging';

you don´t need

const messaging = getMessaging();
