Reactjs Web推送通知在使用firebase的react js中不起作用
我尝试在REact js项目中使用firebase实现web推送通知 Index.jsReactjs Web推送通知在使用firebase的react js中不起作用,reactjs,firebase,push-notification,react-redux,Reactjs,Firebase,Push Notification,React Redux,我尝试在REact js项目中使用firebase实现web推送通知 Index.js import React from "react"; import ReactDOM from "react-dom"; import "antd/dist/antd.css"; import './App.css'; import { createStore, compose, applyMiddleware } from "redux&

我正在端口3000上运行应用程序,我可以看到google chrome会抛出如下错误:
服务人员注册失败。我不知道我做错了什么。
你能帮我解决这个问题吗?另外,如果您需要我提供任何其他信息,请告诉我。1.您应该在firebase-messaging-sw.js中使用onBackgroundMessage,而不是setBackgroundMessageHandler 2.put 及 在firebase.js文件中 3.在serviceworker.register()之前调用index.js中的InitializeFileBase()和AskForPermissionReceiveNotifications() 它对我很有效
