基于Google‘s FCM实现消息推送

本文主要是介绍基于Google‘s FCM实现消息推送，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

当然，下面是一个简单的示例，演示了如何使用 Service Worker 和 Google's Firebase Cloud Messaging（FCM）来实现 Web 推送通知。

1. HTML 文件（`index.html`）

<!DOCTYPE html>
<html>
<head><title>FCM Push Notification Example</title><script src="https://www.gstatic.com/firebasejs/8.0.0/firebase-app.js"></script><script src="https://www.gstatic.com/firebasejs/8.0.0/firebase-messaging.js"></script>
</head>
<body><h1>Welcome to FCM Push Notification Example</h1><script src="main.js"></script>
</body>
</html>

2. 主 JavaScript 文件（`main.js`）

// Initialize Firebase
firebase.initializeApp({apiKey: "your-api-key",authDomain: "your-auth-domain",projectId: "your-project-id",messagingSenderId: "your-messaging-sender-id",appId: "your-app-id"
});const messaging = firebase.messaging();// Request permission and get token
Notification.requestPermission().then((permission) => {if (permission === 'granted') {messaging.getToken().then((currentToken) => {if (currentToken) {console.log('Token:', currentToken);// Send this token to your server} else {console.log('No registration token available. Request permission to generate one.');}}).catch((err) => {console.log('An error occurred while retrieving token. ', err);});}
});// Handle incoming messages
messaging.onMessage((payload) => {console.log('Message received:', payload);// Customize notification hereconst notificationTitle = payload.notification.title;const notificationOptions = {body: payload.notification.body,icon: payload.notification.icon};new Notification(notificationTitle, notificationOptions);
});

3. Service Worker 文件（`firebase-messaging-sw.js`）

// Import and configure the Firebase SDK
importScripts('https://www.gstatic.com/firebasejs/8.0.0/firebase-app.js');
importScripts('https://www.gstatic.com/firebasejs/8.0.0/firebase-messaging.js');firebase.initializeApp({apiKey: "your-api-key",authDomain: "your-auth-domain",projectId: "your-project-id",messagingSenderId: "your-messaging-sender-id",appId: "your-app-id"
});const messaging = firebase.messaging();// Handle background messages
messaging.onBackgroundMessage((payload) => {console.log('Received background message:', payload);const notificationTitle = payload.notification.title;const notificationOptions = {body: payload.notification.body,icon: payload.notification.icon};self.registration.showNotification(notificationTitle, notificationOptions);
});// Handle notification click
self.addEventListener('notificationclick', (event) => {event.notification.close();event.waitUntil(clients.openWindow('https://fbspider.com'));
});

4. 在服务器端发送推送

使用 cURL 或其他 HTTP 客户端发送一个 POST 请求：

curl -X POST "https://fcm.googleapis.com/fcm/send" \-H "Authorization: key=your-server-key" \-H "Content-Type: application/json" \-d '{"to": "client-token","notification": {"title": "Your Title","body": "Your Body","icon": "your-icon-url"}}'

这个示例包括：
