Push Notification Setup

推送通知设置

Implement push notifications across mobile and web platforms.

在移动和Web平台实现推送通知功能。

Firebase Cloud Messaging (React Native)

javascript

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

// Request permission
async function requestPermission() {
  const status = await messaging().requestPermission();
  if (status === messaging.AuthorizationStatus.AUTHORIZED) {
    const token = await messaging().getToken();
    await sendTokenToServer(token);
  }
}

// Handle foreground messages
messaging().onMessage(async message => {
  console.log('Foreground message:', message);
  showLocalNotification(message);
});

// Handle background/quit messages
messaging().setBackgroundMessageHandler(async message => {
  console.log('Background message:', message);
});

// Handle token refresh
messaging().onTokenRefresh(token => {
  sendTokenToServer(token);
});

    const token = await messaging().getToken();
    await sendTokenToServer(token);
  }
}

// Handle foreground messages
messaging().onMessage(async message => {
  console.log('Foreground message:', message);
  showLocalNotification(message);
});

// Handle background/quit messages
messaging().setBackgroundMessageHandler(async message => {
  console.log('Background message:', message);
});

// Handle token refresh
messaging().onTokenRefresh(token => {
  sendTokenToServer(token);
});

iOS Native (Swift)

swift

import UserNotifications

func requestAuthorization() {
    UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .badge, .sound]) { granted, error in
        if granted {
            DispatchQueue.main.async {
                UIApplication.shared.registerForRemoteNotifications()
            }
        }
    }
}

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    let token = deviceToken.map { String(format: "%02.2hhx", $0) }.joined()
    sendTokenToServer(token)
}

swift

import UserNotifications

    UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .badge, .sound]) { granted, error in
        if granted {
            DispatchQueue.main.async {
                UIApplication.shared.registerForRemoteNotifications()
            }
        }
    }
}

    let token = deviceToken.map { String(format: "%02.2hhx", $0) }.joined()
    sendTokenToServer(token)
}

Android (Kotlin)

kotlin

class MyFirebaseService : FirebaseMessagingService() {
    override fun onNewToken(token: String) {
        sendTokenToServer(token)
    }

    override fun onMessageReceived(message: RemoteMessage) {
        message.notification?.let {
            showNotification(it.title, it.body)
        }
    }

    private fun showNotification(title: String?, body: String?) {
        val channelId = "default"
        val notification = NotificationCompat.Builder(this, channelId)
            .setContentTitle(title)
            .setContentText(body)
            .setSmallIcon(R.drawable.ic_notification)
            .build()

        NotificationManagerCompat.from(this).notify(0, notification)
    }
}

    override fun onMessageReceived(message: RemoteMessage) {
        message.notification?.let {
            showNotification(it.title, it.body)

            .setContentTitle(title)
            .setContentText(body)
            .setSmallIcon(R.drawable.ic_notification)
            .build()

    }
}

Best Practices

最佳实践

Request permission at appropriate time
Handle token refresh
Support notification channels (Android)
Implement deep linking
Never send sensitive data in payload
Test on real devices

在合适的时机请求权限
处理Token刷新
支持通知渠道（Android）
实现深度链接
切勿在消息载荷中发送敏感数据
在真实设备上测试
