使用 @react-native-firebase/messaging 的 iOS 后台通知处理程序问题

Question

当应用程序处于后台或关闭状态时，我遇到这个问题。在所有情况下，通知都会显示在通知中心，但

messaging().setBackgroundMessageHandler

并不是每次都会被调用，而是在应用程序上严格检查时仅被调用几次。遵循云消息传递官方文档，将@react-native-firebase/messaging和

@react-native-firebase/app

升级到

版本10.2.0

。所有状态回调在Android中都工作正常，并且每次都完美获得，问题仅存在于iOS，并且不确定是什么导致了所有这些混乱。

在此处添加我正在使用的参考代码。 在入口文件中，即 index.js

messaging().setBackgroundMessageHandler(async (remoteMessage) => {
  console.log("Message handled in the background! 1", remoteMessage);
});

function HeadlessCheck({ isHeadless }) {
  if (isHeadless) {
    // App has been launched in the background by iOS, ignore
    return null;
  }
  return <App />;
}

AppRegistry.registerComponent(appName, () => HeadlessCheck);

在 App.js 中：

const App = () => {
  var notif = new NotifService();
  useEffect(() => {
    requestUserPermission()
    checkPermission()
    console.log("checkPermission")

    const unsubscribe = messaging().onMessage(async remoteMessage => {
      console.log("A new FCM message arrived!: foreground: ", remoteMessage)
      console.log("A new FCM message arrived!: foreground: ", remoteMessage.messageId)
      // Alert.alert('A new FCM message arrived!: foreground: ', JSON.stringify(remoteMessage));
      notif.localNotif();
    });
  
    return unsubscribe;
  }, []);

  useEffect(() => {
    messaging().onNotificationOpenedApp(remoteMessage => {
      console.log(
        'Notification caused app to open from background state:',
        remoteMessage.notification,
      );
      Alert.alert('Message handled in the background state!', JSON.stringify(remoteMessage));
      // navigation.navigate(remoteMessage.data.type);
    });
  
    // Check whether an initial notification is available
    messaging()
      .getInitialNotification()
      .then(remoteMessage => {
        if (remoteMessage) {
          console.log(
            'Notification caused app to open from quit state:',
            remoteMessage.notification,
          );
          Alert.alert('Message handled in the quit state!', JSON.stringify(remoteMessage));
          // setInitialRoute(remoteMessage.data.type); // e.g. "Settings"
        }
        // setLoading(false);
      });
  }, []);

  async function requestUserPermission() {
    const authStatus = await messaging().requestPermission();
    const enabled =
      authStatus === messaging.AuthorizationStatus.AUTHORIZED ||
      authStatus === messaging.AuthorizationStatus.PROVISIONAL;
  
    if (enabled) {
      console.log('Authorization status:', authStatus);
    }
  }

    // 1
    async function checkPermission() {
      const enabled = await messaging().hasPermission();
      console.log("checkPermission: enabled: ", enabled)
      if (enabled) {
        getToken();
      } else {
        requestPermission();
      }
    }
  
    // 3
    async function getToken() {
      let fcmToken = await AsyncStorage.getItem('fcmToken');
      console.log('fcmToken @@1:', fcmToken);
      if (!fcmToken) {
        fcmToken = await messaging().getToken();
        console.log('fcmToken @@2:', fcmToken);
        if (fcmToken) {
          // user has a device token
          await AsyncStorage.setItem('fcmToken', fcmToken);
        }
      }
    }
  
    // 2
    async function requestPermission() {
      console.log("requestPermission:")
      try {
        await messaging().requestPermission();
        // User has authorised
        getToken();
      } catch (error) {
        // User has rejected permissions
        console.log('permission rejected');
      }
    }
}

我使用 firebase Rest API 测试的

Payload：

{ "to": "TOKEN_HERE", "data": { "notification": { "title": "ABC1", "body": "xyz1" }, "Name": "121" }, "notification": { "title": "ABC1", "body": "xyz1" }, "priority": "high", "content_available": true }

如果有人遇到同样的问题并解决了，请在此处添加。现在已经被这个问题困住好几天了！谢谢。

使用@react-native-firebase/messaging的iOS后台通知处理程序问题

我在 IOS 中也面临这个问题需要帮助

改用新的 API onBackgroundMessage

Version 7.18.0 - August 13, 2020 Cloud Messaging
Deprecated setBackgroundMessageHandler. Use the new API onBackgroundMessage instead.
