我在android和iPhone中使用react-native-fcm进行远程通知.

react-native-fcm

在AndroID前台我无法在通知栏中收到远程通知.

在后台模式下,我能够成功获得通知,但前景中的一些内容却没有.

我在过去的两个月里遇到了这个问题并没有得到很好的解决方案,因为我做了很多新的尝试来解决问题,但最终没有取得任何成功.

解决方法:

根据官方Github的说法
react-native-fcm,
这个库是折旧的.
你可以使用
react-native-firebase
用于生成通知.
我能够在大约2个小时内获得通知工作.
如果你想要我可以分享它的代码.
祝好运.

更新 – 抱歉,由于我的办公室帐户,我之前无法回答.

这是我显示androID前台通知的代码.

firebase.messaging()        .subscribetotopic(this.state.user.user_name)        .then(response => console.log('response from FCM topIC' + response))        .catch(error =>  console.log('error from FCM topIC'+ error));        this.notificationListener = firebase.notifications().onNotification(notification => {            let notificationMessage = notification._androID._notification._data.action;            let recordID = notification._androID._notification._data.recordID;            let { Title, body } = notification;            //  console.log('ttttt', notification)            // notification.androID.setautoCancel(false)            console.log(Title, body, notificationMessage, recordID);            this.getinspectionUserLogs(this.state.user);            const channelID = new firebase.notifications.AndroID.Channel(                'Default',                'Default',                firebase.notifications.AndroID.importance.High            );            firebase.notifications().androID.createChannel(channelID);            let notification_to_be_displayed = new firebase.notifications.Notification({                data: notification._androID._notification._data,                sound: 'default',                show_in_foreground: true,                Title: notification.Title,                body: notification.body,            });            if (Platform.OS == 'androID') {                notification_to_be_displayed.androID                    .setPriority(firebase.notifications.AndroID.Priority.High)                    .androID.setChannelID('Default')                    .androID.setVibrate(1000);            }            console.log('FOREGROUND NOTIFICATION ListENER: \n', notification_to_be_displayed);            firebase.notifications().displayNotification(notification_to_be_displayed);        });
