firebase_messaging onResume和onLaunch无法正常工作 [英] firebase_messaging onResume and onLaunch not working
本文介绍了firebase_messaging onResume和onLaunch无法正常工作的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
当应用程序处于前台时，我收到通知，但当应用程序在后台时，我没有收到通知.另外，我在google-ed/StackOverflow-ed中工作了2个小时或更长时间，但能够解决此问题.
我的配置是:
firebase_auth: ^0.10.0
firebase_messaging: ^5.0.0
清单是这样的:
代码如下:
final notifications = new FirebaseMessaging();
class AppNotifications {
static String fcmToken = '';
static Future<Null> init() async {
appLogs("AppNotifications init");
notifications.requestNotificationPermissions(const IosNotificationSettings(sound: true, badge: true, alert: true));
await configure();
fcmToken = await notifications.getToken();
appLogs("FCM TOKEN : " + fcmToken);
notifications.onTokenRefresh.listen((newToken) {
fcmToken = newToken;
appLogs("FCM TOKEN onTokenRefresh: " + fcmToken);
});
await updateFCMToken();
}
static Future<Null> configure() async {
appLogs("AppNotifications Configure");
notifications.configure(onMessage: (msg) {
appLogs('FCM onMessage: ' + msg.toString());
}, onLaunch: (lun) {
appLogs('FCM onLaunch: ' + lun.toString());
}, onResume: (res) {
appLogs('FCM onResume: ' + res.toString());
});
}
static Future<Null> updateFCMToken() async {
auth.currentUser.fcmToken = fcmToken;
await updateUserInSharedPreference();
}
}
我正在这样调用函数:
class HomeScreenState extends State<HomeScreen> {
@override
void initState() {
super.initState();
Future.delayed(Duration(milliseconds: 100), () async {
await AppNotifications.init();
});
}
..... ....
我正在使用邮递员发送通知:
我的日志:
**(App is Foreground)** I/flutter (31888): APPLOGS : FCM onMessage: {notification: {title: Test notification title, body: Test notification body}, data: {status: done, id: 1, foo: bar, click_action: FLUTTER_NOTIFICATION_CLICK}}
**(App is Background)** W/FirebaseMessaging(31888): Missing Default Notification Channel metadata in AndroidManifest. Default value will be used.

解决方案
我花了2天的时间解决此问题，可能对您有所帮助. 通知标签仅用于显示通知.您只能访问onResume/onLaunch上的数据内容.
如果您要在onResume/onLaunch中处理通知消息，请将这些消息也添加到 data 标记中，那么您就可以做任何您想做的事情.
发送此通知消息
{
"notification": {
"body": "body",
"title": "title"
},
"priority": "high",
"data": {
"body": "body",
"title": "title"
"click_action": "FLUTTER_NOTIFICATION_CLICK",
"id": "1",
"status": "done",
"image": "https://ibin.co/2t1lLdpfS06F.png",
},
"to": <your token>
}
您将收到有关恢复或启动的以下信息，您的通知标签此处为空
{notification: {}, data: {image: https://ibin.co/2t1lLdpfS06F.png, google.original_priority: high, google.sent_time: 1560858283888, google.delivered_priority: high, body: body , title: title, click_action: FLUTTER_NOTIFICATION_CLICK, google.message_id: 0:1560858283908500%eefdc741eefdc741, collapse_key: <package>, google.ttl: 2419200, from: <from>, id: 1, status: done}}
您可以使用添加在数据标记中的标题和正文.
I am getting the notification when the app is in the foreground but not when the app in the background. Also, I have google-ed/StackOverflow-ed for like 2 hours or more but able to resolves this.
My Configurations are :
firebase_auth: ^0.10.0
firebase_messaging: ^5.0.0
The manifest is like this:
The code is like this:
final notifications = new FirebaseMessaging();
class AppNotifications {
static String fcmToken = '';
static Future<Null> init() async {
appLogs("AppNotifications init");
notifications.requestNotificationPermissions(const IosNotificationSettings(sound: true, badge: true, alert: true));
await configure();
fcmToken = await notifications.getToken();
appLogs("FCM TOKEN : " + fcmToken);
notifications.onTokenRefresh.listen((newToken) {
fcmToken = newToken;
appLogs("FCM TOKEN onTokenRefresh: " + fcmToken);
});
await updateFCMToken();
}
static Future<Null> configure() async {
appLogs("AppNotifications Configure");
notifications.configure(onMessage: (msg) {
appLogs('FCM onMessage: ' + msg.toString());
}, onLaunch: (lun) {
appLogs('FCM onLaunch: ' + lun.toString());
}, onResume: (res) {
appLogs('FCM onResume: ' + res.toString());
});
}
static Future<Null> updateFCMToken() async {
auth.currentUser.fcmToken = fcmToken;
await updateUserInSharedPreference();
}
}
I am calling the function like this:
class HomeScreenState extends State<HomeScreen> {
@override
void initState() {
super.initState();
Future.delayed(Duration(milliseconds: 100), () async {
await AppNotifications.init();
});
}
..... ....
I am using postman for sending the notification :
My logs :
**(App is Foreground)** I/flutter (31888): APPLOGS : FCM onMessage: {notification: {title: Test notification title, body: Test notification body}, data: {status: done, id: 1, foo: bar, click_action: FLUTTER_NOTIFICATION_CLICK}}
**(App is Background)** W/FirebaseMessaging(31888): Missing Default Notification Channel metadata in AndroidManifest. Default value will be used.

解决方案
lost my 2 days to fix this issue, it may helpful for you. notification tag only for showing notification. you can access only data content on onResume/onLaunch.
If you want handle notification message inside onResume/onLaunch add those messages in data tag also, Then you can do what ever you want.
refer more detail on this link
send this notification message
{
"notification": {
"body": "body",
"title": "title"
},
"priority": "high",
"data": {
"body": "body",
"title": "title"
"click_action": "FLUTTER_NOTIFICATION_CLICK",
"id": "1",
"status": "done",
"image": "https://ibin.co/2t1lLdpfS06F.png",
},
"to": <your token>
}
you will receive below information onResume or onLaunch, your notification tag will be empty here
{notification: {}, data: {image: https://ibin.co/2t1lLdpfS06F.png, google.original_priority: high, google.sent_time: 1560858283888, google.delivered_priority: high, body: body , title: title, click_action: FLUTTER_NOTIFICATION_CLICK, google.message_id: 0:1560858283908500%eefdc741eefdc741, collapse_key: <package>, google.ttl: 2419200, from: <from>, id: 1, status: done}}
you can use title and body which is added in data tag.
