Android 颤振-用户打开push notif消息(FCM)后如何执行任务
我有Android 颤振-用户打开push notif消息(FCM)后如何执行任务,android,firebase,flutter,dart,google-cloud-functions,Android,Firebase,Flutter,Dart,Google Cloud Functions,我有firebase云消息(FCM),可以向我的用户发送消息 但是,我想做一个场景,如果我的用户点击他们手机上的通知消息,那么应用程序将打开一个视图或弹出窗口,并执行一些后台任务 这可能吗 多谢各位 ==根据Shady Boshra的建议更新问题 1) 我使用typeScript创建谷歌云函数的firebase: import * as functions from 'firebase-functions'; import * as admin from 'firebase-admin'; ad
firebase云消息(FCM)
,可以向我的用户发送消息
但是,我想做一个场景,如果我的用户点击他们手机上的通知消息,那么应用程序将打开一个视图或弹出窗口,并执行一些后台任务
这可能吗
多谢各位
==根据Shady Boshra的建议更新问题
1) 我使用typeScript
创建谷歌云函数的firebase:
import * as functions from 'firebase-functions';
import * as admin from 'firebase-admin';
admin.initializeApp();
const fcm = admin.messaging();
export const sendNotif = functions.https.onRequest((request, response) => {
const tokens = request.query.tokens;
const payload: admin.messaging.MessagingPayload = {
notification: {
title: '[TEST-123] title...',
body: `[TEST-123] body of message... `,
click_action: 'FLUTTER_NOTIFICATION_CLICK',
tag: "news",
data: "{ picture: 'https://i.imgur.com/bY2bBGN.jpg', link: 'https://example.com' }"
}
};
const res = fcm.sendToDevice(tokens, payload);
response.send(res);
});
2) 我更新我的移动应用程序代码/Dart
:
_firebaseMessaging.configure(
onMessage: (Map<String, dynamic> message) {
print("::==>onMessage: $message");
message.forEach((k,v) => print("${k} - ${v}"));
String link = "https://example.com";
FlutterWebBrowser.openWebPage(url: link, androidToolbarColor: Pigment.fromString(UIData.primaryColor));
return null;
},
==更新3(对Shady Boshra回答的回应)
下面是我关于颤振的代码:
_firebaseMessaging.configure(
onMessage: (Map<String, dynamic> message) {
print("::==>onMessage: $message");
message.forEach((k,v) => print("${k} - ${v}"));
var data = message['notification']['data']['link'];
print ("===>data_notif = "+data.toString());
var data2 = message['data']['link'];
print ("===>data_notif2 = "+data2.toString());
...
\u firebaseMessaging.configure(
onMessage:(映射消息){
打印(“::==>onMessage:$message”);
message.forEach((k,v)=>print(${k}-${v}”);
var data=消息['notification']['data']['link'];
打印(“=>data_notif=“+data.toString());
var data2=消息['data']['link'];
打印(“=>data_notif2=“+data2.toString());
...
在发送push notif后,我在调试中刚刚收到以下消息:
The application is paused.
Reloaded 22 of 1277 libraries.

I/颤振(18608):数据-{}
申请完成。
如您所见,我无法获得
链接内部数据的值,是的,在本机中可以,但在flifter中我不确定。
你可以建造一个带有后堆叠的悬挂式帐篷
Intent notifIntent = new Intent(this, notifActivity.class);
TaskStackBuilder stkBuilder = TaskStackBuilder.create(this);
stkBuilder.addNextIntentWithParentStack(notifIntent);
PendingIntent resultPendingIntent =
stkBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
然后您应该将挂起的内容传递给通知
检查此链接:
当然,你也可以在颤振上做
首先,我希望您在清单中设置这些代码
在后端(node.js)的JSON通知正文中添加标记元素
const payload: admin.messaging.MessagingPayload = {
notification: {
title: 'New Puppy!',
body: `${puppy.name} is ready for adoption`,
icon: 'your-icon-url',
tag: 'puppy',
data: {"click_action": "FLUTTER_NOTIFICATION_CLICK", "id": "1", "status": "done"},
click_action: 'FLUTTER_NOTIFICATION_CLICK' // required only for onResume or onLaunch callbacks
}
};
在Dart代码中,确保在第一个initState()页面中设置此代码
•数据消息-包含键/值对形式的数据,并且
直接交付到应用程序而不触发通知
数据消息用于以静默方式向应用程序发送数据
例:
var payload = {
notification: {
title: "Account Deposit",
body: "A deposit to your savings account has just cleared."
}
};
var payload = {
data: {
account: "Savings",
balance: "$3020.25"
}
};
var payload = {
notification: {
title: "Account Deposit",
body: "A deposit to your savings account has just cleared."
},
data: {
account: "Savings",
balance: "$3020.25"
}
};
•组合消息–包含包含两个通知的有效负载
和数据。通知将显示给用户,并且数据
发送到应用程序
例:
var payload = {
notification: {
title: "Account Deposit",
body: "A deposit to your savings account has just cleared."
}
};
var payload = {
data: {
account: "Savings",
balance: "$3020.25"
}
};
var payload = {
notification: {
title: "Account Deposit",
body: "A deposit to your savings account has just cleared."
},
data: {
account: "Savings",
balance: "$3020.25"
}
};
因此,我认为您将使用第三个,它同时发送通知和数据
您可以使用dart访问数据,如下所示
message['data']['account']
更新2
当你更新你的问题时,我的解决方案没有很好地与你配合。我决定自己测试它,猜猜看!它与你的和相同的代码配合得很好
My node.js后端代码
'use strict';
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp();
const db = admin.firestore();
const fcm = admin.messaging();
exports.sendNotification = functions.firestore
.document('orders/{orderId}')
.onCreate(async snapshot => {
const order = snapshot.data();
// Token of my device only
const tokens = ["f5zebdRcsgg:APA91bGolg9-FiLlCd7I0LntNo1_7b3CS5EAJBINZqIpaz0LVZtLeGCvoYvfjQDhW0Qdt99jHHS5r5mXL5Up0kBt2M7rDmXQEqVl_gIpSQphbaL2NhULVv3ZkPXAY-oxX5ooJZ40TQ2-"];
const payload = {
notification: {
title: "Account Deposit",
body: "A deposit to your savings account has just cleared."
},
data: {
account: "Savings",
balance: "$3020.25",
link: "https://somelink.com"
}
};
return fcm.sendToDevice(tokens, payload);
});
和省道代码
final FirebaseMessaging _firebaseMessaging = FirebaseMessaging();
@override
void initState() {
super.initState();
_firebaseMessaging.requestNotificationPermissions();
_firebaseMessaging.configure(
onMessage: (Map<String, dynamic> message) async {
print("onMessage: $message");
var data2 = message['data']['link'];
print ("===>data_notif2 = "+data2.toString());
showDialog(
context: context,
builder: (context) => AlertDialog(
content: ListTile(
title: Text(message['notification']['title']),
subtitle: Text(message['notification']['body']),
),
actions: <Widget>[
FlatButton(
child: Text('Ok'),
onPressed: () => Navigator.of(context).pop(),
),
],
),
);
},
onLaunch: (Map<String, dynamic> message) async {
print("onLaunch: $message");
// TODO optional
},
onResume: (Map<String, dynamic> message) async {
print("onResume: $message");
// TODO optional
},
);
_saveDeviceToken();
}
/// Get the token, save it to the database for current user
_saveDeviceToken() async {
// Get the current user
String uid = 'jeffd23';
// FirebaseUser user = await _auth.currentUser();
// Get the token for this device
String fcmToken = await _firebaseMessaging.getToken();
// Save it to Firestore
if (fcmToken != null) {
print(fcmToken);
}
}
因此,我相信问题出在您的代码中,而不是我给您的解决方案中。请清楚地查找您可能遇到的问题。希望您能找到它并为您工作。最简单的方法是,如果您没有足够的时间构建后端以发送推送通知,那么如果使用firebase,OneSignal对n其订户(免费至30000订户).我尝试了您的解决方案,但仍然没有使用nodejs
而是使用firebase控制台。我收到了关于onMessage
状态的消息,但是对于onLaunch
和onResume
我无法在调试控制台上获得它。有什么想法吗?我更新了我的答案,请重新阅读,但您将无法继续使用firebase co仅限NSLE,然后应继续使用后端node.js作为示例。我的Android清单上已有flatter\u NOTIFICATION\u CLICK
intent。但它不起作用…现在可以解决了,因为我以前的代码(firebase)正在使用typeScript
而不是javascript
哦,我明白了。祝你完美的时间编码。尝试删除双qoutes,看看它是否有效,数据:{picture:'https://i.imgur.com/bY2bBGN.jpg'链接:'https://example.com“}
@ShadyBoshra如果我这样做,它会返回错误,请参阅更新的问题(更新2)…试试这个数据:{'picture':'https://i.imgur.com/bY2bBGN.jpg'链接':'https://example.com“}
我在keystil错误前后添加了单个qoute:类型“{'picture':string;'link':string;}”不能分配给类型“string”。
@ShadyBoshra对不起,还没有。我明天再看。谢谢。。。。
