问题描述
例如,我正在尝试从老师向学生发送推送通知.我正在使用Firebase,并且已经从每个设备上获取了该令牌,并将其保存在Firebase上并保存到所需的用户,然后设置了FirebaseMessagingService.现在,我希望能够以编程方式发送通知,例如,当老师单击列表中的学生时.我怎么做?我一直在寻找解决方案几天,却找不到答案.谢谢:)
I'm trying to send out a push notification from a teacher to a student, for example. I'm using firebase and I've already got that token from each device and saved it on firebase to the wanted user, and setup my FirebaseMessagingService.Now I want to be able to send a notification, programmatically, whenever a teacher clicks on a student in a list, for example.How do I do that? I've been looking for a solution for a couple of days and couldn't find an answer.Thanks :)
推荐答案
这就是我所做的.而且有效.我知道,因为我整夜都在努力使这件事起作用.
This is what I did. And it works. I know, because I was up all night trying to get this thing to work.
admin.messaging().sendToDevice(token, msg)
.then(resMsg => {
console.log("Successfully sent message", resMsg);
}).catch(err => {
console.log("Error sending message", err);
})
其中令牌是来自客户端设备的FCM令牌.而味精是具有以下结构的JSON负载:
Where token is the FCM token from the client device.And the msg is a JSON payload of the following structure:
const msg ={
notification: {
title: 'It\'s the last day of the week!',
body: `It's Sunday! Don't forget to refresh Dashboard with your latest activity data!`,
},
};
