Question

我有一个使用firebase作为后端的Android应用程序。

一旦数据库在特定节点发生变化，使用 firebase云功能，通知就会触发。

但我无法弄清楚如何根据特定节点的变化打开特定活动。

我在数据库中有5个活动和5个节点，应该通过通知打开的活动应该是与特定节点上的更改相对应的活动。

但是现在它会打开默认活动。

我无法确定通知如何包含在其有效负载中打开特定活动的信息，因为通知是通过firebase云功能提供的。

index.js的示例文件粘贴在下面，仅用于一个子节点的更改。

'use strict';

const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);


exports.sendPowerNotification = functions.database.ref("/Matrimony").onWrite((event) => {
    const data = event.data;
    console.log('New Issue added');
    if (!data.changed()) {
        return;
    }
    const status = data.val();
    //const onOff =  status ? "on": "off";
    const author = event.params.author;
        const name = author.val();

    const payload = {
        notification: {
            title: 'SahuSmaj : New Matrimony Post',
            body: `New biodata entered,check it out`,
            sound: "default"
            click_action: "MATRIMONY"
        }
    };

    const options = {
        priority: "high",
        timeToLive: 60 * 60 * 24 //24 hours
    };
    console.log('Sending notifications');
    return admin.messaging().sendToTopic("matrimony", payload, options);

});

执行上面的代码会显示以下错误：

我已在 AndroidManifest.xml 中进行了更改，以使用 Android过滤器打开特定通知。

        <intent-filter>
            <action android:name="MATRIMONY" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>

sound: "default"

应该是：

const payload = {
        notification: {
            title: 'SahuSmaj : New Matrimony Post',
            body: `New biodata entered,check it out`,
            sound: "default"
            click_action: "MATRIMONY"
        }
    };
