javascript - 通过 NodeJS 将消息发布到 Firebase Cloud Messaging

Question

我正在尝试使用这个包实现一个简单的 Node js

https://www.npmjs.com/package/fcm-node

向我的 Firebase CM 发送 1 条简单的推送消息，以便它可以触发向 iPhone 发送推送通知

我已经执行了以下步骤，不知道为什么它仍然不起作用:

console.log("START");

var FCM = require('fcm-node')

var serverKey = require('/Users/john/Desktop/Apps/APNS/node/mhn-app-firebase-adminsdk-bs45c-5ac3770488.json') 

var fcm = new FCM(serverKey)

var message = { //this may vary according to the message type (single recipient, multicast, topic, et cetera)
    to: '##########',
    collapse_key: 'green',

    notification: {
        title: 'Title of your push notification',
        body: 'Body of your push notification'
    },

    data: {  //you can send only notification or only data(or include both)
        cpeMac: '000000000000',
        type: 'malware'
    }
}

fcm.send(message, function(err, response){
    if (err) {
        console.log("Something has gone wrong!")

        console.log(err);

    } else {
        console.log("Successfully sent with response: ", response)
    }
})

console.log("END");

结果

我不断陷入

console.log(err);

带有这些消息

⚡️  node  node app.js 
START
END
Something has gone wrong!
{ Error: Messaging payload contains an invalid "collapse_key" property. Valid properties are "data" and "notification".

  errorInfo:

     message: 'Messaging payload contains an invalid "collapse_key" property. Valid properties are "data" and "notification".' } }

我不知道该放什么作为collapse_key。如何在我的 Firebase 帐户中找到它？

Answer 1

您需要collapse_key: "new_message"和通知: { tag: "new_message"}

console.log("START");
var FCM = require('fcm-node');
var serverKey = require('secretKeyJson_path')
var fcm = new FCM(serverKey)
var collapseKey = 'new_message';
var message = {
    to: 'client_app_token',
    data: {
           cpeMac: '000000000000',
        type: 'malware' 
    },
    notification: {
        title: 'Hello motherfucker',
        body: 'Nice body',
        tag: collapseKey,
        icon: 'ic_notification',
        color: '#18d821',
        sound: 'default',
    },
};


fcm.send(message, function(err, response){
    if (err) {
        console.log("Something has gone wrong!")

        console.log(err);

    } else {
        console.log("Successfully sent with response: ", response)
    }
})

console.log("END");

仅针对您的上下文，collapse_key 旨在在设备离线时工作，并且当重新获得互联网连接时，它只会传递离线时收到的最后一个通知。
