通过NodeJS向Firebase Cloud Messaging发送POST消息

Question

我正在尝试使用这个包实现一个简单的节点js

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

向我的Firebase CM发送一条简单的推送消息，这样它就可以触发对iPhone 的推送通知

我已经完成了以下步骤，不确定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

我一直陷入

console.log(err);

这些信息

⚡️  node  node app.js 
START
END
Something has gone wrong!

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

Answer 1

您需要collapse_key:"new_message"和notification:｛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");

仅就您的上下文而言，collapsekey用于在设备脱机时工作，而当重新获得互联网连接时，它只会传递脱机时收到的最后一个通知。
