Cloud Functions中的Cloud Messaging:admin.messagin(...).send不是函数 [英] Cloud Messaging in Cloud Functions: admin.messagin(...).send is not a function
问题描述
我的功能由数据库事件触发,并使用Firebase Cloud Messaging向主题发送通知.我的第一个函数运行正常,但是第二个函数不断抛出此错误:
My function is triggered by a database event and uses Firebase Cloud Messaging to send a notification to a topic. My first function works fine, but the second one keeps throwing this error:
2018-02-20T21:16:49.878Z E receiveMessage: TypeError: admin.messaging(...).send is not a function
at exports.receiveMessage.functions.database.ref.onCreate (/user_code/index.js:55:27)

这是index.js文件:
here is the index.js file:
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);
// // Create and Deploy Your First Cloud Functions
// // https://firebase.google.com/docs/functions/write-firebase-functions
//
// exports.helloWorld = functions.https.onRequest((request, response) => {
// response.send("Hello from Firebase!");
// });
exports.recceiveInvitation = /* the function that works */;
exports.receiveMessage = functions.database.ref('/messages/{chatId}/{time}').onCreate((event) => {
const chatId = event.params.chatId;
console.log('messages', chatId);
var sender = event.data.val().name;
var messageContent = event.data.val().message;
if(messageContent.length >= 100){
messageContent = messageContent.substring(0,97)+"...";
}
const payload = {
data: {
title: `New Message from ${sender}`,
body: messageContent
},
topic: chatId
};
return admin.messaging().send(payload);
});
我运行了npm install firebase-admin,但没有帮助.
I ran npm install firebase-admin, but I did not help.
推荐答案
更改此内容:
return admin.messaging().send(payload);
对此:
return admin.messaging().sendToTopic(topicname,payload);
能够发送主题通知.
您可以执行上述操作,或查看以下注释
您需要更新firebase-admin
npm软件包,才能使用send()
:
You need to update the firebase-admin
npm package, to be able to use send()
:
npm install firebase-admin@latest
