節點和Firebase雲消息傳遞類型錯誤

Question

繼續收到TypeError，我無法弄清楚原因。我使用（npm install firebase --save）安裝了Firebase。這是我的代碼：

var firebase = require("firebase"); // Firebase 
var express = require('express'); // Express instaniated a different way for serving static webpages 
var app = express(); // Express App include 

    // Set port 
    app.listen(8085); 

    // Initialize Firebase 
     var config = { 
      apiKey: "AIza...............", 
      authDomain: ".....firebaseapp.com", 
      databaseURL: "...............", 
      storageBucket: "..........appspot.com", 
      messagingSenderId: "..............." 
     }; 
     firebase.initializeApp(config); 

    // Create the URL for using Firebase 
    app.get('/fcmtest', function (req, res) { 

     const messaging = firebase.messaging(); 
     messaging.requestPermission() 
      .then(function() { 
       console.log("Have Permission") 
      }) 
      .catch(function (err) { 
       console.log("Do Not Have Permission"); 
      }); 
    }); 

這是我收到的錯誤。 InitializeApp似乎工作正常，但消息不起作用。 （npm -v firebase）吐出3.10，但npm網頁上說最新的是3.6.1。

任何幫助，非常感謝。

看完這個： https://www.npmjs.com/package/firebase

「沒有包含服務器端火力地堡NPM模塊火力地堡雲消息相反，你可以使用火力地堡雲端通訊REST API」

因此，您應該對其他消息進行其他調用，但是您不能在代碼中使用消息傳遞函數。

見REST API文檔： https://firebase.google.com/docs/cloud-messaging/send-message#http_post_request
