节点和 Firebase 云消息传递类型错误

Question

不断收到 TypeError，我不知道为什么。我使用 (npm install firebase --save) 安装了 Firebase。这是我的代码：

    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");
            });
    });

这是我收到的错误。 InitializeApp 似乎工作正常，但消息传递不起作用。 (npm -v firebase) 吐出 3.10，但 npm 网页显示最新的是 3.6.1。

非常感谢任何帮助。

读完后： https://www.npmjs.com/package/firebase

“Firebase Cloud Messaging 不包含在服务器端 Firebase npm 模块中。相反，您可以使用 Firebase Cloud Messaging Rest API。”

所以你应该为消息传递休息调用，但你不能像你尝试的那样在代码中使用消息传递功能。

请参阅 REST API 文档： https://firebase.google.com/docs/cloud-messaging/send-message#http_post_request
