使用Firebase云功能发送通知

为了使用Firebase Cloud Messaging稍后发送通知, 我正在尝试编写一个名为 sendNotification 的云函数; 我遇到了一个问题。如果可能的话,我想获得一些有关如何处理该问题的建议;或只是有人指出我可能正在做的错误。

这是运行命令时收到的错误消息:

firebase部署

⚠  functions[sendNotification(us-central1)]: Deployment error.
Function load error: Code in file index.js can't be loaded.
Did you list all required modules in the package.json dependencies?
Detailed stack trace: Error: Cannot find module 'serviceAccountKey.json'
    at Function.Module._resolveFilename (module.js:476:15)
    ........

serviceAccountKey.json 文件位于名为 node_modules 的目录中,换句话说,不要丢失。 这是index.js中的代码:

const functions = require('firebase-functions');
const admin = require('firebase-admin');
var serviceAccount = require('serviceAccountKey.json');

admin.initializeApp({
    credential: admin.credential.cert(serviceAccount),
    databaseURL: 'https://myapp.firebaseio.com'
});

exports.sendNotification = functions.https.onRequest((req, res) => {
    let registrationToken = "abc123.........789xyz";
    var payload = {
        notification: {
          title: "NotifTit",
          body: "The good stuff."
        },
        token: registrationToken
    };

    admin.messaging().send(payload)
    .then((response) => {
        console.log("Successfully sent message: ", response);
    })
    .catch((error) => {
        console.log("Error sending message: ", error);
    })
});

Here is the contents of the package.json file:

{
  "name": "functions",
  "description": "Cloud Functions for Firebase",
  "scripts": {
    "serve": "firebase serve --only functions",
    "shell": "firebase functions:shell",
    "start": "npm run shell",
    "deploy": "firebase deploy --only functions",
    "logs": "firebase functions:log"
  },
  "dependencies": {
    "firebase-admin": "~6.0.0",
    "firebase-functions": "^2.1.0"
  },
  "private": true
}

您无法从node_modules文件夹中加载文件,因为上载函数时该文件夹将被忽略。

但是要记住的一件事是整个node_modules文件夹   在上传源代码期间被忽略,因此您的package.json具有   包含所有依赖项,并且不能引用任何文件   在“ node_modules”内部。换句话说,您的功能仍应   如果您在   功能文件夹:

rm -rf node_modules 
npm install
