node.js中的Firebase不工作

Question

我在node中实现firebase时遇到了一些问题。下面是我试图在节点上运行的代码。

var firebase = require("firebase");
var admin = require("firebase-admin");

var serviceAccount = require("./service_account.json");

admin.initializeApp({
     credential: admin.credential.cert(serviceAccount),
     databaseURL: "https://<myfirebasedb>.firebaseio.com/"
});

var Queue = require('firebase-queue')

firebase.initializeApp({
    databaseURL: "https://<myfirebasedb>.firebaseio.com/"
});

//start your worker here. "users" is a table in my db which has users.
var ref = firebase.database().ref('users');
var queue = new Queue(ref, function(data, progress, resolve, reject) {
  // Read and process task data
  console.log(" Inside I am!! ")
  console.log(data);

  // Do some work
  progress(50);

  // Finish the task asynchronously
  setTimeout(function() {
    resolve();
  }, 1000);
});

console.log(" hello world ")

看起来我的代码从来没有运行过。它只打印最后一行的"hello world“。

代码永远不会运行的原因是，firebase的Cloud functions会处理由Firebase功能或HTTPS请求触发的事件。你的代码只是停留在那里，永远不会被调用。

查看firebase文档，特别是关于“编写函数”的部分
