如何在Firebase Cloud Firestore中收听实时更新? [英] How to listen for realtime updates in Firebase Cloud Firestore?

问题描述

在Firebase的官方文档中，我们可以使用 https://firebase.google.com/docs/firestore/query-data/listen

In the official documentation of Firebase, we can do it with https://firebase.google.com/docs/firestore/query-data/listen

let doc = db.collection('cities').doc('SF');

let observer = doc.onSnapshot(docSnapshot => {
  console.log(`Received doc snapshot: ${docSnapshot}`);
  // ...
}, err => {
  console.log(`Encountered error: ${err}`);
});

但是我们如何使用Google Apps脚本呢?

But how can we do it with Google Apps Script?

推荐答案

在事件(如数据更新)上运行Apps脚本意味着要使用触发器.不幸的是，目前还没有 Apps脚本触发器支持Firebase.

To run an Apps Script on a event (like a data update) implies using triggers. Unfortunately, at the moment there are no Apps Script triggers supporting Firebase.

但是，您可以在随附的 HTML 文件中包含JavaScript代码到您的Apps脚本文件，并将其部署为网络应用.

However, you can include JavaScript code in the HTML file attached to your Apps Script file and deploy it as a Web App.
