推荐答案

看看Cloud Functions.他们将完全满足您的需求.

Take a look at Cloud Functions. They will do exactly what you need for this.

您需要设置和理解Firebase的一些内容，因此，先阅读一下有关Firebase的基本教程也是一个不错的计划.

There's a few pieces you'll need to setup and understand about firebase, so checking out a basic tutorial on that first would be a good plan too.

我最近做了一个会议，在会议上我们在舞台上构建了一个应用程序，而Cloud Function将我们的设备遥测技术带入了Firestore(不是Firebase RTD，而是在更新的软件包中具有相同的概念):

I did a session recently where we built an application on stage, and the Cloud Function that brought our device telemetry over into Firestore (not Firebase RTD, but same concepts in an updated package):

这是Cloud Function本身的代码.要了解您正在查看的作品周围的概念，请查看:

That's the code for the Cloud Function itself. To understand the concepts around the pieces you're looking at, check out:
