问题描述

我想使用Firebase来获取服务器上的当前时间，而无需写入数据库然后再读取它.

I want to use Firebase to get the current time on server without writing to the database and then reading it.

有人知道直接从Firebase获取当前时间戳的解决方案吗?

Any one knows a solution to directly get a current time stamp from Firebase?

推荐答案

是的！无论是针对IOS还是Android，都可以在 Firebase的云函数中编写函数就像:

Yes there is! It doesn't matter if it is for IOS or for Android, you can write a frunction in Cloud Functions for Firebase which will be as easy as:

exports.currentTime = functions.https.onRequest((req, res) => {
    res.send({"timestamp":new Date().getTime()})
})

您可以将其托管在Cloud Function中，无需用户干预即可获取服务器时间戳.

You can host this in Cloud Function and get the server timestamp without user interaction.
