问题描述
我目前正在使用 Math.floor(Date.now()/1000)
获取正确的时间戳格式以添加到 Firebase 中的文档中,但是,时间戳作为数字插入,而不是时间戳.
I'm currently using Math.floor(Date.now() / 1000)
to get the correct timestamp format to add into a document in Firebase, however, the timestamp gets inserted as a number, and not as a timestamp.
我希望将其插入如下所示(作为时间戳,而不是数字).
I would like to have it inserted as shown below (as a timestamp, not as a number).
这可能吗?
推荐答案
您可以简单地使用以下行:
You can simply use the following line:
var myTimestamp = firebase.firestore.Timestamp.fromDate(new Date());
.fromDate
是 Firebase 的 静态 Timestamp 类 中的 静态方法.
.fromDate
is a static method from the static Timestamp class from Firebase.

云功能看JGuo的评论:
For cloud functions look at JGuo's comment:
如果你正在编写云函数,它变成admin.firestore.Timestamp.fromDate()

If you are writing cloud functions, it becomes
admin.firestore.Timestamp.fromDate()
