将日期转换为时间戳，以便在 javascript 中存储到 firebase firestore

2022-01-13 00:00:00 firebase timestamp date google-cloud-firestore javascript

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() – JGuo 1 月 21 日 1:56

If you are writing cloud functions, it becomes admin.firestore.Timestamp.fromDate() – JGuo Jan 21 at 1:56
