如何从Firebase云功能访问firestore.Timestamp

我们正在将Firestore Date对象转换为新的Timestamp Objects

我们通过导入firestore在前端成功完成了

import { firestore } from 'firebase';

然后用firestore.Timestamp替换所有Date对象类型

  startDate: firestore.Timestamp;

问题是我似乎无法找到一种方法来访问节点中的Timestamp。

我已经尝试记录管理员和函数对象，但似乎根本找不到时间戳

import * as functions from 'firebase-functions';
import * as admin from 'firebase-admin';
...
console.log(functions)
console.log(admin)

这些是我尝试过的，他们都返回'时间戳不存在于未定义'

import * as firebase from 'firebase';
...
firebase.firestore.Timestamp.now()

const firebase = require('firebase')   
...
firebase.firestore.Timestamp.now()

import * as admin from 'firebase-admin';
...
admin.firestore.Timestamp.now()

这是我的package.json依赖项

    "webpack-node-externals": "^1.7.2"
}

随着Firebase功能V2.0的发布，他们看起来已经在Firebase Admin SDK包中添加了Timestamp支持。

看看官方文档here。

import { firestore } from 'firebase-admin';
...
const now = firestore.Timestamp.now()
