如何从Firebase云功能访问firestore.Timestamp

Question

我们正在将Firestore Date对象转换为新的Timestamp对象

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 dependancies

    "@sendgrid/mail": "^6.2.1",

Answer 1

随着Firebase Functions V2.0的发布，他们似乎已经在Firebase Admin SDK软件包中添加了Timestamp支持。

在这里看看官方文档。

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

Answer 2

在这个时刻,Timestamp在@google-cloud/firestore节点的npm模块的最新版本中根本不可用.您还可以看到它未包含在API文档中.也许它将在下一版本中添加@google-cloud/firestore.
