在Firebase的云功能上处理IPN [英] Handle IPN on Cloud Functions of Firebase

问题描述

在我的客户上，我有一个订单，其中包含我要购买的物品.当我结帐"订单时，我向Firebase云功能发送请求，该功能以指向在线支付交易的链接进行响应.客户完成交易后，来自公司(为其提供在线支付服务)的请求将分派给我的一个云部门，该部门将处理付款.

On my client, I have an order which has the items I want to buy. When I "checkout" the order, I send a request to my firebase cloud function and the function responds with a link to the online payment transaction. After the customer completes the transaction, a request from the company (who serves the online payment service) is being dispatched to one of my cloud functions who shall process the payment.

验证付款后，我想将付款的新数据存储到订单中(例如状态，完成日期等).

After I validate the payment, I want to store the new data of my payment to the order (e.g. status, completion date etc...).

如何存储我的新数据?我知道在Firestore中，我可以简单地使用.set(..)方法.

How can I store my new data? I know that with firestore I can simply use the .set(..) method.

推荐答案

我从评论中得到了答案(感谢Oleskii Miroshnyk).由于Oleskii并未将其发布为答案，所以我会的.

I've got my answer from the comments (Thanks to Oleskii Miroshnyk). Since Oleskii didn't post it as an Answer, then I will.

首先，我们需要导入firebase-admin:

import * as admin from 'firebase-admin';

或使用Javascript

or in Javascript:

const admin = require('firebase-admin');

在那之后，我们需要像这样初始化我们的应用程序:

After that, we need to initialize our application like so:

const serviceAccount = require('../service-account-key.json');

admin.initializeApp({
  credential: admin.credential.cert(serviceAccount),
  databaseURL: 'https://{PROJECT-ID}.firebaseio.com'
});

service-account-key.json可以在您的Firebase设置中找到.

The service-account-key.json can be found in your firebase settings.

完成配置后，就可以像这样访问firestore方法:

Once I finish with the configuration, I have access to the firestore method like so:

const firestore = admin.firestore();

firestore.collection(...).doc(...).set(...)

就是这样.其实很简单.

That's it. Quite simple actually.
