.onCreate云函数触发后如何更新或设置Firestore文档的属性 [英] How to update or set property of firestore document after .onCreate cloud function trigger

问题描述

我目前正在尝试通过使用Cloud Functions for Firebase将Stripe与Firebase的Cloud Firestore数据库集成. onCreate 触发器正确发生，但我也希望它更新或设置一个名为"customer_id"的特定字段到我的Users集合中的正确文档中.我认为我的函数编写方式有些不完善，因为我对javascript的了解不是最丰富的.

I'm currently trying to integrate Stripe with my Firebase's Cloud Firestore db through using Cloud Functions for Firebase. The onCreate trigger is happening correctly but I also want it to update or set a specific field called "customer_id" into the right document in my Users collection. I think something is a little off about how I write my function since I'm not the most experienced with javascript.

我也尝试过

return admin.firestore().ref(`Users/${user.uid}/customer_id`).set(customer.id);

'use strict';

const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp();
//const logging = require('@google-cloud/logging')();
const stripe = require('stripe')(functions.config().stripe.token);
const currency = functions.config().stripe.currency || 'USD';

// When a user is created, register them with Stripe
exports.createStripeCustomer = functions.auth.user().onCreate((user) => {
    return stripe.customers.create({
      email: user.email,
    }).then((customer) => {
        return admin.firestore().collection("Users").doc(user.uid).update({"customer_id": customer.id})
    });
  });

使用Stripe创建客户没有问题，但是Firestore数据库上的"customter_id"字段未得到更新.

Customer gets created with Stripe no problem but the "customter_id" field is not getting updated on the Firestore db.
