android - 将收据发送到电子邮件 android stripe

问题描述

我在我的 android 应用程序上使用 stripe 来收款。我希望能够在用户成功购买商品后向他们保存在数据库（Firebase）中的电子邮件发送收据。我确实查看了文档以了解如何去做，但我有点卡住了。我注意到我应该将此添加到我的服务器`receipt_email：'jenny.rosen@example.com'，但我只是想知道如何告诉它发送到从数据库（Firebase）保存的电子邮件。
//Server set up

const express = require("express");
const app = express();
const { resolve } = require("path");
// This is your real test secret API key.
const stripe = require("stripe")("sk_test_************************************************************");
app.use(express.static("."));
app.use(express.json());
const calculateOrderAmount = items => {
  // Replace this constant with a calculation of the order's amount
  // Calculate the order total on the server to prevent
  // people from directly manipulating the amount on the client
 console.log(items[0].amount)
 return items[0].amount;
};
app.post("/create-payment-intent", async (req, res) => {
  const { items } = req.body;
  const { currency } = req.body;
  // Create a PaymentIntent with the order amount and currency
  const paymentIntent = await stripe.paymentIntents.create({
    amount: calculateOrderAmount(items),
    currency: currency,
  receipt_email: 'jenny.rosen@example.com',

  });
  res.send({
    clientSecret: paymentIntent.client_secret
  });
});
app.get("/greet", async (req, res) => {
 res.send('Good to go');
});
const PORT= process.env.PORT || 5001;
app.listen(PORT, () => console.log('Node server listening on port $(PORT)'));
