我如何知道哪个用户在stripe中进行了支付

Question

我正在整合条纹与我的应用程序。我想从一个登录的用户收到一次付款，一旦付款完成可能保存在数据库中的支付状态。

我已经设置了条带检出和条带webhook。但是，我如何知道哪个登录用户从客户端进行了支付，以便我可以设置该用户在数据库中的支付状态。

这是我的结帐和webhook的样子

app.post("/checkout-session", async (req, res) => {
try {
const session = await stripe.checkout.sessions.create({
payment_method_types: ["card"],
mode: "payment",
line_items: req.body.items.map((item) => {
const storeItem = storeItems.get(item.id);
return {
price_data: {
currency: "usd",
product_data: {
name: storeItem.name,
},
unit_amount: storeItem.priceInCents,
},
quantity: item.quantity,
};
}),
success_url: `${process.env.CLIENT_URL}/success`,
cancel_url: `${process.env.CLIENT_URL}/failure`,
});
res.json({ url: session.url });
} catch (e) {
res.status(500).json({ error: e.message });
}
});
app.post("/webhook", express.raw({ type: "application/json" }), (req, res) => {
let event;
// Only verify the event if you have an endpoint secret defined.
// Otherwise use the basic event deserialized with JSON.parse
if (process.env.STRIPE_WEBHOOK_SECRET) {
// Get the signature sent by Stripe
const signature = req.headers["stripe-signature"];
try {
event = stripe.webhooks.constructEvent(
req.body,
signature,
process.env.STRIPE_WEBHOOK_SECRET
);
} catch (err) {
console.log(`⚠️  Webhook signature verification failed.`, err.message);
return res.sendStatus(400);
}
}
// Handle the event
switch (event.type) {
case "payment_intent.succeeded":
const paymentIntent = event.data.object;
console.log(`PaymentIntent for ${paymentIntent.amount} was successful!`);
console.log(paymentIntent);
// Then define and call a methstripe loginod to handle the successful payment intent.
// handlePaymentIntentSucceeded(paymentIntent);
break;
case "payment_method.attached":
const paymentMethod = event.data.object;
// Then define and call a method to handle the successful attachment of a PaymentMethod.
// handlePaymentMethodAttached(paymentMethod);
break;
case "payment_intent.payment_failed":
const failedpaymentIntent = event.data.object;
console.log(`PaymentIntent for ${paymentIntent.amount} failed!`);
// Then define and call a methstripe loginod to handle the successful payment intent.
// handlePaymentIntentSucceeded(paymentIntent);
break;
case "checkout.session.completed":
console.log(event.data.object);
// console.log(`PaymentIntent for ${paymentIntent.amount} failed!`);
// Then define and call a methstripe loginod to handle the successful payment intent.
// handlePaymentIntentSucceeded(paymentIntent);
break;
default:
// Unexpected event type
console.log(`Unhandled event type ${event.type}.`);
}
// Return a 200 response to acknowledge receipt of the event
res.send();
});``` 

Answer 1

在checkout.session.completed事件中，您将能够在Checkout Session对象中找到customer_details.email以识别客户。

或者，您的内部客户ID可以在结帐会话创建API的metadata参数下设置。在支付成功后，元数据将出现在checkout.session.completed中，您可以使用它来更新数据库中的支付状态。

Answer 2

在登录时，您可以使用json web token (jwt)以加密格式发送登录的用户对象，并使用local storage存储该令牌。并与请求一起，将此令牌发送到后端并解码。你将从中获得用户对象，然后你可以找到哪个用户正在发送请求。
