如何在本地主机中使用 Stripe webhooks？

Question

我是第一次尝试使用 Stripe webhooks。以下是调用“/webhook”端点时返回的响应👇🏻

{
    "type": "StripeSignatureVerificationError",
    "raw": {
        "message": "No stripe-signature header value was provided."
    },
    "payload": {}
}

我已阅读并遵循 Stripe 官方文档中概述的步骤，但是，它似乎无法正常工作，而且我不明白我所缺少的内容。

// stripe.service.ts

import config from 'config';
import Stripe from 'stripe';

const stripeSecretKey = config.get<string>('stripeSecretKey');

export const stripe = new Stripe(stripeSecretKey, {
  apiVersion: '2023-10-16',
  typescript: true,
});

// webhook.controller.ts 

import config from 'config';

import { Request, Response, NextFunction } from 'express';

import { stripe } from '@/services/stripe.service';

const stripeWebhookSigningSecret = config.get<string>('stripeWebhookSigningSecret');

export const webhookController = async (
  req: Request,
  res: Response,
  next: NextFunction
) => {
  const payload = req.body;
  const sig = req.headers['stripe-signature'] as string;

  let event;

  try {
    event = stripe.webhooks.constructEvent(
      payload,
      sig,
      stripeWebhookSigningSecret
    );
  } catch (error) {
    return res.status(400).send(error);
  }
  console.log(event.type);
  console.log(event.data.object);
  return res.json({ received: true });
};

// routes.ts

  app.post(
'/webhook',
bodyParser.raw({ type: 'application/json' }),
webhookController
  );

以下是我在 CLI 中遵循的流程👇🏻

- npm run dev
> API is running on http://localhost:3000.

- stripe login

- stripe listen --forward-to localhost:3000/webhook
> Ready! You are using Stripe API Version [2022-11-15]. Your webhook signing secret is whsec_xxx

2023-10-26 23:43:26   --> charge.succeeded [evt_xxx]
2023-10-26 23:43:26  <--  [400] POST http://localhost:3000/webhook [evt_xxx]
2023-10-26 23:43:26   --> payment_intent.succeeded [evt_xxx]
2023-10-26 23:43:26  <--  [400] POST http://localhost:3000/webhook [evt_xxx]
2023-10-26 23:43:26   --> payment_intent.created [evt_xxx]
2023-10-26 23:43:26  <--  [400] POST http://localhost:3000/webhook [evt_xxx]

- stripe trigger payment_intent.succeeded
> Setting up fixture for: payment_intent
  Running fixture for: payment_intent
  Trigger succeeded! Check dashboard for event details.

我没有从 Stripe webhooks 收到任何数据。我缺少什么？非常感谢！

Answer 1

我终于在这里找到了问题的解决方案：Stripe - Webhook 负载必须以字符串或缓冲区的形式提供

实际上，中间件

app.use(express.json());

必须放在端点之后。事实上，Express 将 Stripe 的签名解释为一个对象。我在我的

createServer.ts

👇🏻

设定了一个条件

  // Body parser.
  app.use((req, res, next) => {
    req.path !== '/webhook' ? express.json()(req, res, next) : next();
  });

这样它不适用于

/webhook

端点。
