我尝试在Stripe webhook端点中验证请求签名，但一直收到错误：

No signatures found matching the expected signature for payload. Are you passing the raw request body you received from Stripe?

我已经尝试了多种解决方案，多种解析原始请求体的方法。我也试过手动验证HMAC信号。什么都没用。
我的环境：
Next.js 13.3.2 Stripe SDK 12.4.0
复制步骤：
1.在以下位置创建端点：/pages/api/p/test
代码：

import Stripe from 'stripe';
import { NextApiRequest, NextApiResponse } from 'next';
import safe from 'colors/safe';
import { buffer } from 'micro';

const handler = async (
    req: NextApiRequest,
    res: NextApiResponse
): Promise<void> => {
    const stripe = new Stripe(process.env.STRIPE_SECRET as string, {
        apiVersion: '2022-11-15',
    });

    const webhookSecret: string = "whsec_33244....";

    if (req.method === 'POST') {
        const sig = req.headers['stripe-signature'] as string;
        const buf = await buffer(req);
        const body = buf.toString();

        let event: Stripe.Event;

        try {
            console.log(safe.bgGreen(body))
            event = stripe.webhooks.constructEvent(body, sig, webhookSecret);
        } catch (err) {
            // On error, log and return the error message
            console.log(`❌ Error message: ${err.message}`);
            res.status(400).send(`Webhook Error: ${err.message}`);
            return;
        }

        // Successfully constructed event
        console.log('✅ Success:', event.id);

        // Cast event data to Stripe object
        if (event.type === 'payment_intent.succeeded') {
            const stripeObject: Stripe.PaymentIntent = event.data
                .object as Stripe.PaymentIntent;
            console.log(`💰 PaymentIntent status: ${stripeObject.status}`);
        } else if (event.type === 'charge.succeeded') {
            const charge = event.data.object as Stripe.Charge;
            console.log(`💵 Charge id: ${charge.id}`);
        } else {
            console.warn(`🤷‍♀️ Unhandled event type: ${event.type}`);
        }

        // Return a response to acknowledge receipt of the event
        res.json({ received: true });
    } else {
        res.setHeader('Allow', 'POST');
        res.status(405).end('Method Not Allowed');
    }
};

export const config = {
    api: {
        bodyParser: false,
    },
};

export default handler;

1.启动dev服务器并启动条带侦听器

stripe listen --forward-to localhost:3000/api/p/test

1.复制生成的webhook签名密钥并粘贴到代码中
1.启动模拟事件

stripe trigger payment_intent.succeeded

我在网上搜遍了所有的方法。我完全被难倒了。我正在使用微服务包中的buffer，但我也在Stripe的文档中尝试了示例中的缓冲区功能。它似乎正确地解析了主体：

console.log(body)
