如何在Node.js中更新Stripe paymentIntent？

如何解决如何在Node.js中更新Stripe paymentIntent？

我正在为非营利组织构建捐赠表格，并且正在努力更新发送到我的Node.js Stripe后端的更新付款金额。

前端是React，我正在使用useEffect（）钩子创建我的paymentIntent。看来，使用新的Stripe API，返回clientSecret所需的金额。否则，我想在用户选择捐赠金额之后创建paymentIntent（就像我对类似实现所做的那样）。

我正在使用方法“ stripe.paymentIntents.update（）”来更新金额。这显示在console.log中已更新，但未更新发送到Stripe的paymentIntent。

我该如何更新要发送的PaymentIntent以确认ConfirmCardPayment（）？

server.js

  app.post("/create-payment-intent",async (req,res) => {
  let amount = req.body.amount;
  const name = req.body.name;
  
  const options = {
    description: 'Teton Valley Aquatics Donation',amount,currency: "USD",name: name,};

  console.log(req.body.amount) //returns my default amount {1000}

  try {
    const paymentIntent = await stripe.paymentIntents.create(options);
    res.json(paymentIntent);
  }
   catch (err) {
    res.json(err);
  }

app.post("/create-payment-intent/update-amount",res) => {
  const amount = req.body;
  console.log(req.body) //returns {amount: 25}
  try {
    const paymentIntent = await stripe.paymentIntents.update(amount,{
      amount,});
    console.log(`Updated amount: ${amount}`);
    res.json(paymentIntent);
  }
  catch (err) {
    res.json(err)
  }
})
});

CheckoutForm.jsx

useEffect(() => {
api
.createPaymentIntent({
  amount
})
.then((clientSecret) => {
  setClientSecret(clientSecret);
})
.catch((err) => {
  setError(err.message);
});

console.log(`Amount: ${amount}`)
},[]);


  const handleSubmit = async (ev) => {
    ev.preventDefault();
    setProcessing(true);
    
    api
      .updatePaymentIntent({
        amount,})
      .catch((err) => {
        setError(err.message);
      });

    const payload = await stripe.confirmCardPayment(clientSecret,{
      payment_method: {
        card: elements.getElement(CardElement),billing_details: {
          name: ev.target.name.value,email: ev.target.email.value
        },},});

    if (payload.error) {
      setError(`Payment failed: ${payload.error.message}`);
      setProcessing(false);
      console.log("[error]",payload.error);
    } else {
      setError(null);
      setSucceeded(true);
      setProcessing(false);
      setMetadata(payload.paymentIntent);
      console.log("[PaymentIntent]",payload.paymentIntent);
    }
  };

api函数

const createPaymentIntent = options => {
  return window
    .fetch(`http://localhost:4242/create-payment-intent`,{
      method: "POST",headers: {
        "Content-Type": "application/json"
      },body: JSON.stringify(options)
    })
    .then(res => {
      if (res.status === 200) {
        return res.json();
      } else {
        return null;
      }
    })
    .then(data => {
      if (!data || data.error) {
        console.log("API error:",{ data });
        throw new Error("PaymentIntent API Error");
      } else {
        return data.client_secret;
      }
    });
};

const updatePaymentIntent = options => {
  return window
    .fetch(`http://localhost:4242/create-payment-intent/update-amount`,{ data });
        throw new Error("PaymentIntent API Error");
      } else {
        return data.client_secret;
      }
    });
}

解决方法

update的第一个参数应该是付款意向ID。看来您有错别字/错误，将amount放入了两次：

const paymentIntent = await stripe.paymentIntents.update(**amount**,{
  amount,});

应为：

const paymentIntent = await stripe.paymentIntents.update(**paymentIntentId**,});
