无法将商品和价格传递到 stripe checkout

Question

我正在为我的自定义电子商务网站使用嵌入式 nodejs/javascript Stripe Checkout。我有自己的使用 DB2 创建的购物车，我想传递客户在购物车中的产品名称，以及每个产品的匹配价格。 Stripe 不是很清楚如何做到这一点，我一直在努力寻找正确的方法。我现在正在尝试使用 2 个数组（产品数组和价格数组）并试图将它们传递给 Stripe 函数，但没有成功。这是代码。

app.post('/create-checkout-session', (req, res) => {

var amount = stringify(req.body)
console.log(req.body.sessionID)
var userId = req.body.sessionID
console.log("email: " + req.body.customer_email)
var email = req.body.customer_email;
var deliveryTotal = req.body.totalWithDelivery;
var totalVal = amount.split("=");
var totalPrice = parseFloat(totalVal[1]);
//console.log("TOTAL PRICE: " + totalPrice);
var finalPrice = parseFloat(Math.round(totalPrice * 100) / 100);

var finalTotal = parseFloat(Math.round(totalPrice * 100) / 100) + parseFloat(Math.round(deliveryTotal));
console.log("final total: " + finalTotal);
var itemName = ""
var itemPrice = ""
var totalNewPriceTest = ""

//defining arrays
var productsArray = [];
var priceArray = [];
//query to database

var productsStripe = "select * from " + userId
console.log(userId)
console.log("query to db for displaying cart on stripe page")
ibmdb.open("DATABASE=BLUDB;HOSTNAME=dashdb-txn-sbox-yp-dal09-14.services.dal.bluemix.net;PORT=50000;PROTOCOL=TCPIP;UID=;PWD=", function (err,conn) {
    if (err) return console.log(err);
  conn.query(productsStripe,  async function (err, rows) {
    if (err) {
      console.log(err)
    }
    console.log(rows)
    for(var i = 0; i < rows.length; i++) {
    //   itemName = rows[i]['ITEM']
    //   itemPrice = rows[i]['PRICE']
      totalNewPriceTest = parseFloat(rows[i]['PRICE'])
      console.log("item name : " + itemName + " " + itemPrice )
      totalNewPriceTest = parseFloat(totalNewPriceTest);
      console.log("final overall prcie: " + (totalNewPriceTest))

    //inserting items and prices into arrays
     productsArray.push(rows[i]['ITEM'])
     priceArray.push(rows[i]['PRICE'])
     console.log("ARRAY " + productsArray)
     console.log("PRICE ARRAY " + priceArray)
    }
    console.log("inside productsStripe function.")
    console.log("overall prcie: " + totalNewPriceTest)

    totalNewPriceTest = parseFloat(totalNewPriceTest)
    var grandTotal = totalNewPriceTest;
    var finalGrandTotal = parseFloat(grandTotal)
    console.log(parseFloat(finalGrandTotal))

  
    //stripe
    const session = await stripe.checkout.sessions.create({
      shipping_address_collection: {
        allowed_countries: ['CA'],
      },

      payment_method_types: ['card'],
      line_items: [
        {
          price_data: {
            currency: 'CAD',
            product_data: {
              name: stringify(productsArray),
            },
            unit_amount: parseFloat(priceArray),
            //finalTotal * 100
          },
          quantity: 1,
        },
      ],

      mode: 'payment',
      success_url: 'https://floralfashionboutique.com/successPg',
      cancel_url: 'https://floralfashionboutique.com/catalogue',
      customer_email: email,
    });
    // console.log(session)
    res.json({ id: session.id });
    //console.log("customer id" + customer.id)
    console.log("totalNewPriceTest " + totalNewPriceTest)

  })
})

});

请让我知道以前是否有人尝试过这样做，网上没有太多关于它的信息......另外，对于混乱的代码感到抱歉......

这里有几件事：

product_data 是您想要动态创建产品 in-line 时使用的方法。通常您会事先在仪表板上创建这些。如果您仍然需要动态创建这些，您应该遵循此处描述的对象形状：https://stripe.com/docs/api/checkout/sessions/create?lang=node#create_checkout_session-line_items-price_data-product_data
unit_amount 需要是一个整数。 parseFloat(priceArray) 将解析 priceArray 的第一个值并忽略其余值，这可能不是您在此处尝试做的
如果您尝试创建多个价格，每个价格都有自己的产品和 unit_amount，那么您需要在 line_items 中为每个创建一个条目。像这样：

// loop over your products array to construct the line_items
const items = productsArray.map((product, i) => {
  return {
    price_data: {
      currency: 'CAD',
      product_data: {
        name: product,
      },
      unit_amount: parseInt(priceArray[i], 10),
    },
    quantity: 1,
  };
});

const session = await stripe.checkout.sessions.create({
  shipping_address_collection: {
    allowed_countries: ['CA'],
  },
  payment_method_types: ['card'],
  line_items: items,
  mode: 'payment',
  success_url: 'https://floralfashionboutique.com/successPg',
  cancel_url: 'https://floralfashionboutique.com/catalogue',
  customer_email: email,
});
