400 使用 PayPal v2 createOrder 时出现错误请求错误

Question

这是前端代码：

const createOrder = () => {
// Order is created on the server and the order id is returned

return fetch(`${serverUrl}/api/orders`, {
  method: "POST",
   headers: {
    "Content-Type": "application/json"
  },

  // use the "body" param to optionally pass additional order information

  // like product skus and quantities

  body: JSON.stringify({
    cart: [
      {
        id:'woodcandysofa',
        name:'Wood Candy Sofa',
        quantity: 1,
        price: 399
      },
    ],
  }),
})

.then((response) => response.json())
.then((order) => order.id);

};

这是后端：

module.exports.createOrder = async (cart) => {
    // use the cart information passed from the front-end to calculate the purchase unit details
    console.log(
      "shopping cart information passed from the frontend createOrder() callback:",
      cart,
    );
      const totalPrice = cart.reduce ((prev, curr) => prev + curr.price, 0);
    const accessToken = await generateAccessToken();
    const url = `${base}/v2/checkout/orders`;
    const payload = {
      intent: "CAPTURE",
      purchase_units: [
        {
          amount: {
            currency_code: "EUR",
            breakdown: {
              item_total: totalPrice
            },
            value: totalPrice
          },
          items: cart.map (item => ({
            name: item.name,
            quantity: item.quantity,
            unit_amount: { currency_code: 'EUR', value: item.price * item.quantity}
          }))
        },
      ],
    }

这是我在后端收到的错误：

_Response [Response] { [Symbol(realm)]: null, [Symbol(state)]: { aborted: false, rangeRequested: false, timingAllowPassed: true, requestIncludesCredentials: true, type: 'default', status: 400, timingInfo: { startTime: 11720.420841999352, redirectStartTime: 0, redirectEndTime: 0, postRedirectStartTime: 11720.420841999352, finalServiceWorkerStartTime: 0, finalNetworkResponseStartTime: 0, finalNetworkRequestStartTime: 0, endTime: 0, encodedBodySize: 0, decodedBodySize: 0, finalConnectionTimingInfo: null }, cacheState: '', statusText: 'Bad Request', 

如果我不传递任何项目而只传递金额（货币代码和值），那么它就可以正常工作。但我需要有关到底购买了什么的信息。

有什么想法吗？感谢您的阅读。

尝试集成 PayPal v2 并提供 items 数组。没有 items 数组，它可以工作 - 有了它，它就会失败。

Answer 1

这是崩溃。正确的语法是：

breakdown: {
          item_total: {value: totalPrice, currency_code:'EUR'}
        }
