如何使用PayPal v2 orders API以编程方式批准订单

const paypal = require('@paypal/checkout-sdk');

// 初始化PayPal客户端
const clientId = 'YOUR_CLIENT_ID';
const clientSecret = 'YOUR_CLIENT_SECRET';
const environment = new paypal.core.SandboxEnvironment(clientId, clientSecret);
const client = new paypal.core.PayPalHttpClient(environment);

// 创建订单
const createOrder = async () => {
  const request = new paypal.orders.OrdersCreateRequest();
  request.prefer('return=representation');
  request.requestBody({
    intent: 'CAPTURE',
    purchase_units: [{
      amount: {
        currency_code: 'USD',
        value: '10.00'
      }
    }]
  });

  try {
    const response = await client.execute(request);
    const orderID = response.result.id;
    return orderID;
  } catch (error) {
    console.error(error);
    throw error;
  }
};

// 批准订单
const approveOrder = async (orderID) => {
  const request = new paypal.orders.OrdersAuthorizeRequest(orderID);
  
  try {
    const response = await client.execute(request);
    return response.result;
  } catch (error) {
    console.error(error);
    throw error;
  }
};

// 执行订单处理逻辑
const processOrder = async () => {
  try {
    const orderID = await createOrder();
    const approvalURL = await approveOrder(orderID);
    console.log('订单批准URL:', approvalURL);
  } catch (error) {
    console.error(error);
  }
};

processOrder();
