双十一聚合支付购买

// 引入支付SDK
const WechatPay = require('wechatpay-sdk');
const Alipay = require('alipay-sdk');

// 初始化支付实例
const wechatPayInstance = new WechatPay({
  appId: 'your_wechat_app_id',
  mchId: 'your_wechat_merchant_id',
  apiKey: 'your_wechat_api_key'
});

const alipayInstance = new Alipay({
  appId: 'your_alipay_app_id',
  privateKey: 'your_alipay_private_key',
  alipayPublicKey: 'alipay_public_key'
});

// 统一支付接口
function unifiedPay(orderInfo) {
  return new Promise((resolve, reject) => {
    // 根据订单信息选择支付方式
    if (orderInfo.paymentMethod === 'wechat') {
      wechatPayInstance.createUnifiedOrder(orderInfo)
        .then(response => resolve(response))
        .catch(error => reject(error));
    } else if (orderInfo.paymentMethod === 'alipay') {
      alipayInstance.exec('alipay.trade.create', { bizContent: orderInfo })
        .then(response => resolve(response))
        .catch(error => reject(error));
    } else {
      reject(new Error('Unsupported payment method'));
    }
  });
}

// 使用示例
unifiedPay({ orderId: '123456', amount: 100, paymentMethod: 'wechat' })
  .then(result => console.log('Payment successful:', result))
  .catch(error => console.error('Payment failed:', error));
