一码多付如何搭建

// 引入支付SDK
const wxPay = require('wxpay-sdk');
const alipay = require('alipay-sdk');

// 初始化支付实例
const wxPayInstance = new wxPay({
  appId: 'your_wx_app_id',
  mchId: 'your_wx_mch_id',
  apiKey: 'your_wx_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 createPayment(orderInfo) {
  return new Promise((resolve, reject) => {
    // 调用微信支付接口
    wxPayInstance.createUnifiedOrder(orderInfo, (err, result) => {
      if (err) return reject(err);
      resolve({ type: 'wechat', data: result });
    });

    // 调用支付宝支付接口
    alipayInstance.exec('alipay.trade.precreate', { bizContent: orderInfo }, (err, result) => {
      if (err) return reject(err);
      resolve({ type: 'alipay', data: result });
    });
  });
}

// 使用示例
createPayment({ out_trade_no: '123456', total_amount: '100.00', subject: 'Test Payment' })
  .then(result => console.log(result))
  .catch(err => console.error(err));

const QRCode = require('qrcode');

function generateQRCode(data) {
  return new Promise((resolve, reject) => {
    QRCode.toDataURL(data, (err, url) => {
      if (err) return reject(err);
      resolve(url);
    });
  });
}
