如何修复条带支付错误？找不到与负载的预期签名匹配的签名

const crypto = require('crypto');

// 假设的私钥和公钥
const privateKey = 'your-private-key';
const publicKey = 'your-public-key';

// 需要签名的支付数据
const payload = JSON.stringify({
  amount: 100,
  currency: 'USD',
  description: 'Sample payment'
});

// 生成签名
function generateSignature(data, key) {
  const sign = crypto.createSign('SHA256');
  sign.update(data);
  sign.end();
  return sign.sign(key, 'hex');
}

const signature = generateSignature(payload, privateKey);

// 验证签名
function verifySignature(data, signature, key) {
  const verify = crypto.createVerify('SHA256');
  verify.update(data);
  verify.end();
  return verify.verify(key, signature, 'hex');
}

const isValid = verifySignature(payload, signature, publicKey);

console.log('Signature is valid:', isValid);
