const ACCESS_SECRET = 'YOUR_ACCESS_SECRET';
const SIGNATURE_NONCE = crypto.randomBytes(4).toString('hex');
const TIMESTAMP = Math.floor(Date.now() / 1000).toString();

// 2. 生成签名
function generateSignature(accessKeyId, accessSecret, signatureNonce, timestamp) {
  const str = `AccessKeyId=${accessKeyId}&SignatureNonce=${signatureNonce}&Timestamp=${timestamp}`;
  const hmac = crypto.createHmac('sha1', accessSecret);
  hmac.update(str);
  return Buffer.from(hmac.digest('hex'), 'binary').toString('base64');
}

const signature = generateSignature(
  ACCESS_KEY_ID,
  ACCESS_SECRET,
  SIGNATURE_NONCE,
  TIMESTAMP
);

// 3. 发起请求
fetch('https://open.aicoin.com/api/v2/coin/ticker?' + new URLSearchParams({
