ccxt的bitmart签名无效错误

Question

createOrder: async (req,res) =>; { 常量{ 象征， 数量， 价格， 边 } = 请求体；

      const t = Math.floor(new Date().getTime());
      console.log(t);

  const timestamp = t;
  const memo = '*****';
  const queryString = {"symbol":"BMX","side":"BUY"};
  const SecretKey = '***************************************';
  const signat = new CryptoJS.HmacSHA256(timestamp + "#" + memo + "#" + queryString, SecretKey);
  const s = signat.toString();
  console.log(s); 

    const exchange = new ccxt.bitmart({
        apiKey: process.env.apiKey,
        secret: process.env.secret,
        uid: process.env.uid,

    //console.log(exchange);
  
    try {
        console.log("inside create order");
         const s = symbol;
         const a = amount ;// BMX
         const p = price ;// BTC
         const buyOrsell = side;
        // cost = amount * price = 2 * 9000 = 18000 (USD)
         const order = await exchange.createOrder (s, 'market', buyOrsell, a, p);
         
   
         console.log (order);
         res.json(order);       
      
    } catch  (e) {
        
        if (e instanceof ccxt.NetworkError) {
            console.log (exchange.id, 'createOrder failed due to a network error:', e.message)
            // retry or whatever
            // ...
        } else if (e instanceof ccxt.ExchangeError) {
            console.log (exchange.id, 'createOrder failed due to exchange error:', e.message)
            // res.json(exchange.id, 'createOrder failed due to exchange error:', e.message);       

            // retry or whatever
            // ...
        } else {
            console.log (exchange.id, 'createOrder failed with:', e.message)
            // retry or whatever
            // ...
        }
    }
    
    
    // catch (err) {
    //     res.json({ message: err});
    //     console.log(err);
    // }
}

由于交换错误，

bitmart createOrder 失败：bitmart {"message":"标头 X-BM-SIGN 错误","code":30005,"trace":"74530845-d504-46b1-b1f9-1374ae11cbc6","data ":{}}

这个标头在哪里给出？ 怎么解决这个问题？
