Access-Control-Allow-Headers 不允许请求头字段 X-MBX-APIKEY

如何解决Access-Control-Allow-Headers 不允许请求头字段 X-MBX-APIKEY

我收到此错误：Access-Control-Allow-Headers 不允许请求标头字段 X-MBX-APIKEY。我需要帮助我使用 th api Binance 和 ccxd，我想在浏览器中使用这个 javascript。

我在 javascript 中的代码：

'use strict';

 // const ccxt = require ('ccxt');

 let sum = 0;
 let i = 0;
 (async function () {
       const exchangeId = 'binance',exchangeClass = ccxt[exchangeId],exchange = new exchangeClass ({
           'apiKey': '***************','secret': '****************','timeout': 30000,'enableRateLimit': true,'verbose': true,// required! https://github.com/ccxt/ccxt/wiki/Manual#rate-limit
    })

    Object.entries((await exchange.fetchBalance()).total).forEach(item => {
      if (item[1] > 0) {
        const XMLHttpRequest = require("xmlhttprequest").XMLHttpRequest;

        const burl = "https://api.binance.com";

        let query = '/api/v1/ticker/24hr';

        query += `?symbol=${item[0]}USDT`;

        const url = burl + query;

        const ourRequest = new XMLHttpRequest();

        ourRequest.open('GET',url,true);
        ourRequest.onload = function(){
            const obj = JSON.parse(ourRequest.responseText);
            if (item[0] != 'USDT') {
              console.log("---------------------------------------------------");
              console.log(`${item[0]} : ${item[1]}`);
              console.log(`${item[0]} price : ${obj.lastPrice}$`);
              console.log(`Balance ${item[0]} : ${obj.lastPrice * item[1]}$`);
              sum += obj.lastPrice * item[1];
            } else {
              console.log("---------------------------------------------------");
              console.log(`${item[0]} : ${item[1]}`);
              console.log(`${item[0]} price : 1$`);
              console.log(`Balance ${item[0]} : ${item[1] * 1}$`);
              sum += 1 * item[1];
            }
            console.log(`Balance total usd : ${sum}$`);
        }
        ourRequest.send();
      }
    });
}) ();
