是否可以发送http请求直到它通过

如何解决是否可以发送http请求直到它通过

我正在尝试向我的服务器发送 HTTP 请求，直到请求通过。我当前的实现每秒发送太多请求，这会导致浏览器滞后。我试图每 2 秒发出一次请求。我的代码有问题还是我的实现有问题？

如果有更好的方法（除了多次发送请求），请随意填写

const GetWeightXML = () => {
    var xmlhttp = new XMLHttpRequest();
    var interval_1;
    xmlhttp.onreadystatechange = function () {
        if (this.readyState == 4 && this.status == 200) {
            if (inverval_1 != null) {
                clearInterval(interval_1);
            }
            var interval = setInterval(GetWeightXML_Recieved(this,interval),1000);
        }
        else if (this.status == 404) {
            interval_1 = setInterval(GetWeightXML,2000);
        }
    }

    let request_url = `${window.location.protocol}//${window.location.hostname}:${window.location.port}/Temp/weight.xml`;

    xmlhttp.open("GET",request_url,true);
    xmlhttp.send();
}

function GetWeightXML_Recieved(xml,interval) {
    var xmlDoc = xml.responseXML;

    let finished = xmlDoc.getElementsByTagName('Finished').childNodes[0].nodeValue;
    if (finished == null || finished == "") {
        return;
    }

    if (finished == "true") {
        clearInterval(inverval);
        return;
    }

    let currWeight = document.getElementsByClassName('current-weight')[0];
    let timeElapsed = document.getElementsByClassName('time-elapsed')[0];

    currWeight.innerText = "Current Weight: " + xmlDoc.getElementsByTagName('Weight').childNodes[0].nodeValue;
    timeElapsed.innerText = "Time Elapsed: " + xmlDoc.getElementsByTagName('Time').childNodes[0].nodeValue;
}
