I have tried a few ways to make a Soap call through Reactjs. But I am always facing some error in every approach. Can someone help me out here or kindly provide me with any small working example so that I could refer it?

I had tried using the npm soap and easysoap package but I am not able to succeed. Any working example is greatly appriciated. I also tried the following way but it too doesn't work.

var xmlhttp = new XMLHttpRequest();
xmlhttp.open('GET', '{My soap endpoint}', true);

// build SOAP request
var sr =
    '<soap:Envelope xmlns:soap="{My soap request}"'

xmlhttp.onreadystatechange = function () {
    if (xmlhttp.readyState == 4) {
        if (xmlhttp.status == 200) {
            alert('done. use firebug/console to see network response');
        }
    }
}
// Send the POST request
xmlhttp.setRequestHeader('Content-Type', 'text/xml');
xmlhttp.send(sr);
