因此，当我尝试发送XMLHttpRequest时得到qt.network.ssl: QSslSocket::connectToHostEncrypted: TLS initialization failed。
我使用Qt 5.12.2，imsvc2017_64。我该如何解决这个问题？
function requestCall(type){
var http = new XMLHttpRequest()
var url = "https://******";
var params = ""
params = "operator_id=1&call_id="+call_id;
console.log("Request (type): "+(type))
http.open("POST", url, true);
http.setRequestHeader("Content-type", "application/x-www-form- urlencoded");
http.setRequestHeader("Connection", "close");
http.onreadystatechange = function() { }
http.send(params);
}
