Пытаюсь отправить POST-запрос на веб-сервер. А вместо этого от отправляется OPTIONS.
Заголовок запроса:

Сам код:
var idClient, emailClient, ipClient, dateClient, urlClient, fileHashClient;
idClient = Date.now();
urlClient = window.location.href;
dateClient = Date.now();
var xhr = new XMLHttpRequest();
var json = JSON.stringify({
id: idClient,
email: emailClient,
ip: ipClient,
date: dateClient,
url: urlClient,
fileHashClient: fileHashClient
});
alert(json);
xhr.open("POST", "http://127.0.0.1:5000/", true)
xhr.setRequestHeader('Content-type', 'application/json; charset=utf-8');
//http.setRequestHeader("Content-length", json.length);
xhr.onreadystatechange = function () {
if (xhr.readyState == 4 && xhr.status == 200) {
alert(xhr.responseText);
}
}
xhr.send(json);
Где я ошибся?
