XMLHttpRequest to send a GET HTTP request with an username/password
I develop a Chrome uses XMLHttpRequest to send a GET HTTP request with an username/password to a basic-auth-protected URL, so that it can then "auto-login" to it afterwards (since Chrome caches credentials for HTTP basic-auth).
Here's the code I use:
var xml = new XMLHttpRequest();
xml.open('GET',<url>,false,<username>,<password>)
xml.send('');
After some additional research, I found out that it might have to do with Chrome 19 not supporting the username:pwd@url syntax for authenticating to basic-auth protected URLs, because when I send the XMLHttpRequest, I see this in Google Chrome's js console:
GET http://user:pass@domain.com 401 (Unauthorized)
Does anyone know whether it's a bug or if Chrome stopped supporting this feature?
My function
function autoLogin(domain, user, password) {
var httpAuth;
if (window.XMLHttpRequest) {
httpAuth = new XMLHttpRequest(); // code for IE7+, Firefox, Chrome, Opera, Safari
}
else if (window.ActiveXObject) {
httpAuth = new ActiveXObject("Microsoft.XMLHTTP"); // code for IE6, IE5
}
else {
alert("Seu browser não suporta autenticação xml. Favor autenticar no popup!");
}
var userName = domain + "" + user;
httpAuth.open("GET", "/_layouts/settings.aspx", false, userName, password);
httpAuth.onreadystatechange = function () {
if (httpAuth.status == 401) {
alert("Usuário e/ou senha inválidos.");
eraseCookie('AutoLoginCookieUserControl_User');
eraseCookie('AutoLoginCookieUserControl_Password');
}
else {
if ($(".pnlLogin").is(':visible')) {
$(".pnlLogin").hide();
$(".pnlUsuario").css("display", "block");
$(".avatar").css("display", "block");
var name = $().SPServices.SPGetCurrentUser({ fieldName: "Title" });
$(".loginNomeUsuario").html("Seja Bem Vindo(a) <br />" + name);
}
}
}
var userAgent = navigator.userAgent.toLowerCase();
$.browser.chrome = /chrome/.test(navigator.userAgent.toLowerCase());
if ($.browser.chrome == true) {
httpAuth.setRequestHeader("Authorization", "Basic " + btoa(userName + ":" + password));
}
try {
httpAuth.send();
}
catch (err) {
console.log(err);
}
}
You need to add headers to the XHR request manually.
xml.setRequestHeader("Authorization", "Basic " + btoa(username + ":" + password))
Demo here: http://jsbin.com/inuhiv/2 (NOte, there is nothing to auth, however look at devtools and see the request has auth header)
