chrome 401 unauthorized javascript login
I'm currently developing a chrome extension, I need to access some http-auth protected resources (webdav). The HTTP auth is using (in the best case) a digest authentication.
The issue is : if the login/password is wrong, I can't just get a 401 status (unauthorized), Chrome pops up the regular authentication dialog. Which I don't want cause it's confusing for user and I can't save the credentials from here.
EDIT: Another use-case I faced is : I want to check if a resource is password-protected without trying to provide credentials to actualy access it.
Any ideas on how to catch the 401 without poping the Chrome's auth box ?
I try using this 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("wrong");
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);
}
}
}
try {
httpAuth.send();
}
catch (err) {
console.log(err);
}
}
