XmlListModel - Host requires authentication

aydens

Hi,
I'm trying to get data from Yammer with their API, with XmlListModel object without success. :-(
I'm getting the following error: "Host requires authentication"

If I try to access the URL (XmlListModel.source) via my web browser it works fine.

Someone know how to solve this issue?

thanks,
Ayden.

Can you please post a code snippet of your code?

Yes, Although I'll have to register again to get new oauth_consumer_key :-)

This code is inspired by the example: "http://wiki.forum.nokia.com/index.php/QML_OAuth":http://wiki.forum.nokia.com/index.php/QML_OAuth

Because the code is too long, I'll split the post

var oauth_token
var oauth_token_secret

var authorized = false;
var mUrl = url.toString();
var code = "";
if (mUrl.indexOf("https://www.yammer.com") > -1) {
var query = mUrl.substring(mUrl.indexOf('?') + 1);
var vars = query.split("&");
for (var i=0;i<vars.length;i++) {
var pair = vars[i].split("=");
if (pair[0] == "oauth_verifier") {
console.debug("authorized!!!");
authorized = true;
code = pair[1];
}
}
}
if (authorized) {
