i'm trying create desktop app node-webkit. part of app require utilize of facebook get/post content profile (facebook user) utilize desktop app on personal computer.

regarding facebook api documentation (https://developers.facebook.com/docs/facebook-login/manually-build-a-login-flow/v2.0) , have manually implement login flow , utilize next uri redirect uri: https://www.facebook.com/connect/login_success.html

currently, in node-webkit app, via kid window (a popup), user can login facebook , authorize desktop app interact it's profile. here part of code:

var url = "https://www.facebook.com/dialog/oauth?client_id=myclientid&redirect_uri=https://www.facebook.com/connect/login_success.html&response_type=token&scope=publish_actions"; loginwindow = window.open(url, 'login facebook', 'location=yes,toolbar=yes,menubar=yes,directories=yes,status=yes,resizable=yes,scrollbars=yes,height=480,width=640', false);

after that, user redirected next uri , mentioned in doc, access token appear correctly:

https://www.facebook.com/connect/login_success.html#access_token=thebigtokenstring&expires_in=3864.

but appears few seconds , after url replaced https://www.facebook.com/connect/blank.html#_=_ (with security warning message).
