how to send uri to facebook in the right format - facebook

Question

I need help on facebook login wth app. I have a website http://отдых-сицилия.рф. I did configured this in facebook app, and I am trying to login from my application.
I have the code below:
window.fbAsyncInit = function() {
FB.init({
appId : 'code', // App ID
channelUrl : '//отдых-сицилия.рф/channel.php', // Channel File
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true // parse XFBML
});
// Here we subscribe to the auth.authResponseChange JavaScript event. This event is fired
// for any authentication related change, such as login, logout or session refresh. This means that
// whenever someone who was previously logged out tries to log in again, the correct case below
// will be handled.
FB.Event.subscribe('auth.authResponseChange', function(response) {
// Here we specify what we do with the response anytime this event occurs.
if (response.status === 'connected') {
// The response object is returned with a status field that lets the app know the current
// login status of the person. In this case, we're handling the situation where they
// have logged in to the app.
// FB.login({scope:'email,hometown'});
FB.api('/me', function(response) {
document.getElementById('nome').value = response.name;
if(response.email){
document.getElementById('email').value = response.email;
}
document.getElementById('fbusername').value = response.username;
document.getElementById('fbname').value = response.first_name;
document.getElementById('fbsurname').value = response.last_name;
document.getElementById('nazionalita').value = response.locale;
if(response.hometown){
document.getElementById('citta').value = response.hometown.name;
}
});
} else if (response.status === 'not_authorized') {
// In this case, the person is logged into Facebook, but not into the app, so we call
// FB.login() to prompt them to do so.
// In real-life usage, you wouldn't want to immediately prompt someone to login
// like this, for two reasons:
// (1) JavaScript created popup windows are blocked by most browsers unless they
// result from direct interaction from people using the app (such as a mouse click)
// (2) it is a bad experience to be continually prompted to login upon page load.
FB.login({scope:'email,hometown'});
} else {
// In this case, the person is not logged into Facebook, so we call the login()
// function to prompt them to do so. Note that at this stage there is no indication
// of whether they are logged into the app. If they aren't then they'll see the Login
// dialog right after they log in to Facebook.
// The same caveats as above apply to the FB.login() call here.
FB.login({scope:'email,hometown'});
}
});
};
// Load the SDK asynchronously
(function(d){
var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "//connect.facebook.net/it_IT/all.js";
ref.parentNode.insertBefore(js, ref);
}(document));
this code works very good on other 2 websites.
What I noticed is that when I open the login popup, the url is:
redirect_uri=http%3A%2F%2Fwww.facebook.com%2Fdialog%2Freturn%2Farbiter%3Frelation%3Dopener%26close%3Dtrue%23origin%3Dhttp%253A%252F%252F%25D0%25BE%25D1%2582%25D0%25B4%25D1%258B%25D1%2585-%25D1%2581%25D0%25B8%25D1%2586%25D0%25B8%25D0%25BB%25D0%25B8%25D1%258F.%25D1%2580%25D1%2584%252Ff32358e929d241c&app_id={APP_ID}&display=popup
so, the website url is not correct. How can I pass this url correctly?Or what cand I do?
Thank you!
