Facebook login hangs at "XD Proxy" when page is installed via Chrome Web Store - facebook

The created the following web application:
http://www.web-allbum.com/
I also added it to the Chrome Web Store:
https://chrome.google.com/webstore/detail/idalgghcnjhmnbgbeebpdolhgdpbcplf
The problem is that when go to the Chrome Web Store and install this app the Facebook login windows hangs at a "XD Proxy" window. While the connect itself works, this blank window can confuse the users.
I did my research, and this seems to be a Chrome issue:
https://code.google.com/p/chromium/issues/detail?id=59285#c26
If you uninstall the app from Chrome, the problem disappears.
Is there any workaround for this problem?

This is my Facebook connect in case it helps:
FB.init({
appId : window.__FACEBOOK_APP_ID__,
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true, // parse XFBML
channelUrl : window.__MEDIA_URL__ + 'channel.html', // channel.html file
oauth : true // enable OAuth 2.0
});
FB.XD.Flash.init();
FB.XD._transport = "flash";
if (A.networks.facebook.connected) {
FB.getLoginStatus(function (response) {
// Stores the current user ID for later use
that.network_id = response.authResponse.userID;
if (!response.authResponse) {
// no user session available, someone you dont know
A.networks.facebook.connected = false;
}
callback();
});
}
else {
callback();
}
};
The Solution
Thanks to the reekogi reply I was able to workaround this issue. Here is the full implementation:
In order to avoid the XD Proxy problem, you have to connecte to Facebook without using the FB.login, this can be achieved by manually redirecting the user to Facebook page.
I had this login function in my code:
_facebook.connect_to_network = function (callback) {
FB.login(function (response) {
if (response.authResponse) {
console.log('Welcome! Fetching your information.... ');
FB.api('/me', function (response) {
// Stores the current user Id for later use
that.network_id = response.id;
console.log('Good to see you, ' + response.name + '.');
callback();
});
}
else {
console.log('User cancelled login or did not fully authorize.');
that.connected = false;
callback();
}
}, {scope: window.__FACEBOOK_PERMS__});
};
Which I replaced by this code:
_facebook.connect_to_network = function (callback) {
var url = 'https://www.facebook.com/connect/uiserver.php?app_id=' + window.__FACEBOOK_APP_ID__ + '&method=permissions.request&display=page&next=' + encodeURIComponent(window.__BASE_URL__ + 'authorize-window?my_app=facebook&my_method=login') + '&response_type=token&fbconnect=1&perms=' + window.__FACEBOOK_PERMS__;
window.open(url);
};
The new code opens a popup which connects to Facebook and returns to the url specified in the 'next' parameter. I added some extra parameters in this callback url so that the javascript code could check for it and close the popup.
This code is executed when the Facebook redirects to the callback url:
_facebook.parse_url_params = function () {
// This is the popup window
if (URL_PARAMS.my_method === 'login') {
window.opener.A.networks.facebook.connected = true;
self.close();
}
};
URL_PARAMS is just a helper object that contains all the url parameters.
I still believe that this is a Chrome issue, but since this workaround has worked and solved my problem I am marking this question as solved.

Could you call a javascript redirect to get permissions then redirect back to the http://www.web-allbum.com/connected uri?
I described this method in detail here ->
Permissions on fan page
EDIT:
The method I demonstrated before will be deprecated when OAuth 2.0 comes into the requirements.
Here is the code, adapted for OAauth 2.0 (response.session is replaced with response.authResponse)
<div id="fb-root"></div>
<script>
theAppId = "YOURAPPID";
redirectUri = "YOURREDIRECTURI"; //This is the page that you redirect to after the user accepts the permissions dialogue
//Connect to JS SDK
FB.init({
appId : theAppId,
cookie: true,
xfbml: true,
status: true,
channelURL : 'http://yourdomain.co.uk/channel.html', // channel.html file
oauth : true // enable OAuth 2.0
});
//Append to JS SDK to div.fb-root
(function() {
var e = document.createElement('script');
e.src = document.location.protocol + '//connect.facebook.net/en_US/all.js';
e.async = true;
document.getElementById('fb-root').appendChild(e);
}());
//Check login status and permissions
FB.getLoginStatus(function(response) {
if (response.authResponse) {
// logged in and connected user, someone you know
} else {
//Redirect to permissions dialogue
top.location="https://www.facebook.com/connect/uiserver.php?app_id=" + theAppId + "&method=permissions.request&display=page&next=" + redirectUri + "&response_type=token&fbconnect=1&perms=email,read_stream,publish_stream,offline_access";
}
});
</script>
Just tried and tested, worked fine in chrome.

I didn't try the solution proposed by Cesar, because I prefer to stick with Facebook's official javascript SDK.
Nevertheless I would like to add a few observations:
Indeed, the blocking problem only happened on Chrome after installing from Chrome Web Store. Uninstalling the web app solves the problem. (tested with legacy authentication method, without oauth 2.0). After closing the XD Proxy popup manually, my application was working properly.
After switching to asynchronous FB.init() and enabling oauth 2.0 option, my application would not even get a valid facebook connect status at login time ({authResponse: null, status: "unknown"})... Again, uninstalling it from the Chrome Web Store, it's working... ({authResponse: Object, status: "connected"})
No problem encountered with Safari, in any of these cases.

In IE8 - this can be caused by your flash version. I tried everything and nothing worked until I disabled flash. More details from this blog:http://hustoknow.blogspot.com/2011/06/how-facebooks-xdproxyphp-seemed-to-have.html#comment-form

Open a new browser tab in Chrome and see if you have the Facebook 'App' installed. If so, drag it to the bottom right corner to uninstall. Once uninstalled the XD Proxy will work.
Reference: facebook connect blank pop up on chrome

I was experiencing same problem for all browsers. When user clicked "login" button, a popup opened and hanged; and unless user killed browser process, it caused a high load on CPU. If user managed to see "allow" button and click it however, then it appeared a "xd proxy" blank window and nothing happened. That was the problem.
After long investigations, I noticed my new JS code which proxies setInterval/clearInterval/setTimeout/clearTimeout methods, caused this problem. Code is as follows:
window.timeoutList = new Array();
window.intervalList = new Array();
window.oldSetTimeout = window.setTimeout;
window.oldSetInterval = window.setInterval;
window.oldClearTimeout = window.clearTimeout;
window.oldClearInterval = window.clearInterval;
window.setTimeout = function(code, delay) {
window.timeoutList.push(window.oldSetTimeout(code, delay));
};
window.clearTimeout = function(id) {
var ind = window.timeoutList.indexOf(id);
if(ind >= 0) {
window.timeoutList.splice(ind, 1);
}
window.oldClearTimeout(id);
};
window.setInterval = function(code, delay) {
window.intervalList.push(window.oldSetInterval(code, delay));
};
window.clearInterval = function(id) {
var ind = window.intervalList.indexOf(id);
if(ind >= 0) {
window.intervalList.splice(ind, 1);
}
window.oldClearInterval(id);
};
window.clearAllTimeouts = function() {
for(var i in window.timeoutList) {
window.oldClearTimeout(window.timeoutList[i]);
}
window.timeoutList = new Array();
};
window.clearAllIntervals = function() {
for(var i in window.intervalList) {
window.oldClearInterval(window.intervalList[i]);
}
window.intervalList = new Array();
};
Removing these lines solved my problem. Maybe it helps to who experiences the same.

It appears this has been fixed in Chrome. No longer happens for us in Mac Chrome 15.0.874.106

Another workaround is to use this code after you call FB.init():
if (/chrome/.test(navigator.userAgent.toLowerCase())) {
FB.XD._origin = window.location.protocol + '//' + document.domain + '/' + FB.guid();
FB.XD.Flash.init();
FB.XD._transport = 'flash';
}
The pop-up window remains open and blank, but I found that in my Chrome Web Store app, the authentication goes through when this code is used.
This bug is also filed on Facebook Developers here: http://developers.facebook.com/bugs/278247488872084

I've been experiencing the same issue in IE9, and it seemed to stem from upgrading to Flash Player 10. The answers suggested already did not work for me and I'd lost hope in trying to fix it since finding an open bug at Facebook covering it. But Henson has posted an answer on a similar question that fixed it for me. In the JavaScript in my site master I removed the lines
FB.UIServer.setLoadedNode = function (a, b) {
//HACK: http://bugs.developers.facebook.net/show_bug.cgi?id=20168
FB.UIServer._loadedNodes[a.id] = b;
};
and now it works. (N.B. I have not checked to see if the IE8 issue those lines were intended to overcome returns.)

Unexpected behavior for Facebook Sharing [duplicate]

This question already has an answer here:
Facebook ignoring OG image on first share
(1 answer)
Closed 6 years ago.
First of all hi and thanks in advance to anyone who can help with this because I've been going crazy over this for weeks now.
So I've got a website which lists gif taken from my mobile application (which are then stored on AWS and my visitors ( I haven't found a use for me to have users) can share these gifs on facebook using the facebook sdk.
The problem appears when I try sharing an image for the first time
This is what the share dialog shows the first time I click on my sharing button:
http://i.stack.imgur.com/lNVNF.png
and then I close and reclick the same button and now it works:
http://i.stack.imgur.com/YsDUm.png
Now I've been trying to find a way to make this work on the first sharing attempt but to no avail.
I am using meteor in combination with biasport:facebook-sdk and Amazon S3 for the hosting of my files.
Edit here is the code used:
FRONT SIDE
HTML
<div class="facebook share">
<img src="/gallery/fb.png">
</div>
Javascript
Template.*templateName*.events({
'click .facebook': function(e){
e.preventDefault();
e.stopPropagation();
// this is in a modal so I store the data I need
// (events have photos which in turn contain a url to the gif
var url = Session.get('event').photos[Session.get("id")].url;
FB.ui({
method: 'share',
href: url
});
}
SERVER SIDE
JAVASCRIPT
if(Meteor.isClient) {
window.fbAsyncInit = function() {
FB.init({
appId : 'APP_ID',
status : true,
xfbml : true,
version : 'v2.5'
});
};
}
Edit: I found a manual solution using exec future and curl
so first I added a call to a meteor method on the share that updates the facebook crawler
JAVASCRIPT
Template.*templateName*.events({
'click .facebook': function(e){
e.preventDefault();
e.stopPropagation();
// this is in a modal so I store the data I need
// (events have photos which in turn contain a url to the gif
var url = Session.get('event').photos[Session.get("id")].url;
Meteor.call('updateCrawler', url, function(){
FB.ui({
method: 'share',
href: url
});
});
}
Then I defined my meteor method as such
JAVASCRIPT
Meteor.methods({
updateCrawler: function(url){
var future = new Future();
cmd = 'curl -X POST -F "id=' + url + '" -F "scrape=true" -F "access_token={my_access_token}" "https://graph.facebook.com"';
exec(cmd, function(error){
if (error){
console.log(error);
}
future.return();
});
future.wait();
}
});
it's ugly but since I'd have to wait for the crawler to update and it works I'll leave this here for future use for someone maybe
Edit2:
I did not use og tags at all since I was simply sharing a url to aws directly and not a url to my website
I worked around this problem by calling the Facebook API direct from the server to make it scrape the og data by requesting info on the page. First time round it doesn't have the image cached but second time it does so this workaround does the initial call before sharing.
Use an access token for your facebook app and call the below in an ajax call and await the response before opening share dialog. Replace Google address with your own uri encoded address https://graph.facebook.com/v2.5/?id=http%3A%2F%2Fwww.google.co.uk&access_token=xxxxx
EDIT:
As per comments, here is my server side method for calling this which I use when posts etc are inserted to make the initial call and prompt a scrape from fb:
var getTheOGInfo = function (link)
{
if (!link || link.slice(0, 4).toLowerCase() != "http"){
throw new Meteor.Error("og-info-bad-url", "Function requires an unencoded fully qualified url");
return false;
}
var url = "https://graph.facebook.com/v2.5/{{{{id}}}}?access_token={{{{token}}}}&fields=og_object{id,description,title,type,updated_time,url,image},id,share";
var token = Meteor.settings.private.fb.token;
if (!token){
throw new Meteor.Error("og-info-no-token", "Function requires a facebook token in Meteor.settings.private.fb.token");
return false;
}
var link_id = encodeURIComponent(link);
url = url.replace('{{{{token}}}}', token).replace('{{{{id}}}}', link_id);
var result = HTTP.get(url, {timeout:1000});
return result;
}
Or for your purposes you may not want anything that might be blocking so you could change the last two lines to be aynchronous:
var result = HTTP.get(url, {timeout:1000});
return result;
//Replace with non blocking
HTTP.get(url, {timeout:1000}, function(err, result){console.log('something asynchronous', err, result);});
return true;

How do I use FB.getLoginStatus() on page load if Parse.com handles init?

Documentation for Parse.FacebookUtils.init() states:
The status flag will be coerced to 'false' because it interferes with Parse Facebook integration. Call FB.getLoginStatus() explicitly if this behavior is required by your application.
Unfortunately, when I try to call FB.getLoginStatus(), I get TypeError: Cannot read property 'getLoginStatus' of undefined. Is there either a callback that I can use to know when FB is loaded, or some other way to check the login status of a user on page load?
It would help to see some code, it sounds like the SDK hasn't loaded when you call getLoginStatus().
Anyway this may help, I took Facebook's basic Login flow and added Parse around it. It checks when the DOM is loaded so you could use some of this logic also.
Simple Facebook Login test with Parse - view source
Hope this helps.
I ended up using promises to resolve FB after it's loaded.
var fbDeferred = $q.defer();
$window.fbAsyncInit = function() {
Parse.FacebookUtils.init({
appId : 'xxxxxx',
xfbml : true,
version : 'v2.2'
});
fbDeferred.resolve(FB);
};
var getFB = function(){
return fbDeferred.promise;
}
var getFBLoginStatus = function(){
return getFB().then(function(FB){
//**FB is now available**
FB.getLoginStatus(function(response) {
if (response.status !== 'connected'){
...
}else{
...
}
});
});
});

Facebook login popup doesn't close after login on iOS8

I'm testing my web app login flow on the iOS8. I notice that on iOS8, the login dialogue pops up, but after logging in, it just stays there, showing a blank page.
The login works, because the page behind it shows the user information, but the popup just stays there, while it should close automatically. On iOS7 and iOS6 it does close. On desktop browsers it closes too.
I've tested some other random sites (for example brainfall.com) using FB.login(): same thing.
Does anyone have a fix for this?
Any help is much appreciated!
Check this:
fb_window_redirect
Override de window.open method. This allows you to know what windows are opened.
Then you can redirect the window opened by the FB SDK.
...
window._open = window.open; // saving original function
//Override the function
window.open = function(url,name,params) {
var new_window = window._open(url,name,params);
if (typeof onWindowOpen === "function") {
onWindowOpen(url, name, params, new_window);
}
return new_window;
};
...
var openedWindows = [];
var fbWindows = [];
function onWindowOpen(url, name, params, new_window) {
...
// Filter the facebook oauth request
if (url.contains('facebook.com')
&& url.contains('oauth')) {
fbWindows.push(new_window);
}
openedWindows.push(new_window);
}
...
//On fb login button pressed callback:
FB.login(function(response) {
//Try login
if(response.authResponse) {
//Login succesful
// Fb window redirect.
// see onWindowOpen
var fbwin = fbWindows[0];
var redirect_url = ''
fbwin.location = redirect_url;
}
},
{scope: 'email,publish_stream,user_birthday'});
...

Facebook JS SDK : Alternatives to popup box of FB.Login

I'm using Facebook JS SDK to develop a Facebook Page Tab application. There is a button in landing page. When clicked, user will be asked to install the App if they haven't done so.
The codes are as follow:
<script type="text/javascript">
function installApp() {
FB.login(function(response) {
if (response.authResponse) {
var accessToken = response.authResponse.accessToken;
}
if (response.status === 'connected') {
window.location = 'share.php';
} else {
alert('Please install app first');
}
}, {scope:'friends_likes,email'});
}
</script>
By default FB.Login will result in a popup box asking for permission. Is there any alternative way to AVOID the popup box? I have seen other Facebook apps successfully achieve this, but I have no idea how they did it.
You can use the Javascript Api with a Graph Api call for this,
function fbLogin() {
var oauth_url = 'https://www.facebook.com/dialog/oauth/';
oauth_url += '?client_id=APP_ID_HERE';
oauth_url += '&redirect_uri=' + encodeURIComponent('https://apps.facebook.com/APP_NAMESPACE/');
oauth_url += '&scope=email'
window.top.location = oauth_url;
}
then you can call it in a custom button with the onclick event:
Custom Login
Have you went through the Authentication documentation?
It pretty much cover all of the options that are available to you. i.e.:
Client-Side Authentication
Server-Side Authentication
Authentication within a Page Tab
You can probably use any of those approaches, but the 3rd probably will fit best.

Facebook App in Profile Tab: problems getting the user session

I'm working in a mini-app, which will have 3 pages, and i want all the interaction to happen inside a profile-tab.So, using javascript, i want to show/hide a few divs, which i'll populate using the FBJS ajax object.
My problem is, i'm not getting the user session in the ajax calls.As documentation is extremely confusing, i've ended up not knowing if this is possible at all.Any ideas?
You can get the user's id if you require login from your ajax request on a profile tab. For instance:
var ajax = new Ajax();
ajax.responseType = Ajax.RAW;
ajax.ondone = function(data) {
console.log('done');
console.log(data);
}
ajax.onerror = function(data) {
console.log('error');
console.log(data);
}
ajax.requireLogin = true;
ajax.post('http://DOMAIN/add_story', {story: story});
The requireLogin = true part will cause an authorization window to popup. If they agree, you can get the user ID in your AJAX handler using the PHP SDK, like:
$facebook->getUser();
