Javascript not running on Facebook iframe - javascript

I have a django project which is intended for a facebook application. In the project, the invite friends module runs fine in localhost!
But while it is loaded in facebook application, the javascript responsible for displaying the friends list doesn't work. Although the libraries are properly loaded.
I don't know why it is so. May be some iframe problem.
Here is the javascript code
<script type="text/javascript">
window.fbAsyncInit = function() {
FB.init({appId: '460948667348013', cookie: true});
FB.getLoginStatus(function(response) {
if (response.status === 'connected') {
FB.api('/me', function(response) {
// alert('Your name is ' + response.name);
console.log('Your name is ' + response.name);
init();
});
} else if (response.status === 'not_authorized') {
alert('the user is logged in to Facebook, but has not authenticated your app');
} else {
alert('the user is not logged in to Facebook.');
}
});
}
function init() {
FB.api('/me', function(response) {
$("#username").html("<img src='https://graph.facebook.com/" + response.id + "/picture'/><div>" + response.name + "</div>");
$("#jfmfs-container").jfmfs({
max_selected: 15,
max_selected_message: "{0} of {1} selected",
friend_fields: "id,name,last_name",
pre_selected_friends: [1014025367],
exclude_friends: [1211122344, 610526078],
sorter: function(a, b) {
var x = a.last_name.toLowerCase();
var y = b.last_name.toLowerCase();
return ((x < y) ? -1 : ((x > y) ? 1 : 0));
}
});
$("#jfmfs-container").bind("jfmfs.friendload.finished", function() {
window.console && console.log("finished loading!");
});
$("#jfmfs-container").bind("jfmfs.selection.changed", function(e, data) {
window.console && console.log("changed", data);
});
$("#logged-out-status").hide();
$("#show-friends").show();
});
}
$("#show-friends").live("click", function() {
var friendSelector = $("#jfmfs-container").data('jfmfs');
$("#selected-friends").html(friendSelector.getSelectedIds().join(', '));
});
function sendRequest() {
var friendSelector = $("#jfmfs-container").data('jfmfs');
var sendUIDs = friendSelector.getSelectedIds().join(', ');
// Use FB.ui to send the Request(s)
FB.ui({method: 'apprequests',
to: sendUIDs,
title: 'My Great Invite',
message: 'Check out this Awesome App!',
}, callback);
}
function callback(response) {
// alert('callback called');
var friendSelector = $("#jfmfs-container").data('jfmfs');
var sendUIDs = friendSelector.getSelectedIds().join(',');
var uids = sendUIDs.split(',');
var query = '';
for(i=0;i<uids.length;i++){
if(i==0){
query = query + 'to[' + i + ']=' + uids[i];
}
else{
query = query + '&to[' + i + ']=' + uids[i];
}
}
console.log(query);
if(response){
// alert('successful');
window.location.assign("/?"+ query)
}
else{
alert('failure');
}
}
</script>
Please help ! I am stuck with this problem.

The issue may be SSL issues.
Facebook has made many changes in few months ago.
Also you need to keep update with Facebook developer blog.
So I am going to try to explain few things I suspected.
App on Facebook
Your Canvas Page should be https://apps.facebook.com/yourchoosenname
1a. Your Canvas URL should be https://yoursite.com/yourapplication/
Website
http://yoursite.com/
Page Tab
Your Secure Canvas should be https://yoursite.com/yourapplication/
Your Page Tab URL should be https://yoursite.com/yourapplication/
Your Secure Page Tab URL should be https://yoursite.com/yourapplication/
In this case you will need SSL Certificate for site so You can find reliable yet cheap digital certificate from Here .
This mandatory for any Application to work on facebook.
Hope this will help you and others

Twilio chat events memberUpdated, and userInfoUpdated never fired

i'm looking on what cases are these events is firing, i have implement it on these code
jQuery(document).ready(function() {
var chatChannel;
var chatClient;
var username;
var $input = $('#chat-input');
$.post("/tokens", function(data) {
username = data.username;
chatClient = new Twilio.Chat.Client(data.token);
chatClient.getSubscribedChannels().then(createOrJoinGeneralChannel);
});
function createOrJoinGeneralChannel() {
// Get the general chat channel, which is where all the messages are
// sent in this simple application
// print('Attempting to join "general" chat channel...');
var promise = chatClient.getChannelByUniqueName("#{params[:chat_channel]}");
promise.then(function(channel) {
chatChannel = channel;
console.log("#{params[:chat_channel]} is exist");
console.log(chatChannel);
setupChannel();
return channel.getMembers();
// $input.removeClass('.hidden')
})
.then(function(members){
members.forEach(function(member){
console.log('member', member);
member.on('userInfoUpdated', function(){
console.log('userInfoUpdated', member);
})
})
})
.catch(function() {
// If it doesn't exist, let's create it
console.log("creating #{params[:chat_channel]} channel");
chatClient.createChannel({
uniqueName: "#{params[:chat_channel]}",
friendlyName: 'General Chat Channel'
}).then(function(channel) {
console.log("Created #{params[:chat_channel]} channel:");
console.log(channel);
chatChannel = channel;
setupChannel();
});
});
}
function setupChannel() {
chatChannel.join().then(function(channel) {
printMessage(username + ' joined the chat.');
chatChannel.on('typingStarted', showTypingStarted);
chatChannel.on('typingEnded', hideTypingStarted);
chatChannel.on('memberJoined', notifyMemberJoined);
chatChannel.on('memberLeft', notifyMemberLeft);
chatChannel.on('memberUpdated', updateMemberMessageReadStatus);
});
chatChannel.on('messageAdded', function(message) {
printMessage(message.author + ": " + message.body);
});
}
function updateMemberMessageReadStatus(member){
console.log('memberUpdated');
console.log('member.lastConsumedMessageIndex', member.lastConsumedMessageIndex);
console.log('member.lastConsumptionTimestamp', member.lastConsumptionTimestamp);
}
function leaveCurrentChannel() {
if (chatChannel) {
chatChannel.leave().then(function (leftChannel) {
console.log('left ' + leftChannel.friendlyName);
leftChannel.removeListener('messageAdded', function(message) {
printMessage(message.author + ": " + message.body);
});
leftChannel.removeListener('typingStarted', showTypingStarted);
leftChannel.removeListener('typingEnded', hideTypingStarted);
leftChannel.removeListener('memberJoined', notifyMemberJoined);
leftChannel.removeListener('memberLeft', notifyMemberLeft);
leftChannel.removeListener('memberUpdated', updateMemberMessageReadStatus);
});
}
}
function showTypingStarted(member) {
console.log('somebody is typing');
$('#is_typing').html(member.identity + ' is typing...');
}
function hideTypingStarted(member) {
$('#is_typing').html('');
}
function notifyMemberJoined(member) {
console.log('notifyMemberJoined');
printMessage(member.identity + ' joined the channel');
}
function notifyMemberLeft(member) {
console.log('notifyMemberLeft');
printMessage(member.identity + ' left the channel');
}
$input.on('keydown', function(e) {
if (e.keyCode == 13) {
chatChannel.sendMessage($input.val());
$input.val('');
} else {
//console.log('typing');
chatChannel.typing();
}
});
window.addEventListener("beforeunload", function (e) {
// var confirmationMessage = "\o/";
(e || window.event).returnValue = leaveCurrentChannel(); //Gecko + IE
return leaveCurrentChannel(); //Webkit, Safari, Chrome
});
});
and i've take alook to the console to see if my
console.log('userInfoUpdated', member);
or these guys
console.log('memberUpdated');
console.log('member.lastConsumedMessageIndex', member.lastConsumedMessageIndex);
console.log('member.lastConsumptionTimestamp', member.lastConsumptionTimestamp);
and they are never fired, during my test on the chat events, and i'm confused on how exactly i'm going to display how my users online or the status of a message is read or unread
so please enlighten me on the case, thank you
Twilio developer evangelist here.
According to the JS docs for the latest version of Twilio Chat, the event you need to listen for on members is just called 'updated'. So, listening for 'userInfoUpdated' won't work.
I would also recommend that within this code:
chatChannel.join().then(function(channel) {
//...
chatChannel.on('memberUpdated', updateMemberMessageReadStatus);
//...
})
you use the channel passed to the callback, rather than the original chatChannel object. Like this:
chatChannel.join().then(function(channel) {
//...
channel.on('memberUpdated', updateMemberMessageReadStatus);
//...
})
I don't know if this will fix the issue, but I can't think of anything else right now.

Check for an specific .js file being served in response

I need to detect whether an specific .js file was served in a http response and additionally, check the domain it came from, like this:
I need to automatically detect the lack of the js file and email the incidence
I tried Net::Http, rest-client, mechanize and a lot of gems, they just return the html header. It seems I need to monitor http traffic with tools like PhantomJS and checking for the file, but is there any rubyesque way of doing this?
Thanks in advance
I ended with the phantomjs approach. A ruby script iterate over a database table and then calls this phantomjs script for each record representing an URL
This is the phantomjs script
var page = require('webpage').create(),
system = require('system'),
address,
isScript = false;
var fs = require('fs');
// main
analizePage(system.args[1]);
//open page.
//onResourceRequested event, compares domain of each one with 'my.domain.net'
//append to a log file: -1 for failed url, 1 for script presence, 0 for no script presence
function analizePage(address){
page.open(address, function (status) {
if (status !== 'success') {
console.log('FAIL to load the address ' + address);
fileWriter(-1, address);
}
else
{
if (!isScript){
fileWriter(0, address);
}
else
{
fileWriter(1, address);
}
console.log('Has script: ' + isScript);
}
phantom.exit(0);
});
page.onResourceRequested = function (req) {
try {
var link = document.createElement('a');
link.setAttribute('href', req.url); //extract asset's domain from URL
if (link.hostname == 'my.domain.net') {
isScript = true;
}
} catch(e) {
console.log("PAGE OPEN ERROR: " + e);
}
};
}
function fileWriter(type, line){
try {
fs.write("scriptlog.csv", type + ',' + line + ',' + Date.now() + ',' + system.args[2] + '\n', 'a');
} catch(e) {
console.log("FILE ERROR: " + e);
}
}

Check if user liked my FB page on my external website

I know, that there are lot of questions with this error, but still I can't find solution for this error:
Given URL is not permitted by the application configuration.: One or
more of the given URLs is not allowed by the App's settings. It must
match the Website URL or Canvas URL, or the domain must be a subdomain
of one of the App's domains.
I'm working with this example:
$(document).ready(function() {
FB.login(function(response) {
if (response.status == 'connected') {
var user_id = response.authResponse.userID;
var page_id = "383152115092391"; //"383152115092391"; // coca cola page https://www.facebook.com/cocacola
var fql_query = "SELECT uid FROM page_fan WHERE page_id=" + page_id + " and uid=" + user_id;
FB.api('/me/likes/'+page_id, function(response) {
if (response.data[0]) {
$("#container_like").show();
} else {
$("#container_notlike").show();
}
});
} else {
// user is not logged in
}
});
});
jsfiddle example
And this is my DB app configuration:
basic settings
advanced settings
Can you please tell me, what am I missing?

Why is this loop through facebook posts not working?

I'm playing around with the Facebook API in Javascript to try and pull posts from Facebook. I copied code from this page in the documentation. The function will access the page given and actually produce a response. But, response.length and response[i] are returning as "undefined" thus making it impossible for the loop to work. Why is this happening?
<button onclick="ShowMyPosts()">Show posts</button>
<script language="javascript" type="text/javascript">
function ShowMyPosts() {
FB.api('/TheWalkingDeadAMC/posts', { limit: 3 }, function(response) {
console.log(response)
console.log(response.length)
for (var i=0, l=response.length; i<l; i++) {
var post = response[i];
console.log(post)
if (post.message) {
console.log('Message: ' + post.message);
} else if (post.attachment && post.attachment.name) {
console.log('Attachment: ' + post.attachment.name);
}
}
}
)
console.log("successfully ran function")
};
</script>
How I get an access token. Is this incorrect?
FB.login(function(response) {
if (response.authResponse) {
var access_token = FB.getAuthResponse()['accessToken'];
console.log('Access Token = '+ access_token);
FB.api('/me', function(response) {
console.log('Good to see you, ' + response.name + '.');
});
} else {
console.log('User cancelled login or did not fully authorize.');
}{scope: 'read_stream'}
});
When you query the Graph API - most results will be inside data key...
Using Graph API Explorer you can test your call and see what is the result without having to write a single line of code.
This is a direct link to your Graph API call test. as you can see data holds the posts.
So, you need to loop through response.data and not response.
The code should look like this:
function ShowMyPosts() {
FB.api('/TheWalkingDeadAMC/posts', { limit: 3 }, function(response) {
console.log(response.data);
console.log(response.data.length)
for (var i=0, l=response.data.length; i<l; i++) {
var post = response.data[i];
console.log(post)
if (post.message) {
console.log('Message: ' + post.message);
} else if (post.attachment && post.attachment.name) {
console.log('Attachment: ' + post.attachment.name);
}
}
}
I think the issue was that my FB.login was incorrect. This is the correct code below:
FB.login(
function(response) {
if (response.authResponse) {
var access_token = FB.getAuthResponse()['accessToken'];
console.log('Access Token = '+ access_token);
FB.api('/me', function(response) {
console.log('Good to see you, ' + response.name + '.');
});
} else {
console.log('User cancelled login or did not fully authorize.');
}},
{scope: 'read_stream'}
);

PhantomJS doesn't send authentication header

I'm trying to open a web page which requires HTTP authentication, in PhantomJS.
My script is based off the loadspeed.js example:
var page = require('webpage').create(),
t, address;
page.settings.userName = "user";
page.settings.password = "password";
if (phantom.args.length === 0) {
console.log('Usage: loadspeed.js <some URL>');
phantom.exit();
} else {
t = Date.now();
address = phantom.args[0];
page.open(address, function (status) {
if (status !== 'success') {
console.log('FAIL to load the address');
} else {
t = Date.now() - t;
console.log('Loading time ' + t + ' msec');
page.render('page.jpg');
}
phantom.exit();
});
}
I can see from the rendered page.jpg that I'm getting a 401 every time.
I've also traced the HTTP session using Wireshark, which reveals that no authentication header is sent in the GET request to the given URL.
What am I doing wrong here? I'm just getting started with PhantomJS but I've been searching all evening and not gotten far...
PhantomJS (at least as of 1.9.0) has a bug with auth: it sends the request without the auth headers, and then only after it gets the 401 back does it do the request again but this time with the headers. (That is for GET; with POST it doesn't work at all.)
The workaround is simple, so instead of:
page.settings.userName = 'username';
page.settings.password = 'password';
you can use:
page.customHeaders={'Authorization': 'Basic '+btoa('username:password')};
(I just covered this in a blog post: http://darrendev.blogspot.jp/2013/04/phantomjs-post-auth-and-timeouts.html, and learnt that workaround on the PhantomJS mailing list from Igor Semenko.)
I dont think there is anything wrong with the script your using or phantomjs (at least in v1.5).
If you try this script:
var page = require('webpage').create(),
system = require('system'),
t, address;
page.settings.userName = 'test';
page.settings.password = 'test';
if (system.args.length === 1) {
console.log('Usage: loadspeed.js <some URL>');
phantom.exit();
} else {
t = Date.now();
address = system.args[1];
page.open(address, function (status) {
if (status !== 'success') {
console.log('FAIL to load the address');
} else {
t = Date.now() - t;
console.log('Page title is ' + page.evaluate(function () {
return document.title;
}));
console.log('Loading time ' + t + ' msec');
}
phantom.exit();
});
}
phantomjs loadspeed.js http://browserspy.dk/password-ok.php
The auth is successful.
