Posting a Post through Facebook Graph Node JS - node.js

Question

I'm currently looking to automate a few tasks by creating a custom application that allows me to easily post status updates on my Facebook page(not my personal timeline). My backend is running on NodeJS.
My client-side code has the following:
window.fbAsyncInit = function() {
FB.init({
appId : 'xxxxxxxxxxxxx', // App ID
channelUrl : '//xxxxxxxxxxx, // Channel File
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true // parse XFBML
});
// Additional init code here
FB.getLoginStatus(function(response) {
if (response.status === 'connected') {
console.log("You are signed into FB");
var access_token = FB.getAuthResponse()['accessToken'];
console.log('Access Token = ' + access_token);
FB.api('/me/accounts', function(response) {
for(var i=0;i <response.data.length;i++){;
var page = response.data[i];
if(page.id==my_id){
var page_token = page.access_token;
console.log(page_token);
var param = 'callback=?&username=' + GetURLParameter('username')+'&session='+ GetURLParameter('session')+'&access_token='+ page_token;
$.post(saveTokenEndpoint, param, function(data) {
console.log(data);
});
}
}
});
FB.api('/me', function(response) {
username = response.name;
userid = response.id;
$('#username').text('~Hi '+username+'!');
$(document).trigger('fbInit');
});
// connected
} else if (response.status === 'not_authorized') {
// not_authorized
login();
} else {
login();
// not_logged_in
}
});
};
// 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/en_US/all.js";
ref.parentNode.insertBefore(js, ref);
}(document));
function login() {
FB.login(function(response) {
if (response.authResponse) {
console.log("You are signed into FB");
var access_token = FB.getAuthResponse()['accessToken'];
FB.api('/me', function(response) {
username = response.name;
userid = response.id;
$('#username').text('~Hi '+username+'!');
$(document).trigger('fbInit');
});
FB.api('/me/accounts', function(response) {
// handle response
for(page in response.data){
if(page.id==my_id){
var page_token = page.access_token;
console.log(page_token);
var param = 'callback=?&username=' + GetURLParameter('username')+'&session='+ GetURLParameter('session')+'&access_token='+ page_token;
$.post(saveTokenEndpoint, param, function(data) {
console.log(data);
});
}
}
});
} else {
// cancelled
}
}, {scope: 'publish_stream, manage_pages, offline_access'});
}
My server-side code:
// saves the token received for future use in posting
app.post('/api/saveToken',function(req,res){
var username = req.body.username;
var access_token = req.body.access_token;
var session = req.body.session;
user.findOne({
username: username,
session: session
},function(err, userObj){
if(userObj!=null){
userObj.token = access_token;
console.log(access_token);
userObj.save();
res.jsonp({status:'true'});
}else{
res.jsonp({status:'false'});
}
});
});
I'm using this method to post my posts on my page:
var data = querystring.stringify({
access_token: token,
message: message
});
var options = {
host: 'graph.facebook.com',
port: 443,
path: '/app_name/feed',
method: 'POST',
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
'Content-Length': data.length
}
};
var req = https.request(options, function(res) {
res.setEncoding('utf8');
res.on('data', function (chunk) {
console.log("body: " + chunk);
});
res.on('end', function(){ // see http nodejs documentation to see end
console.log("\nfinished posting message");
conObj.approval = 'published';
conObj.save();
});
});
req.on('error', function(e) {
console.error(e);
});
req.write(data);
req.end();
Current situation:
My code is working and i can actually see the posts on the wall of my page.
BUT
It does not appear to anyone else except myself.
HOW I GOT IT TO APPEAR PROPERLY TEMPORARILY:
When i copy the token directly from the Graph API Explorer(/me/accounts), I got it to work.
https://developers.facebook.com/tools/explorer?method=GET&path=me%2Faccounts
Ultimately, all i want to do is find a way to post a post on my page
I monitored the differences that was made through both tokens and have found no differences. Their scope was to the 'public' and 'everyone'.
Experts do advice! I find this all very puzzling.
I'm intending to try NodeJS facebook such as facebook-node-sdk and nodejs-facebook-sdk libraries if all else fails.
Thanks for the replies in advance!

You should do OAUTH server side, not client side.
Here is a working example of posting a post through the Facebook Graph API using node.js here: http://code.runnable.com/facebook/UTlPM1-f2W1TAABY
The only dependency you're not already using is request, which you should be using.
