Hi, i'm using fbgraph module to connect with facebook, i've this code:
// Set index route
app.get('/', utils.accesslog, function(req, res){
//Get token from session to allow post
graph.setAccessToken(req.session.fb_token);
console.log(req.session.fb_token);
var wallPost = {
message: "Hello!"
};
// To post you need to authorize the applicationt to public_stream:
http://facebook.com/authorize.php?api_key=MYAPPAPIKEY&v=1.0&ext_perm=publish_stream
graph.post(req.session.fb_userId + "/feed", wallPost, function(err,
results) {
// returns the post id
if (err){
console.log(JSON.stringify(err)); // { id: xxxxx}
}else {console.log(JSON.stringify(results));}
});
res.render('index', {connected: req.session.connected, title:
configuration.Params.title, message: [{msg: "Hello" + req.session.fb_userId}]});
});
// Set facebook login path. On Facebook main parameter page set url as:
mysite.tld/fblogin
app.get('/fblogin', utils.accesslog, function(req, res){
// we don't have a code yet
// so we'll redirect to the oauth dialog
if (!req.query.code) {
var authUrl = graph.getOauthUrl({
"client_id": configuration.Params.facebook_appId,
"redirect_uri": configuration.Params.facebook_redirect_uri
});
if (!req.query.error) { //checks whether a user denied the app
facebook login/permissions
res.redirect(authUrl);
} else { //req.query.error == 'access_denied'
res.send('access denied');
}
return;
}
// code is set
// we'll send that and get the access token
graph.authorize({
"client_id": configuration.Params.facebook_appId,
"redirect_uri": configuration.Params.facebook_redirect_uri,
"client_secret": configuration.Params.facebook_secret,
"code": req.query.code
}, function (err, facebookRes) {
console.log(facebookRes);
req.session.fb_token = facebookRes.access_token;
// Get user information and put them into session
graph.get("me", function(err, user) {
req.session.fb_userId = user.id;
console.log(user); // { id: '4', name: 'Mark Zuckerberg'... }
res.redirect('/');
});
});
});```
I have two request to facebook:
{"id":"1657787844_3625402647858"}
{"message":"(#506) Duplicate status
message","type":"OAuthException","code":506,"error_data":{"kError":1455006}}
It seems that pages is refreshed twice, sometimes facebook post each message,
so i've duplicate messages on board.
Could someone help me on this problem?
Thanks for your time.
Best regards.
