Different Facebook access token JavaScript SDK - facebook

Question

I'm quite confused with the access token from facebook..here is how I obtain the user's access token and use it to get data from graph API
window.fbAsyncInit = function() {
FB.init({
appId : 'app ID',
status : true,
cookie : true,
xfbml : true,
oauth : true,
});
FB.getLoginStatus(getStatus);
FB.Event.subscribe('auth.authResponseChange', getStatus);
function getStatus(response) {
if ( response.status === 'connected' ) {
var accessToken = response.authResponse.accessToken;
console.log("accessToken = " + accessToken);
$.ajax({
dataType : "jsonp",
type : "GET",
url : "https://graph.facebook.com/me/albums?access_token=" + accessToken,
success : function(data) {
$.each(data, function(index, value) {
console.log(index + ": " + value);
})
}
});
}
}
};
However, I always get an empty data. After I visit the graph API documentation here: https://developers.facebook.com/docs/reference/api/ and click on one of the graph links, I notice that the access token generated there is always different from what I retrieve from my code. For example, the current access token in the graph api documentation is
"AAAAAAITEghMBAMwuyHZCO3VOAvCm9hHpaZC9PGV9238ixsZB7zSfuplZBTZCLRj6cEViZADJlVcjOfInwvcbhqu3XBF1w4ZAxvPbexcGQZAYzb4bHAKsMbLF"
and the one in console log is
"AAAG0ZCFantJ8BAAFcMdDOyDyT4OBtjrvULEaS2o94gZAU7U1xITaogFXCZBghQP8G9bjEh3XSCATQOZCUSZCuNWFvEfypIAmcz9bkbk5qRBlHUZAOE4guW"
I think that I may have done this the wrong way. Can anyone help explain to me how to retrieve data from graph API in a correct way?
Any kinds of help will be appreciated. Thanks in advance :)

Answer 1

Run this URL with your authToken first:
https://graph.facebook.com/me/permissions?access_token=USER_ACCESS_TOKEN
You'll almost certainly only see basic permissions in the response, which is why you aren't getting the data from your call to the user's album.
You'll then want to run your user through the Authentication Process, making sure you request the permissions you need (probably 'user_photos' in your case).
More info is available in those two links. Good luck!

Answer 2

access token will never be the same. So that behaviour is correct.
Back to your problem , I think its mostly scope related issue.

Answer 3

I had developed a application using facebook c# sdk, In that application i did it like this:
when a post is to be submitted , redirect the user to facebook (with some parameters like appid, app-secret, auth-token and
redirect-url);
Facebook will ask the user to login with his credentials.
When the user is logged in, facebook will redirect back to the redirect-url. (with the authtoken and a new auth-code).
Then we should use this auth-code, app-id and app-secret and obtain the user-access-token. (This is done by doing a rest api call to the
url
https://graph.facebook.com/oauth/access_token?client_id=client_id&redirect_uri=redirect_uri&client_secret=client_secret&code=auth-code
This will return the user-token and expiry time for the token
And then we can post using this user-access-token to the fb.
Initially i had misunderstood the auth-code and used it as the user-access-token, and i always got the result as unauthorised token .
Please check whether this will help you or not.
