If a user has signed on to my web app with their Facebook login, how do I remove them again?
The result would be that, if they tried to log in again, then they would be asked if they wanted to add my app along with the permissions, etc.
This is server side so I need the url, something along the lines of
https://graph.facebook.com/me/?access_token="+access_token
Edit: clarification above
If you are trying to do what I'm trying to do, which is sort of "Start over", your best bet is to just register a new Facebook APP. In other words, delete the current one and get a new APP ID.

I have Facebook page widget, and i want to track if user liked my page or not. If not then force them to like. I did code for that, but now issue is when user try to like page and not logged in, Facebook open login window and app id is different on that window(which is default, don't know from where it takes).
And because of that, users not able to authorize my app. And i cant track details of that users.
Make sure you are using Page Plugin, instead of the now-deprecated like box. It's hard to say without seeing any code, but it sounds like you are either using the SDK/plugin incorrectly, or using something like a 3rd party wordpress plugin that may be acting maliciously by injecting another ID.
I am working on a local application that needs to retrieve data from user's Facebook profile. As long as I can see, by default I can only get name, picture and age range, but I need many others information like education, location, likes and so on. I tried to submit approval for these items, but Facebook won't set my submission because I don't have a Privacy Policy URL added. I don't know what Privacy Policy URL to add because I'm working on localhost.
Please help me figure it out and excuse me if my question is wrong, it's the first time when I work with fb api. Also, if there is another way to retrieve this items, I would be more than happy to hear about it.
Have a look at
https://developers.facebook.com/docs/apps/review/login#do-you-need-review
It's saying that
in order to help you craft your Facebook Login experience, your app's developers will be able to see, and grant, any permission without requiring review by Facebook.
and
Also, if you're the developer of an app and are the only person using it, then your app doesn't need to go through review. Since you're the developer, all app capabilities should be available. You will still need to take your app out of developer mode, but you should be able to do that without going through review.
So, to be able to develop your app and request extended permissions, you don't need to pass your app to review, as long as you test with an app admin/developer/tester.
I have an existing app that uses the Facebook API & login that makes posts to the user's wall. For each post I store the id of that post.
What I need to accomplish is to gather like counts of those posts generated by the first app. I'm trying to write a small app that routinely pulls the like count. I've figured out how to get the like count of the post if I use a User Token - via Facebook Login. But since this app will run as a batch and not by a human, I don't want to use a Facebook login page. I could write code that simulates a user logging in but that would be a major ugly hack. I've tried to use an App Token but then the like count is always zero. I've found how to get the like count of a page without the need for a User Token http://www.techrecite.com/get-facebook-likes-count-of-a-page-using-graph-api/ but not a post
Is this even possible? If so how?
I've looked into Facebook API's subscription, but it doesn't seem possible to subscribe to a "like-a-post" event. Although I could be wrong. If so, could someone point me in the correct direction.
Thanks.
Basically what I'm doing is building a desktop application that needs to connect to a web server, perform some calculations, and then have the resulting values sent back to it. The calculations change over time, and also need to stay somewhat secure, which is why I'm not just coding them into the desktop application.
The issue is that only authenticated users should be allowed to access the server. So what I'm looking for is a way to log-in to Django from my desktop application (i.e. the desktop application will pop up a window asking for a username and password, which will then be sent to the Django site, used to authenticate the user, and if valid, will return the results of the computation. It also needs to work as a session (the user enters their password at the beginning and then doesn't need to log-in again until they close the desktop application, even if multiple computations are performed).
I think I need to use session keys for this, and perhaps the RemoteUserMiddleware described here but I really have no idea where to start as far as coding this. Any suggestions or pointers in the right direction would be hugely appreciated.
Thanks,

P.S. If this is important, the desktop application is written in VB.NET.
Interesting. I've never done anything like this, but here is, what I assume, is the basic idea:
1) Get a good view of Django sessions; the basic idea is:
One logs in using the django auth framework login service
Django will create a session for you and handle all the difficult stuff
Django returns a HttpResponse with a sessionid cookie. You will need to send this back with any request following to identify yourself and 'operate within the session'.
One logs out using the django auth logout service and the session is destroyed by Django.
2) Now, the rest is relatively easy.
Setup django urls.py with the appropriate urls for login/logout + computation service
Execute a post request to the login service with the appropriate parameters set
Catch the response, extract the 'sessionid' cookie and save it somewhere
On each subsequent request, include the sessionid
This should get you started. Good luck!
I'm soon to write a web based Twitter client which I plan to allow users to login with OAuth. My question is; can, once a user has logged in once already, my app login later and 'background' process their feed for them? I.E. does the user have to 'be there'?
Yes, when they have autorized the login you can keep them loggedin. Just like applications like tweetdeck do. Check out http://hueniverse.com/2007/10/beginners-guide-to-oauth-part-i-overview/ for a walkthrough.
