Which is profile url and which is community url, how to find?

Answer 1

Well as @Lix has suggested you could do something like this:

Request: https://graph.facebook.com/BryantAthletics?fields=gender

HTTP Response: 400 Bad Request

JSON Response:

{
   "error": {
      "message": "(#100) Unknown fields: gender.",
      "type": "OAuthException",
      "code": 100
   }
}

This tells us its NOT a User object. But then it could be a group or a page.. So you need to make another request using an attribute that is unique either to a group or page. Depending on how you make the request, you could decide to handle the result accordingly.

Consider,

Request: https://graph.facebook.com/adelphi.panthers?fields=gender

HTTP Response: 200 OK

JSON Response:

{
   "gender": "female",
   "id": "1360823630"
}

Now this tells us that the gender attribute exist within this Facebook object and so it is definitely a user.

I’m assuming you are using JQuery to capture and parse the response. Then you would check for the error attribute in the JSON variable to determine the object type.
