This seems like a pretty obvious, basic thing to expect from the Graph API, but I'm having serious difficulty with it. All I want to do is get the ID for any particular URL. They have a method for this:
https://graph.facebook.com/?ids=http://www.imdb.com/title/tt0117500/
And that works great. But if I try another URL, say for my blog,
https://graph.facebook.com/?ids=http://dusda.vox.com
it doesn't give me back a numerical ID like all of the examples do. Instead, this:
{"http:\/\/dusda.vox.com":{"id":"http:\/\/dusda.vox.com"}}
If I try to use that "id", I get jack (probably because the query string looks impossible to parse):
Request: https://graph.facebook.com/http://dusda.vox.com/likes
Response: {"id":"http:\/\/dusda.vox.com\/likes"}
So what's up with this? Is the Graph API just selectively reliable, or am I misunderstanding something? I've tried it on URLs that I know are popular on Facebook, too, and I've gotten mixed results.
