Question

I’ve been trying to get Rails to play with the new Facebook Graph API. After I get the authorization “code”, I need to send another request which returns the access token in JSON form.

It seems to work fine, however I want to fetch the access token JSON without redirecting the user. I’m attempting to use Net::HTTP.get, but I’m not sure how to use it to get a request body, or even if it’s the right thing to use to begin with.

Can anyone give an example of performing an HTTP GET?

Answer 1

I’ve figured out how to do this, the problem was mainly with the fact that I needed an HTTPS connection.

Adapted from http://snippets.dzone.com/posts/show/788:

path = '/oauth/access_token?...'
http = Net::HTTP.new('graph.facebook.com', 443)
http.use_ssl = true
res = http.get(path, nil)
@access_token = res.body

Anyone specifically trying to use the Graph API, note that the value stored in @access_token is in the form of a params string, e.g. “access_token=xxxx&expires=1234”.

I got around needing to parse this by just redirecting to another page and using that as the URL params, but there’s probably a better way to do this.
